General Safety

Read and be familiar with all safety protocols and procedures before operating any machinery. It is the
responsibility of the operator to ensure all safety precautions are correctly followed and the machine is
properly assembled and in working order.

ALWAYS inspect the laser cutter for damage or breakage before each use. Do not

operate machinery that is damaged or defective in any way.

ALWAYS have a clean, level, and open work space to unbox and place your laser cutter

ALWAYS be aware that the laser tube is made of glass and is therefore extremely

fragile and can cause severe lacerations if broken.

ALWAYS be aware that the laser tube is lled with CO2 gas. While carbon dioxide is a

class 2.2 gas (nonammable and nontoxic), release of this gas from the laser tube will

render your laser inoperable.

NEVER modify, disassemble, or in any way alter the construction of the laser and never

start up a system that has been modied or disassembled.

NEVER leave the laser system unattended during operation.

KEEP YOUR LASER SYSTEM CLEAN – A build up of cutting and engraving

residue and debris is dangerous and can create a re hazard. Keep your laser system

clean and free of debris. Regularly remove the cutting grid to clean any small pieces
that have gotten stuck or fallen through.

DO NOT disassemble the machine or remove any of its protective covers.

NEVER place hands or ngers into moving parts such as cooling fans.

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

Laser Safety

The output of the CO2 engraving laser is fully contained in a Class 1 enclosure during normal
operation. The laser cabinet has a safety interlock switch that deactivates the laser if the door is
opened during operation, and no special precautions are necessary to operate the high power
laser safely. However, the output beam of the Alignment Laser (visible red diode laser) is accessible
to the operator during normal operation, giving the total system an overall rating of Class 3R.
Class 3R lasers have minimal safety concerns when used properly and handled with care.

Follow these safety guideline at all times:

NEVER

portion of the cabinet will expose the laser system and greatly increase the risk of injury and/or

re. Personal injury and re risks are especially pronounced if the machine is operated with the

bottom panel removed. Remember that the CO2 laser beam is invisible!

operate the machine with any of the panels removed. Be aware that removal of any

NEVER engrave or cut any material containing PVC or vinyl. These materials (along with other

chlorine/ chloride containing materials) produce a corrosive vapor that is extremely harmful to
humans and will destroy your machine. Your warranty will be void if your machine is damaged
by corrosion from engraving or cutting PVC or vinyl.

NEVER engrave or cut any unknown material. The vaporization/melting of many materials,

including but not limited to PVC and polycarbonates, can give off hazardous fumes. Please refer
to the MSDS sheet from the material manufacturer to determine the response of any work

material to extreme heat (burning/re hazard).

ALWAYS use the air assist, especially while vector cutting. Vector cutting movements are

relatively slow and apply an extremely large amount of heat to the workplace. This buildup of

heat can create a signicant re risk.

NEVER run laser with lid open. Always be sure the lid is closed and never tamper with lid

safety mechanism.

NEVER operate the machine without a properly operating ventilation system. Most materials

produce an irritating smoke when engraved. Some materials, including but not limited to: paint,
varnish, composition board, and plastics, produce compounds that can be harmful if concentrated.

NEVER look into the beam of the Alignment Laser (visible red diode laser).

NEVER aim any laser towards an aircraft or vehicle that is in motion. The bright light can

ashblind,cause glare, or distract the pilot or driver.

Laser Safety (Cont.)

The standard reference for laser safety is the American Standard for the Safe Use of Lasers,
Z136.12000, developed by the American National Standards Institute (ANSI). This reference is
the basis for many of the federal regulations for laser and laser system manufacturers, and for the
Occupational Safety and Health Administration (OSHA) laser safety guidelines. It contains detailed
information concerning proper installation and use of laser systems. While the ANSI standard itself
does not have the force of law, its recommendations, including warning signage, training, and the

designation of a laser safety ofcer, may be compulsory under local workplace regulations when
operating laser systems above Class I. It is the operator’s responsibility to ensure that the installation

and operation of the Full Spectrum Laser Hobby Laser System is performed in accordance with all
applicable laws. Copies of ANSI Standard Z136.12000 are available from: LASER INSTITUTE OF

AMERICA 12424 RESEARCH PARKWAY, SUITE 125 ORLANDO, FL 32826 (407) 3801553.

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

Fire Safety

Laser cutting and engraving systems can present a signicant re hazard due to the extremely

high temperatures generated by the laser beam. While the objective of most cutting and engraving
operations is to vaporize material without burning, most materials capable of being cut or engraved

are inherently combustible and can ignite. Usually this is a small ame of burning material issuing

from the cut zone which self extinguishes due to the air assist or depowering of the beam. However,

it is possible for the ame to propagate and set re to the machine and its surroundings.

ALWAYS keep a properly maintained and inspected 5lb or larger re extinguisher on hand.

Full Spectrum Laser recommends a Halogen re extinguisher or a multipurpose dry chemical re

extinguisher. Halogen extinguishers are more expensive than a dry chemical, but offer certain
advantages should you ever need to use an extinguisher. The Halogen extinguisher discharges a
clean, easily removable substance that is not harmful to the mechanics or wiring of the laser system.

The dry chemical extinguisher discharges a sticky, corrosive powder that is very difcult to clean up.

BE AWARE that stacking materials (especially organic materials such as paper) can lead to

increased risk of ame propagation or work piece ignition.

NEVER operate your machine unattended. There is a signicant risk of re if the machine is set

improperly, or if the machine should experience a mechanical or electrical failure while operating.

ALWAYS keep the area around the machine clean and free of clutter, combustible materials,

explosives, or volatile solvents such as acetone, alcohol, or gasoline.

ALWAYS use air assist when vector cutting.

BE CAREFUL when vector cutting. Many materials have the potential to burst suddenly into

ames – even materials that may be very familiar to the user. Always monitor the machine when

it is operating.

PRO TIP! Experience shows that vector cutting with the laser

has the most potential to create an open ame. Acrylic in all
its different forms has been shown to be especially ammable
when vector cutting with a laser.

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

Fire Safety (Cont.)

NEVER CUT PVC (polyvinyl chloride) under any circumstances: fumes are highly toxic

and potentially lethal.

NEVER store any ammable materials in the inside of the device or in the immediate vicinity of

the device. Debris and leftover produced materials within the machine must to be removed to prevent

re hazard.

ALWAYS have on hand a rst-aid kit designed for the initial treatment of burns and smoke

inhalation. Be sure to store this kit in an area that is outside risk areas.

Woodshop Dust Fire Safety Considerations*

Before processing materials the user must verify whether harmful materials can be generated

and whether the lter equipment of the exhaust system is suitable for the harmful materials. We

emphasize that it is the responsibility of the user to consider the national and regional threshold

values for dust, fogs and gases when selecting the lters and the exhaust system.

(The values for the maximum workplace concentration must not be exceeded.)

Be mindful of large quantities of fuel in the form of wood and wood products, sawdust, and

ammable materials such as paints, oil nishes, adhesives, solvents, and liquid propane for

internal combustion engines.

Preventing the buildup of dust is one of the key means for controlling re and explosion hazards.
The principal engineering control technology for control of dust is exhaust ventilation. The primary
work practice control is good housekeeping.

Dust collection is best accomplished at the source-at the point of operation of the equipment, if
feasible. For many pieces of equipment, well-designed ducts and vacuum hoods can collect most
of the dust generated before it even reaches the operator.

Very ne dust that manages to escape point-of-source collection can be captured from above by
general exhaust points located along the ceiling. These control technologies are effective for most

equipment, excepting machines that commonly produce the very nest dust or large quantities of dust.

*These guidelines come from the U.S. Department of Labor

Electrical Safety

The power supply is capable of outputting DC 20,000V at up to 20mA. This power is also provided to
the discharge terminals on the laser tube itself. Your laser shipped with silicone terminal covers that
prevent access to bare wiring—notify Full Spectrum Laser support and immediately cease operations
if these covers ever slip and expose bare wire.

DO NOT open any of the machine’s access panels while the unit is plugged in. Opening a panel

may expose the operator to the unit’s AC input power. The AC input power is potentially lethal and is

located on the far right within the cabinet.

NEVER make or break any electrical connections to the system while the unit is turned on.

NEVER access the electronics area with hands or tools unless the unit is disconnected from power

for at least one hour.

NEVER replace the installed 10 amp fuse with a fuse of a higher rating. This will void your warranty

and the electronics will not be adequately protected from surges or short circuits.

POWER ON/OFF is controlled by the switch at the back of the machine. To power the machine on,

press the (-) side down. To turn power off, press the “o” side down.

IN CASE OF A BLOWN FUSE always contact Technical Support before replacing any fuses.

SECTION II. UNBOXING YOUR MUSE

When your Muse arrives, it will require careful unboxing and examination of parts. Follow these
instructions for best results. Note that if you purchased a Coolbox with your muse, you will be directed
to Appendix A: Coolbox Assembly for unpacking instructions

FRAGILE PARTS! Be gentle in removing the foam packaging and

accessories. Never pull or force the packaging loose from the laser
cutter. Be particularly aware that the water inlet and outlet nodes
protrude from the tube and are extremely fragile when unboxing
your laser tube.

Unboxing Steps

Now that your Muse has arrived, it will require careful unboxing and examination of parts. You will
need two able-bodied adults to lift and place the machine.

Follow these instructions for best results:

1. Prepare Work Space:

solid table with adequate room for the machine is recommended (the machine’s dimensions are 32”

x 20” x 8.75”). Be sure the table is free of clutter and can support a minimum of 100 lbs (the machine
weighs 70 lbs on its own).

You will need an open, level work space to place your laser cutter. A

2. Place Box: Set the box on a at space near where you will place the machine (such as the

oor). Open the box carefully from the top. If you use a cutting tool to open the box, be careful not to

allow the cutting edge to cut past the cardboard box. Always use all tools with caution and only as

specied by the manufacturer.

3. Remove Packaging: Gently remove the following from the box: the honeycomb plate, the

Quick Start Guide and the top (4) foam pieces securing the machine.

4. Remove Accessories: Nestled in packing foam, inside the interior of the machine, are the

following parts and accessories: a plastic bag with cords and small accessories, the water pump
and the air compressor. Inspect these parts to insure they are accounted for and intact.

5. Place Muse: This will require two adults as the machine weighs approximately 70 lbs. Standing

on both ends, grip the machine from the bottom and gently lift the machine out of the box, leaving the

bottom foam still inside the box. Place on the clean, at table you plan on keeping it. Your Muse is

now unboxed.

6. Inspect your Muse: If have any questions, contact your sales representative or

customer support. Refer to your Muse Quick Start Guide or download the Muse User Manual for
assembly instructions.

Assembly Stage 1: Locate & Remove Zip Ties

To secure the machine during shipping, yellow zip ties are used to hold the laser head assembly and the

x-gantry. These zip ties must be removed before operating your laser cutter for the rst time.

Figure 3.2

1. Locate Yellow Zip Ties: Yellow zip ties secures the laser head and x-gantry during shipping.

Open the lid and identify all yellow zip ties.

2. Cut and Remove Yellow Zip Ties: Using a small pair of scissors (nail cutters work remarkably

well), carefully cut and remove ALL yellow zip ties. DO NOT cut any other cord or wire. Be aware that the
glass laser tube is extremely fragile. Be careful NOT to damage any part of the machine during this process.

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

15

Assembly Stage 2: Connect the Exhaust System

It is required that an exhaust fan is connected and operating whenever you run a job on your laser.
A properly installed exhaust fan removes smoke and fumes from the case and exhausts them to the
outside of the building or a fume extractor. For Coolbox users, skip this step and refer to Appendix A:
Coolbox Assembly.

1. Position Ducting: Place your 4” ducting over the Exhaust Port located at the back of the

machine and hold. Secure with 4” ducting clamp.

2. Attach Exhaust Fan: Secure the other end of the ducting, connected to the machine, to the

exhaust fan. Now repeat the ducting and clamping process on the other side of the exhaust fan,
creating a sequence of machine to ducting to exhaust fan to second ducting. Now plug in the exhaust
fan into the bottom power plug marked “exhaust” on the back of your Muse machine.

3. Ventilate Outside: Set the open end outside of a window or an installed ventilation outlet.

Check your system for leaks—most can be remedied with duct tape. Please be aware that the
protective housing is not designed to be airtight; the front grill is designed to allow an exhaust
system to draw fresh air through the work area.

4. Connect to Power: Plug the exhaust fan power cord into the lower power plug marked

“exhaust fan” on the back of your Muse. Note that accessories plugged into the back of your Muse will

only turn on when the laser is red (as intended to save power).

5. Fume Extractor Upgrade (optional): You can also upgrade to a fume extractor. Fume

extractors are air purifers that clean the air through HEPA Filters. Fume extractors do not require
outside ventilation. This is a great option for workshops that do not have the option to ventilate

outside. Both the extractors and the ters are available on the Full Spectrum Laser website at

https://www.fslaser.com/Products/LaserAccessories. Ask a customer support representative which
fume extractor is right for your needs.

Small Fume Extractor

Fume Extractor lters require routine cleaning and replacement, dependent on use and materials cut.
Generally, fume extractor suction will diminish and odors will be detected as lters clog.

Medium Fume Extractor

Large Fume Extractor

NEVER use a fume extractor without all lters in place.

Follow these maintenance guidelines:

Pre-Filters

Clean often. Use a shop vacuum to clean as debris builds. Check weekly, especially if cutting a lot of
wood. When accumulated debris remains over 70% after cleaning, replace Pre-Filter.

HEPA Filters

Clean immediately when suction is reduced. Use a shop vacuum to clean accumulated dust. When
cleaning does not return optimal suction power, replace HEPA Filter.

Activated Carbon Filters

Clean when odors are detected or suction is reduced. Gently shake excess dust and debris from

carbon lter and follow with a shop vacuum. When cleaning no longer eliminates detectable odors,

replace Activated Carbon Filters.

Assembly Stage 3: Assemble the Water System

Muse uses a water-cooled continuous beam CO2 laser tube. The tube requires a ow of room

temperature water to regulate the temperature of the laser tube. Your purchase includes
a water pump for cooling the laser tube. For Coolbox users, skip this step and refer to Appendix A:
Coolbox Assembly. Coolbox users will not need a bucket.

Never Fire the Laser: Without a correctly connected and

powered water pump. Firing the laser without turning the pump
on or, worse, with no water in the system,will severely degrade
or destroy your laser tube and void your warranty.

1. Remove Capping On Water Inlet /Outlet: Remove the short silicone tubing, capping

the water inlet and outlet on the back of the machine.

2. Attach Water Pump Fitting: Remove the water pump from its packaging. Attach the

plastic tting to the water pump by gently screwing it on.

Figure 3.7

3. Prep Water Bucket: Fill a clean 5 gallon bucket (not included) with 3 - 4 gallons of distilled

water (not included). ALWAYS use only distilled water and replace often. It is recommended that you

choose a bucket with a lid and cut holes to allow the tubes to t. This will prevent debris falling into

your water bucket.

Assembly Stage 4: Assemble the Air Compressor

Air is used as a pressurized gas to assist in cutting and engraving operations. This pressurized

air is critical to safe and efcient cutting operations as it not only helps cut through material more
quickly, but also helps prevent the formation of ames. For Coolbox users, skip this step and refer to

Appendix A: Coolbox Assembly.

1. Attach Push Fitting: Remove the air compressor from its packaging. Gently attach the air hose

push tting to air compressor.

Figure 3.13

2. Attach Air Hose to Air Compressor: Push one end of the black air inlet hose into the air

compressor push tting until it is snug.

PRO TIP! We recommend that you attach the laser and water

pump to a power strip and use that to control the mains power

to the unit - this ensures that the water pump is always on when
the laser is powered.

CAUTION! Make sure that there are no air bubbles inside

of the water jacket of the laser tube. Air bubbles can create

local hot spots in the lasing chamber and reduce the lifetime

of your tube. If present, water bubbles typically migrate
to the electrodes on either end of the tube. You should
visually inspect the laser tube to make sure that bubbles are
not present; slightly tilting the laser while powering on the
circulation pump is usually sufcient to remove bubbles.

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

Assembly Stage 5: Connect Electrical Power

Muse’s Laser System, and available accessories, are congured to accept 110VAC at 60Hz. 220VAC

units connect to power through an included converter (single-phase 220VAC).

1. Prepare Power Cord: Remove the electrical cord from its packaging.

2. Plug in Power Cord To Laser Cutter: The power cord plugs into a “C14” power receptacle

located on the right side of the machine.

3. Plug in Power Cord to Outlet: Plug the power cord into any proper outlet socket

in your workspace.

Figure 3.16

PRO TIP! Please be aware that the accessories will increase the circuit

load; the most signicant power draw usually comes from the blower/
exhaust system. Consult the manufacturer’s information and manual for
the operating parameters of your exhaust system.

IN CASE OF A BLOWN FUSE: The laser system is equipped with

a fuse on the power inlet to protect the machine from surges or short

circuits. If this fuse ever needs replacement, please contact Full
Spectrum Laser technical support.

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

24

Assembly Stage 6: Connect the Ethernet Cable

Muse software is browser-based, which means there is nothing to download. With any Mac or
PC, you only need an internet browser (such as Google Chrome) to access the latest version of
RetinaEngrave 2.0. The easiest method is to connect the Ethernet cable that came with your Muse.

1. Identify the Ethernet Cable: Locate and remove the included Ethernet cable

from its packaging.

2. Plug Ethernet Cable into Laser Cutter: Plug in the Ethernet cable into the Ethernet

slot on the Muse.

3. Plug Ethernet Cable into Computer: Plug the other end of the Ethernet cable into your

computer’s Ethernet slot.

4. Connect Via Router (Recommended): Router connectivity is more reliable than

directly connecting via Ethernet and should be the primary way of connecting. Direct connect from
laser to computer should be a secondary choice, if possible. If direct connecting to router is not
available (i.e. due to location of router) then we recommend using an Ethernet to Wi-Fi adapter
that is connected to the router. If both of those are not possible then direct connection to computer
can be utilized via the Ethernet cable.

PRO TIP! Muse can connect to your computer via either Ethernet

or USB (but not both simultaneously). Full Spectrum includes an

Ethernet cable in the laser accessories and recommends the use

of Ethernet cables as USB is more prone to electrical interference.

ATTENTION! Your laser must be connected to your computer

in order to download jobs. The laser can store jobs in its onboard
memory while powered, however loss of power will cause stored
jobs to be lost. If you purchase and install a USB device, you can
download jobs to your laser and run them without a computer
attached (however you will not be able to alter the job settings
from the laser control panel). Because a USB device is not volatile
memory, jobs are stored between power cycles.

PRO TIP! If your laser is located more than 6ft from your

computer, you will need to use the Ethernet connection.
Connecting via Ethernet while the power is on requires you to
power cycle your machine in order to obtain an IP address.

Assembly Stage 7: Connect to Software

RetinaEngrave 3.0 is a combination of a print driver and control software that communicates with,
downloads jobs to, and controls the laser system. There is no download required for RetinaEngrave

3.0. With a local connection (achievable with Wi-Fi or an Ethernet cable) your Muse software will be
available for use within your web browser

1. Turn On Laser Cutter: Turning on your laser will automatically boot up the Touch Screen

interface. Allow 30 seconds or so for the machine and touch screen to boot up.

2. Access the Application: If your network supports “Bonjour” technology (DNS­SD) simply navigate to the following address to access the application: “fsl.local/”.

-OR-

3. Note the Device Address: This will be visible on lower left corner of LCD and will vary

depending on connection type (ethernet/wi).

4. Type IP Into Browser: Type this IP number into your favorite browser (Google Chrome is
recommended) and press the enter key. This will link you to the RetinaEngrave 3.0 interface.
You now have full access to the software. There is no need to install or download anything.
You must, however,keep a local connection to the device while operating the software, either
through Wi-Fi or the Ethernet cable.

Connection Methods

1. Ethernet (Preferred): Connect your Muse unit to your local router or switch using an ethernet
cable. The device IP address may be assigned automatically in most cases as supported by
your local network. In cases where no DHCP server exists, you may statically assign an IP
address from the LCD or the web application options menu.

2. Wi: Connect you Muse to a local wireless network via the LCD or web application.

3. HotSpot: Connect your PC, laptop, or tablet directly to the wireless network hosted by the unit.

4. Direct (Link-Local) Ethernet Connection: Connect an ethernet cable directly from your PC or

laptop to the device.

RetinaEngrave 3.0 Print Drivers

RE3 users can download the RE3 print drivers from the Full Spectrum Laser website in order to send

device-specic print les to the laser cutter. Go to https://fslaser.com/RetinaEngrave and choose

either the Windows print driver or the MAC/OS print driver.

Occasionally, RetinaEngrave 3.0 software will run an update. This is an
automatic process that can happen when you rst boot up the machine.
Typically updates are quick, however, there may be some occasions
where updates can take longer. You will know the machine is updating
when the interior lights of the Muse turn off. When this happens, DO
NOT turn off your machine. Allow the update to complete and the
machine lights will turn back on.

SECTION IV. TESTS & ADJUSTMENTS

It is important that your laser is tested and adjusted (if needed) for proper use before you start your

rst job. The following will be on our list of tests and adjustments:

1. Alignment Test

2. Mirror Alignment Procedure

3. Focusing

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

27

Alignment Test

The laser tube that came pre-installed in your Muse was carefully aligned in our facilities in Nevada.

When you rst turn on your machine, the mirror alignment should be perfect. It is possible, however,
that sometimes mirrors may come out alignment during shipping. Before running your rst job, you will

want to check and make sure the mirrors are properly aligned using this simple test. Once the mirror

alignment is conrmed, you are ready to use your laser cutter. If your mirrors are out of alignment, or

if you have installed a new laser tube, you must align the laser using the procedure provided. For this

alignment test we will test re the laser once in each corner of the machine to make sure the laser is

following the right path to the focus head, and ultimately to the cutting material.

1. Open the Safety Lid: You will need to access the interior of the machine.

2. Place Thermal Paper: Take a small piece of thermal paper (approx. 15 mm should be plenty)

and place it over the focus lens under Mirror #3.

3. Position Laser Head: Move the laser head into the upper left corner of the workspace.

4. Close Safety Lid: Safety measures should make it impossible to re the laser with the safety

lid open. Regardless, never attempt to re the laser with safety lid open.

5. Test Fire the Laser: Press the Fire Laser Icon Button on the touch screen.

ATTENTION! Find and push this icon on your Muse touch

screen to test re the laser.

6. Repeat Test Fire in Other Three Corners: Without removing the thermal tape, repeat

ring the laser once in each of the other corners of the machine (Upper Right, Lower Right, and

Lower Left).

7. Check Results: With the forth corner test re complete, open the lid and remove the thermal

tape. The four burn marks should overlap each other perfectly (see illustration). If they do not overlap
perfectly, you will need to align the mirrors.

will have two black dots from the test res in the top and bottom
positions. The red laser pointer is aligned with the invisible laser
pointer so gives you immediate feedback on the mirror adjustment.
By adjusting it into the middle of the two black dots, you are splitting
the error difference. Usually after 1 or 2 iterations, the black dots will
be exactly on top and this axis is aligned. The goal is to have the two
black dots overlap exactly.

The idea is that when the laser is not aligned, you

Mirror Alignment Procedure

The mirror alignment procedure goal is to rst align the visible red beam with the invisible CO2 laser
beam then use the red beam as the primary indicator for alignment. The idea is that when the laser

is not aligned, you will have two black dots from the test res in the top and bottom positions. The

red laser pointer is aligned with the invisible laser pointer to give you immediate feedback on the
mirror, the black dots will be exactly on top and this axis is aligned. The goal is to have the two black
dots overlap exactly. It is not necessary that the dots be in the center of the mirror but they should be
somewhere on the mirror.

Stage 1 Prep

Prepare your tools and workspace.

1. Safety First: Be aware of all safety procedures and precautions before continuing.

2. Power On Laser Cutter: The machine must be powered on to continue this procedure. Turn

on the machine by hitting the power switch. Allow the machine time to boot up the touch screen
operating system.

3. Unlock Driver Motor: The driver motor needs to be Unlocked to allow manual “jog” control.

On the touch screen, press the “Locked” icon to switch to “Unlocked” position. The button will now
display the “Unlocked” icon.

4. Gather Tools: A 2.5 mm hex wrench and a supply of thermal paper are required to perform the

mirror alignment procedure (if required).

PRO TIP! DO NOT over-tighten or over-loosen adjustment screws.

Tightening or loosening any of the three adjustment screws on the

mirrors or the red dot diode will move the position in a particular

direction depending on the positioning of the other screws. Some
experimenting is required to understand the relationship of each screw
and how adjusting one affects the red dot’s positioning. When adjusting
the screws, use the absolute minimum turn of the hex wrench to move
the red dot or the mirror into position.

Figure 4.5

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

31

Stage 2 Align Laser Output To Mirror #1

Conceptually, you will be aligning the invisible cutting beam with the visible red beam diode and
making sure they hit each mirror precisely. Once again, remember to check your mirror alignment
BEFORE starting this procedure as it is likely unnecessary if the laser tube was pre-installed in your Muse.

Figure 4.6

1. Open the Safety Lid: You will need to access the interior of the machine.

2. Place Thermal Paper: Take a small piece of thermal paper (approx. 15 mm should be plenty)

and place it rmly over Mirror #1.

3. Close Safety Lid: Safety measures should make it impossible to re the laser with the safety

lid open. Regardless, never attempt to re the laser with safety lid open.

4. Test Fire the Laser: Press the Fire Laser Icon Button on the touch screen. You will see a burn

mark on the thermal paper. It should hit the mirror in the middle.

5. Adjust Red Beam: Using your 2.5m hex wrench, make micro adjustments to the three

adjustment screws of the red beam diode, and position the red dot exactly over the burn mark.

Stage 3 Align Mirror #1 To Mirror #2

Because the 2nd mirror moves along with the X-gantry alignment must be checked between
mirrors #1 and #2.

1. Open Safety Lid: You will need to access the interior of the machine.

2. Place Thermal Paper: Take a small piece of thermal paper (approx. 15 mm should be plenty)

and place it rmly over Mirror #2.

3. Position X-Gantry “Far”: Jog or manually position the X-Gantry to the lowest position

(as shown in Figure 4.7).

Figure 4.8

4. Close Safety Lid: Safety measures should make it impossible to re the laser with the safety

lid open. Regardless, never attempt to re the laser with safety lid open.

5. Test Fire the Laser: Press the Fire Laser Icon Button on the touch screen. You will see a burn

mark on the thermal paper.

6. Adjust Red Beam. Using your 2.5m hex wrench, make micro adjustments to the three

adjustment screws of the red beam diode, and position the red dot exactly over the burn mark. Do not
worry if this places the red dot away from the center of the mirror, we will adjust to center in the next step.

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

33

7. Reposition the X-Gantry to “Close” Position: Now that we have a burn mark on our

thermal paper from a “far” ring of the laser, we want to re the laser from the closest position. Move
the X-Gantry to the upper most position in the machine and test re again.

Figure 4.9

8. Re-Position X-Gantry back to “Far”: Jog or manually position the X-Gantry to the far

position where you did the rst test re. (as shown in Figure 4.7).

9. Check Results: There should be two observable burn marks on the thermal paper. If they overlap

perfectly you can move on to the next mirror. If they are apart, adjust the three 2.5mm hex screws on
Mirror #1 (not the red beam diode) to move the second burn mark over the red beam.

10. Repeat Until Aligned: Check your results by repeating this process until the two burn marks

are both center and perfectly overlapping each other. Once aligned, you will repeat this procedure on
the next mirror.

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

Stage 4 Align Mirror #2 To Mirror #3

The 3rd mirror is mounted on the laser head assembly and slides along the X-gantry rail.

1. Open Safety Lid: You will need to access the interior of the machine.

2. Place Thermal Paper: Take a small piece of thermal paper (approx. 15 mm should be plenty)

and place it rmly over Mirror #3.

3. Position the Gantry Bar: Place the gantry bar in the center of the work bed, as shown in the

diagram below.

4. Position Laser Head “Far”: Jog or manually position the laser head to the far right (as shown

in diagram). This is the farthest position of the Mirror #3 from Mirror #2.

Figure 4.10

5. Close Safety Lid: Safety measures should make it impossible to re the laser with the safety lid

open. Regardless, never attempt to re the laser with safety lid open.

6. Test Fire the Laser: Press the Fire Laser Icon button on the touch screen. You may need to

re the laser twice to see the burn mark on the thermal paper.

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

35

7. Adjust Red Beam: Using your 2.5m hex wrench, make micro adjustments to the three

adjustment screws of the red beam diode, and position the red dot exactly over the burn mark.

8. Reposition the Laser Head to “Close” Position: Now that we have a burn mark on our

thermal paper from a “far” ring of the laser, we want to re the laser from the closest position. Move
the laser head to the far left of the machine and test re again.

Figure 4.11

9. Re-Position X-Gantry back to “Far”: Jog or manually position the laser head to the far

right where you did the rst test re.

10. Check Results: There should be two observable burn marks on the thermal paper. If they

overlap perfectly you can move on to the next mirror. If they are apart, adjust the three 2.5mm hex
screws on Mirror #2 (not the red beam diode) to move the burn mark over the red beam.

11. Repeat Until Aligned: Check your results by repeating this process until the two burn marks

are both center and perfectly overlapping each other.

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

Focusing

Focusing the Muse laser cutter is quick and easy. Your laser included a billet sized for the
included 2-inch focal length lens. Note that if your Muse has the autofocus feature, focusing is
automatic when the job is run.

1. Place Billet: After inserting your material into the workbed, place the billet on top of the material.

Note that if your material isn’t at, you may need to cut the material in stages, focusing each time to

each new material level.

2. Release Locking Mechanism: Release the locking mechanism on the focus head until the

air assist nozzle rests on top of the billet.

3. Retighten: Retighten the sliding head and remove the billet from the material.

General Functions

Vector Cutting

Vector cutting is the most common feature of a laser cutter. Vector cutting with a laser means “to cut a
line or shape”. When vector cutting, the laser follows the “vector lines” embedding in the vector image
to cut out the design. The laser starts at a designated location and follows the vector lines until the
shape is cut out. This process is highly accurate and requires no resolution adjustments because of

the properties of a vector image.

Vector Images

In Vector Cut mode, the software receives information from the print stream and interprets it as a

series of paths for the laser head to follow. For the print stream to have vector information, the le
being printed must be a vector image. Vector images are more exible than raster images. These
images are created using mathematical equations rather than pixel blocks. PDF’s work great as
vector les and are easy to resize without losing resolution. Company logos and branded graphics

are usually vector images.

Engraving

Engraving is the process by which complex designs are etched into a workpiece. Engraving
can range from a simple surface mark all the way through deep material removal. Engraving is
differentiated from cutting in that cutting is the process of burning a closed contour completely
through a workpiece. Engraving is also known as “Raster Engraving” or “Rastering”. For engraving,
a laser has two states: on and off. Every black pixel or “laser dot” is the result of the laser turning on

and ring at that location. This location is controlled by the input image, which can be thought of as a

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

62

“map” of on and off pixels. The laser res individual pulses corresponding to pixels in an image. When

the laser is operating in raster mode the head moves rapidly from left to right and slowly from top to
bottom, engraving your image pixel by pixel and line by line.

Images and Engraving

Engravable images use multiple colored pixels to form an image. JPEGs and PNGs are common
engraving image types. Most of the photos found on the Internet and photo prints are raster images.

Raster images are created using a xed number of colored pixels, so they can’t be dramatically
resized without distorting their resolution. When sized to ft a space they weren’t designed to,

the pixels become visibly grainy and the image becomes distorted. When this happens, altered
photos may appear pixelated or low resolution compared to the original source. Because of this,

it is important that you save raster les at precisely the dimensions needed to eliminate possible

resolution issues.

PDF Files

Engraving works with both vector and pixel-based source les, allowing you to engrave anything from
a simple block logo all the way to high-resolution photographs. A PDF le type is generally treated
as vector le, however, RetinaEngrave 3.0 can read PDF les as either a vector or an engraving le

when you import the image. This allows operator great freedom in converting any image le to a PDF.

Direct Printing PDF Files

The easiest way to import any le type to RetinaEngrave 3.0 is to “drag ‘n drop” it directly into the
workspace window. If there are ever any problems importing les in this manner, direct printing
a converted PDF le is the next method to try. Most design software have a simple method for

converting les to PDF and then directly printing them to the RetinaEngrave 3.0 software.

Designing in RetinaEngrave 3.0

RetinaEngrave 3.0 includes a robust set of design tools, allowing users to design in the software
without needing outside design software. Third party design software, however, is still an option for
RetinaEngrave 3.0 users. Just about any design software will work (You can choose the software you

are most comfortable with, as long as you can convert les to PDF (which most can). You can also

“direct print” to the software. Each operating system does this in a slightly different way, so check the
instructions for your particular program.

If you use third party design software and run into a problem with the print interface, we recommend

printing to the XPS Document Image Writer or saving as a PDF. PDF les save vector information and

are the best way to carry artwork from a non-compatible operating system (Mac or Linux) onto your
Windows PC.

Compatible design packages include: CorelDraw, Adobe Illustrator, Inkscape and Google’s free online

vector drawing application. Additionally, most CAD packages are able to output drawings in a vector
format for printing; Autodesk 123D is particularly interesting for its cost (free) and built-in 3D slicing
capabilities.

The RetinaEngrave 3.0 software works with your Muse to create a simple and intuitive set of

operations that is easy to learn and use. With experience, you will nd your Muse achieving amazing
results following this procedure. Use this Project Workow List for the “best practice” sequence for
any project and follow the step-by-step instructions from start to nish.

1. Create Design:

Create your design in the program of
your choice. Note: Files should be
created with laser cutting considered.

4. Place Material:

Place your material into the laser
bed workspace.

7. Adjust Object Properties:

Using the Properties Manager Window,
adjust your Vector or Raster settings for
your cut, mark or engraving.

2. Connect to Software:

Link your Muse to the software by typing
the IP address found on the Touch Screen
(Settings>Network>Copy IP) into your
browser (Google Chrome Suggested).

5. Focus:

Using the included focus billet, focus
the laser to the material (consult your
user manual). Note that if your Muse
has the autofocus feature, focusing is
automatic when the job is run.

Project Workow Checklist

Safety First

Before starting any project, be sure you are aware of all safety issues. Be sure you
read and understand all safety warnings presented in Section I: Safety First and
that all safety requirements are being upheld. This is a good time to check your

machine’s power connections and that the accessories are properly attached and are

operating normally.

1. Create Design

Typically, projects are created in design software and then imported to RetinaEngrave

3.0. Generally, a PDF le is optimal for most vector cuts, as PDF les are easy to

convert to and most design software has “convert to PDF” as a standard feature. For

rastering (engraving), a JPEG le is best as these are bitmap les perfect for pixel

based images. It is important to know, at this stage, if you intend to do a vector cut

or an engraving and choose the most appropriate le type (PDF or JPEG). This will

greatly aid the software to run the job smoothly and quickly. RetinaEngrave 3.0 includes
a robust set of design tools, allowing users to design in the software without needing
outside design software. Third party design software, however, is still an option for
RetinaEngrave 3.0 users. Just about any design software will work (You can choose the

software you are most comfortable with, as long as you can convert les to PDF (which

most can). You can also “direct print” to the software. Each operating system does this
in a slightly different way, so check the instructions for your particular computer..

2. Connect to Software RetinaEngrave 3.0

Follow the instructions presented in Section III: Installation & Assembly. As a recap, you

will turn on your computer and your Muse laser cutter and wait for both to nish their

boot cycle. Then, observe the connected network address on the lower left corner of

the Muse LCD. Copy this IP address into your computer’s browser navigation bar and

the program will appear, ready to use. For best results, we recommend using Google
Chrome as this is the most compatible with RetinaEngrave 3.0 technology. Note that
your PC and your Muse unit must be connected to the same network at all times during
normal operation.

3. Import Design

Import your designs by selecting the “Open File” icon, or by dragging and dropping your

le into the workspace. This software detects a wide variety of le types, however, for
vector cuts PDF les work best and are simple to convert on most design software. For
raster engraving, the JPEG le format is widely used and can easily be taken from a cell
phone photo or an image found online. It is important to know what les work best with

vector or raster images. A raster image is a pixel based image (bitmap) and works well

as a JPEG le. When you import a JPEG le, the software will automatically detect it
as a raster le and will setup the project accordingly by presented raster options in the

properties tab menu.

4. Place Material

At this stage you will place your material into the laser bed workspace. The material
can be placed anywhere within the workbed, however, we recommend placing material
close to center. Once the material is placed, close the lid. Your material is what you will
be cutting or engraving. Typical materials include wood, acrylic, cardboard, fabric, etc.

Note that is the user’s responsibility to know the components of any material used and

the limitations of utilizing that material (thickness, chemical residues, etc.) with a 45W
laser tube. Always check with the material manufacturer, or MSDSonline.com, if there
are any questions to its usage. We recommend using a Materials Log to keep track of
the different materials you use.

5. Focus

Follow the Focusing instructions given in Section IV: Tests & Adjustments. Just to recap,
you will place focusing billet on top of the material you wish to cut. Then align the laser
head to the focus billet and release the focus lens thumb screw and allow the laser head
to rest lightly on top of the focus billet. Finally, retighten the focus head and remove the
focus billet from the workspace. Note that if your Muse has the autofocus feature, focus­ing is automatic when the job is run.

6. Align Laser to Material

Alignment of the material ensures the design to be cut is contained within the material
in the workspace. This process also makes sure the design is aligned to the material so
the cut is positioned straight. Typically this can be done with a simple vision check while
“jogging the perimeter”.
By using the directional arrows on the touchscreen or the arrow keys on your computer,

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

66

move the laser dot to the top left corner of your material. When placing an engraving
image, leave at least ½” inch of space on the left and right side. When creating engrav­ings, you must compensate for the left and right overshooting of the laser head. Once
the material looks aligned, click the “Jog Perimeter” button. The laser head will automat­ically outline the material with the red beam diode. You can then adjust the material as
needed. Note the laser head will continue to outline the material until stopped manually
by clicking the “Run Perimeter” button a second time. See Positioning below for more
options.

7. Adjust Object Properties

It is again important to know if you intend to raster, vector cut or both. Once the le is

imported, and the image is clicked with your mouse, you will have access to the Prop­erties Tab. Click this tab and select the parameters for your cuts and/or engravings. For
details on setting these parameters, see below.

8. Run Job

Clicking the “Start Job/Play” button begins the laser cutting process. Before doing so,
double check your safety protocol and that your system accessories are connected

properly. Be sure to monitor the job while the laser is ring. If there is a problem, stop

the laser using one of the methods mentioned below.

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

67

Engraving

Engraving, also called Rastering, is the process of creating a surface image on material without cut­ting through the material entirely (aka vector cutting).

Setting Engraving Properties

Clicking an object (design image) in the workspace will allow you to access that object properties tab.
The software will identify if the object is a vector or an engravable object and present the appropriate
properties window. To show the properties of an engravable object, click the object.

Setting Resolution

The resolution of your engravings can be controlled by the DPI (Dots Per Inch). DPI options include
250, 500, and 1000. The more dots per inch, the higher precision and quality of your images, while a

lower DPI will process and engrave faster.

Remember that with a higher DPI (1000), the laser is in contact with the material for a longer period
of time and may result in deeper engravings than with a lower DPI (250). Speed and power should be

compensated for different DPI settings. The software’s default resolution is set to 250 DPI.

Setting Raster Power

The power settings determine the output of the laser tube. A 100% power setting will create
a deeper engraving while lower settings will create more surface level engravings.

Setting Raster Speed

Speed settings determine how quickly the laser head will move. For faster engravings,
100% is ideal. Lowering the speed will allow you to create deeper engravings, as it allows the laser
beam to be in contact with the material for a longer period of time.

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

68

Applying B/W Threshold

At this moment, the image is still displayed in black and white. The black and white raster feature is
great for tracing logos, text, or simple high contrast images that only appear in a single color. You can

adjust the threshold of what’s considered black, and what’s considered white by selecting your image

and clicking “Threshold”. This will bring up a B/W Threshold slide bar, from which you can adjust B/W
threshold to your liking.

3D Engraving Options

For images that have shadows and depth, it’s ideal to use 3D engraving. 3D engraving creates a

series of dots similar to newsprint. This effectively creates a grayscale that is ideal for photorealistic
engravings. To 3D egrave an object, click the 3D engraving button. You can then adjust the 3D
engraving with the Blur, Edge and Intensity slide bars.

69

Vector Cutting

Setting Vector Properties

When a PDF le is imported into RetinaEngrave 3.0, the program automatically detects it as both a
vector le and a raster le.

Vector Color

Tags allow you to create separate vector layers and keep track of them with a unique color. Each
color will match an object in the workscreen. You can set the order of operations by clicking on the
“three dots” and then dragging the layer up or down. Objects are then processed from top to bottom.

Setting Vector Power

Power will determine how much power the laser tube delivers. As with speed, power will vary
depending on the wattage of the laser tube and the material itself. You will need to experiment with

material testing to nd the right speed for your vector cuts.

Setting Vector Current

Vector current is a control unique to vector les. Vector current controls the pulse of the laser. 100%

will create constant power for smooth cutting, while lower percentages will add increasingly more off

time between pulses. As always, settings will vary with your tube wattage and type of material. It’s
best to test on an inconspicuous part of your material before creating your nal piece. Once optimal

results are discovered for speed, power and current, through material testing, record the settings for
each in a materials log.

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

70

Passes

This allows the operator to assign how many times the laser will complete a full cycle. Adding passes

creates deeper cuts. Note that if you delete a vector line (by clicking “-“), set passes to “0” rst.

Show All Parameters

This toggle switch displays or hides all possible vector tag as a series of color options. Often
when performing both vector cuts and raster engraving, it is a good idea to change the color of the
vector cut to something other than black. This will avoid the laser detecting the vector cut as part
of the raster.

Basic Vector Cutting Example

Vector Marking Example

We can outline (as opposed to ll) parts of the pattern for a second design option. Again, we will

instruct the laser using our vector properties In this design, the blue lines will not be cut through on
our material, but instead will be marked, as the red outline still cuts.

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

71

Combining Vector and Raster

Engravings can be combined with vector cuts to create a variety of outcomes. A simple example is to
engrave an image, and then cut the image out with a vector outline. In this case the laser will raster in

the black l and cut the red line.

Text Path Options

Attach Text to Path

This function allows the user to attach text to a shape and contour the text to that shape. As an ex­ample, user creates an ellipse design and a text element separately. With the mouse, drag a square
over both. By clicking Attach Text to Path, the text is merged with the ellipse and the text con­forms to the contour of the shape. The user can then drag the text element to the desired position,
using the mouse.

Detach Text from Path

This function reverses the Attach Text to Path option. Select the object and text with the mouse by
dragging a square to highlight both. Then, click Detach Text from Path. The shape and the text will
now be separated.

Convert to Path ( Shift+Ctrl+P)

Convert a non path to a layer path. If a layer is composed of elements that are treated like
paths, internally, or the layer is a Text object, the existing paths that make up the object are

simply extracted from the object as they are already dened. The result is a compound path

containing all of the separate paths. Any transform information from the original layer is not
retained in the individual paths. For all other types of layers a new path is created, preserving
any transforms. The user creates a text layer then converts to a path. Because the text was
comprised of more than one distinct element a compound path is created. The compound
path can then be split into separate paths for each distinct element in the text.

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

76

Convert to Raw Path

Convert a path or non path layer to a new path. This is similar to Convert to Path with some important
differences. With Convert to Raw Path new path objects are always created regardless of the type of
the original layer and transforms are preserved. The user creates a text layer then attaches it to an
ellipse path so that it follows the curvature of the ellipse, then converts the text to a raw path. The text

retains its curvature because the transforms of the separate text paths are preserved.

Creating Objects In Retinaengrave 3

The easiest way to create an object is to select a shape from the tools menu. For example, you want
to make a circle. Select the circle tool, then click and drag to create a circular shape. By holding shift
while dragging, you can constrain the proportions so that the circle is perfectly round. Design view
has hundreds of shapes that can be selected and manipulated to endless choices. Click the “Star”
icon to access shape library.

Creating Shapes

Click the Square Icon and then click and hold anywhere in the view window. By moving the mouse,
you can expand and manipulate the square you want to create. By clicking the drop down arrow next
to the Square Icon, you can choose other base shapes and expand them just like with a square. The
basic shape library includes line, rectangle, ellipse, polygon, triangle and star. You can modify any
shape by clicking on it and then adjusting the interface data appearing on the right side of the screen.

Each shape will have slightly different options as follows:

Line (L)

Creating and Manipulating Compound Shapes & Objects

Operators can combine and modify shapes and objects to create unique compound shapes and
objects with these functions (see also Modify):

Split Selection (Shift+Ctrl+G)

Split up a previously created compound shape or object that has been Unioned with other shapes.
Select the compound shape and choose Split Selection. The different objects are split back up into
individual layers that can be moved independently.

Create Compound Shape->Union

Combine multiple layers into a single compound layer. Union will create a compound shape contain­ing all of the selected layers, retaining their relative positions. Union together several different object
and create a compound shape so they can all be moved and manipulated as one. To reverse,, select
the compound shape and choose Split Selection. The different objects are split back up into individual
layers so you can move one of them independently.

Create Compound Shape->Intersection

Combine overlapping layers into a single compound layer. Intersection will create a compound shape
containing the areas where the selected layers overlap. Intersect together part of an ellipse and part
of a rectangle to create a new compound shape with curved and straight lines.

Create Compound Shape->Subtract

Remove and combine non-overlapping layers into a single compound layer. Subtract will create a
compound shape containing only the areas of the last selected layer where the other selected lay­ers do not overlap. For example, users can create an ellipse and subtract a rectangular area so the
ellipse can be placed over another layer and not obstruct part of it. Or use to make a design that is
made up of standard shapes by subtracting certain areas

Create Compound Shape->Difference

Combine non-overlapping layers into a single compound layer. Difference is the opposite of Inter­section. It will create a compound shape containing only the areas where the layers do not overlap.
For example, the user can create a large circle ellipse, then create a smaller circle ellipse. Place the
smaller circle ellipse over the large circle ellipse and center it. Select both layers and choose Differ­ence. A hole is created in the large circle ellipse and a donut design is formed.

Create Nested Compound

Combine compound shapes into a single compound shape. All of the selected compound shapes will
be nested within the compound shape that was selected last. For example, if user has created com­pound shapes and created the layout with the desired spacing but would like to move them all while
retaining the existing layout, creating a nested compound shape that includes them all works best.

Convert to Outline

Create an outline path of a specied size around an object. If the original object is not continuous,

such as a line, an outline is created around the line and the original line is replaced. If the original
object is continuous, such as a rectangle, an outline is created around the rectangle and the original
rectangle is preserved, resulting in a compound path with two rectangles. The user creates a curved
line then converts it to an outline of size 10. The result is a continuous curved polygon that looks like
a wet noodle.

Expand/Shrink

Scale an object up or down by a specied amount. The user creates an object and wants to grow it a
few pixels but trying to scale it with a selection box is too difcult. The user can expand the object by

specifying the exact amount.

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

Creating & Converting Vector Paths

A vector path indicates the line the laser moves along while cutting. For a simple line, the path is a
clear route from Point A to Point B. More complicated paths, and shapes, can be created using the
following options in the Modify drop-down window:

Vectorize Border

Use to create a vector path of the border of an object. For example, the user creates an object, such
as a rectangle, and wants to have a vector path of just the border of the triangle.

Vectorize Image

Use to create vector paths of each separate element in an image. For example, the user rst imports

an image. User then wants certain parts of the image to be vectors so they can be cut. User vectoriz­es the image and then moves some of the resulting vectors out of the image object. The vectors can
then be edited.

Join Paths (Ctrl+J)

Combine 2 or more selected paths into one compound path. The result is a single layer titled ‘Com­pound Path’. It does not connect them into one continuous path but rather a single object with breaks

between the individual paths that were joined. The user joins together multiple path objects so that
they can be transformed more easily and change their properties as a single object.

Split Paths (Shift+Ctrl+J)

Split a compound path into its original separate paths.The result is a path layer for each separate path
in the Compound path.

Simplify Path (Ctrl+Alt+S)

Simplify (and smooth) a path to varying degrees of tolerance. The user creates a freehand line or
compound curve but the resulting curve has some sharp turns and jagged edges. Next, select the

path and simplies it with a tolerance (start with 20%). The resulting path has fewer vertices and

smoother turns.

Connect Path Lines

Connect together the ends of 2 or more paths. The user vectorizes an image containing text. Due to
the low quality of the image some, of the text characters have breaks in their paths, so the user se­lects the lonely paths and uses the “Connect Paths Lines” feature to connect the paths.

Break Curve

Break apart a path at a specied node. The user creates a path but would like to separate it and add

space at certain vertices to add another artistic element in between. Or maybe to specify different
engraving parameters for different parts of the path. To do so, the user selects a node and chooses
“Break Curve”. The path is separated into two separate paths.

Reverse Order

Reverse the order of nodes in a path. When the user creates several paths and uses the “Con­nect Paths Lines” feature, they are connected but not at the desired ends. This is because the

paths are connected from the last node of one path to the rst node of the next. Undo the previous

action and chooses “Reverse Order” on one of the paths. Then connects the paths and they are
connected perfectly.

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

81

Positioning the Laser Head (Jog)

Operators will want to become accustomed to moving the laser head, in order to position the laser.
This can be done in one of two methods: manual and jog control. Manually moving the laser head
requires that the laser head be in the “Unlocked” position. To unlock the laser head, push the “Lock”
icon, on the touch screen, so that the icon has an open lock icon. The laser head can now be freely
moved to any position in the workspace by hand.

Jogging is when the operator uses the touch screen “jog” buttons, or Ctrl + Left Mouse Button within
the web application workspace, to move the laser head. To use the jog feature, the laser head must
be in the “Locked” position. To lock the laser head, push the “Lock” icon so that the icon has a closed
lock icon.

Positioning Material

Relative positioning is relative to the laser head. The red dot from the laser will be considered the top
left corner of an image. This makes positioning easier without the use of the Muse camera system.
Absolute positioning is the default mode and will directly translate the object’s location on the comput­er workspace to the respective location on the laser bed. Absolute positioning is ideal when using the
camera system.

You can switch from Relative Positioning to Absolute Positioning by going to Settings, within the Edit
drop-down options. Click Settings>Device. Next, choose Absolute Positioning or Relative Positioning
on the slide bar across from Laser Positioning. Click Save Changes when you are done.

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

82

Stopping the Laser

Once a project has begun, the laser will continue until the project is complete. If for any reason an
operator needs to stop the laser immediately, choose one of these options:

Figure 7.4

1. Open the Lid. The large workbed access lid is installed with a device that automatically (and in-

stantly) cuts off the laser if it is opened even slightly. This should be your rst method of stopping the

laser during an emergency. This is a safety feature of Muse and under no circumstances should this

safe lid auto-shutoff device be tampered with or removed. Doing so will void your machine’s warranty.

If the machine ever fails to shut off the laser when the safety lid is open, immediately unplug the ma­chine and contact customer service.

2. Touch Screen Pause Button. Top of Machine Pause Button. On the top of Muse machines there
is a button that can pause or stop the laser. Press once to pause the job. Press and hold to stop the
job. Once a job is stopped, starting again will start the project from the beginning.

3. E-Stop. On the touch screen, the top red bar is an “Emergency” stop button (E-Stop). Pushing this
bar will instantly cut power to the laser. Be aware this is still part of the touch screen and is fragile. Do
not slam this button.

4. Software Pause Button. In the software, on your computer, you can click the Pause Button (con­verted Play button when laser is running a job) to halt the laser. This may take a second to process,
so it is not recommended as a method of stopping the laser in an emergency.

5. Power Switch. At the back of the machine is the power on/off switch. Flipping this switch to the off
position instantly cuts power from the laser head (and the entire machine). Using this option will com­pletely cut power from the laser, the touch screen and all other Muse systems.

6. Unplug Power.

Camera: Capture Workspace

Use the onboard camera to capture your workspace to align your design.

Figure 7.18

1. Place material in center of laser bed.

2. Position the laser head above the material and use the focus billet to focus the cone above the
material surface. Ensure your material does not impede the movement of the laser head.

3. Initiate Camera Sequence - Press the Camera Icon on your RE2 software, or on the LCD touch
screen (for touch screen controls, see user manual) - Note that you 1) use the camera button, 2)
position the head, and 3) press the camera button again (this initiates sequence with no indication on
software). Follow the steps on the screen. Click “New Height Measurement”. The laser head will shift
back and measure the height of your material using the secondary red beam laser. You can repeat

this step several times for more accurate results. If results don’t improve, it may be that your material

is an uneven surface. Click Continue when focused.

4. After 9 photos are taken and stitched, your workspace should now represent your laser bed.
Position your design as needed (for help importing, see the Work-Flow Section), and adjust setting.

5. You are now ready to run your job! To double check a position on your workspace, CTRL-Click
anywhere on the work space to position the laser head there.

MASKING TAPE OVER WORK AREA

1. Choose your material, and prep. Flat objects work best, and we suggest you place masking tape

(paper tape) on the surface before marking with a pen (sharpie). Don’t allow the masking to tape to

overlay on the material when applying more than one strip.

2. Using a thick black marker or pen, draw on your material. Thick solid lines will be read the best. If

coloring in a space, ensure completely lled in.

3. Capture the workspace as shown in steps 3 & 4 in the “Capture Workspace” instructions.

4. Click on the “Vectorize” icon in the top menu bar (show with label). This will bring up a sub-menu.
Using your mouse, select the section you want to vectorize and press ok. You can repeat this step
as many times as you like. Place a white piece of paper behind your self-drawn design to help aid if
having trouble capturing the area you want to vectorize.

5. You now have Bitmap and Vector data for your object available.
They should appear in the Object Manager box. Delete data not needed. If just engraving, delete
vector data, if just cutting or marking, delete bitmap data.

6. You are now ready to run your job!

Maintaining Your Camera

Follow these simple tips to keep your camera clean and functioning at peak performance:
Just like with mirrors, you will need to clean the camera lens periodically. Use lens wipes to gently
clean the camera lens as needed.

Your camera system comes with a lens cap. When using the camera, remove this lens and keep in a
safe place. It is recommended that this cap be placed on the camera lens when the camera is
not in use.

Just like with mirror alignment, it may occasionally be necessary to correct the camera offset if the
camera is bumped or jostled. Follow the “Correcting Offset Camera Calibration” instructions below.

Camera: Height Calibration

Muse can detect the height of the material using the camera features. It is possible, however, that the
height calibration can be jarred out of alignment. To check height calibration, follow these instructions:

Height Calibration Test

1. Remove all objects from the interior workspace, including the honeycomb tray.

2. On the Touch Screen, click the camera icon. A popup screen will appear.

3. Click “New Height Measurement”. You will see a range of numbers appear. If the numbers are all

within 5/-5, the height calibration is acceptable. If the numbers are not within 5/-5, you will need to
adjust Height Calibration.

Height Calibration Procedure

1. On the Touch Screen, click the settings icon. Then click “Advanced”. Scroll to the bottom

of the page.

2. Click “Calibrate Height”. You will receive the following warning:

“Changing Height Calibration may invalidate custom Position Calibration data on the device.

It’s recommended to run this before calibrating camera position. If you already have position

calibration, this will be incorrect and must be recalibrated if height calibration is changed.”

3. Click “Conrm”. The following instructions will appear:
“This page lets you calibrate the height measurement laser for the camera. It’s recommended to
use a stack of 18 US Quarters and opaque tape to reduce the reectivity. However, if you don’t

have this, you can enter a custom calibration material thickness. All objects you use for height
calibration must be of identical height. Start with nothing in the laser bed for an initial measurement.
Then place three quarters, or your custom material, under the red laser. Click measure, then repeat
with more height each time until enough data has been collected.”
Again, it is required that the interior workspace be free of all objects, including the honeycomb tray.

4. Click “Measure”. The laser head will move to a xed position in the workspace. Place your three

stacked quarters under the red beam dot. Click Measure and repeat until 5 measurements are
taken. Note that the editable height default is 5.25 millimeters, the height of 3 US quarters. This
number can be adjusted for other coins or measuring blocks. After the 5 measurements, the Total
Height Measurement should be equal to or greater than 30 millimeters.
It is important to note that when a new height calibration is performed, the position calibration will
have to be re-calibrated, as well. This is not the case in reverse, however, and height calibration is
not necessary after position calibration

Technical Support is available from 8am to 5pm (PST) M - F at [email protected].

87

Camera: Position Calibration

This tool allows you to set image offsets at multiple points around the camera snapshot. Whenever

the snapshot function is used on materials of similar height, this calibration will be used to ne tune

the camera result. You may need to add additional calibration for materials of different heights.

1. On the Touch Screen, click the settings icon and then click “Advanced”. Scroll to the bottom of
the page and click “Calibrate Position”. Click “Conrm” and follow the on-screen instructions. They

will begin by telling you, “Height calibration and stitching need to be performed prior to proceeding.”

2. Click “Activate”. This will cause the laser head to move to a xed position in the workspace.

3. Place a sheet of thin material (a sheet of lined paper works well) under the red beam dot. It

will be helpful to mark the page with a “+” symbol to create an identiable target to align with.
Remember, your machine’s interior should be empty, including removing the honeycomb tray.

Click “Done”.

4. Click “Measure”. The laser head will move to a xed position in the workspace. Note, that when
you select “Measure” for the rst time, and the laser head moves to that xed location, it will set a

base height. You will also need to click “Done” between measurements. Place your three stacked
quarters under the red beam dot. Click Measure and repeat until 5 measurements are taken.
Note that the editable height default is 5.25 millimeters, the height of 3 US quarters. This number
can be adjusted for other coins or measuring blocks. After the 5 measurements, the Total Height
Measurement should be equal to or greater than 30 millimeters.

5. Click “View”. You will see the camera snapshot of the interior workbed. Click “Done”.

6. Click “Calibrate” and then click “Conrm”.

7. You will be taken to a new screen on the touch panel. At the top of the touch screen, the image

you took is displayed. You can zoom and move the crosshairs with your ngers. Pick a spot,
preferably your marked crosshairs, and manually maneuver the crosshairs over the mark you put
on the paper. Click “Set Calibration Point”. The red dot will move into position over that spot.

8. Next, look at the position of the red dot in the interior of the machine. If it is not directly over your
target, use the slow jog buttons to bring the red dot exactly aligned with the mark.

9. When you are satised they are aligned, click “Set Offset Point”.

10. You can back up or repeat the process, if desired. Click “Finish”.

11. Click “Conrm”.

Materials Testing

Muse is capable of cutting a wide range of materials. Common materials include wood, cardboard,
paper, fabric, acrylic, leather, and many more. Muse can also engrave on tile, stone, glass, and other
hard surfaces. Muse is not designed to cut metal of any type. If you have any questions whether a
material is suitable for a CO2 laser, contact the material manufacturer before use.

Figure 7.20

Dithered ExampleSample File

Vector Examples from Dark to Light

Using suitable materials will still have wide variance in power, current and speed settings depend­ing on the properties of that material, such as density and thickness. For example, wood can be soft
(pine) or hard (oak), depending on the source. Settings will also be determined by vector or raster

choices, depth of the cut and overall desired outcomes. This makes it difcult to provide operators

with exact settings for each type of material. Instead of giving inaccurate data, operators should be­come accustomed to material testing.

Full Spectrum Laser provides a free materials test template with suggested starting points in power
and speed settings. From there, you can experiment with your own materials testing. Once the per­fect settings are determined, we recommend recording those results in a Materials Log.
To access the material test templates, complete material testing instructions and a free materials log,

SECTION VIII. HARDWARE & MAINTENANCE

With a little care and maintenance, your Muse Laser Cutter will remain clean and continue to run at

top efciency for years to come. Be aware of all safety and maintenance issues with your machine

by following all the safety instructions in this manual.

Replacing the Laser Tube

This section provides procedures and a walkthrough to replace the laser tube on your Muse. Although
it should last for hundreds of projects, the laser tube is considered a consumable and will eventually
need to be replaced. Please carefully read all instructions before beginning the replacement
procedure as there are several critical steps which must be properly followed to avoid breaking the

laser tube. The included pictures show how to properly connect wires to the tube’s electrodes and

secure the connections.

REQUIRED PARTS AND TOOLS:

• 45W REPLACEMENT TUBE

• 2.5 MM HEX WRENCH

Replacing Laser Tube Steps

1. Power Off Machine: Power off and unplug your unit. Wait at least 1 hour for capacitors

to discharge.

2. Disconnect Water: Detach the water tubes from their connectors on the laser tube and drain

the water into a bucket.

3. Remove Water Tubes (Step One): Remove the two (2) water tubes from the bulkheads on

the back of the machine and carefully drain any water into a bucket. Use the small piece of tubing
that shipped with your laser to shunt the two water bulkheads in the back of the machine together.

4. Remove Water Tubes (Step Two): GENTLY remove the water tubes from the laser glass

bulkhead. Be careful not to let any excess water in the tubes spill onto the machine’s components.

5. Remove Tube Retainer Straps: Using a 2.5mm hex wrench (included with your purchase),

remove the four (4) M5 hex nuts from the two (2) tube retainer straps that hold the laser tube in the
rubber restraints.

6. Remove Old Laser Tube: Remove the tube from the rubber holders and carefully set it on

top of the machine. Be aware the laser tube is still connected to the machine’s wiring.

DO NOT pull on the wiring.

7. Remove Universal Laser Pin Connector: Carefully unscrew the universal laser pin

connector off the aperture end of the laser tube. Next unclip the connector on the other side of the
laser tube. You can now place the old laser tube aside for later disposal.

8. Reattach Universal Laser Pin Connector: Reverse step 8. Screw the universal laser pin

connector onto the aperture end of new laser tube and clip the connector back to the other end of the
laser tube.

9. Place New Laser Tube: Place the new tube into the rubber holders in the same orientation

as the old tube was in when it was removed (with the glass coils oriented to the RIGHT when
facing the machine).

10. Re-Attach Tube Retainer Straps. Gentle place the tube restraining straps back into

position over the rubber holders and secure the new laser tube in place.

11. Re-Thread Hex Nuts. CAREFULLY re-thread the M5 hex nuts onto the U-bolt posts and

make snug (but not yet tight) with the rear panel.

12. Re-Attach Water Tubes. Carefully re-attach the water tubes to the proper laser connection

bulkheads. Make sure that the water tube routing and locations match the original conguration.

We have now switched the old laser tube for the new laser tube.

You will need to retest the mirror alignment and possibly go through the
mirror alignment procedure again.

Belt Installation

The belts on your laser system are a consumable item and will eventually stretch beyond a usable
length or break. You can contact Full Spectrum Laser support for replacements.

SHOCK WARNING! The capacitors in the power supply

retain power even after turning the laser off. To ensure your
safety, turn off the laser, remove the power cord and wait at
least 1 hour before accessing the power supply.

WATER WARNING! You will be disconnecting the water

system and working with the laser upside down. Be sure the
machine is dry before proceeding with this process.

REQUIRED PARTS AND TOOLS:

2.5mm Hex key (included with accessories)

1. BELT INSTALLATION STEPS:

Power Off Machine. Power off and unplug your unit. Wait at least 1 hour for capacitors to discharge.

2. Disconnect Water: Detach the tubes from the rear connectors. Use the small piece of tubing

that shipped with your laser to shunt the two water bulkheads together.

3. Loosen Retaining Screws: Loosen or remove the M3 retaining screws and washers so that

the old belt can be removed and discarded.

4. Mount Belt: Run each end of the new belt through the mounting slot with the teeth on the inside

of the closed loop. The ends of the belt should protrude by approximately 3 teeth (6mm) through the

slot. Make sure that the belt forms a at, closed loop.

5. Tighten Retaining Screws: Tighten the M3 retaining screws to secure and retain the belt.

Starting the thread with your ngers can speed the process up.

6. Loosen the idler pulley mount: Once the belt has been installed on the riser, loop over the

drive and idler pulleys.

7. Tension the belt: Pull on the Y idler pulley mount with your hand. Moderate to strong force is

recommended. If the motors do not jog, verify that the motors are connected to the control card.

Maintenance: The Focus Lens will need, at minimum, weekly cleaning, depending on usage and
types of materials used. Only use optical grade lens wipes and gently wipe the surface of the lens
clean. Save the case the lens came for storage when switching to a different lens. With any lens,
always use the correct focus billet and air assist cone.

Lens Descriptions:

1.5” lens is appropriate for extra ne engravings such as fonts below 6pts.

2.0” lens* has a good combination of ne engraving and thin cutting for fonts between 6pts and 8pts.

2.5” lens is appropriate for cutting up to ¼” of material and engraving detail to around 8pts.

5.0” lens is for cutting thick foam. it is also a good lens for engraving into deep bowls, when more

room is needed.

*This is the included lens for Muse

General Maintenance

Before Every Job:

- Always be sure your water, air, exhaust, and power systems are properly assembled and operating normally.

- Be sure that the machine and workspace are clutter-free.

- Be aware of any material warnings and that you are working in a well-ventilated workspace.

- Check that your re extinguisher is up to regulation and is easily accessible.

- Always follow all safety protocol.

Weekly

- Wipe down the walls the machine with a clean rag.

- Use optical grade lens wipes to clean both sides of the beam combiner, all mirror surfaces, the focus
lens, and the tube aperture. Optic surfaces may need to cleaned more often if cutting materials produce
excessive residue (possibly daily).

- Clean fallen debris from the catch tray of the machine. Less excess material will reduce re risk, and

provide for better exhausting.

- Always keep rails, motors and moving parts free from excess material as it can obscure movement and
cause damage.

Monthly

- Check rail lubrication. When the laser arrives, you should be able to visibly see the lubricant on the X
and Y rails. These rails will not need to be re-lubricated often, but check monthly to be sure that the rails

are properly lubricated and aren’t grinding or catching.

- Check your fume extractor lters. Depending on your output and the materials being cut, your fume
extractor lters may need to be replaced as often as every month (or sooner).

Quarterly

- Change water in cooling system. This will keep your tube safe from unwanted debris, mold or evaporation.

- A chiller system is enclosed and will stay relatively clean and undisturbed, but it is good practice to check
and change the water as needed.

- Check for wear on belts. Well lubricated belts should last, however, eventually they may wear and crack
and need replacement.

Assembly

1. Safety First: Before starting this procedure, turn off your muse and unplug it from all power
sources. We recommend to wait at least 20 minutes to ensure no residual electricity remains.

2. Remove Existing Exhaust Plate: Using the provided 2.5mm hex key, remove the four (4) screws
from the existing exhaust plate and set them aside in a secure location. Then remove the existing
exhaust plate. You will no longer need the old exhaust plate, however, hold on to two (2) of the screws
to secure the new adapter plate, in the next step.

3. Attach Adapter Plate: Using the 2.5mm hex key and the two (2) screws saved from removing the
exhaust plate (see step 2), attach the adapter plate on the back of your Muse, where the old exhaust
plate was.

4. Attach Exhaust Fan: Using the 5.5/7mm wrench, attach the exhaust fan to the adaptor plate with
the two (2) M3 Nuts. Note that the arrow on the fan needs to be pointing out the case.

5. Connect Exhaust Fan to Cowling: Carefully connect exhaust fan connector to exhaust fan

cowling connector. Do not force the connection. The connectors only t one way and should gently

slide together and secure.

6. Attach Fan Cowling to Adapter Plate: Carefully slide the fan cowling onto the adapter plate by
aligning it straight and then pushing forward. Hold the cowling steady and secure with the four (4)
acorn nuts. Tighten until secure using your ngers or the provided 5.5/7mm wrench.

IMPORTANT: Once cowling is attached, make sure the wires are not interfering with the fan. Inspect
visually and then spin the fan by hand from the inside of the Muse to ensure it is unobstructed.

7. Connect Air Assist Hose to Coolbox: Disconnect the air assist hose from your existing air pump.
Do not disconnect the other end of the air assist hole from your Muse. Next, attach the air assist hose
to the “Air Out” port on your coolbox.

8. Connect Exhaust Fan to Coolbox: Using the provided 2-Pin Cable attach one end to the slot on
the fan cowling and the other to the back of the coolbox, in the slot labeled “Exhaust Control”. Once
each is snug in the slot, gently turn the metal rings on each end of the connector and tighten.

9. Connect Side Panel to Coolbox: Using the provided 4-Pin Cable attach one end to the slot on the
new side panel and the other to the back of the coolbox, in the slot labeled “Machine Control”. Once
each is snug in the slot, gently turn the metal rings on each end of the connector and tighten.

10. Connect Water Tubing to Coolbox. WARNING: The water tubes may contain water if you have
used the machine. Have a towel ready to catch any excess water that may pour out of your tubing
and avoid spilling on electronic components or sources of electricity. Detach the “Water In” water
tube from the existing water pump and securely attach it to the “Water Out” slot on the back of the
coolbox. Next, take the unconnected “Water Out” tube (the end that went to your water bucket) and
securely attach it to the “Water In” slot on the back of your Muse. This will create the proper circulation
of water through the laser tube and back to the coolbox.

11. Connect Ducting to Exhaust Port: Place your 4” ducting over the Exhaust Port located at the
back of the machine and hold. Secure with 4” ducting clamp or industrial ducting tape.

12. Connect Power Cord: Insert the Non-Outlet end of the power cord to the back of the coolbox, in
the AC power slot just above the power switch. Next, plug the other end into an appropriate outlet. DO
NOT plug the Coolbox into the slots in the back of your Muse.

Using Your Coolbox

1. Add Distilled Water: Unscrew water cap. Fill tank with distilled water (approx. 1250 ml). Put cap
back on and tighten.

2. Power On Coolbox: Flip the red power switch to the “On” position. Remember to always run your
coolbox when the laser is operating

Appendix B: Rotary Attachment Installation

The Full Spectrum Laser Hobby Advanced Rotary Attachment is an accessory to the Muse Laser
System and is not included with the base purchase. You can order the rotary attachment from the Full
Spectrum Laser website at http://fslaser.com/Products/LaserAccessories. The rotary attachment is
capable of engraving on objects from 0.25in diameter.

ROTARY ATTACHMENT INSTALLATION

The rotary attachment is a friction-wheel type—objects rest on two driven and two idling wheels and
are turned to engrave an image onto the surface of a cylindrical object. The rotary attachment works
by translating Y motion along a cylindrical surface.

INSTALLATION STEPS

1. Power Off Machine: Power off and unplug your unit. Wait at least 1 hour for

capacitors to discharge.

2. Position Rotary: Place the rotary attachment into your laser’s work area.

3. Connect Rotary:

the rotary attachment motor keeping the same orientation as in the diagram below.

4. Switch to Rotary Mode in Software: The nal step is to inform the software you are using the

rotary. To do this, Click the Edit button, then click Settings. This will bring up the Settings menus. Click
Device. Under device options there is a slide bar across from “Rotary Mode”. Click the slide bar and
make the bar blue. Next, below Rotary Mode, there is a bar for Laser Positioning. The rotary requires
this to be set to Relative Positioning. Finally, click Save Changes at the bottom of the screen. The
rotary is now ready for use.
You can switch from Relative Positioning to Absolute Positioning by going to Settings, within the Edit
drop-down options. Click Settings>Device. Next, choose Absolute Positioning or Relative Positioning
on the slide bar across from Laser Positioning. Click Save Changes when you are done

Find the rotary connector inside the machine under the LCD display. Connect

Figure 8.3

PRO TIP! Once you have connected your rotary attachment,

you can activate your laser and move the rotary attachment and
laser head into a position to engrave on your workpiece. The
red dot should be in the same vertical (X-Z) plane as the center
axis of the workpiece.

Appendix C: Using the Rotary Attachment

The rotary attachment is designed to be used within the laser case, however its maximum engraving

diameter can be increased by modifying your laser system’s bottom panel. Please be aware that
any system modications must be performed by an authorized technician and in accordance with all

applicable state and federal laws.

ALIGNING YOUR ROTARY ATTACHMENT

The best way to align your rotary attachment with the laser head is to build a jig that uses the frame as
a reference. This is a very quick process.

1. Starting Position: Focus the laser head onto the rear frame of the rotary attachment on the far

left when facing the machine from the front.

2. Slide: With the red dot visible, slowly slide the laser head to the right.

3. Align: Adjust the positioning of the rotary until the red dot tracks back and forth evenly down the

center. Note that the rotary is not assembled to the body of the machine but is freestanding. You may
need to re-align your rotary each time you use it.

Figure 8.4

PRO TIP! Rotary engraving is best performed along the

topmost area of the project. It is crucial that the rotary be

level. Use a small carpenter’s level to be sure your rotary is
at within the interior of the laser cutter.
