2.0 Overview
2.4 How It Works
2.4.1 3D Printing
When Robox® is using the 3D printer head, it uses a technology known as Fused
Filament Fabrication (FFF). This works in a similar way to a hot-melt glue gun using plastic filament instead of glue sticks.
The feedstock for the print head is 1.75mm thermoplastic filament which is
supplied on a reel for installing into the printer. This is then fed to the head via a
Bowden tube using the extruder, which contains two contra-rotating feedwheels
to grab hold of the filament, and push it along the tube to the head.
When the filament reaches the head, it is extruded out of a hot nozzle, which
melts the plastic and can control the diameter of the extrudate by using two
dierent size nozzles. This twin nozzle arrangement allows for highly detailed
outer surfaces of the print (those that are visible), alongside the larger nozzle
which is used for filling in parts quickly.
The printer head is mounted to a quick-release carriage, known as HeadLock™
which is constrained by a Cartesian axis system, allowing the head to move in 3
dimensions.
The included AutoMaker™ soware translates your 3D design files (in .stl or .obj
format) into machine coordinates that Robox® can understand. It does this by
‘slicing’ the 3D model into it’s individual layers, and then sending each slice (or
layer) to the printer, one at a time.
To produce a part, the molten plastic is laid down one layer at a time, and the
head moves up by a small amount (as little as 0.02mm!) at the end of each layer.
This allows fully-solid plastic parts to be constructed, with the quality of the
surface finish being determined by the height of the individual layers (quality
setting).
Robox® SmartReels are available in a variety of materials, finishes and colours
and they are automatically recognised by the machine, setting all of the
appropriate parameters for you. All you need to do is pick one, choose what
quality you’d like your model and hit print!

4.1 Loading Filament
This section explains how to load your chosen 3D printing plastic filament
into Robox® ready to produce your first print! It is designed to be a very simple
process with most functions taking place automatically.
4.1.1 Preparing the Filament
Before attempting to load filament, it is advisable to cut the end at a shallow
angle using a knife or sharp scissors to produce a sharp tip as shown below. This
will allow the filament to enter the extruder and melt chamber more easily.
4.1.2 Feeding to the Head
Simply feed the end of the filament into one of the two extruder entrances
located in the bottom-le of the reel storage dock. If only one extruder is installed
in your machine, use the top path marked ‘1’. It is much easier to perform this
operation BEFORE installing the reel into the dock.
Once the filament reaches the extruder, you will hear the motor start; at this point
continue to feed in until you feel the filament has been grabbed. Robox® will then
automatically feed the material all the way to the head.

4.2 Unloading Filament
This section explains how to remove a reel of filament for storage or to change to
a dierent colour/material. This process has also been designed to be as simple
as possible, and can even be undertaken mid-print!
4.2.1 Pause / Resume / Eject Button
There is a button in the centre of the reel when installed which has three
functions - Pause, Resume and Eject. To pause the print, simply press this button
once, and to resume press the button again.
To eject filament, you must hold down this button for 3 seconds, at which point
you should hear the extruder motor start and the filament will start to reel back
onto the spool.
www.cel-robox.com

4.0 Using Robox
4.2.2 Removing The Reel
Once the extruder motor has stopped, your filament has been fully ejected. Press
the two metal buttons on the top and bottom of the reel hub and pull the reel
away from the machine. Coil any extra material onto the reel - the loose end can
easily be held by weaving in and out of the holes in the rim.

4.3 Filament Storage
Most plastics, including ABS and PLA are ‘hygroscopic’ in nature i.e. they absorb
water from the surrounding environment. This oen has desirable eects, for
example in the case of Nylon, higher water content results in higher part strength.
However, when using plastic filament as a feedstock for 3D printing, higher water
content has a negative eect. As the plastic melts in the head, the water content
evaporates and turns into steam. As the molten plastic leaves the nozzle, the
reduction in pressure creates bubbles in the extrudate. This ‘outgassing’ of steam
can ruin the quality of the print, leaving pock marks in the surface finish where
the bubbles have popped.
It is therefore essential to store your filament somewhere very dry when your
Robox® is not in use for any extended period of time. SmartReels are packaged in
an airtight sealable bag with a sachet of silicagel, which should remove any water
from the bag and keep your filament dry. We recommend returning your filament
to its bag aer each print to ensure it stays print fresh!
If you already have ‘wet’ filament, it can be dried using an o-the-shelf dessicant
or dehumidifier - look out for colour indicating silicagel which changes from
orange to green to indicate it has become saturated. It can then be dried in a
conventional oven to ‘recharge’ it - refer to it’s accompanying instructions.

Head Change
4.4 The HeadLock™ System
This section explains how to change the head on Robox® allowing you to change
its functionality. The base model comes supplied with the Dual Nozzle, Single
Material head for FFF 3D printing. All future head designs will make use of the
same interface, and the HeadLock™ system has been designed to make head
replacement quick and easy. A microchip in each head also allows AutoMaker™
to automatically identify what head is installed, and set itself up appropriately.
4.4.1 Removing a Head
To remove the head, click the ‘Head Change’ button in AutoMaker™ and you will
see the head move into position to allow easy access to the locking screw.
Turn o your Robox® using the power switch on the back or at the wall
outlet.
This screw is located behind the head on the back of the X Carriage and is used
to firmly constrain and fix the head to the carriage. Reach over the top of the
head and rotate this screw counterclockwise to unlock, as shown in the diagram
below:
Continue to rotate the locking wheel until you feel it turning freely.
www.cel-robox.com

4.0 Using Robox
Once unscrewed, pull down the head as shown in the diagram below - you will
hear a ‘snap’ as the head disconnects.
4.4.2 Installing a Head
To install a new head into Robox®, the process is essentially the same in reverse.
First, push the bottom of the head into the carriage until you hear/feel a ‘snap’
- this signifies the head is correctly aligned and located, then simply tighten the
locking wheel until fully tight. You should see the head recognised in AutoMaker™
when you switch the power back on.

AutoMaker™ will then begin to slice your 3D model and transfer to your Robox®
ready for printing. Due to the unstable nature of printing ‘by wire’ - sending data
over USB during a print, Robox® incorporates onboard flash storage for storing
print jobs once production has started. This means that when the print job
has been fully transferred, you can disconnect from the USB, and Robox® will
continue to print unattached.

• Brim Width
‘Brim’ is a term applied to FFF (Fused Filament Fabrication) which describes
a large flat area which is printed around the part to help with bed adhesion
and warping. It can be easily trimmed o aer printing, but may greatly
increase the success rate of prints with a small surface area at the base. This
number specifies the number of loops (and therefore the width) of the brim.

• Material Name
This field can be used to name the material profile - this will be displayed on
the Status page when the reel is installed in the dock.
• Material Type
Pick the material type here from the list of available options, or type the
name of the material yourself.
• Material Colour
Pick the material colour here, or choose custom to define your own colour.
• Filament Diameter (mm)
Enter the diameter of your filament in mm - it is recommended to use digital
calipers / micrometer to obtain an accurate value for this field.
• Filament Multiplier
This value is used to compensate for the ‘squishyness’ of your material. As
filament passes through the extruder, it can be compressed by the feed
wheels causing to change shape slightly. This can aect the amount of
material that is fed to the head - the harder the material, the closer this value
should be to 1.
• Feed Rate Multiplier
This multiplier allows you to finely tune the extrusion rate of the material - it
can be adjusted during a print to obtain the optimum extrudate profile.
Increasing the value above 1 will cause more material to be extruded and
vice versa - 2 would be equivalent to 200% material flow. It varies the amount
of plastic proportionally and should be changed in very small steps (e.g. +/-
0.05) as the eects are very visible.
• Bed Temperature (°C)
This value sets the temperature of the print bed surface during a print. A
heated bed will help to reduce warping and improve adhesion of a wide
range of materials. ABS requires a bed temperature of approximately 110°C
for good adhesion, whereas PLA only requires 60-80°C.
• Bed Temperature (1
This value sets the temperature of the print bed surface when printing the
very first layer of the object. This value is oen set higher to ensure good
adhesion when starting a print, however the temperature can be lower for
the remainder of the print, or it may cause the object to ‘sag’ at its base.

• Nozzle Temperature (°C)
This value sets the temperature of the nozzle used for printing the material.
Dierent thermoplastics require dierent nozzle temperatures due to their
diering melting points (or more accurately, glass transition temperatures).
For example, most ABS requires a nozzle temperature of 240°C, whereas PLA
only requires 200°C to print successfully.
• Nozzle Temperature (1
This value sets the temperature of the nozzle when printing the very first layer
of the object. This value is oen set higher to ensure good adhesion when
starting a print, however the temperature can be lower for the remainder of
the print.
• Ambient Temperature (°C)
This value sets the temperature of the enclosed build area. By maintaining
the temperature of the environment, it is possible to keep the printed object
warm, reducing its tendency to shrink and warp. The best results will be
obtained by maintaining the temperature of the object until the end of
the print when the whole object can be cooled simultaneously. Warp is
introduced when the part is cooling unevenly, with areas that are shrinking
exerting forces on areas that are still warm and so.

• Perimeter Print Speed (mm/s)
This parameter sets the speed at which perimeters (the walls of the object)
are printed in millimetres per second.
• Small Perimeter Print Speed (mm/s)
This parameter sets the speed at which small perimeters (meant for holes,
islands and fine details) are printed in millimetres per second. A slower speed
than ‘Perimeter Print Speed’ is recommended for improved quality of small
details.
• External Perimeter Print Speed (mm/s)
This parameter sets the speed at which external perimeters (the outside
surface of the object) are printed in millimetres per second.
• Infill Print Speed (mm/s)
This parameter sets the speed at which infill (the internal filling of the object)
is printed in millimetres per second. This value should be as fast as you can
go without compromising the integrity of the fill structure. Faster extrusions
can break and result in weak spots of the object.
• Solid Infill Print Speed (mm/s)
This parameter sets the speed at which solid infill (the bottom of the object
and any other solid layers) are printed in millimetres per second.
• Top Solid Infill Speed (mm/s)
This parameter sets the speed at which top solid infill (the top surface of the
object) is printed in millimetres per second. This is usually slower to allow
time for the extrusion to cleanly cover the previous top layers and result in a
tidy top surface. The last few layers should have bridged the infill structure
nicely, preparing the way for a neat finish.
• Support Material Print Speed (mm/s)

• Bridges Print Speed (mm/s)
This parameter sets the speed at which bridges (unsupported layers between
two existing surfaces) are printed in millimetres per second. The ability to
span unsupported areas depends on the material and cooling. Going too
slow will result in sagging, too fast will result in broken strands. Generally
bridging runs slower than perimeters.
• Gap Fill Print Speed (mm/s)
This parameter sets the speed at which small gaps are printed in millimetres
per second. Filling in small gaps results in the head quickly oscillating and
the resulting shaking and resonance could have a detrimental aect on the
print. A smaller value here can guard against this. A setting of zero disables
gap filling completely.

This setting is used to enable or disable automatic cooling for 3D prints.
AutoMaker™ uses one of two methods to control cooling - it can either
increase the fan speed or slow down the time to print a layer. The choice of
which method is used is controlled by ‘Enable Fan if Layer Time <’ and ‘Go
Slow if Layer Time <’.
• Minimum Fan Speed (%)
This sets the minimum fan head speed as a percentage of full power.
• Maximum Fan Speed (%)
This sets the maximum fan head speed as a percentage of full power.
• Bridges Fan Speed (%)
This sets the fan speed which is used when printing bridges as a percentage
of full power.
• Disable Fan for First n Layers
This disables the head fan when printing the first n layers, this can help with
adhering the first layer to the bed. It is recommended to leave it o for the
first 1 or 2 layers.
• Enable Fan if Layer Time < (seconds)
This will increase the fan speed to maximum if the layer time takes less than
the specified value in seconds.
• Go Slow if Layer Time < (seconds)
This will slow down the print speed if the layer time takes less than the

6.1 Removing Breakaway Support Material
Breakaway Support Material is produced using the same material as the desired
part, and therefore Robox® only requires a single material head and one reel
installed. A lattice of material is extruded at the same time as the rest of the part
which is used to ‘prop up’ the printing of unsupported areas (overhangs, bridges
etc.).
Once your object has finished printing, you will need to remove the support
material to reveal the finished part. There are many ways to acheive this, but it
usually requires a combination of brute force and delicate trimming. To help you,
we’ve provided a set of 4 cleanup tools in the accessories box:
There are a range of shapes which should be very helpful when cleaning up small
blemishes on the surface of the part and for cutting away support in diicult to
reach areas.
Some material can easily be broken away from the part, or a pair of needlenose pliers can be useful for crushing/breaking support and then used to pull
the material away. It can be quite a frustrating task, but you will soon discover
methods that work, and those that don’t - once you’ve found a good one it’s
great to see a perfect model emerge from a lump of (seemingly) random plastic.
• WARNING! The set of cleanup tools are very sharp - please take extreme
caution when using them and always cut away from your body. Not
suitable for use by children except under adult supervision.
• WEAR GLASSES Always use safety glasses/goggles when removing support
material, especially PLA as the fragments can be very sharp and could
damage the eyes.
• WEAR GLOVES Always wear gloves when removing support material as the
tools and removed material can be very sharp.

6.2 Removing Soluble Support Material
If your Robox® has a dual material head and second reel holder (RBX01-DM) then
you can make use of Soluble Support Material for supporting your models. Your
part is le with no visible blemishes and a smooth surface. The larger areas can
be removed by hand to speed up the process, but it is designed to be a largely
hands-o process. There are currently 3 possible material choices:
6.2.1 Polyvinyl Alcohol (PVOH)
This is a water soluble support material which is compatible with PLA and ABS
as a build material. It can be dissolved in cold water, but the process can be
accelerated using ultrasonic vibration and/or slightly elevated temperature.
6.2.2 High Impact Polystyrene (HIPS)
This material is only for use with ABS build material. It can be dissolved in
Limonene, which will dissolve the support but leave the ABS intact. The
dissolving process can be accelerated using ultrasonic vibration and/or slightly
elevated temperature.
6.2.3 Polylactic Acid (PLA)
PLA can be used as a support material for ABS parts - it is soened in hot water,
allowing for manual removal or it can be dissolved using a hot caustic soda
solution and accelerated using ultrasonic vibration.
www.cel-robox.com
8383
6.0 Finishing Parts
6.3 Vapour Finishing
This is a process which can be used to improve the appearance of the ‘stair
stepping’ eect (visible layers in the print). It works by condensing a thin film of
solvent on the surface of the part which partially melts the surface, allowing liquid
plastic to flow into the gaps between layers. The solvent used is dependent on
the surface to be smoothed, for example Acetone or MEK is used to vapour finish
ABS and Ethyl Acetate (sometimes sold as MEK substitute) can be used for PLA/
PET.
The solvent is heated to vapourisation temperature in a closed chamber
(~60°C for Acetone, ~75°C for Ethyl Acetate), then the part is introduced to this
atmosphere. Because the part is cooler than the surrounding vapour, the solvent
condenses evenly on the surface.
The amount of smoothing is controlled by the quantity of solvent and the
exposure time. If the part is exposed for too long, the surface can melt too much,
resulting in a loss of detail as small features begin to melt away.
It is possible to achieve a high gloss finish with no hand finishing using this
method. More information can be found online by searching for ‘vapour
polishing’, ‘vapour smoothing’ or ‘vapour finishing’.
• WARNING! Use extreme caution when handling solvents - refer to the label.
Many can be extremely flammable and can also cause drowsiness, eye and
respiratory irritation.

7.0 Calibration and Maintenance
7.1 Calibration
Occasionally Robox® will need to be calibrated to ensure the quality of printed
output. This is particularly important on first use or if the unit has been moved or
subjected to large shocks or vibration.
The majority of the setup of the machine is performed automatically during
the print process, however there are some parameters which vary between
machines/heads. These calibrated parameters are stored in the printhead and
should only need to be performed once or twice during their lifetime.
All calibration procedures are performed with AutoMaker™, and therefore your
Robox® must be connected to your computer with the USB cable. All calibration
and maintenance procedures can be accessed through the Advanced Settings
Tray on the Status screen.
• This area of AutoMaker™ is still in development - please check our website
for an updated version of the user manual if you require further information.

If you are having any problems with your print adhering to the bed, before trying
anything else, clean the bed using the supplied bed cleaning wipes. These
are impregnated with Isopropyl Alcohol (70%) which should remove any oily
residues which may be aecting the PEI. No other bed preparation should be
required to print with a large range of materials.

• NEVER clean the PEI print bed using Acetone or other harsh solvents/
chemicals - they are unlikely to improve adhesion, and will damage the bed
surface.

7.2.7 Build Chamber
Always try to ensure that the build chamber remains clear of debris, whether it
is mis-extruded filament or otherwise. This debris can get trapped in the various
moving parts of the machine and aect homing accuracy and motion, possibly
causing damage to Robox®.

7.0 Calibration and Maintenance
Any debris which is fallen through into the area below the bed can be cleaned
out by removing the front tray cover (slide firmly towards you) and then tipping
forward - a gentle shake should clear it out.
To replace the cover, ensure all clips on the sides of the front tray cover are
aligned with their mating features, and then push towards the back of Robox® to
‘snap’ into place.
7.2.8 Extruder
To be completed.
7.2.9 Lubrication
In order to keep your Robox® in top working condition, it is essential that you
keep all of the motion system lubricated - including the Z drive screws and linear
rails. This must be performed at regular intervals (approximately 200 hours of
printing). There is a bottle of axis lubricant included in the accessories box which
shipped with your Robox® - if this is not available, a light mineral oil would be
suitable e.g. sewing machine oil.
To complete this process follow the instructions below:
1. Home all axes using AutoMaker™.
2. Apply a thin smear of lubricant to the X-Rails

7.3 Troubleshooting
This section of the user manual is intended to help you diagnose and fix a wide
range of issues you could be experiencing with your Robox®.
Problem / Symptoms Solution(s)
Hardware - My Robox® won’t turn
on - is it dead!?
Hardware - I’m having trouble
getting the first layer of my print to
stick to the print bed.
Robox® will ‘play dead’ unless the
AutoMaker™ soware is running. Also ensure
the USB cable is connected, the power
switch on the rear of the unit is in the ‘On’
position, and the fuse in the plug is intact. If
you are still experiencing problems, please
contact CEL support.
There are a number of possible causes and
solutions:
1. Try cleaning your print bed using the
supplied bed cleaning wipes, or a clean cloth
soaked in Isopropyl Alcohol.
2. There could be a problem with the
automatic bed-levelling system - try running
the ‘Level Gantry’ calibration.
Hardware - My motors/bearings are
making a ‘grinding’ sound as the
print head moves around the build
area.
Hardware - I can’t unload my
filament
Hardware - I’m having trouble
loading a new reel of filament
www.cel-robox.com
It sounds like you need to perform some
maintenance, try lubricating the drive
screws and motion rails using the supplied
Axis Lubricant. See section X.X for more
information on maintenance procedures.

Hardware - I can’t get material to
extrude
Hardware - There’s a clicking sound
coming from my extruder during
printing.
Hardware - I can’t get material to
extrude
Printing - My print is stuck to the
bed. Help!
To be completed.
1. Verify the material is coming of the reel
easily and isn’t tangled.
2. Your extruder may require cleaning - this is
a simple procedure that can be performed
using a household vacuum cleaner. See
section X.X for further information.
3. Your printhead could be blocked. Try
running the purge procedure to clean
out any degraded plastic that may have
accumulated in the melt chamber.
If these procedures have no eect, please
contact CEL support.

7.0 Calibration and Maintenance
Soware - My antivirus soware
has detected a problem with
AutoMaker™.
This is likely a ‘false positive’ based on
‘reputation’. Many antivirus packages use a
reputation based system to determine the
safety of soware based on the number
of instances that have been seen by other
users. As AutoMaker™ is brand new sofware
it may trigger these checks until it has been
installed by more users worldwide. It can
usually be rectified by restoring the file from
quarantine. If you have any further questions
please contact CEL support.

8.1 GCode Commands
This section contains a full list of GCode G and M commands which are
applicable to Robox®.
Coordinated Rapid Movement [X Y Z E D B]
G0
G1
G4
G28
G36
G37
G38
G39
G90
G91
E = Extruder 1 (mm³), D = Extruder 2 (mm³), B= Nozzle Motor (0=closed, 1=fully open) This will
move the head to an absolute location at maximum axis speed. e.g. G0 X100 Y100 (move to
100,100)
Coordinated Movement [X Y Z E D B] F
E = Extruder 1 (mm³), D = Extruder 2 (mm³), B= Nozzle Motor (0=closed, 1=fully open), F=Speed
mm/min. This will move the head to an absolute location at the specified feed rate. e.g. G1 X100
Y100 E50 F100 (move to 100,100 while extruding 50mm³ at 100mm/s)
Dwell S or P
S = Delay (seconds), P = Delay (milliseconds) This will cause all motion to delay for the specified
time period. e.g. G4 S100 (wait for 100 seconds) or G4 P500 (wait for 500 milliseconds)
Home [X Y Z]
Home specified axis, e.g. Home X Z will home the X and Z axis in sequence - X is always homed
first, and Z always last.
Move filament until slip [E / D F]
E = Extruder 1 (mm³), D = Extruder 2 (mm³), F=Speed mm³/min
This will feed the specified volume at the specified feedrate, until the extruder index wheel detects
that the filament is no longer moving.
Unlock door [S]
S = Override Safe Temperature (Bed) (°C)
This will unlock the door immediately if no S value is present, or allow the door unlock at a
specified bed temperature. e.g. G37 S50 will unlock the door when the bed temperature reaches
50°C.
Level gantry
Using the input from two G28 Z probes at least 100mm apart in the X direction, this command
automatically levels the gantry to make it parallel to the bed.
Level bed (compensate Z according to Y)
Using the input from two G28 Z probes at least 100mm apart in the Y direction, this command
automatically drives the Z axis during printing to keep the nozzle the same distance from the bed.
Use absolute coordinates on X/Y/Z axes (default)
This command causes Robox® to interpret all moves as ‘absolute’, i.e. move to the location
specified. e.g. G1 X100 Y100 will move to the fixed location 100,100. This is the default behaviour of
the firmware.
Use relative coordinates on X/Y/Z axes
This command causes Robox® to interpret all moves as ‘relative’ i.e. move to the location relative
to your current position. e.g. if the head is at position 100,100 - G1 X20 Y20 will move the head to
120,120, not 20,20.

This command tells the soware the location of the printhead - it is not necessarily the same as
the physical position of the head.
Tool 0 (Fine Nozzle - 0.3mm)
This command selects the fine printing nozzle.
Tool 1 (Fill Nozzle - 0.8mm)
This command selects the fine printing nozzle.
First layer target temperature [S] S=Override Temperature °C
This command sets the nozzle temperature for the first layer of printing using data supplied from
the reel EEPROM. [S] provides a manual override for custom temperature. e.g. M103 will set the
nozzle temperature to the value stored on the reel / previous value sent, M103 S240 sets it to
240°C.
Set nozzle target temperature [S] S=Override Temperature °C
This command sets the nozzle temperature using data supplied from the reel EEPROM. [S]
provides a manual override for custom temperature. e.g. M104 will set the nozzle temperature to
the value stored on the reel / previous value sent, M104 S205 sets it to 205°C.
Show temperatures and PWM output, voltage detection (T:aa @bb B:cc (^/$)dd A:ee *)
aa = Nozzle Temperature Setpoint (°C), bb = Nozzle Heater PWM (0-255), cc = Bed Temperature
Setpoint (°C), dd = Bed Heater PWM (0-255) - ^ denotes 240V supply, and $ denotes 115V supply,
ee = Ambient Temperature Setpoint (°C), = Ambient Fan PWM (0-255). This command shows the
status of all heaters and temperature settings.
Head Fan on [S] S=Speed (0-255)
This command sets the speed of the fan on the print head. e.g. M106 S255 sets the fan to 100%
power, M106 S128 sets it to 50%.
Head Fan o
This command turns o the head fan, but only if the nozzle temperature is lower than 60°C. The
minimum fan speed if the nozzle temperature >60°C is 50% (S128).
Wait for nozzle temperature to reach target
This command issues a stop to all commands until the nozzle reaches it’s target temperature.
Display current position [X Y Z B]
This command displays the current position of all axes e.g. M104 will output all positions to the
console in the form M104 X** Y** Z** B**.
Turn o motors until next move
This disables all stepper motors until a G0 or G1 is sent.
Set axis steps per unit [X Y Z E D B]
This command is only really for advanced use, as these values should never need to be changed.
It sets how many microsteps are equivalent to one unit of motion i.e. for X, Y and Z, this is 1mm, for
E and D, this is 1mm³ and for B this is the equivalent to the angle at full open.
Show Z delta
This command displays the dierence in height between the last two Z height probes.
Show firmware version
Displays the firmware version which is installed on the Robox®.
