Welcome

Congratulations on your purchase of the new S CLASS 2 cutter!

The S CLASS 2 cutters are built for sign-makers who demand the very best in cut quality.

Four versatile modes let you switch between Cutting, Cutting in FlexCut, Plotting or
Pouncing. So even if your workspace is limited, your output options aren't.

Unrivalled tracking delivers guaranteed accuracy on cuts up to 12 meters (40 feet) long.
This way you won't have to monitor your cuts, even when you're sending through long jobs.

The S CLASS 2 T series cutters with genuine tangential operation, and not simply "tangential
emulation," handle a wider range of materials and cut with unparalleled precision.

In short, the S CLASS 2 cutters take cutting signs to a new level.

This manual is a reference guide for installing and operating the S Class series cutters.
Minimum revisions needed for this manual:
Firmware cutter: 017 (MD9981)
Cutter Control version 5.1 (installed from Cutter Tools version 2.2.0)
USB driver: version 6.4
Camera driver: revision1.0.136

1.1 Unpacking the cutter

NOTE: Save the shipping box and any other packaging items in case the cutter

needs to be shipped. Do not ship the cutter without first completely repacking it

in its original packaging. A document explaining how to repackage is available.

WARNING: For safety reason no fewer than two people should be involved in
unpacking the cutter.

Before unpacking the cutter, make sure there is enough space to assemble the stand and to
set the cutter aside in order to insert the stand screws.

1.1.1 Removing the packaging from the cutter

1. Remove the straps and the staples and open the lid of the box.

2. The cutter is packed in foil and is situated in front of the box. The box, containing the

stand, is situated behind the cutter. The accessories are located at the bottom in a
separate box. Firstly, check whether everything is present.

3. Do not throw away the packaging. Shipping it without the original box voids any

warranty.

1.1.2 Setting up the stand

1. Verify whether the stand is complete. The box containing the stand should contain

following:

a. 2 legs, left and right
b. 2 feet, left and right
c. A horizontal panel
d. Media flanges
e. A total of 7 tubes for the [media] basket
f. A linen media basket
g. A bag of 4 casters, screws and other accessories to mount the stand

FIG 1-2

1-2 CONTENTS OF THE STAND BOX

2. Mount the horizontal panel between the two legs of the stand with four screws at each

side.

FIG 1-3

1-3 MOUNTING THE HORIZONTAL PANEL

3. Turn the stand upside down and mount the 2 feet at each side with four screws. Make

sure to position the feet in this way all the holes in the feet correspond to the holes in
the legs (left and right), as in the picture below (1). The four holes in the feet all point
towards the middle (2). Screw in the four casters.

4. Attach the four tubes for the basket on the left and right, as shown in figure 1-5 below.

Put the end cap (1) and the two saddle clips (2) on each tube in order to fix the tube in
its place. Position the shorter tube (3) at the rear side (side of the horizontal panel).

1-5 MOUNTING THE BASKET TUBES

5. Turn the stand upright and put the media basket on the horizontal panel as shown in

figure 1-6 below.

FIG 1-6

1-6 PREPARING TO INSTALL THE LINEN BASKET

6. Take one of the large c-shaped tubes and put it through the front hem in the linen

basket. Make sure the holes are oriented with the right side upwards, so that the tubes
click in place securely. Then put the tube on the two front tubes that stick out of the
feet. Slide the tubes together while pressing down the spring-loaded ball stopper until
the ball locks into place.

FIG 1-7

1-7 ORIENTATION OF THE HOLES IN THE C-SHAPED TUBES

7. Click a saddle clip onto one side of the tube. Insert the other end of the tube through

the middle hem of the linen basket and then into the hole in the leg of the stand. Guide
the other end of the tube into the hole on the leg and secure with a saddle clip.

Setup 1-4

8. Make sure the linen basket is guided under the horizontal panel. Take the last large c-

shaped tube and feed it through the rear hem in the linen basket. Then put the tube on
the two rear tubes that stick out of the feet. Make sure the holes are orientated with the
right side upwards, so that the tube clicks securely on the tubes. The finished stand
should look like the stand in the picture below (Figure 1-8).

FIG 1-8

1-8 COMPLETELY ASSEMBLED STAND FOR THE S CLASS 2 CUTTER

9. The right leg contains a hole in the foot and a cutout in the leg in order to guide the

power cable and data cable. If you plan to use these cable guides, then put the cables in
place before mounting the cutter on the stand.

1.1.3 Mounting the cutter on the stand

1. Carefully take the cutter out of the box and lay it on its back (first spread out the

cardboard of the stand box, and then rest the cutter on that cardboard). Insert the left
and right two screws and turn them 3 turns in. Do not put a screw in at the front.

FIG 1-9

1-9 POSITION OF THE SCREWS

2. Put the cutter on its stand. Put a lockwasher on the two remaining screws and put them

in the two remaining holes. Then secure all six screws.

3. Loosen the cutting head. Raise the pinch rollers to remove the protection strip from

underneath the pinch roller assemblies.

FIG 1-10

1-10 S CLASS 2 CUTTER, FRONT VIEW

1. Pinch rollers: The pinch rollers clamp the media to the drive system to ensure accurate

tracking. The S120(T) has one and the S160(T) and S 140(T) have two extra pinch rollers
to ensure that wide media stays flat in the middle. The outer drive pinch rollers have a
selectable pressure; the extra rollers in the middle can be enabled or disabled. Extra
pinch rollers can be added.

Number of pinch rollers S75 S120 S140 S160

Dual pressure 2 2 2 2

Low pressure 0 1 2 2

2. Touch panel: All cutter activity can be initiated from the 320x240 dot touch panel. The

panel displays information about the cutter’s current status and/or actions that need to
be taken.

3. Pinch roller lever: This lever is used to raise and lower the pinch rollers for media

loading.

Setup 1-6

4. Media drive sleeves: The media drive sleeves only move the media when the pinch

rollers are in the “down” position. The following table lists the number of sleeves
installed on each model of the S CLASS 2 cutters.

Number of sleeves

S75 (T) S120 (T) S140 (T) S160 (T)

Short sleeve 4 7 8 9

Long sleeve 1 1 1 1

5. Tool carriage: The tool carriage is the carriage for the knife holder, pen or pouncing

tool. It also holds the Optical POSitioning sensor (OPOS) and a cut-off knife to cut a
sheet from the roll when a job is finished.

6. Cutting strip: A self-healing orange strip helps avoid any damage to the knife tip when

no media has been loaded. Since cutting is done on the cutting strip, it is essential that
the strip remains intact.

7. Pouncing strip: An extra black strip to pounce on.

8. Tool holder: The left end cap has a rim so it can be used for tool storage.

9. Screws to secure the cutter base: Make sure all three screws are secured at each side

before the cutter is used.

10. Media basket: The stand and linen media basket come standard with all S CLASS 2

cutters.

1.3.1.3 Safety precautions

WARNING: The S CLASS 2 cutters use razor-sharp knives. Touching the knife

with bare hands may cause injury. Do not touch the knives while the machine is
cutting.

The cutter comes with a tool to insert the knives in the knife holder. Use this tool to prevent
injury. Put used blades in their original packaging for disposal.

The entire base plate should be considered as a dangerous area when the cutter is switched
on and off. The tool carriage can move from the left to the right and the yellow media
sleeves are sharp and can grab loose objects, clothing or body parts.
The cutter constantly measures the current through the motors. If the machine detects the
current is too high, then the current will be cut off to the motors and a fatal error message
will be displayed on the control panel.
Make sure to observe all the caution labels on the cutter.

1.3.2 Operating environment

Environmental conditions can significantly affect the machine’s performance.
The environmental conditions of the machine (without media) are as follows:

Operating Temperature

1.5 Connecting the cutter to a computer

The S CLASS 2 cutters support bi-directional USB and Ethernet connectivity. When both
ports are connected at the same time, the port that receives the data first will remain active
and the other port will be deactivated.

1.5.1 USB connection

The USB cable should be 5 meters (16 feet) or less in length. The connector on the cutter
side of the cable should be USB series B 4-pin. The connector on the computer side of the
cable should be USB A 4-pin.

1.5.1.1 Connecting the S CLASS 2 cutter to a PC, using a USB cable

NOTE: When installing a cutter, make sure the user has administrative rights

and UAC is deactivated or set it to its lowest level (not applicable for Windows

XP or earlier versions).

1. Power-off the cutter.

2. Insert the S CLASS 2 CD into the computer’s CD-ROM drive.

3. Choose to run Windows_autostart.

4. Choose the language and click on install USB driver. Wait for the driver to install.

5. Connect one end of the USB cable to a USB port on the computer.

6. Connect the other end of the USB cable to the USB port on the back of the cutter.

7. Power on the cutter (see section 0) and return to the computer.

The Found New Hardware Wizard should appear on the computer screen and install the
USB driver.

8. Click “OK” and follow the instructions, provided by the Wizard.

9. Restart the computer.

NOTE: When connecting a cutter to a computer for the first time, using the USB

cable, the computer will detect the cutter and install the USB driver if the setup

program was run. If the setup program was not run prior to connection, then

install the program while the

cutter is connected and switched on. After the

progr

am is run, the computer will detect a new device and install the correct

driver automatically.

NOTE: In order to connect more than one cutter to one computer, see the
section on the USB class.

NOTE: It is recommended to always use the latest version of the driver. The CD

is made this way it downloads the latest version automatically. If no internet

connection is available, then it is possible that the driver on the CD is outdated.

1.5.1.2 Connecting the S CLASS 2 cutter to a Mac using a USB cable

 Mac OSX

Most recent cutting software does not need a driver installation when a computer is
connected to the cutter. The software that controls the driver is built into the cutting
software.

1.5.2 Ethernet connection

A couple of parameters need to be set when connecting a cutter to the Ethernet. It is best to
check a couple of network settings or ask the network administrator for following info:
Is the network working with a DHCP server or not?
If so, what is the lease time and what is the IP pool range of the DHCP server.
If not, then find out what the used IP range is.
Also ask for the value of the subnet mask.
If the network administrator can already provide a free IP address and the value of the
subnet mask, then go directly to the procedure Case set everything manual

.
If the values are not known at front and need to be searched for, then follow the below
procedure.

 In case the DHCP server is used:

If no lease time is set (the lease time is infinite) then no parameters have to be set on the
cutter. Just connect the cutter and write down the IP address to set up the cutting software.

Check the IP address in the communication menu:

1. Power on the cutter (see section 1.4) and connect the Ethernet cable.

2. Press status bar

3. Press LAN

4. Press Status

The IP address (and other
network settings) are shown
on the screen.

If a lease time is set, then use a static IP address. If the IP pool range is known, use an
address outside this range. If this is not possible, try and change the IP pool range of the
network so a couple of addresses are vacant to be used as a static address.

Setup 1-15

NOTE: Be careful when changing the IP pool range of a network. Check if there

are no devices attached to the network that uses IP addresses outside the new
IP pool range (use the ping command– see

ping).

If such devices are found,

switch them off and back on after the pool range is changed.

If an address can be chosen outside the IP pool range, check if this address is vacant with
the ping command on a computer in the network (use the ping command– see ping

).

If no address can be chosen outside the IP pool range (the range is not known, or the range
cannot be changed), check the manual of the router if it is possible to link a static IP address
to a mac address. If so, choose a free IP address (use the ping command for this – see

check
if chosen IP is free) and link it to the mac address of the cutter in the router setup or DHCP

setup.

NOTE: it is recommended to work with a static IP address because cutting

software uses a static IP address to send the data to.

If the lease time of the

DHCP server isn’t infinite or if no static IP address is used, it is possible that the
IP address of the cutter suddenly changes and that the cutter software does not

function anymore.

When it was impossible to obtain an address with the above procedures, a ‘trick’ exists to
find a vacant address. In order to do so, check the IP address and subnetmask from the
computer and choose an IP address that is ‘far’ from the IP address of the computer ( add or
subtract 98, but make sure it stays in de range of 2 – 250 )

Check IP config of the computer:

For Windows:

Press simultaneously and . Type “Cmd” (without the “ “) and click on OK. A
program box opens. Type IP config in this box.

For Mac:

Click on the apple menu, system preferences and network. The IP address and subnet mask
are visible.

For Linux:

Go to the Applications Accessories Terminal (or search for terminal). Once the terminal
window is opened, type ifconfig.

Check if the chosen IP address (xxx.xxx.xxx.xxx) is vacant:

S CLASS™ 2 cutter User’s Manual

For Windows:

Press simultaneously and . Type “Cmd” (without the “ “) and click on OK. A
program box opens. In this box type ping xxx.xxx.xxx.xxx (xxx.xxx.xxx.xxx being the IP
address that is chosen for the cutter). If there is a reply, this means that the IP address is in
use and cannot be used for the cutter. If there is no reply, this address is vacant and can be
used for the cutter.

For Mac:

Press simultaneously the , and key to open the applications
folder. Then click on Utilities, and Network utilities. In the newly opened window, click on

the ping tab. Enter the IP address (xxx.xxx.xxx.xxx) and click on . If there is a
reply, this means that the IP address is in use and cannot be used for the cutter. If there is no
reply, this address is vacant and can be used for the cutter.

For Linux:

Go to applications Accessories terminal (or search for terminal). Once the terminal window

1.6 Loading media

The following procedures apply mainly to the use of roll media. If you are using sheets,
there are two options:
For long sheets, roll up the sheet so that the alignment is identical to that of a roll.
For short sheets, the alignment is not so important. If the sheet is cut off perpendicularly, it
can be aligned to the front border.

1.6.1 Pinch roller positioning

Proper movement of the media will only occur if the media is driven by the two outer pinch
rollers, which are correctly located over two drive sleeves.

The pinch rollers are lowered or raised simultaneously by means of the pinch roller lever
arm, located on the right-hand side of the cutter. The pinch rollers must be lifted to allow
vinyl loading, during which the media is fed from the rear of the cutter to the front. When
raised, the pinch rollers can be moved manually to the left or the right along the pinch roller
shaft.

CAUTION: Always make sure that the pinch rollers are fully raised before sliding

them to the left or right.
Always hold the assembly at the side of the pinch roller to move it from left to
right. Do not reposition the

pinch roller by holding the assembly at the rear of

the machine.

The pinch rollers MUST be positioned correctly and lowered onto the media before an
automatic load sequence is initiated. Make sure that all the pinch rollers are positioned
above a drive sleeve. The outer left pinch roller should be positioned in one of the detents
(click position), just underneath a white triangular label. The outer right pinch roller should
be positioned somewhere over the long drive sleeve. Click positions are located at the
edges of the sleeve (area marked with a white triangular label).

FIG 1-15

1-15 POSITION PINCH ROLLERS

CAUTION: Always leave the pinch rollers in the “up” position when the cutter is

not in use. Leaving the pinch rollers in the “down”

position for a long time will

result in a flat spot in the pinch rollers, which will seriously [negatively] affect

tracking performance and cutting quality.

NOTE:

When the pinch rollers are raised

during a job, the cutter will

immediately stop and move the carriage to the right side.

S CLASS™ 2 cutter User’s Manual

Setup 1-19

1.6.2 Pinch roller pressure setting

The S CLASS 2 cutters are equipped with selectable pinch roller pressure. The pressure can
be set to “standard” or “low.” The change in pressure should only be done when the pinch
rollers are in the down position. When reduced pressure is needed, it is advised to set
autoload to ‘ASK’. Then the cutter will not start to load the vinyl when the pinch rollers are
set down or when the cutter is switched on. A message will appear on the touch screen,
giving the user time to change the pressure on the pinch rollers.

NOTE: Each time the pinch rollers are raised, the pressure is automatically reset
to full pressure.

FIG 1-16

1-16 REDUCING PRESSURE

To work with reduced pressure, do the following:

1. Set AUTOLOAD to ASK (see the section on Autoload:).

2. Load the media in the cutter (see the section on Media load procedure).

3. Push the lever of the two outer pinch rollers upwards and inwards (toward the machine)

– see figure above.

1-20 FEEDING ROLL MEDIA WITHOUT USING MEDIA FLANGES

5. Start feeding the media from the rear of the machine. Pass the media underneath the

pinch rollers towards the front of the machine.

6. Position the left media edge on the left-most drive sleeve and check whether the right

media edge is positioned over the long drive sleeve. Then position the left and right
pinch rollers.

The pinch rollers should be positioned over the drive sleeves about 3 to 15 mm (0.1” to

0.6”) away from the media’s outer edges (1). Then pull the media while holding the
flange at the back so the media is tight. Make sure the front media sensor is covered (2).

FIG 1-21

1-21 MEDIA POSITION

In circumstances where the above procedure does not work, because the media is too
narrow to reach the long drive sleeve, try positioning the left media edge over the
second left drive sleeve and position the right media edge somewhere over the long
drive sleeve. Continue moving the left pinch roller toward the long drive sleeve until
both pinch rollers click in their designated position and directly over the edges of the
vinyl.

In all cases, both edges of the media must cover a drive sleeve. If this is not the case,
reposition the roll of material to cover the drive sleeve.

7. Make sure that the media follows a straight path from the roll of material. To accomplish

this, slide the media roll and flange guides from the left to the right along the media
support rollers.

1.6.4 Media load procedure

CAUTION: Do not place any objects in front of, or behind, the cutter that could

interfere with cutter operation. Make sure the media is free to move forward
and back. Keep hands, hair, clothing and jewelry away from moving parts.

While the cutter is activated, it will automatically start executing a minimal loading
procedure as soon as the pinch rollers are lowered. The load procedure will also start when
the cutter is switched on while the media is already in the machine and the pinch rollers are
in the “down” position (this is not recommended). Always keep the pinch rollers in the up
position while the cutter is not in use.

The minimal loading procedure consists of:

 A media-width measurement.
 The media is unwound over a length, equal to the width measured between the

outer two pinch rollers.

 A simultaneous 45° axial move of the drive drum (sleeves) and cutting head.

The cutter is now ready to receive files from the computer.
When receiving a job from the computer, the cutter will automatically pull the required
media from the roll. This happens gradually and the length of the used vinyl is equal to
several measured widths of the media.

IMPORTANT:

Tracking of longer signs can only be guaranteed when the full

load procedure is performed!

Full media load procedure:

WARNING: Each keystroke can initiate an internal test or movement of the

head or media. Keep fingers and other body parts away from the cutting area.

head or media. Keep fingers and other body parts away from the cutting area.

There are hazardous moving parts.

1. Power on the cutter and load the media.

2. Press on pressure

4. Or fill in the new value

after pressing Numpad.

1. Press to perform the internal knife pressure test.

2. Press to confirm the chosen knife pressure and exit the menu.

3. Press to leave the pressure unchanged.

and the blade tip visibly scratched the front side of the media backing when the vinyl is
removed. The blade should never cut in the backing but should only slightly scratch the
silicon coating and first few fibers of the backing material. Because the knife pressure
setting depends on the thickness and type of the media, adjusting the knife pressure will
require some practice. In general, the knife depth must be increased when using thicker
types of vinyl and decreased when using thinner types of vinyl.

NOTE: After setting the cutting depth and/or the knife pressure, perform a

thorough visual check of the knife blade, protruding from the knife holder and

test the cutting results on a scrap of vinyl media.

WARNING:

Do not operate the cutter if the knife blade cuts through the media

backing, as this will seriously damage the cutter's rubber cutting strip and the

knife.

NOTE: For most vinyl cutting operations, the knife blade tip will be barely

visible at the bottom of the knife tool. If the knife blade tip is clearly visible, then

the cutting depth must be readjusted.
To prevent damage to the cutter, check the depth of the knife blade tip and the

quality of the cut each time you load a different type of vinyl into the cutter.

1.7.1.2 Pen installation

The S CLASS 2 drag cutters can also be operated with a plotter-type pen. After replacing the
knife with a pen, the cutter can be used as a plotter to draw draft plots of new or existing
designs on paper.

1. Loosen the head clamp screw and swing the clamp arm back. Then remove the tool

from the clamp.

2. Install the pen in the rear slot, close the clamp arm and tighten the clamp screw.

3. The change of tool can either be done on the touch panel with Summa Cutter Control

(PC only) or with the cutting software.

Selecting the pen operation disables the knife offset correction and changes the pressure to
“pen pressure.”

NOTE: The information on the touch panel shows the tool, which was currently

selected by the cutter. Make sure the cutter’s tool setting matches the actual

tool in use.

1.7.1.3 Pouncing pin installation

The S CLASS 2 drag cutters can also be operated with a pouncing tool. After replacing the
knife with a pouncing tool, the cutter can be used as a paper pouncer.

1. Loosen the head clamp screw and swing the clamp arm back. Then remove the tool

from the clamp.

2. Install the pouncing tool in the front slot, close the clamp arm, and tighten the clamp

screw.

3. The change of tool can either be done on the touch panel with Summa Cutter Control

or with the cutting software.

Selecting the pouncing tool operation disables the knife offset correction, changes the
pressure to “pouncing pressure” and will add “pouncing gap” to the tool properties.

NOTE:

The information on the touch panel shows the tool, which is currently

selected by the cutter. Make sure the cutter’s tool setting matches the actual

tool in use.

CAUTION: Before starting to pounce, check whether the pouncing tool is

positioned above the black pouncing strip. If the pouncing tool is mounted in

the rear slot of the clamp, the cutting strip will be damaged irreversibly!

1.7.2 Cutters with tangential head

1.7.2.1 Tangential knife installation

A knife is pre-installed in your cutter. For safety reasons, the knife depth has been set to
zero. Simply turn out the knife (see fig FIG 1-28) to start cutting. Below is the complete
description of how to remove or install a knife.

NOTE: To benefit fully from the advantages of the tangential knife, the amount

the knife extends is very important. The knife pressure may not control the knife
depth. The

two rollers of the nosepiece should always touch the media, thus

controlling the knife depth.

 Removing the tangential knife

1. Turn the knife holder counterclockwise. The holder will rise up, eventually making it

possible to lift the knife holder out of the tangential head. The nosepiece is situated
underneath. Remove this part if another tool is used in the cutter.

FIG 1-28

1-28 REMOVING THE TANGENTIAL KNIFE HOLDER

2. The knife can be removed from the knife holder by using something like a flat

screwdriver to pry in the groove between the knife and the knife holder.

NOTE: The knife pressure can also be used to check the knife depth (which is

controlled by the amount the knife extends out of the nosepiece). If the correct
knife pressure is raised by 150 gr, then the knife should not cut through the

backing of the vinyl. If it does, the knife depth needs to be reduced.

CAUTION: After setting the cutting depth and/or the knife pressure, perform a

thorough visual check of the knife blade, which protrudes from the knife holder,

and test the cutting results on a scrap of vinyl media!

WARNING: Do not operate the cutter if the knife blade cuts through the media

backing as this will seriously damage the cutter's rubber cutting strip and the

knife.

NOTE: For most vinyl cutting operations, the knife blade tip will be barely

visible at the bottom of the knife tool. If the knife blade tip is clearly visible, the
cutting depth must be readjusted.
To prevent damage to the cutter, check the depth of the knife blade tip and the

quality of the cut each time you load a different type of vinyl into the cutter.

All the different tools have one parameter name in common: the pressure.
Each tool also has its specific parameters.
Tool parameters can be changed by either changing them in the current user, or simply by
changing the user (see section 2.1.5).

NOTE:

The S CLASS 2 cutters will only perform according to specifi

cations if a
genuine Summa knife, pen or pouncing tool is installed. Do not replace the
standard knife, pen or pouncing tool with products from other manufacturers.

WARNING: Each keystroke can initiate an internal test or movement of head or

media. Keep fingers and other body parts away from the cutting area. There are

hazardous moving parts.

2.2.4 Calibrating a tangential knife

The purpose of the knife calibration routine is to detect and, if necessary, to correct
problems related to the concentricity of the tangential knife blade.

NOTE:

Knife calibration should be done each time the knife is changed and

should be checked if the knife shows signs of wear.

Knife calibration errors may be due to any of the following causes:

• Origin deviation. The knife tip is slightly rotated in relation to its theoretical 0° angle.
This error can be corrected by adjusting the origin.

• Lateral deviation. The knife tip deviates from its theoretical center in the lateral
direction. This error can be corrected by adjusting the lateral parameter.

• Longitudinal misalignment. The knife tip deviates from its theoretical center in the
longitudinal direction. This error can be corrected by adjusting the longitudinal
parameter.

type of vinyl). Test pattern 1 and 4 are the most important test patterns. They
should be as close to perfect as possible.

Start with the setting of the origin, and then set the other parameters.

Origin correction

If the clear cut line in test pattern 3 is located too much to the right, increase the value of
the origin. Begin in steps of 20, and lower the steps when nearing the correct origin
setting.
It helps sometimes to gently feel the pattern to find out which side has the clear cut line.
If the clear cut line in test pattern 3 is located too much to the left, decrease the value of
the origin. Begin in steps of 20, and lower the steps when nearing the correct origin
setting.

Lateral correction

Weed out (remove) the rectangle in pattern 1 and in pattern 4. If the test pattern looks
like the one below, decrease the value of the lateral parameter to correct the closing cut
lines.

However, if the test cut resembles the pattern below, increase the value of the lateral
parameter to correct the closing cut lines.

Longitudinal correction

Weed (remove) out the rectangle and, if you obtained a pattern like the one below,
decrease the value of the longitudinal parameter to correct the closing cut lines.

However, if the test cut resembles the pattern below, increase the value of the

2.3 How to set the cutting speed

The actual speed at which the tool moves is determined by 4 different parameters. Speed
(and acceleration) while the tool is down; speed (and acceleration) while tool is up.
These 4 parameters have been bundled in one parameter to change the speed fast and
easily.
This overall parameter is called “velocity” and is the speed the cutter uses when the tool is
down. If velocity is raised or lowered, then the other parameters are also raised or lowered
accordingly.

There is one fixed speed: the speed at which the cutter pulls the media from the roll. This
speed is fixed at 200mm/s (8ips).

Setting the cutting speed:

1. Power on the cutter.

 In case the media is loaded:

3. Select new velocity,

scroll with More, if

necessary.

 Case media not loaded:

2. Press Settings

3. Press Velocity

4. Select the new velocity,

scroll with More, if
necessary.

Press to confirm the chosen knife offset and exit the menu, press to leave the
knife offset unchanged.

NOTE: Sometimes the cutter feeds the material too fast and the media has no

time to settle and fold into the basket. A fifth speed parameter is designed for
such cases. The speed of long X-axis vectors is reduced automatically so that the

media does not bulge (see section 0).

2.4 How to make sure the sign has the correct size

(Length Calibration)

The S CLASS 2 cutters are friction-feed machines. This means that the cutting length
depends on the thickness of the material.

The cutters have been calibrated in the factory for standard 2-mil cast or 3-mil calendared
vinyl. Each user (the S CLASS 2 has a total of 8) can hold a different calibration factor.
This is very helpful for multi-colored signs. It ensures that the parts in different colors match
up, even if different types of vinyl media are used.

NOTE:

For standard use, it is not necessary to calibrate the machine. With
standard vinyl the accuracy is within 0.2%. However, if high accuracy between

different vinyl or colors is needed, then calibration is necessary.

Calibrating the media (Length calibration):

1. Power on the cutter, load the media, and mount the knife (see section 1).

NOTE: The wider and longer the loaded media, the more accurate the

calibration will be. Use a piece of vinyl of maximum width and a length that is

approximately 1.5 times the width.

2. Press Settings

3. Press More

4. Press length calibration.

The cutter will reload the media and perform the length calibration test. Take out the media
and measure the length of the cut line with a ruler (measuring device). The length that has to
be entered is the distance between line 1 and line 2 as shown in the figure below.

1 2

FIG 2-7

2-7 LENGTH CALIBRATION PATTERN

NOTE: The cutter will only be as accurate as the accuracy of the calibration itself.

If the ruler (measuring device) is inaccurate, then re-calibrating may worsen the
cutter’s accuracy. The accuracy of the calibration will be reflected directly in the
cuts. Set the cutter to Metric to do the calibration. It is more accurate than the

English unit system (see section 0).

3 OPOS (Optical POSitioning)

3.1 Introduction

Contour cutting is made possible by the S CLASS 2’s highly accurate Optical Positioning
System (OPOS).

The OPOS sensor, which is mounted on the right-hand side of the tool carriage, registers
printed squares that are placed around the graphic. Because of this registration process,
OPOS can determine the exact position of the printed graphic.

The sensor drops automatically while registering the marks and rises again after completing
this task. The improved sensor can read virtually any kind of media-mark combination.

NOTE: The T4 S Class models use a USB camera instead of the OPOS sensor for

registering the OPOS marks. Section 3.5 describes the differences between the

sensor OPOS and the OPOS CAM.

3.2 Basic OPOS operation

In general, contour cutting includes the following steps:

a. Create a graphic.

b. Print the graphic (laminate if necessary).

c. Load the graphic into the cutter.

d. Set the necessary parameters for the OPOS sensor.

e. Load the media and register the marks.

f. Cut the graphic.

Many versions of cutting software have the built-in capability to make contour cutting user­friendly and automatic. Please refer to the user’s manual that came with your software or
contact your software dealer for specifics.

The following paragraphs are not a detailed description of the complete procedure for
contour cutting. They are merely a guideline with useful recommendations and tips.

S CLASS™ 2 cutter User’s Manual

Contour Cutting 3-2

3.2.1 Creating the graphic

1. Create the graphic and contour cut line(s). For easier handling, place the contour line(s)

on a different layer.

NOTE: Some RIP software require that the contour lines are defined in special

color (spot color). Please refer to the user’s manual that came with your software

or contact your software dealer for specifics.

NOTE:

Do not place contour lines along the edges of graphics or the slightest
movement in the media may result in an unsatisfactory cut. Instead, practice one

of the following techniques.

1. Place contour lines just inside the graphics (recommended) (1).

2. Place contour lines outside the graphics (2).

3. Create thick borders around graphics and place contour lines inside these

borders (3).

Contour Cutting 3-3

3.2.2 OPOS XY

A function is available in OPOS to compensate curved printing errors in the Y-axis also. This
function is called OPOS XY. An extra line needs to be printed with the design to be able to
use the OPOS XY functionality.

The OPOS sensor will measure points along the extra line when OPOS XY is enabled. The
number of measuring points will be determined by the cutter and will depend on the width
of the design.

NOTE:

The default setting for OPOS is OPOS X. If the OPOS XY functionality is

needed, then the user must change the setting ‘alignment mode’ in the OPOS

Setup to OPOS XY manually on the control panel or via the cutting software.

NOTE: Some cutting software do not support the OPOS XY feature. If they also

send the alignment command ‘OPOS’ to the cutter, then they block the cutter’s
OPOS XY feature. If it is possible to define a line manually in the design, so that it

meets up to the specifications above, the blocking of the software can be
neutralized by using the setting: ‘FORCE OPOS XY’ in the alignment mode.

The line can be added between or above the front Y marks. The distance between the
center of the marks and the line should not be more than 20mm( distance 1). The left and
right margin between the line and the mark should be 10mm for optimal sensing (distance

2). The line itself should be 3mm thick. There should be at least 5mm white space above the
line.

S CLASS™ 2 cutter User’s Manual

Contour Cutting 3-4

3.2.3 Printing the graphic

1. Print the graphic and its marks with a printer (scale = 100%). When printing on a roll,

make sure that the graphic’s origin mark coincides with the media’s origin (1).

1

2. Make sure there is at least a 1cm (0.4in) margin on each side of the graphic (2). A 2cm

(0.8in) margin is preferable. There should also be a front margin of 1 cm (3).

2

3

3. Leave a margin of at least 4cm (1.6in) when using sheets or when cutting the print from

a roll (4).

S CLASS™ 2 cutter User’s Manual

Contour Cutting 3-5

3.2.4 Orientation

Minding the orientation is very important when loading the printed media for contour
cutting. With some cutting software, it may be necessary to collectively rotate the contours
and marks, so that the origin mark (1) is situated in the bottom left corner of the cutting
area (2), as viewed on the screen. If the cutting software’s default orientation is not set to
“landscape,” the contours and marks will need to be rotated.

Orientation needed in most cutter software. Orientation when using WinPlot

Make sure that the cutter is connected to the computer and that the cutter is switched on.
The cutter’s touch screen should indicate the cutter is ONLINE.
Click Cut from within the cutting software. The cutter should begin cutting the contour and
return to the ONLINE status when finished.

1 2

2

NOTE: Mind the orientation when working from a roll or a sheet. If a complete

roll is printed, then the jobs are loaded “upside down” into the cutter. Check the

orientation before starting to cut.

S CLASS™ 2 cutter User’s Manual

Contour Cutting 3-6

3.2.5 Registering the marks

Load the printout into the cutter as described in section 1.6. Make sure the mark, indicating
the origin, is situated at the bottom right corner of the cutter.

The cutting software will initiate the special load procedure after sending the parameters. In
standard mode, the cutter will then prompt the user to position the head to read the first
mark.

NOTE:

The cutter can be set this way the user does not need to intervene after

the computer has sent the command to start the OPOS job. Refer to section

3.4

for these settings.

Use arrows to maneuver the
knife on top of the first
mark. Press Apply to
confirm.

The cutter will reload the media to check if the loaded length matches with the used OPOS
parameters. Then it will return and read the marks.

NOTE: If a mark cannot be read, the user will have the option to re-position the
knife (sensor) or to abort.

NOTE: If an error occurs or the cutter cannot read the marks after three

attempts, the following message will be displayed: ”Marks could not be sensed”.

Press to continue.”.

3.2.6 OPOS paneling

With this option, the job can be divided into panels in order to avoid moving the media
unnecessarily back and forth. When OPOS paneling is activated, all cut data will be cut in
panels. The size of the panel will be the distance between the OPOS marks in the X-axis.

OPOS Panels can be set to OFF or ON. When set to ON, the cutter will only load 2 marks in
the X-direction when loading OPOS and read the marks. The rest of the marks will be read
during unrolling the media, one panel at a time.

NOTE: Do not use software paneling when using OPOS paneling.

3.3 Calibrating OPOS

To ensure that OPOS is working accurately, two calibrations are necessary: the OPOS
calibration and the media calibration. The OPOS calibration is the calibration of the distance
between the knife tip and the sensor. The media calibration “teaches” the cutter the
reflection levels of the mark color and the media color.

NOTE:

Although the OPOS sensor has been calibrated in the factory, Summa
recommends doing a test in order to determine how well the factory-set
parameters work with the materials you are using. If the accuracy is not what is

expected, then perform the OPOS calibration.

3.3.1 OPOS calibration

1. Switch the cutter on and load black vinyl with white backing.

NOTE: Black vinyl with white backing MUST be used when calibrating OPOS.

2. Press Settings

3. Press More

4. Press OPOS.

The cutter will cut out a
square, measuring
approximately 9.5x9.5mm
and move the square
forward. “Weed out
Rectangle” will appear on
the display.

5. Press Calibrate OPOS

6. Carefully weed the

square, making sure the
edges stay intact. Press

Back.

OPOS will read the edges of the square and calibrate itself accordingly.

NOTE:

In order to keep the accuracy of the OPOS sensor as high as possible, do

this calibration each time the knife is been replaced.

3.3.2 Media calibration

Media calibration ensures that the sensor is able to recognize the marks. OPOS is calibrated
at the factory to work on a wide range of media. However, certain media -- such as those
with a high gloss -- may not work with the default settings. Before working with such
materials, perform a media calibration test. This test will alter OPOS’s sensitivity so that it
will read the marks with greater reliability.
Print a square measuring at least 4x4cm on the used media. Make sure to use the same ink
than the one when creating the registration marks.

NOTE: It is not recommended to do a media calibration for OPOS. If the media

calibration is done and results didn’t improve, set the media calibration value

again to default : 30 (the procedure explains this at a later stage).

Perform the media calibration:

1. Turn on the cutter and load the vinyl with the printed square.

2. Press Settings

3. Press More

4. Press OPOS.

The cutter allows the user to
choose to either measure the
media or to fill in a
previously recorded value.

5. Press Calibrate media

6. Press measure.

The cutter will make a

The cutter will make a circular movement while it measures the reflection of the mark color.
It will briefly display the measured values. Then it will show a value that is characteristic for

this media color – mark color combination. Store this value for future reference.

NOTE: An error message may appear if the sensor is not able to differentiate

between black and white. Make sure that the test has been performed correctly.
If OPOS is not able to sense the marks, one of the manual alignment methods

(see 4.3.1.10) should be used.

3.4 Automating OPOS tasks

For standard OPOS jobs, the user only needs to set the tool above the first mark to start the
job. OPOS allows the user to automate certain tasks, thus reducing user intervention and
production time. There are several types of automation.

Automatic start of the OPOS job

This is controlled by the parameter OPOS origin. With a combination of this parameter
setting and/or a special origin setting during the load of the media, the user doesn’t have to
set the tool above the first mark to start an OPOS job.

Multiple copies of the same job

When cutting multiple graphics, the user only needs to maneuver the OPOS sensor above
the origin mark of the first graphic. Cutting subsequent graphics does not require additional
user input.

There are two multiple-job situations in which OPOS can be used:

a. When cutting multiple (copies of a) graphic(s) on the same media roll.
b. When cutting the same graphic on multiple media sheets.

Most automated tasks are organized from within the cutting software. However, when the
same graphic contour needs to be cut out, the automatic tasks may also involve some
manual manipulation.

Before using the automating features, note down the amount of your cutter’s RAM. If the
cutter’s RAM is greater than the job’s file size, then the automating features can be used. If
the cutter’s RAM is less than the job’s file size, then the automating features cannot be used.

Unattended contour cutting (roll to roll)

A special barcode can be printed together with the job. This barcode can then be used to
access the correct cutting data, so the cutter can cut one job after another without user
intervention.

3.4.1 OPOS origin

The parameter OPOS origin is created to automate the start of the OPOS procedure. This
parameter has 4 settings. The usage of this parameter depends on the chosen OPOS mode.
If the OPOS is OPOS barcode or OPOS Sheet, then this parameter has no effect.
The useful combinations are visible in the below table.

3.4.1.1 In combination with OPOS X mode

The OPOS Origin is set to ‘Mark’.

This is the default setting. Upon receiving an OPOS job from the computer, the cutter will
prompt the user to set the tool above the first mark and press Apply. The cutter will then
start searching for the OPOS mark around that position.

The OPOS Origin is set to ‘Current position’.

Upon receiving an OPOS job from the computer, the cutter will immediately start looking
for the mark when it receives an OPOS job from the computer, without waiting for the user
to move the tool. Therefore, the user will have to set the tool above the first mark while
loading the material.

If the OPOS origin is set to either ‘XY-correction line’ or ‘Center of media’, then the cutter will
react as if the parameter was set to ‘Indicate mark’

3.4.1.2 In combination with OPOS XY mode

The OPOS Origin is set to ‘Mark’.

This is the default setting. Upon receiving an OPOS job from the computer, the cutter will
prompt the user to set the tool above the first mark and press Apply. The cutter will then
start searching for the OPOS mark around that position.

The OPOS origin is set to ‘Indicate line’

Upon receiving an OPOS job from the computer, the cutter will prompt the user to set the
tool under the OPOS XY line and press Apply. The cutter will then start searching for the
OPOS XY line by slowly moving forward the media. Once it has found the OPOS XY line, it
will follow this line to the right until it finds the first mark and will then start searching for
the actual mark.

S CLASS™ 2 cutter User’s Manual

Contour Cutting 3-13

The OPOS origin is set to ‘Current Position’

Upon receiving an OPOS job from the computer, the cutter will immediately start searching
for the OPOS XY line by slowly moving forward the media. Once it has found the OPOS XY
line, it will follow this line to the right until it finds the first mark and will then start searching
for the actual first mark. Therefore, the user will have to set the origin under the OPOS XY
line, immediately after the media has been loaded.

This setting was created for jobs that are aligned at the left side and differ a lot in size on the
roll. The origin/tool can then be set to the left of the media, under the OPOS XY line in order
to be able to find the origin mark, even if it is situated far from the right side of the media.

OPOS origin is set to ‘Centre of media’

Upon receiving an OPOS job from the computer, the cutter first sets the OPOS sensor in the
middle of the media. Then it will start searching for the OPOS XY line by slowly moving
forward the media. Once it has found the XY line, it will follow the XY line to the right until it
finds the first mark and will then start searching for the actual mark.

This setting has been created for jobs on a roll where the width of each job is at least half
the width of the media (this is usually the case; otherwise there is lots of wasted media).
This method is slightly slower than the previous method.

If the same graphic design needs to be printed on multiple sheets, this feature can be used.

NOTE: The sheets should have more or less the same size, and the graphics on
them should be oriented and positioned the same way.

NOTE: OPOS sheet mode ignores the parameter OPOS origin, so the tool will

always have to bet set manually for the first job.

First, load the media and check whether the parameters of the OPOS marks are set correctly.

Cutting the same graphic on multiple media sheets:

1. Press Settings.

2. Press OPOS sheet mode.

3. Press Apply.

4. Do the job on the first sheet.

The cutter will stop after the first contour has been cut and will come online again.

5. Raise the pinch rollers and remove the sheet manually.

6. Insert the next sheet into the cutter. Lower the pinch rollers.

NOTE:

The second and any following sheet must be loaded in the cutter at the
same position and orientation as those from the first sheet. When in OPOS sheet
mode, the cutter stores the distance between the edges of the sheet and the first

OPOS mark.

NOTE: Use easy orientation points to be able to quickly position the sheet. In the

figure below, a rim of the base plate and the side of the pinch roller assembly are

used to align the sheets.

3.4.4 OPOS Barcode

3.4.4.1 Introduction

The S Class 2 cutters can also read a barcode. Certain RIP’s have the ability to print a barcode
together with the OPOS markers. This barcode can then be used to identify the job and
retrieve the needed cut data automatically from the computer.
A program has to run on the computer that will act as a barcode server. This program
monitors the connection with the cutter. Once a barcode is sent from the cutter, it will
search for the corresponding file with the correct cut data on a server (where the RIP has
written the cut file) and then send this file to the cutter. Once the file is sent, the barcode
server waits again for a new barcode. In this way a complete roll can be cut without
intervention of the user.
Depending on the program (barcode server) the procedure will have to be started from the
control panel of the cutter or from the program (Summa’s barcode server contains both
options). To start the barcode procedure from the program, refer to the user manual of the
program in question. To start the procedure from the control panel follow the procedure
described in section 3.4.4.3.

3.4.4.2 Activation of the barcode

Before the first use, the barcode function needs to be activated. The activation happens
through our website (www.summa.eu/barcode

). The serial number of the cutter is needed
for this activation. The serial number can be found on the serial number label on the back of
the cutter or in the system setup menu. It is recommended to get the serial number directly
from within the system setup menu.

3.5 OPOS CAM

3.5.1 General

The T4 S Class models use a small USB camera instead of the OPOS sensor for registering the
OPOS marks. All normal OPOS procedures, as described above in this manual, can be used,
provided that the registering device is a camera. However, there are some small differences.
These differences are described in this section.

FIG 3-2

3-2 OPOS CAM

The camera option cannot function if it is not connected to the computer. If the cutting
software is not equipped with the possibility to process the data from the camera, then use
Summa Cutter Control to do this.
Most software simply places the marks and sends the cut data to the cutter. They do not
have the ability to process the camera data. Summa Cutter Control will then process the
camera data in order to determine the position of the printed marks.

Some software is fully automatic and places the marks, sends data to the cutter and
processes the camera data.
Please refer to the user’s manual that came with your software or contact your software
dealer for details.

The camera images need to be processed by a computer. This means that a cutter with
camera option needs a dedicated Windows computer. Only one cutter with camera option
can be connected to this computer. This connection also has to be a USB connection. The
camera images cannot be transferred to the computer through an Ethernet connection.

The utility to process the camera data is integrated in the program Cutter Control.
Therefore, Summa Cutter Control needs to be initiated before doing OPOS jobs with the
cutter. If the program Cutter Control detects a cutter where the camera option is connected
to the computer, it will start up the camera module, so it is ready when the cutter will send
images to the computer that need to be processed.

S CLASS™ 2 cutter User’s Manual

Contour Cutting 3-20

3.5.2 Differences in calibrating OPOS CAM vs OPOS sensor

3.5.2.1 OPOS calibration

The OPOS calibration of a cutter with the OPOS CAM option is very similar to the OPOS
calibration of a cutter with an OPOS sensor.

1. Switch the cutter on and load black vinyl with white backing. Make sure Summa Cutter

Control is running on the computer that is connected to the cutter.

NOTE: Black vinyl with white backing MUST be used when calibrating OPOS.

2. Press Settings

3. Press More

4. Press OPOS.

The cutter will cut out two
squares, a little one inside a
big one. Afterwards it will
feed the media forwards.
“Weed out Rectangle” will
appear on the display.

5. Press Calibrate OPOS

6. Carefully weed the

rectangle, making sure the
small square stays on its

place. Press Back.

OPOS will register the position of the little square and calibrate itself accordingly.

3.5.2.2 OPOS media calibration

This option is not available in the menu on the cutter. The camera has to be calibrated with
the program Cutter Control. The cutter tools manual describes how to do this.

3.6 Cutting through

The cutting through functionality is focussed to cut simple shapes (e.g. rectangles). It is
most used in combination with contour cutting.
An interrupted cutting line makes sure that the material remains together thanks to the
small media ‘bridges’. When the job is finished the cut pieces can be torn loose.

FIG 3-3

3-3 FLEXCUT PRINCIPLE

Some cutting software can recognize the difference between a contour line and a cut­through line. The software first sends the data of the contour lines to the cutter and then
activates FlexCut, paneling mode and vector sorting and sends the cut-through data to the
cutter.
If the cutting software cannot do this, the user needs to send the data of the contour lines
separately, set the cutter in FlexCut mode manually and then send the cut-through data

Setting the parameters for cutting through the media:

1. Press Settings.

2. Press FlexCut.

3. Select the parameter to

change.

Press the arrows or use
Numpad to change the Full
pressure and press Apply to
confirm.

180 gr is a recommended
starting value for the full
(cut-through) pressure.

1mm is a recommended
starting value for the cutting
length at flex pressure.

The cutter will cut out a test pattern.

4. Check if the result is satisfactory. If not, change one of the above 4 parameters.

Reducing the velocity can also improve the result. It is never recommended to use
cutting speeds larger than 400mm/s (16 ips) with cutting pressures above 200 gr.

NOTE:

It is not always easy to find the correct balance between cutting deep
enough, making sure the pieces can be taken out easily, and not cutting too
deep, making sure the material keeps its strength while cutting. Sometimes this
balance doesn’t exist, which means that this material can’t be cut through with

satisfactory result.

NOTE: When cutting through, it is recommended that parallel lines are at least 1

cm away from each other. Otherwise, while cutting the second line, the first line

may come loose and cause trouble.

4.2.4 Cut Tests

Click Cut Tests to go to the internal test menu. Currently, there are two internal tests
available.

The DIN A4 test

The DIN A4 Test performs an electrical and mechanical test of the cutter in order to check
the cutting quality. It also provides feedback on knife setting, knife pressure, knife offset,
and cutting depth.
This cut is always run as a DIN A4 portrait/A-size image, regardless of the actual size of the
loaded media. If the loaded media is smaller than a DIN A4/A-size, a part of the outer box
will be clipped (not cut).

The confidence test

The confidence test performs a quick electrical and mechanical test of the cutter to make
sure that the cutter is fully operational. A media sheet of at least A3/B-size should be used
for this plot. This test is always cut at the left side of the loaded media.

4.2.5 Open file

Use this option to cut directly from the USB flash drive or to upgrade the cutter. Click on the
icon to see the list of the files that are present on the USB stick.

Select the file to cut, press apply

The cutter now cuts out the file. If the file has a new version of firmware, then the firmware is
upgraded. However, it is recommended to upgrade with the program Summa Cutter Control, if
possible.

4.2.6 Replot

Each job is stored in the cutter’s memory until a new job is sent. Pressing replot allows the
job to be replotted. After this button is pressed, the user can choose the number of replots.
The replot button does not work if there is no job in the memory or if the previous job was
larger than the cutter’s memory.

Press the Pouncing gap button, then change the pouncing gap to the desired distance.

Press to confirm or to cancel.

4.3.1.7 FlexCut

The FlexCut submenu is explained in section 3.5. However, setting up the cutter for
FlexCutting is not that easy. Follow the next procedure to try and determine usable FlexCut
settings.

1. Turn out the knife so that the protruding knife tip is longer than the material thickness.

2. Go to the knife pressure submenu (see section 2.2.2). Increase the knife pressure

gradually and perform the knife pressure test in between until the minimum knife
pressure to cut the material completely through is reached. Then increase this value
with 5-10%. Write down this value.

Apply

Cance l

NOTE:

The pouncing tool is not mounted in the machine at the same place than

the other tools. The pouncing tool should be mounted this way the center of the

pin is located above the black soft pouncing strip.

NOTE: Never turn the knife
so far out, that the media
can hit the knife shaft. Only
the knife edge should get in
contact with the media in

order to avoid media

crashes.

NOTE: It is discouraged to use brand new knives for cutting through. The

pressure setting and the knife depth of brand new knives change quickly. On

the tangential machines, a double tip knife or double wedge knife is

recommended for cutting through. This knife is more wear resistant and gives

and automatic overcut at the beginning and the end of cut lines.

NOTE: It is recommended to use cutting speeds of 400mm/s (16 ips) and lower
when the cutting pressure is 200gr or higher.

3. Turn the top piece of the knife holder half a turn counterclockwise. In the ‘knife

pressure’ menu, press the test to activate the knife-pressure-test-pattern. If the pattern
is still cut out completely, repeat these actions. Once the pattern is not cut anymore,
increase the knife depth (turning clockwise) with 1/8’s of a turn and perform the test
until the minimum required knife depth is reached. Now increase (clockwise) the knife
depth slightly: ¼ of a turn for a tangential knife and ½ of a turn for drag knives.

4. Decrease the knife pressure gradually and perform the knife depth test in between until

the knife pressure is set as described in section 2.2.2. Also write down this value.

5. Go to the FlexCut submenu and set full pressure to the pressure that was needed to cut

through the media. Set the Flex pressure to the normal pressure. Set the full pressure
length to 10mm and the Flex pressure length to 1mm. Then cut a test pattern.
Depending on the strength (size) of the ‘bridges’, go to step 6 or 7.

6. If the bridges are too strong, decrease the Flex pressure length and perform the test

again.

7. If the bridges are too weak, raise the Flex pressure length and perform the test again.

4.3.1.8 Advanced cutting

Overcut:

Use the Overcut submenu to generate an overcut in order to facilitate weeding the cut.
Each time the knife goes up or down, the cutter cuts a bit further then it should. Figure 4.3
below shows what overcut does with a tangential knife. A sample, cut out with a drag knife,
shows fewer overcuts because there are fewer up/downs (usually only one per curve/letter).
The overcut setting can be disabled (=0) or set to any value between 0(=off) and 10. One
unit is about 0.1 mm or 0.004 ".

Press to confirm or to cancel.

Panel size:

Use the Panel size submenu to set the size of the panel.
Press the Panel size button, then set it to the desired length.

Press to confirm or to cancel.

Panel replot:

This parameter determines if the design has to be cut more than once on top of itself and
panel per panel. Panel replot is used for thick media and media that is difficult to cut. The
value of this parameter is disregarded if paneling is deactivated. If this parameter is set at 0,
then the cutter will cut each panel only once. If it is set at 1, it will cut each panel twice.
Use the Panel replot submenu to set the number of times it needs to be recut.
Press the Panel replot button, then set it to the desired value.

Press to confirm or to cancel.

Sorting Vectors:

There are three options in this menu.

1. Off: When vector sorting is set off, the cutter will not optimize vectors. This is used when

the intelligence of the cutter driver is preferred.

2. Directional: If set to directional, the vectors are optimized for the cutting direction

(media movement). This is used when the cutting pressure needs to be set relatively
high (for example when cutting through).

3. Starting point: This option optimizes the starting point for closed curves. This is used

when the user notices the curves do not close as they should.

Press the Sorting vector button, then set it to the desired value.

Press to confirm or to cancel. Sorting vectors is default set to Off.

Long Vectors:

Some vinyls have the tendency to buckle when large designs (long vectors) are cut out. To
avoid this, the speed needs to be reduced. This option does this automatically, so the speed
and acceleration of small vectors are not affected when the speed is reduced.
Press the Long vectors button, then set it to Automatic or Constant velocity.

Press to confirm or to cancel. The velocity for long vectors is default set to
automatic.

TurboCut:

TurboCut increases throughput without raising the overall speed of the plotter by

speeding up the drag movement. The cutting time reduction is significant, especially when
cutting small, detailed designs. However, some thicker materials might not be cut properly
when this feature is activated.
Press the Long vectors button to set it On or Off.

Press to confirm or to cancel.

4.3.1.9 General

Media sensor:

The Media sensors detect whether media is loaded and also detect the end of the media.
The sensors prevent damage to the cutting strip and knife tip. The sensors can be activated
or deactivated with this menu.
When the sensors are activated, the cutter searches for the front end of the media during
the loading procedure. If it does not find it after returning the media for 1m (+/- 3 feet), it
stops returning the media and sets the origin in the X-axis.
The cutter will also stop during the loading procedure or while it is cutting if the rear sensor
detects the end of the media.
The cutter does not search for the front end of the media and assumes that the loaded
media is endless if the sensors are not activated.
Press the media sensor button, then select to activate (ON) or deactivate (OFF) both or only
the front sensor (FRONT OFF).

Press to confirm or to cancel. The default setting for the media sensors is ON.

Recut offset:

The Recut offset submenu is used to set or modify the distances between the jobs when
making multiple recuts.
Press the Recut offset button, then set it to the desired value.

Press to confirm or to cancel. The default value is 40mm.

The Cut off margin submenu is used to set or modify the distance the cutter will feed
before it will cut off the job when action ‘cut off’ is used from the software.
Press the Cut off margin and set it to the desired value.

Press to confirm or to cancel. The default value is 10mm.

Roll-up media:

The roll-up media submenu is used to choose when the cutter will start the automatic roll­up. There are 3 possible settings. Off, after job and after AUTO-panel.
Off disables the roll-up system. After job rolls up the media after the job, regardless the
number of panels the job contains. After AUTO panel rolls up the media each time a panel is
cut. The size of the panel can be set in the Panels menu or is 100 cm when paneling is set to
off.
Press the Roll-up media button and set it to the desired value.

Press to confirm or to cancel. The default value is after AUTO-panel.

Autoload:

The Autoload option enables the user to the change the unroll-procedure of the vinyl.
When autoload is on, the cutter will automatically unroll the vinyl, when needed. When the
autoload option is set off, the operator should manually unroll enough media before
starting to cut. When autoload is set to ask, then the cutter will pause after the pinch rollers
are put down. This gives the user the time to lower the pinch roller pressure, if necessary.
The default setting is ON. Tracking is not guaranteed when autoload is set to OFF.
Press the Autoload button, then choose to activate or deactivate the autoload feature.

Press to confirm or to cancel. Autoload is activated default.

Language:

This submenu is used to set or modify the dialogue language on the touch screen. When
the machine is new, it asks the user to choose a language. If this setting was set to the
wrong language, it can be changed with this option.
The information on the touch screen can be displayed in English, French, German, Spanish,
Italian, Polish or Dutch.
Press the Language button, and then set it to the desired language.

4.3.1.10 OPOS

The OPOS settings are explained in detail in section 3, except for the Alignment mode and
Monitor.

Alignment:

There are three additional alignment methods available on all S CLASS 2 cutters:
X-Alignment, XY-Alignment and XY-Adjustment. These alignment methods can be used if
the combination of mark color – media color cannot be read by the OPOS sensor.
These alignment methods require that the user registers marks manually, using the cutter’s
keypad. Most cutting software can put these marks around the printed graphic
automatically.

X-Alignment compensates for errors in media alignment by rotating the graphic’s contour.
This alignment method requires that the user specifies the origin and one point along the
X-Axis. X-Alignment is the easiest alignment method.

XY-Alignment compensates for errors in graphic rotation and skew. Skew errors occur when
the graphic’s X- and Y-axes are not perpendicular. This alignment method requires that the
origin and one point along both the X- and Y-axes are specified.

XY-Adjustment compensates for errors in graphic rotation, skew, and scale. Scale errors
occur when the graphic’s printed size is different from the graphic’s original size, as created
in the imaging software. X-Distance and Y-Distance parameters are required. These
parameters define the distance between the origin and the X-axis point, and between the
origin and Y-axis point. XY-Adjustment is the most accurate manual alignment method.

Monitor:

This option shows the read-out of the reflection of the OPOS sensor. The values can be
used to report a problem to a certified service technician.

cutter to the same computer is 6.2. The change in USB class becomes active only

after rebooting the cutter.

NOTE: The USB id in the cutting software needs to be the same as the chosen

USB id in the cutter. Each time a new USB is selected on the cutter and
connected for the first time to the computer, the wizard for installing a driver will

be started by Windows.

4.3.1.12 Length calibration

The option Length Calibration allows the length of the cut lines to be adjusted within the
specifications.
For instance, if a cut line needs to measure exactly 100mm, the cutter can be adjusted to
avoid any discrepancy.
The Length Calibration is explained in section 2.4.

4.3.1.13 Coil setup

This test is used to calibrate the knife and pen pressure and to set the knife and pen
“landing.”
The cut quality is seriously affected by incorrect landing settings. Before changing these
values, write them down, as there is no default setting for these parameters.
After adjustment, the value is saved in the system’s non-volatile RAM.

Press the button of the parameter that needs to be changed and use
to change the value of the highlighted parameter.

Press to leave the menu.

Setting the landing

The landing determines, among other things, the force at which the tool hits the media.
When calibrating the landing, the tool holder with the knife must be inserted in the head.
Make sure that the knife does not protrude.

Use to lower the landing value until the tool is in the “up” position. Then use

to raise the value of the parameter. With each change, always check if the tool is
completely down. Once the tool is completely down, raise the value back up three units.
This will become the proper setting.

4.3.1.14 Factory defaults

This option defaults all user parameters to factory default.

4.3.1.15 Copy current user

Press the button to copy the user parameters from the current user to all the other users. It

5 Maintenance and Cleaning

5.1 Introduction

The S CLASS 2 cutter range has a number of sliding surfaces made of smooth metals and
plastics. They are virtually friction-free and require no lubrication. They will, however, collect
dust and lint that may affect the cutter’s performance. Keep the cutter as clean as possible
by using a dust cover. When necessary, clean the unit with a soft cloth dampened with
isopropyl alcohol or mild detergent. Do not use abrasives.

5.1.1 Cleaning the drive system

Over time, the sleeves of the drive drum may become clogged with accumulated residue
from the media liner. This may cause the media to slip between the pinch rollers and the
drive sleeves, thus decreasing traction.

Cleaning the drive system:

1. Unplug the power cord.

2. Apply a mild solvent (normally used to remove old glue residue) on the yellow sleeves

and wait for it to dissolve the accumulated residue.

3. Clean with a brush (a toothbrush is recommended)

4. Repeat the procedure for all dirty drive sleeves.

5.1.2 Cleaning the media sensors

Over time, the media sensors may become dirty with accumulated residue from the media.
This may cause the cutter to malfunction.

Clean the media sensors by wiping them out with cotton swabs.

5.1.3 Cleaning the Y-Guide Rail

There are 4 areas on the Y-guide rail on which the tools carriage slides from left to right.
Two areas (1) are visible on the front side of the guide rail. The other 2 surfaces (2) are
situated on the back of the guide rail, directly behind the areas that are visible at the front.
Figure 5-4 below shows these areas. Although the shape of the Y-guide rail may differ from
model to model, the areas are located in the same place at the top and bottom of the
guiding.

FIG 5-2

5-2 SLIDING SURFACES ON Y-GUIDE RAIL

Over time, there may be some accumulated residue on these sliding surfaces and on the
rollers of the tool carriage.

Cleaning the sliding surfaces of the Y-Guide rail:

1. Switch off the machine.

2. Take a soft cloth dampened with isopropyl alcohol or mild detergent.

3. Clean the surfaces. When the tool carriage is in the way, push it gently to the left or

right.

5.1.4 Cleaning the nose piece (tangential machine only)

The nosepiece may accumulate residue from the vinyl that will result in poor cut quality.
The typical indication of a dirty nosepiece is an interruption of the cut line every 12mm
(0.5”).

Cleaning the nose piece:

1. Gently remove the knife by turning the knife holder counterclockwise.

2. Observe the orientation of the nosepiece and then push it out of its holder.

3. Remove any remaining vinyl residue using a brush or a pair of tweezers.

4. Replace the nosepiece.

5. Install the knife as described in section 1.7.2.1.
