Welcome

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

The S CLASS 2 cutters are made 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. So
you won't have to monitor your cuts, even when you're sending the long jobs through.

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 2 OPOSCAM series.
Minimum revisions needed for this manual:
Camera control: 2.3.0.0.
Firmware cutter : 006 (MD9981)
USB driver: 6.4

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 it is

available.

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

Before unpacking the cutter, make sure that there is enough space to assemble the stand
and to set the cutter aside 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 sits in front of the box. Behind the cutter is the box

containing the stand. The accessories are located at the bottom in a separate box.
Check first whether everything is present.

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

warranty.

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). Then insert left
and right two screws and turn them 3 turns in. Do not put a screw in at the front.

1.2 S CLASS 2 Cutter Components

1.2.1 The Cutter as viewed from the front

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 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.

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.

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

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

It has also holds the camera 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.

same type and rating of fuse.

4. USB port type A female: For plugging in a USB stick.

5. Ethernet port RJ45: For connecting the cutter to the LAN.

6. USB port Type B female: This interface is based on the standards specified in Universal

Serial Bus Specifications Revision 1.1. It allows a high-speed bi-directional
communication between the host computer and the cutter.

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

loading.

8. Roll media guide bushes: The two flange guides serve to keep the media roll in place

when media is pulled from the roll.

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

tracking. The SS160(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. Do not move the pinch roller
assemblies while holding them from this side only.

10. Screws to secure the cutter base: Screws (3 left and 3 right) hold the cutter base to its

stand. All the screws must be properly tightened before using the cutter.

11. Tubes for media basket: Tubes in the back and front hold the media basket. They can

easily pulled outwards to put the basket in its place.

12. Casters: The casters on the stand are equipped with locking brakes. Once the cutter has

been moved to its new location, press the brakes with your foot to lock the casters.

13. Media support rollers: Rotating support rollers for the media roll.

14. Media basket: The stand and linen media basket come as standard equipment with all

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

15 to 35° C

59 to 95° F

Storage temperature

-30 to 70° C

-22 to 158° F

Relative humidity

35 - 75 %, non condensing

35 - 75 %, non condensing

It is possible that the environmental conditions of the used media are stricter than those of
the machine itself. Please refer to the documentation about the used media.
Also make sure that the media has had time enough to acclimatize.

NOTE: Keep the cutter away from direct sunlight or a strong indoor light source.

The optical sensors in the machine may be affected thus causing unexpected

behavior of the cutter.

WARNING: There is a risk of injury from being caught or trapped in moving

machine parts.
Keep hands, hair, clothing and jewelry away from moving parts. Do not wear

jewelry, loose clothing, scarves or open jackets or shirtsleeves.

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 data first will remain active and
the other port will be deactivated.

NOTE:

The camera option functions only when the cutter is connected through

USB with a PC. There are no Mac or Linux drivers available for the camera.

If the cutter is connected to the computer with Ethernet connection only, then the camera
option will not work. It is possible to send cut data through the Ethernet port in
combination with using the camera option if the cutter is connected with the computer
with the USB cable. The cutting data itself can come from another computer.

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.

NOTE: The use of HUB’s or active extensions is not allowed.

The computer has to install three devices. A USB hub, the USB device driver for the cutter
and the USB device driver for the camera.

NOTE: The installation of the cutter driver and the camera driver must be
prepared by a running a program prior to connecting the cutter to the
computer.

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

rights and that UAC is deactivated or set to its lowest level (not applicable for
Windows XP or earlier versions).

2. Power off the cutter.

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

4. Choose to run Windows_autostart.

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

6. Click on “install USB driver camera”. Wait for the program to finish.

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

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

9. Power on the cutter (see section 1.4) and return to the computer.

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

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

11. Restart the computer.

S CLASS™ 2 cutter OPOSCAM User’s Manual

Setup 1-14

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 cutter is connected and switched on. After that the
program is run, the computer will detect a new device and install the correct

driver automatically.

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

is made so that 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 Check for interfering programs or hardware

Interference results in ‘green lines’ (when Camera control is started and when it is set in
color mode – see section 3.6):

The cause of this can either be software or hardware related.

S CLASS™ 2 cutter OPOSCAM User’s Manual

Setup 1-15

Other programs could interfere with the camera, it is recommended to check if such
programs are running. The procedure to check this is simple.
Double click on the ‘Safely Remove Hardware’ icon in the tray. Choose to stop the videology
device.

If the computer allows it, then disconnect and connect cutter again.
If the computer does not allow it, then check which program or service prevents this
(usually chat programs similar to windows messenger).

NOTE: power saving programs can also interfere with the proper working of the

camera and driver. For non-

laptop computers set power options to high

performance. For laptops make sure that the power suspend setting for USB is

disabled.

Hardware causes could be devices that are USB connected and that generate too much
traffic on the USB bus.
Examples are external hard disk, camera’s, USB adapters, …
Just disconnect each device separately and check if the lines disappear.

NOTE: Make sure the cutter is connected and switched on before camera

control is started. Also make sure that no other cutting software is running

before camera control is started.

NOTE: Close camera control before cutter is switched off

S CLASS™ 2 cutter OPOSCAM User’s Manual

Setup 1-16

1.5.2 Ethernet connection

A couple of parameters have 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 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 for 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 on forehand and need to be searched for, then follow procedure
below.

 Case DHCP server is used:

If there is no lease time set (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 IP address in 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

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

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

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

are no devices attached to the network that use IP addresses outside the new IP
pool range (use ping command for this – see Check IP).

If such devices are

found, then switch them off and back on after that the pool range is changed.

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

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

not work anymore.

When it was impossible to obtain an address with the above procedures, then there exist a
‘trick’ to try and find a free address. For that check the IP address and subnetmask from the
computer and chose an IP address that is ‘far’ from that 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:

Press simultaneously and . Type “Cmd” (without the “ “) and click on OK. Then
a program box opens. In this box type IP config.

Check if chosen IP address (xxx.xxx.xxx.xxx) is free:

Press simultaneously and . Type “Cmd” (without the “ “) and click on OK. Then
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, then this means that the IP address
is in use and cannot be used for the cutter. If there is no reply, then this address is free and
can be used for the cutter.

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 that 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 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 under 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, then the cutter will
immediately stop and after a second move the carriage to the right side.

S CLASS™ 2 cutter OPOSCAM User’s Manual

Setup 1-20

1.6.2 Pinch roller pressure setting

The S CLASS 2 cutters are equipped with selectable pinch wheel pressure. The pressure can
be set to “standard” or “low.” The
change in pressure can only be done when the pinch rollers are in the down position. When
reduced pressure is needed, then 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 it is switched on. On
the touch screen there will be a message, giving the user time to change the pressure on
the pinch rollers.

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

FIG 1-16

1-16 REDUCING PRESSURE

To work with reduced pressure do the following:

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

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

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

– see figure above.

3. Insert a loosened flange into one end of the media roll and tighten the knob. Verify that

the flange is secure. Then do the same on the other side of the roll.

4. Place the flange-equipped roll on the media supply rollers. Set the flanges inside the

groove of the flange guide. The flange guides can be moved laterally on the roller.

FIG 1-19

1-19 POSITION MEDIA FLANGE ON CUTTER

NOTE: If the flanges are not used (not recommended – tracking is not

FIG 1-20

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 on 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 are 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.

WARNING: Keep fingers and other body parts away from the cutting area.
There are hazardous moving parts.

8. Lower the pinch roller lever to press the media firmly against the drive sleeves. After

one second the tool carriage automatically moves from the right to the left to sense the
usable media width.

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 on, 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 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 being used.

The minimal loading procedure consists of:

 A media width measurement.
 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.

After that, the cutter is 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. It does this in steps and the length of the vinyl used is equal to a
number of times the measured width of the media.

IMPORTANT: Tracking of longer signs is only guaranteed when the full load

procedure is performed!

Full media load procedure:

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.

1.7 Tool Installation

WARNING: The S CLASS 2 cutters use razor-sharp knives. To avoid serious

injury, use caution when installing, removing or otherwise handling the knife!

1.7.1 Tangential knife installation

A knife has been pre-installed in your cutter. For safety reasons, the knife depth has been
set to zero. Simply turn out the knife (see fig FIG 1-23) 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. Underneath is the nosepiece.
Remove this part if another tool will be used in the cutter.

FIG 1-23

1-23 REMOVING THE TANGENTIAL KNIFE HOLDER

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

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

FIG 1-24

1-24 REMOVING KNIFE FROM THE TANGENTIAL KNIFE HOLDER

S CLASS™ 2 cutter OPOSCAM User’s Manual

Setup 1-29

 Installing the tangential knife and setting knife depth

1. Insert the standard knife blade into the knife holder. Make sure the knife blade is firmly

fixed in the holder. The knife is inserted correctly if it cannot be removed manually from
the knife holder. The installation tool can be used to apply enough pressure on the knife
to secure it.

FIG 1-25

1-25 BLADE ASSEMBLY

2. Insert the nosepiece from the side until it snaps into place. Gently insert the knife into

the tool shaft. Hold the nosepiece in place with one hand and, with the other hand, turn
the knife holder counterclockwise until the alignment pin fits into the small notch of the

NOTE:

The knife pressure can also be used to check the knife depth (which is
controlled by the amount the knife extends outs of the nosepiece). If the correct
knife pressure is raised b

y 150 gr, then the knife may not cut through the

backing of the vinyl. If it does, then 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

can be seen protruding from

the knife holder, and test 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.

2.2 How to Set Tool Parameters

The S CLASS 2 cutters can work with a knife, pen or pouncer. With the T version there is the
choice between drag knife and tangential knife.
Once a tool has been changed, then the tool parameters (menu settings) must be reset or
checked.
All the different tools have one parameter name in common: the pressure.
Each tool has also its specific parameters.
Tool parameters can be changed by either changing them in the current user, or simply by
changing 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.

2.2.3 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.

Rectangle 1 and 2 should weed out (remove) smoothly without sticking to the rest of the
vinyl.
The fan shaped pattern 3 should have a clear cut line in the middle; the ones at the sides
show burs.
The squares in 4 should be aligned and equal in size.
The 4 vertical cuts in 5 should be clear without any burs and straight all the way from top
to bottom (not rounded near the horizontal lines).

NOTE:

It is possible that not all test patterns come out perfect (depends on the
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 to the right, then 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 to the left, then 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 is like

decrease the value of the longitudinal parameter to correct the closing lines cut.

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

Each time a parameter is changed, press to perform the internal knife calibration test.

NOTE: Failing to set the knife parameters correctly will result in poor cut quality.

2.2.4 Changing drag knife offset

A very important parameter for a drag knife is the offset. The offset is the distance between
the knife center and the knife tip.

NOTE: Knife offset should be set each time the knife is changed and should be
checked if the knife shows signs of wear.

NOTE: Typical knife offset for Summa knives is between 0.41 and 0.45 for

standard knives, between 0.9 and 0.97 for sandblast knives and between 0.49

and 0.52 for the 60 degree knife.

2.3 How to Set 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 make changing speed fast and
easy.
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.

 Case media loaded:

3. Select new velocity,

scroll with arrows U/D first if
necessary.

 Case media not loaded:

2. Press on Settings

3. Press on Velocity

4. Select new velocity,

scroll with arrows U/D first 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 Long Vectors:).

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 is
dependent 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 media, and mount 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 on Settings

3. Press on More

4. Press on 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.

1 2

FIG 2-7

2-7 LENGTH CALIBRATION PATTERN

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

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

unit system (see :Panel Units).

3 OPOS (Optical POSitioning)

3.1 Introduction

Contour cutting is made possible by the highly accurate Optical Positioning System (OPOS)
with camera.

The OPOS camera, which is mounted in the tool carriage, registers printed marks that are
placed around the graphic. Because of this registration process, OPOS-CAM can determine
the exact position of the printed graphic.

Many versions of cutting software have the built-in capability to make contour cutting user­friendly and automatic.
Some software are fully automatic and take care of placing of the marks, sending data to the
cutter and processing the camera data.
Most software place the marks, send data to the cutter and use the utility Summa Camera
Control.
Please refer to the user’s manual that came with your software or contact your software
dealer for details.

3.2 Summa Camera Control

The program is used to process the
data from the camera. The program
should run in the background.
When the program is started, the
driver for the camera is also started.
This means that it is necessary to
power on the cutter before starting
the camera control program.
When the program is stopped, the
driver for the camera is stopped also
(this is the same as performing a save
removal).
Minimize the program after starting it
up. It will be minimized to the tray
and pop up when the marks are read
on the cutter.
The full explanation of the
possibilities of camera control are
explained in section 3.6

S CLASS™ 2 cutter OPOSCAM User’s Manual

Contour Cutting 3-2

3.3 Calibration of OPOS-CAM

To ensure that OPOS-CAM is working accurately, a calibration is necessary. The OPOS
calibration is the calibration of the distance between the knife tip and the sensor. After a
calibration, a reference test has to be done to check.

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

connected to the computer and the program camera control is running.

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

2. Set the head’s origin above a clean, blank part of the vinyl.

3.5 Automating Tasks with OPOS-CAM

OPOS-CAM allows the user to automate certain tasks, thus reducing user intervention and
production time. When cutting multiple graphics, the user only needs to move the OPOS
camera above the origin mark of the first graphic; cutting subsequent graphics do not
require additional user input.

There are two multiple-job situations in which contourcutting can be automated:

 When cutting multiple (copies of a) graphic(s) on the same media roll.
 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, then the automatic tasks also involve some
manual manipulation.

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

3.5.1 Cutting multiple copies of a graphic on the same roll

If the same graphic design has been printed on a roll with equal distance between the
different graphics, then this feature can be used.

First, load the media.

Cutting multiple copies of the same graphic on the same media roll:

1. Press on Settings

2. Press on More

3. Press on general

4. Press Recut offset.

5. Use arrows to change

the value. Then press apply.

3.6 Detailed Summa Camera Control Operation

The camera option cannot work without it being connected to the computer. If the cutting
software is not equipped with such a possibility, then the utility Summa Camera Control can
do this.
It is best to minimize camera control (to tray) after it has been started
It will then pop-up when necessary.
If the cutter is switched off for a long time, then it is advised to close the program, otherwise
the program will continuously try to start the video driver.
To do this, right click the camera control icon in the tray.

3.6.1 Main Window tabs

The program has 5 tabs, the first tab gives information about the connection with the
camera.

S CLASS™ 2 cutter OPOSCAM User’s Manual

Contour Cutting 3-9

The second tab is used to set the camera above the mark and check whether the system has
recognized it.

A green square will be visible around a mark if it is recognized as a mark.
The media in the cutter can be moved by clicking with the left button of the mouse in the
video area. If that is done, then the image (and media in the cutter) will be repositioned so
that the point that was clicked will come in the middle of the video area.
Otherwise said, clicking in the top half of the video area will move the media forward,
clicking in the left have of the video area will move the tool carriage to the left.
It is not necessary to get the mark in the middle of the video area, once it has been
recognized (green square around it) click ‘Apply’ and the rest of the marks will be registered
and the contours will be cut.

Contour Cutting 3-10

This is the view of the second tab when the camera is measuring the OPOS XY line. There
will be no green rectangle around the piece of the OPOSXY line if the size of the OPOS XY
line is not set correct.

S CLASS™ 2 cutter OPOSCAM User’s Manual

Contour Cutting 3-11

The third tab is used when the mark is not immediately recognized.
If no green rectangle was automatically drawn around the mark, then click on the third tab
(Mark Shape) and click on the button ‘Mark Shape’. A green square, slightly larger than the
mark will appear in the video area. Drag it with the mouse above the mark. This will force
the recognition of the mark. A window will be pop up given the user the chance to store the
mark shape (under a chosen name) so it can be used for recognizing the rest of the marks of
the job.
If the customer mark is not necessary any more, then the mark recognition can be set to
default again.

S CLASS™ 2 cutter OPOSCAM User’s Manual

Contour Cutting 3-12

The fourth tab is to store patterns which can interfere in the mark detection.
For this the camera has to set on a area on the media where there is nothing printed. Then
the pattern can be saved when ‘Media filter is clicked’ When the media filter is then chosen,
then the pattern is subtracted from the reading in order to get a clearer mark. This mode
can only be used in very special cases and probably will reduce the accuracy. It is usually
used to filter out shadows.

S CLASS™ 2 cutter OPOSCAM User’s Manual

Contour Cutting 3-13

The fifth tab is used to save images if a service technician asks for it. This can be useful for
troubleshooting problems over the phone.
You can also change camera settings, but it is not recommended to do this.

Mark Shape: With this an earlier saved mark
shape can be chosen.

Media Filter: With this an earlier saved mark

The program Camera Control does always its
calculation in black-white mode. If this option is
checked, then the user can see which the camera
takes in account for its calculations. This option
is checked by default after installation. The
program switches to color mode when setting
media Filter.
The color filters and threshold sliders can be
used to filter out colors or darker patches in the
media. If those sliders are used to try and get a
better image, then it is recommended to check
the black-white box so the user can see what the
computer actually calculates with. Settings of
the slider can be saved for future reference.

3.7 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 just are a guideline with useful recommendations and tips.

S CLASS™ 2 cutter OPOSCAM User’s Manual

Contour Cutting 3-16

3.7.1 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 s 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 3-17

3.7.2 OPOS XY

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

When OPOS XY is enabled, then the OPOS sensor will measure points along the extra line.
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 OPOSX. If the OPOS XY functionality is

needed, then the user must set change the setting ‘alignment mode’ in the
OPOS Setup to OPOS XY by hand 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 OPOS XY
feature of the cutter. If it is possible to define a line by hand in the design so that
it meets up to the specifications above, then the blocking of the software can be

neutralized by using the setting: ‘FORCE OPOS XY’ in the alignment mode.

The line may be added between or above the front Y marks. The distance between the
center of the marks and the line should not be more then 20mm( distance 1). The left and
right margin between line and mark should be 10mm for optimal sensing (distance 2). The
line itself should be 1mm thick. There should be at least 3mm white space above the line.

S CLASS™ 2 cutter OPOSCAM User’s Manual

Contour Cutting 3-18

3.7.3 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 must also be a front margin of 1 cm (3).

2

3

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

cutting the print off a roll (4).

S CLASS™ 2 cutter OPOSCAM User’s Manual

Contour Cutting 3-19

3.7.4 Orientation

Mining 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 that the cutter is ONLINE.
Click Cut from within the cutting software. The cutter should begin cutting the contour and
return to ONLINE status when finished.

1 2

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

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

orientation before starting to cut.

S CLASS™ 2 cutter OPOSCAM User’s Manual

Contour Cutting 3-20

3.7.5 Registering the marks

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

Most cutting software will initiate the special load procedure after sending the parameters.
If the software does not do this, then initiate the loading sequence from the cutter’s touch
panel.

Registering the marks:

Make sure the program
Summa Camera Control is
running on the computer.

1. Press Media size

2. Press Media alignment

3. Use the arrows

3.8 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 sends then first the data of the contour lines to the cutter, and
then it activates FlexCut, panelling mode and vector sorting and sends the data for cutting
through to the cutter.
If the cutting software cannot do this, then the user needs to first send the data of the
contour lines separate, set the cutter manually in FlexCut mode and then send the data for
cutting through.

Setting the parameters for cutting through the media:

1. Press on Settings.

2. Press on FlexCut.

3. Select parameter to

change.

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

180 gr is a recommended

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

Reducing the velocity can also improve the result. It is never recommended to use
cutting speeds larger then 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 it strength while cutting. Sometimes this
balance doesn’t exist meaning 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.

This menu bundles all the settings of the S CLASS 2 cutters. All settings in this section, apart
from the OPOS parameters, are user-dependent (information is contained within each of
the eight individual user settings, see section 2.1.5.).

4.3.1.1 Tool

The Tool submenu is used to change the default tool at power-up (same as in section 2-6,
but it can be changed when no media is loaded).

Press the Tool button, then press on the tool to another default tool. Press to confirm

or to cancel. After changing the tool, the cutter will ask the user to confirm that there

was a tool change just before it comes online if media is loaded (press on ).

4.3.1.7 FlexCut

The FlexCut submenu is explained in section 3.8., however setting up the cutter for
FlexCutting is not that easy. Follow next procedure to try and determine usable FlexCut
settings.

1. Turn out the knife so that the out coming 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 do in between the knife pressure test. Until the minimum knife pressure
to cut the material completely through is reached. Then increase this value with 5-10%.
Write this value down.

Apply

Cance l

NOTE:

The pouncing tool is not mounted in the machine on the same place the

other tools. The pouncing tool should be mounted so that 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 may get in
contact with the media in

order to avoid media

crashes.

NOTE:

It is discouraged to use brand new knives for cutting through. Pressure
setting and 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 cutting pressures is 200 gr or higher.

3. Turn the top piece of the knife holder a half turn counter clockwise. 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 tangential knife and ½ of a turn for drag knives.

4. Now decrease the knife pressure gradually and do in between the knife depth test until

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

5. Go to the flex cut sub menu and set full pressure to the pressure that was needed to cut

through the media and set 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’ got to step 6 or 7.

6. If the bridges are too strong, then decrease the flex pressure length and do the test

again.

7. If the bridges are too weak, raise the flex pressure length and do the test again.

4.3.1.8 Advanced cutting

Overcut:

Use 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 would
show fewer overcuts, since there would be 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 ".

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 there.
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 just

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 manually register marks using the cutter’s
keypad. Most cutting software can automatically put these marks around the printed
graphic.

X-Alignment compensates for errors in media alignment, by rotating the graphic’s contour.
This alignment method requires that the user specify the Origin and one point along the X­Axis. X-Alignment is the simplest 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 be 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 X-Axis point, and between the
Origin and Y-Axis point. XY-Adjustment is the most accurate manual alignment method.

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, 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 (toothbrush is recommended)

4. Repeat 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.

Two areas (1) are visible on the front side of the guide rail. The other 2 surfaces (2) are on the
back of the guide rail, directly behind the areas that are visible at the front.
Figure 5-4 below shows the areas. Even though 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 5-4

5-4 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 machine off.

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

3. Clean 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 1.7.1.
