Roll Cutter Accessories

Roll Extension

Bolt the two plates to the right side of each panel. Do not attach the plates both to the inside or both to the outside of the side panels.

Just-In-Time Light Sensor

Clamp the sensor assembly onto the front lower bar. Adjust the angle so the carriage can move without touching the sensor and so that paper exiting will pass between the two prongs. Attach the connector with the black wire to GND on the sensor. If you purchased the sensor after getting your machine: open up the controller; attach the cable so the black wire is at H6 (connecting 3 of the 4 pins); reassemble the controller. To activate the sensor, step to the Sensor menu and use the arrow buttons to select the JIT sensor. Place a piece of paper between the prongs to verify that the display changes to "Blocked". If the sensor is not responding first try any thicker material. If the paper is too thin, apply a small piece of tape over one prog to reduce the light beam intensity. Then, at the Count menu set a quantity of sheets to cut and press the checkmark button. The cutter will stop after each sheet and resume when the sheet is removed. To turn the sensor off step to the Sensor menu and use the arrow buttons to select Off.

Just-In-Time Switch Sensor

Clamp the sensor assembly onto the front lower bar. Adjust the angle so the carriage can move without touching the sensor and so that paper exiting will pass between the metal plate and the spring wire. If you purchased the sensor after getting your machine: open up the controller; attach the cable to the two pins nearest H6 (connecting 2 of the 4 pins); reassemble the controller. The 3-pin connector goes to the sensor assembly - polarity does not matter. To activate the sensor, step to the Sensor menu and use the arrow buttons to select the JIT-S sensor. Place a piece of paper between the prongs to verify that the display changes to "Open". Then, at the Count menu set a quantity of sheets to cut and press the checkmark button. The cutter will stop after each sheet and resume when the sheet is removed. To adjust the spring wire grab the 1/8" steel bar with a pliers and turn it so the spring wire gently touches the metalized surface. Note that the spring wires can be rotated counter-clockwise on the steel bar but not clockwise. The yellow tape prevents the roll material catching on the gap in the contact surface - if needed replace with 1/2" scotch tape. Also note that a second spring wire attached to one of the screws must contact the steel bar to complete the circuit. You may need to setup support for the output sheet (e.g. a stack of books, etc) so that the cut sheet stays in the switch sensor. To turn the sensor off step to the Sensor menu and use the arrow buttons to select Off.

Mark Sensor

The MARK sensor uses a color sensor to detect printed registration marks on your roll material, allowing the cutter to automatically locate and cut at each mark (for posters, film packaging, brochures, etc.) Clamp the sensor assembly onto the front lower bar so that the center of the sensor is looking down where the mark will appear along the left edge. If you purchased the sensor after getting your machine: open up the controller; attach the cable so the black wire is at H6 (connecting all 4 pins); (at the sensor black goes to GND and covers 4 of 7 pins) reassemble the controller. Step to the Sensor menu and use the arrow buttons to select "MARK". Press the checkmark button to enter the Mark settings submenu:

• ON-MRK? — Position the material so the sensor is over a printed mark, then press the checkmark button to capture and save the value under target ambient lighting.
• OFF-MRK? — Position the material over a blank area, then press the checkmark button to capture and save the value under target ambient lighting.
• BACK — Distance the feed retracts before the first cut if you don't want the mark to appear on the sheet. Set to 0 if you want the mark to show.
• FORWARD — Distance the cutter advances forward after the first cut if you don't want the mark to appear on the sheet. Set to 0 if you want to mark to show.
• SEARCH — Speed at which the paper advances while looking for a mark. Lower is more reliable; higher is faster. Range 1–20.
• TIMEOUT — How far the cutter will advance (in units) before giving up if no mark is found. Typically 1 to 5 inches.
• GAIN — Sensor light sensitivity: 1×, 4×, 16×, or 60×. Start at 1× (lowest). Increase if marks are faint or the contrast between mark and background is low.

After configuring the settings, set a cut quantity at the Count menu and press the checkmark button. The cutter will advance and slow down before getting to the mark. It will then make 1 or 2 cuts near the mark. To turn the sensor off step to the Sensor menu and use the arrow buttons to select Off.

Thin Material Support Bar

Locate the two clamps with small holes at the end opposite the clamp (the outer pair shown below). Slide the provided 6mm smooth rod ends into each clamp. Attach the assembly to the front lower bar so that the rod top surface is on level with the square aluminum bars and about 13” apart. The purpose of the bar is to reduce the tendency of thin flexible material to sag between the O-rings and the hold-down aluminum bars. Gently tighten the screws. The photo below shows the setup from the front of the machine with the aluminum bars removed for clarity.

Gravity Feed Guide

The gravity feed guide is comprised of two short arc shaped clamps (the inner pair shown above) to guide very flexible materials. Attach them onto the front lower bar, about 6" apart with the convex side on top and the free end touching the square aluminum bar (the bar is not shown above). This helps guide the film away from the cutter and over the table edge for gravity feed into a bin.

Brake

Mount all brake components onto the rear lower fixed bar. The round flange goes inside the torsion spring. The two large clamps go on opposite sides of the spring. The long bar presses against the material roll to decelerate the roll faster and avoid overshoot. To increase friction lift the small arm up and tighten the clamp screw to lock the position. The two small clamps constrain the position of all components on the fixed bar. With brake pressure you should be able to increase acceleration / speed. For heavy rolls and/or heavy brake pressure, you might need the larger motor if your model has the smaller stepper - see the Accessory page on the website.

Large Motor

To switch switch from the small feed motor to the large one: First disconnect power. Detach the wire to the motor by pulling on the connector (not the wires). Unbolt the motor and install the larger one in its place. Remove the 4 screws holding the controller box and the 2 screws holding the PCB. Remove the cable that went to the small motor and relace it with the provided cable with the 4 small windows pointing to the center of the PCB - make sure all 4 pins are engaged. Screw the PCB back to the enclosure and the enclosure to the frame side. Attach the connectors matching up the red wires. Attach power and turn on. Go to menu Gear and enter 5. In the Console Commands section below follow the section on adjusting length.

Controller circuit board

Removal:

1. Remove the power cord from the controller.

2. Remove the 4 screws on the controller box.

3. For 2025 models: remove 2 screws holding the PCB and gently slide the PCB with button panel out of the box.
4. For 2026 models: gently slide the controller box away from the chassis and remove the 3 screws holding the PCB to the chassis.
5. Disconnect the motor connectors.
6. Disconnect the button panel from the PCB.

Replacement:

1. Connect the button panel to the new PCB - be careful to align all 12 pins.

2. Connect the wire from the upper stepper to the X pins (J4). Make sure the small windows on the connector point left and all 4 pins are engaged.

3. Connect the wire from the lower stepper to the Y pins (J3) similarly.

4. For 2025 models: slide the PCB with the button panel into the box and screw to box to the chassis.

5. For 2026 models: screw the PCB to the chassis with the L shaped plastic spacer and screw the enclosure over the PCBs to the chassis.
6. Do a test cut of one inch to verify the motors are working and moving in the right direction. If not, use the Hardware menu to change the motor direction (or turn off power and reverse the associated connector).
