    In an attempt to fix an electrical issue with this cutter I recently purchased and installed an upgrade kit (Part #4850901) that includes the backgauge control pad as well as the A4 circuit board. The machine powers on and functions correctly, except now when I make a cut the backgauge is almost exactly 0.25" off. For example; I set the cut depth to 17" and make a cut and it ends up being at 16.75".

    It also has an issue with the potentiometer that existed to a lesser degree before the electrical issue. I set the cut depth and (mostly when there's an impact on the cutting area, like jogging/stacking the paper) the backgauge will sporadically move to different depths :confused:

    Has anyone else experienced this potentiometer issue, and does anyone know of a way to manually adjust the backgauge or did something go awry when I was installing the upgrade kit?

    Thanks in advance for any advice!

    Thank you for the reply franco72! I actually got hold of a very knowledgeable technician who helped me solve both of my problems! I had to do a manual calibration of the backgauge, the steps are as follows:

    1. Set machine to 4 or 5" (doesn't really matter, something easy to measure)
    2. Make initial cut
    3. Measure actual cut for Step 7
    4. Press & hold Inch/CM button + press & hold #9 on keypad
    5. Release Inch/CM button
    6. Release #9 on keypad
    7. Keypad will start blinking
    8. Input measurement from Step 3
    9. Repeat steps 4 through 6
    10. Turn machine off & Back on
    11. Make another cut and measure
    12. Repeat process until your cut matches the depth you entered in step 1

    I was told that I can try spraying a little WD-40 around the potentiometer to see if that helps but I would most likely have to replace it. The part is around $80-$100 so I went ahead and ordered it, it's worth every penny!

    Do you have the # for the Tech? I'm having issues with mine.

    Thanks!

    I can't remember which company the tech I spoke with worked for but it was Hank or Bill at Graphic Equipment Specialists (804-379-2790) or one the the techs at MBM Corporation (800-223-2508), which is the company that sells and services Triumph cutters in the US.

    I hope this helps, my machine is still running perfectly!
