Need Help Please Help!XC540 not cutting properly

as its position sensitive sounds like the main ribbon cable faulty it may have a separate one for the cutter if you are lucky may need just re-seating with this sort of fault and you go fiddling with it can have one of three outcomes .. you fix it .. stays the same .. don't work at all

 

Have had similar issues with my XC-540 but my cut contour is off by a much smaller margin. It worked fine until one day it didn't. It was not a case of an error that kept getting worse and worse.

I saw the voltage on my machine (section 4-9 of ROLAND SERVICE NOTES) was in error but the TOOL CARRIAGE BOARD COVER was brittle and I feared serious damage if I forced it while attempting to correct the voltage. My cut contour is fine if I do NOT use the crop marks function.

My remedy:
Print/cut without crop marks needs no correction. Printing and then cutting WITH crop marks goes awry.
I gathered info about the error of my cut line by several tests.
I printed a series of 3 black squares with a fat border and placed the cut contour on the inside of the squares. 3 squares only so I had several to look at/work with. Then measured the error in the cut line. Print again but adjust the cut contour by how much I measured the error. Repeat.
In my case I needed to "adjust" the cut contour by -.08" on the X value and +.047" on the Y value. When I need to print and allow to dry for a few days and then go back and cut, I use the crop marks and then set up a file of cut contours, only, and adjust them using these values and it works really well. -shouldn't have to do it but as I said, I fear greater damage pulling the tool carriage board cover off in order to adjust the voltage. If it ever gets to a point where even this doesn't work, I may have to call a technician for the proper repair(s).
Hope this helps.

 

You need a cut carriage cable.
