Graphtec plotter cutting undersize

[TheSignKid]

Seems that my graphtec is cutting 1/8th inch to 1/16th inch under exact size. any tips at what might be causing it.

in the direction the material feeds? might be time for a set of pinch rollers
also look for stretched belts, missing teeth or backlash

Also verify that "Job Size" in "Cut/Plot" menu is 100.0% and that "Fit to media" is unchecked.

GPGL Step size needs to be set to the same on the software and on the cutter. Default is 0.1mm, but I have found that too large for small objects. Recommend 0.025mm.

where in the cm4 software is this?

Down in the Cut/Plot page, and in the Default Job Properties. "Step Size" is written there.

Is there any good rule of thumb for which GP step size to work with?
Any pros/cons to running a smaller or larger one?

I have familiarized myself with where to set them on both my machine and Cutmaster software.

It is a Legacy thing. I am not sure why Graphtec still apply it on they cutters. computers and USB ports are fast enough to use 0.010. but the standard for most of the cutters is 0.025.
