Re: Inaccurate 2D Contour cuts
I want to say that some mechanical coupling could be loose but if the error is consistent over time by 1/32", that tells me that it could be configuration with your STEPS PER UNIT (SPU) configuration for both X and Y axis. If this is a Rack & Pinion machine, it's most likely that PINIONS on both axis have equal wear over time, causing the originally configured SPU to be off. You could do 1 of 2 things:
1. Re-calibrate the machine based on new measurements and update the SPU for both X and Y
2. Identify and purchase new pinions are each axis and leave the SPU setting untouched
