I’ve been testing this: X and Y off by 1%
Had an issue where the cut was off by about 7mm near the edges on the X axis which really screwed my project up. When testing I was seeing a skew up to 10mm, but after modifying the machine, frame, and tuning I got it down to 2mm. Have some more work to do before I can run another cut and test with a real example, but I’m optimistic.
