I've tried backlash compensation on and off. Have my CV settings at .1, no other CV boxes checked. Tried IJ mode absolute and incremental. Talked with CAM developer about all settings. Post is cutting with G2/G3.
I've played with motor settings. Tried cutting at 1IPM.... I'm stumped.
Pic shows what's going on. Black shape is what I'm trying to cut. Red shape is cut part measured on CMM. I'm always getting this deviation at around the 10 o'clock position no matter what I try. The toolpath is correct, I really believe it's something in mach3
