Hi
Iam new to the forum. Hope someone can help me. Having recently finished building my CNC. All appeared OK until I measured my shapes. They are all smaller than designed appr 2mm regardless of size. The shape is correct.I use fusion 360. Have checked the design over a few times but all looks OK. I suspect it is to do with a setting in linuxcnc. Any suggestions would be welcome.

Are you certain your scaling is correct?
Are you sure you are not loosing steps?
Do you have a backlash issue?
