I checked this at the beginning and it was fine...320 steps/ mm, 1600 micro steps on the stepper drive, 5mm / rev on the ballscrew.The same settings for all axis

Today I discovered that my VDF was set on CCW rotation and the cutter used for MDF was a right hand one. After changing to CW on MDF I get the right dimension.
However on the wood plate on a 40x40 square it's all perfect, but when I switched to a bigger 80x80 square I get again wrong dimensions 80x79.8.
Normally it should work also on a bigger square but at least half of the issue was solved.Last edited by cncnescu; 23-09-2018 at 12:09 PM.

With such a basic error as running your spindle backwards I suggest you run through all your settings and calculations again and check X, Y and Z travel in several areas with a dial guage to ensure your calibration and and other assumptions are correct.
You think that's too expensive? You're not a Model Engineer are you? :D
