We are using NEMA23 Steppers, KFlop/Kanalog, KmotionCNC. My problem is I'm losing .002 in the axis each time I perform a move. I set up a repeating Z move from 0 to -5. After a few moves it hits the limit.

I determined the amount it was off by homing the axis, them manually jogging it away from the limit, then back to the limit. Each time it hit the limit was a .002 to .003 difference.
