Title: Un-Wanted Shift of Y-Axis
Last edited by cincy-gearhead In 2023-2-16 10:44 Editor

Hello - I have a pretty simple rectangular profile I mill around the outside in about 8 steps, going down in Z 0.100 inch each step.  After the first pass, the Y Axis shifts about -0.010 inch for each step.  X axis seems ok.  I'm using incremental (G91) and not using any backlash (Para. #437 thru #445).  Help!
