About two weeks ago I had some major problems with my PLS6.60 (lost motherboard & Z axis sensor board) now when I manually move X or Y it moves .010" every time I press the buttons on the control panel & computer. It used to move .001" when I did this prior to the parts being replaced. I also updated the driver to the latest and greatest; can't seem to be able to go back to the old driver, the laser and the computer will not connect with the old driver. Tried changing the XY axis like the Z axis but it doesn't do anything. Does anyone have any suggestions? Been working with service but no solution has been reached yet so I thought someone else might have a different idea.
