Hello all!
Running into an odd little problem. We are using a Maxnc-10 machine, converted controller using a Gecko G540 board and Mach 3 software. It seems that during a machine run, every time the Z axis makes a move, the Z axis moves up .0250. When it is supposed to descend, it doesn't. So the spindle is effectively rising up above the engraving area by .0250 every time there is a break between speed change but is not returning to the engraving area for the next move. It just continues to move up and not down.
Does anyone know what is causing this and how it can be corrected?
Appreciate any help!
Jeff
