I've tried on two progams, backplotted and all my code is correct, but the cut depth is wrong on every file I load. The DRO will say I'm cutting at a depth of -0.750 but it's only cutting a depth of -0.384 (example). What in the world am I doing wrong? To be sure I calibrated Z axis and it's right on the money.

Any help would be appreciated.

Set Z zero and the cutter to be the top surface of the work then run your Gcode file again. Assuming the cut depth is wrong then if the Z axis is jogged (or MDI) to zero does the cutter still touch the surface of the work ??

Tweakie.
