If Start Z 0 and End Z is 10MM both positive, which way will the Z bed move? Down or up?
For lasers, Z0 is usually the surface of the material or the bed, and positive Z lifts away from it. GCode machines might not work this way, but the ‘Negative Z’ toggle in the Device Settings can be set to flip this.
ok, did not want laser to crash into material. I will give it a try.
