Why is it returning back to home?
It’s too high after Calibration
I think it’s returning to the camera calibration or camera capture position.
What have you done before?
Does this issue also appear if you directly print a gcode from the touchscreen?
The 1600mw laser does not sit directly on top of the material when cutting or engraving, it sits just above it. The calibration lets the machine know the thickness of your material, and then the head will retreat to the focus height. Not stay on the calibration height.
