My Z probe works. It touches and then retracts showing 10.5 mm Z height. But when I start the cut, it never gets fully back down to the material. I think my error must be in the Processor G code somewhere. I am using the Beta 3. Can anybody suggest where in my Gcode file I can solve this error?

If the problem is this G92, what should it read?
