So I was setting up a piece, and my fat belly hit the control joystick down button. I drove a bit 1/8" into my spoilboard. So I then rebooted, re-zeroed the machine. I went on to probe X,Y,Z with a Jenny bit.
File is a simple through cut with the jenny.
When I execute the file it’s cutting air, almost 14.9 mm above the surface.
I rebooted again, rezeroed machine. Probed X,Y,Z. Same thing, cutting air.
I’ve seen a couple cases on the forum where the Z axis was crashed into the workpiece resulting in a loose grub screw on the Z axis coupler, this video shows the process on the Y and X rails, Z is the same just more accessible (you don’t need to disassemble anything). I would start with verifying these first.
