I’ll describe the problem, and let folks digest the solution…
- Enter jog mode to set x/y/z, the machine homes and measures tool
- Use xyz to touch the tool to the workpiece and zero all
- Exit jog, but leave the tool in contact with the workpiece
…now you are stuck. You have no way to retract the tool other than to RUN your program and abort it, because re-entering jog causes the machine to re-home. However, instead of withdrawing Z first, Nomad will go full Y+ to begin homing and then Z+, dragging the tool across the face of the workpiece, ruining the workpiece at best, breaking the tool at worst. Luckily, I was working on plastic, so no tool harm.
So I guess the fix request is, if you enter jog at any time, go full Z+ BEFORE XY to home and not make assumptions about where the tool head is relative to the workpiece?
