Couldn't resist. Small chunk of soft aluminum. Pass depth 0.001" to total 0.030". BROACH mode ON so no spindle turning. Set BEGIN/END positions. Used a Unimat DB200 cutoff tool set sideways and approximately on center.
So as long as you can disable the spindle out of speed detection and just not turn it on can't this also be done in LinuxCNC Lathe as a threading operation. Doesn't need the extra lines from Andy's G-Code. Still need to index and hold solid the spindle of course.
