Re: [CAD_CAM_EDM_DRO] cnc lathe - threading - alternitive method?????

We thread with TurboCNC using G33 and a custom G76 routine we added to
it. Both work well, but G76 is canned thus much faster to program.

The spindle needs to generate a sync signal because the start of the
thread must be timed to the spindle position.

I think it could be done, has anyone tried this, or have a theory on how it could be done????
