Re: [CAD_CAM_EDM_DRO] Homing position

Thanks. Thats what I wanted to know.

I will be repeating different parts on different days using jigs, so I want
to regain my setup as quickly as possible. I can't imagine trying to run a
cnc machine without home positions.

I am familiar with cnc mills and lathes, but was uncertain about the
tailstock on a manual machine. cnc lathes usually run the tailstock on a
separate slide so it's not in the way of Z travel.

Regards
Roland
