It is only connected to the A command at all so that I can jog it to tweak the phase relationship if I ever need to re-cut a gear. > But ultimately what does the G-Code look like for hobbing that gear? It's just a G1 Xnnn move to feed the gear through the hob. The hob moves at spindle/teeth time all the time. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
