Are you planning to use a VFD and control spindle motor speed, or use a mechanical variable speed? If you have a 7i76 then using PWM seems a bit odd, as the 7i76 has a built-in digital potentiometer for spindle speed control. -- 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 Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
