In mach 3, My rpm dro is inaccurate and varies greatly.
I know mach x pulsing driver was updated for faster bus computers,
Did it cause lower bus speed computers to have inaccurate rpm or inconsistency even
with single pules disk?
Even thou I have a mill, I'm interested in threading using both a 60 deg lathe
cutter in a holder mounted on the table as well as mill threading and turning
using 4 axis control.
as in these videos as examples

I would like to have the spindle rpm work right so the feed will
follow with rpm, If it's possible.
