Hi,
What kind of mill do you have? Are you driving it with steppers, or servos?
I'm in W. Bloomington. I had a knee mill retrofit with servos running Mach, but upgraded to a HAAS VMC. Also have a CO2 laser engraver run by Mach.
Not a whiz with Mach by a long shot, but I know enough to be dangerous!
shoot me a PM with your contact info.
