[solved]

it's 20000 steps per unit. pulled this out of my old mach3 xml config file

My next issue on this industrial hobbies uc300 upgrade...
(I'll do a write-up here when it's complete)

Does anyone happen to know the pitch of the ball screws on the x y and z axes for these IH/RF mills?
The encoders are us digital E2-1000 so they are sending 1k pulses per revolution.
I have no idea what the ball screw pitch is though so no way to calibrate the units in software.

Thanks
