Hi Ben
How did you tune the motor? You should get more than 70 ipm. Check here for Mach3 set up:
http://www.kelinginc.net/Mach3Tutorial.doc
• The step resolution of the motor drive, if you set at 8
• The thread pitch of the screw. (How far the table moves with each rotation
of the screw) let us say it has a 5TPI pitch.
So Step per should be 200 x 8 x 5 = 8000.
