    Spindle speed question -

    Today I installed the 3 phase motor, and started to calibrate the spindle index signal. The signal is within 25 rpm of the called for rpm from Mach3 - Does anybody know if this is close enough for accurate cnc threading?

    My ball screws came in today, so hopefully I will get those installed soon.

    Work has started on the turret changer based on the design posted elsewhere on this forum. I am using a hirth type of coupler instead of dowels however. Enclosed pics are of the progress.
