Closed Loop steppers

Thanks, so what I need is a new pair of motors and a 3 axis driver kit to make this work properly?

Will flog the Vexta's off on ebay I think then. What size motor roughly do you think I will need for this machine?

No worries on making bits I have a 3,000 sq ft workshop filled with machines, so I am all good.

Measure up the lead on the X & Y axis and then we can determine the motor speed and torque required for an appropriate traverse rate. Suspect 3Nm motors will do the job as the existing motors are 2.5Nm at 250revs/min in a 60mm case. A newer motor will do the same in a 34mm case so there is room to move. The existing have a flatted 8mm output shaft, but the smaller motors may have a 6 or 6,35mm shaft so some work on the couplings may be needed. Its probably not possible to use the current X&Y motors as they are not spec'd independently of the matching controller.
