Chris,
That sounds almost identical to my setup. 2-1 belt drive ratio via
timing belts, max RPM is 6k with motor spinning max 12k. Encoder on the
motors shaft and the guys helped me mask one of the index pulses to make it
work for rigid tapping. I think my encoder was 500 line but I am not
sure....
