Specs on the rotary encoder. 3=Quadrature with index 25=0.25" bore 127=127 pulse/rev Probably wayyyyy too coarse. Apparently super Z axis accuracy wasn't real important on this mill back in 1990.
All three ball screws are 5 TPI. On 3/31/2014 7:22 AM, Dave Cole wrote: > The scales should not be a problem.
