Another remix - my spindle has a tiny 40T gear so this is needed to fit in under the pulleys. Reduced pulses per revolution but cheaper and quicker than trying to source a new spindle gear. Just #define ENCODER_STEPS to half of the value for the encoder used (2:1 reduction). The axle bore is a pilot size as I found it best to drill to size on the lathe to improve concentricity.
