This is my hal file for the spindle Don't matter what I do the spindle never spins smooth starts and stops as soon as any p,i,g are added even at .0001 seem to be to much It will spin at it max rpm if I set s to 10000 or more put and thing less I surges up and down bad Hoping someone can see something I can't The disk on the lathe spindle has a 125 hole disk with 1 hole index A b pickup I've tried the encoder.scale at 125 and at 500 nether change much
