Hello Andy, Didn't try rigid tapping but the Mazak has the encoder coupled to the spindle by means of a timing belt in a 1:1 ratio. So, unless the motor in that machine is coupled in a synchronized way to the spindle you'll always have the chance of missing synchronization. Also ,as you pointed out, if the ratio is not exactly 1:1 you'll eventually have deviation as the spindle turns (assuming this is a 1 PPR configuration).
