Ralph,
I will defer to Richard and the other ELS experts here to clarify this point, but I honestly don't see how it can be done accurately and with a good finish with one pulse per spindle rotation.
The mass of the spindle, chuck, and work would be a factor; the higher the mass, the greater the inertia and the more revolutions it would take to change speed, so the fewer pulses per revolution would be needed.? But I think it would be an issue with a mini-lathe with a low mass ER32 collet check, for example.
Let's see what Richard and our other ELS experts say...
