As mentioned before, fitting a servo on the spindle as a spindle allows you to do this without messing with extra gears etc associated with two motors. All that is needed is to command a SwapAxis() in Machs VB to change from spindle to axis mode. I have servos on the spindles of all my machines, 12.5KW on the lathe, 8KW on the Beaver mill and 5KW on the Bridgeport..
