Any one using a Pokeys 57e and m16 to drive an AC servo driven spindle ? I cant get my spindle to sync with Z axis of my Lathe . I'm using a Lichuan motor but would be interested in and info if it was an AC servo motor . Been fighting this problem for six months , went through several brands of controllers. I have control over the motor as far as speed and direction . But cant get it to sync . Don't know if its a Mach4 problem or a configuration issue .Any help would be greatly appreciated thank you all.
