I'm running my AC Servo spindle motor as step/dir and can easily tell LCNC to do 1 RPM. I also have the quadrature encoder on it so I can do power tapping. The drive is through the MESA 7i92H as one of the stepper channels as is the encoder signals. Is there a way to tell the spindle to turn until it finds the index and stop so it's always stopping at the exact same spot? Like decelerate to 0.5 rev per second (30 RPM) or slower and stop when the index happens? With either an M5 or the button on the user interface? I currently have acceleration/deceleration set high so it reverses quickly with power tapping. Not to mention the ratio from motor to spindle isn't quite 1:1 because I didn't turn the pulleys exactly the same diameter or groove depth. But on an M5 a deceleration to 30 RPM and then a complete stop on the index edge. Thanks John
