Progress. Bergerda AC Servo driving the Spindle with a V belt still but at least driving it. MESA 7i92H PWM, small module from China for 0V-10V. S1000, F5 and M3 and M5 commands to start and stop.

Then cast some new pulley blanks and change to toothed belt. But for now it's so much quieter than the 2HP single phase motor.
