G0704 Rigid Tapping - Servo Spindle + Mach 3

This is done by putting the A axis and spindle step/dir pins on same output port/pins for servo spindle control. Not using SwapAxis. It is setup in the motor tuning so F100 = 100rpm. For example G01 Z-1 A-20 F500 will turn the spindle 500 rpm for 20 rotations while moving the Z down 1 inch.(which would send a 1/4-20 tap 1 inch deep at 500 rpm). Probably not the best or correct way to do this, but it works. Code - G0 X0. Y0. Z0.1 G1 Z-0.6 A-14 F100 G4 P0.2 G1 Z0.1 A0 F200 G0 Z0.5 Disclaimer: Use at your own risk!!!!! It's not my fault or problem if you crash or break your machine.
