Update for everyone. I now have two working relays controlling the operation of the spindle motor via BOB and Parallel Port. I've also now successfully tested the G33.1 Rigid Tapping cycle with this setup.
Relay #1 is used to power on/off the motor controller board (MC2100). (M5 or S0 triggers off, M3 or M4 triggers on) Relay #2 is used to reverse the polarity of the spindle motor providing CCW operation. (M4 Triggers on, M3 or M5 triggers off) In order to get these functioning properly, I had to implement two different "timerdelay" functions in HAL. One delay is needed to allow the MC2100 board to power on and initialize before PWM signals are sent. The second delay is needed to slow down the reverse polarity relay in order to ensure the motor controller is properly powered off before allowing the relay to flip back to normal polarity. Otherwise the spindle would flip rotation to cw once triggered. HAL may not be the easiest to understand, but it can do some amazing work if you figure it out! Thanks for all the help on this thread!
