Am I correct in saying since this thread mentions VFD's it is for controlling an AC spindle motor?  I'm looking for direction on controlling a  DC spindle motor with Mach3.

Your assumption is correct.  Ac Motors only.

I have searched high and low trying to find out the basics needed to run a DC spindle motor from Mach3.  I am using a C10 breakout board - which I know will not support PWM.  If someone would give me a basic overview of what I need from a hardware standpoint I'd appreciate it.  Since Im already using up my parallel port, for the C10 board, Im thinking of using a RJ-45 breakout board.  Then, I'd go from the RJ-45 board to a DC motor controller to the DC motor.....would that work?

Hi,
Controlling the spindle speed has little to do with the motor type, ac,dc,brushless, etc, and everything to to with the motor controller driving spindle motor.
It is the motor controller that  determines how you will drive your spindle motor.

What motor controller do you have? If all you have is a DC motor, what are the motors specifications, that is what is the rated voltage and current for the motor?

Cheers,

Peter

Using a treadmill motor PM-DC, Model C3354B3008, 21.4 Amps, 2.6 HP max, 1.5 HP @ 95 volts DC continuous.  As far as controllers, I hope to use the MC-60 controller that came off the treadmill.  I am open to suggestions if you think I should us another controller.

Hi,

I don't have experience with this particular controller, but you may be able to get it to work.

I mainly use KB electronic controllers. The KBIC-125 below or similar should be suitable for your motor.

You could then use a DC-03 Digispeed to then control it from Mach3.
