Trying to figure out the wiring

You hoping to turn it on and off or control the RPM? If you hope to control the RPM I believe you will first have to setup an encoder on the spindle to get feedback to your computer.

I would like to do both. I thought mach3 will vary the speed once the min and max are input. Not as accurate as an encoder but should be close enough. I'm just interested in what to wire where to get started.

Interesting. I had picked up a relay to turn the spindle on and off but hadn't put any thought into letting mach3 control the RPM.
