Hi. I am finishing up a 4 axis CNC router table. I wanted to turn my spindal (router) on and off. I could not find anything to set the spindle on a simple IO line like the sptepper motors, etc. I do not want to use a PWM, etc, just on/off remotely using the program. I do not have speed control. Just want to pull in a relay. I have a relay board that will pull in with a simple TTL input from the parallel card, just not sure how to set it up. I am assuming this is fairly easy, just need some help doing this?
Thanks,
Charlie
