I'm not sure where to go with this. I've got a machine that's running pretty good right now, but I am about to put on a new solenoid valve operated pneumatic spindle brake. I'ld like to be able to set the brake and inhibit spindle start or program run, but still be able to jog the machine if I need to. I'ld like to add a mechanical push on / push off button to my control console to operate the brake. The electrical part is easy for me to figure out. I'm not sure how to configure Mach 3 to do it. I've got spare inputs on my breakout board.
I could just cut the input lead to the VFD with a relay, but that wouldn't prevent Mach from crashing a tool into a work piece if I forget to release the brake. I could add a really annoying sounder and a blinking light, but again it doesn't actually prevent a crash. My existing brake is tied to my E-stop switch, but I don't want to estop the machine for a tool change as it kills the job clock. The new brake is strong enough to allow me to do single spanner tool changes.
I know. I know. Beginner question right? LOL.
