Thank you John and Andy. I've got my machine working almost exactly the way I want: When my spindle is enabled/disabled I have a oneshot triggering a port pin connected to a modified wireless remote for my vacuum system.
Now I just need to build a workaround for the ~4 s pulse I get on that port pin when the computer is turned on... I'm guessing I need to wire in a delay-on-make lockout for the vacuum remote connection that triggers on some output on the computer. N.C.
