Hi all, I’m retrofitting my old mach 3 cnc with the mach4 pro controller kit. I have a vacuum pump and would like to control it with an on screen button signaling the aux2 port, if possible.
I ran the 12v and ground on the aux2 to the relay at my pump, it works but the pump turns on immediately when the control box power is turned on.
Can i change the power on that port to default off, and make a button to turn it on in mach 4?
Thanks for any help. If this can’t work, any other ideas?
