My e stop circuit is hard wired to a master control relay not to Mach3 that controls all power to motors and relays and must be reset after Mach is running and the charge pump is receiving the signal. The master control relay also tells Mach3 through one of the pins that the e stop has been hit so it stops also.
How it operates.
Start computer and then start mach3. You must then press a reset button for the main control relay to close and latch in if the charge pump is receiving its signal.
If you hit an e stop or if the charge pump looses signal (like closing mach) the relay opens and all power is removed.
very similar to a "Start-Stop Circuit"
