hi , im getting ready to use mach3 and pmdx breakout board on waterjet , setup process already started , but am confused on 1 thing ,i need 2 screen buttons on screen to turn water on/off and abrasive on/off . i can get buttons and leds like i need but how do i associate them with a m-code to send output signal to board to activate relays as needed , also need to be able to use button on screen manually .
thanks
