I have a relay BOB that i bought off of ebay. i wanna use this board to turn my plasma torch on and off. So far I have enabled 1 output under pin 17 (the pin which controls this relay). How do i get mach3 to know that this pin should be controlled every time my G-code tells it plasma on/ off. I made my G-code using lazycam.... If anyone can help me out thanks!
