Hi, I just took delivery of my CNC xPRO v4 board and (apologies for hijacking the thread) I can't figure out how (or rather where) to connect a relay to turn my DeWalt router on and off (M3/M5). Am I missing something? I'm not familiar with these boards and am upgrading from a simple grbl shield mounted on an Arduino. I have scanned the wiki site but am stumped. I've attached an image of the type of relay I was planning to use if that helps at all. Any advice gratefully received.
