I recently bought a used cnc router and I've been going over the wiring and I noticed that a wire was severed and I can't figure out where it connects. I managed to trace all the other wires but I can't for the life of me figure out where this one wire goes. It is a Chinese machine and of course there are no manuals that I can locate online.
The BOB is a WEIHONG 6B-EX1D5. The wires I am referring to are connected to the BOB at the COM and CUT terminals on the bottom right corner of the board. But I don't know where these go from here. Can anyone please shed some light on what these wires help to control?
