OK, I'll try to make it as clear as I can:
laser unit has two sets of black and red wires going to two plugs in the laser controller board. above each of those input plugs are out put plugs, one is for the cooling fan and the other is for the laser which has a resistor attached across the wires.
on my CNC Shield board, where do I plug in the fan wires and where do I plug the laser to??
I have read two possible locations.
- into the Z+ pins for the laser and the fan in to the 5v/grnd pins
- the laser into the spindle control pins
So, where do I plug these two wires into to get the laser to work?
