This is my first attempt in making a laser engraver and I’ve got an issue connecting my 20w laser diode to my sainsmart GRBL USB driver controller board.
The laser diode has three pin connector with wires from it, PWM, GND and 12v +. But on my control board I have: laser 2 pin and TTL 2 pin.
My question is how do I connect them?
Thanks in advance
