Can you please give some advice on how to connect? I'm looking at the circuit diagram provided by Marco. I created a diagram based on what I currently have in my k40, and what I think might be the way I should connect, but I don't think either one is actually right. Everything was pretty straight froward following Marco's circuit diagram until I got to the part where I need to connect the PWM supply / mains power etc.
Can you please provide some advice? I really just want to get the laser to work so I can do some engraving, but I'm afraid I might destroy something if I connect it in the wrong way! Thank you.
