DIY CO2 laser, MKS DLC 32 wiring 50w

Yeah… Sorry, once I get the setup clear I’ll make a proper diagram with my setup.

Yeah, the stop button is wird at NC to cut power but I don’t know what approach I’ll take… I dont know if I’ll use the stopt button to cut power or tu activate the reset function of the mks dlc32. The way it’s wired right now, the fuse/switch will cut all the incoming power.

I know, that’s why I only took the wiring from the A/V meter in that diagram, but I have removed it since I’m not implementing a potentiometer for now. As I mentioned, my intention is to control everything from the software.

And going back to the control wiring topic, I saw that you mentioned this thread in another discussion. I noticed that in the same thread, another person attached a diagram that worked for them:

and now I’m even more confused, it’s quite different from mine. It uses the G output of the spindle, which is used in other diagrams that opt for the use of a potentiometer. So, what is the correct way to wire that part (the TTL-S control)?
