Hi Sir,
Joined the group as your post sticks out to me as I just purchased a SainSmart 5.5w laser to use. I have two 3d printers, one of which I have upgraded along the way. I now have an MKS Gen L V1.0 board and screen laying around and would like to utilize this. I will have to get a new PSU for this dedicated build, but at least I can get a 12v PSU in place of the dedicated 24v PSU I use for the printers…
From what I read on your post, looks as if I can simply change the PIN configuration in pins.h within Marlin to address the 5v pwm essentially? FYI, totally new to all of this, like I impulse bought this laser to use for some leather engraving and scoring to make accurate cuts…Not sure if you’re using grbl?
I still have a lot of reading to do to wrap my head around all of this. So, if I am totally off base, let me know, and I will keep digging!
Thanks,
Aron
