Board: Cohesion3D Mini Laser Board
Problem/ Question: Since I’ve upgraded to the Cohesion board (and added an ammeter) I can’t get more than 10ma from my power supply. I thought the stock one was just garbage, so I bought a 50W Cloudray MYJG LPSU (110v) and still can’t get full power. Originally, I thought my tube was bad even with low hours on it. So I replaced it with a true 40W tube and the output is still 10ma.
Firing the laser with the button on the LPSU, through Lightburn and through the graphic control panel all produce the same results.
The potentiometer works because adjusting it lowers the laser power. The IN pin reads 5V when the laser fires. There is a potentiometer on the LPSU, but adjusting that seems to do nothing.
Does anybody have thoughts on where I should look to correct this issue? I’ve been pulling my hair out trying to figure this out and have completely rewired the machine, replaced the LPSU and the tube.
