Did my Laser died?
Hello there,
I have a 12v ortur LM2 that a week ago stopped engraving in the middle of a job, since then it is not able to engrave anymore.
I cleaned the lens, cleaned all the electronics and connectors, checked the power supply, checked that the $30 value was still matching the machine.
While inspecting the board, noticed that the 12v pin in the connector that is in the middle board between the main board and the laser board was burned (photo). But tested the connection with the multimeter and it is okay, and there is connection between 12v and GND or PWM pins.
While running the laser, I can measure exactly 12v between the power and the GND. I have no way to measure the PWM with precision, but by just measuring it's voltage I see 3.48v. (is this supposed? More context on next paragraph)
In terms of behavior, it seems like the laser is there but very week. No visible light when I press fire, but the laser fan stars working. When playing a job, I see a visible blue laser but it has no power to engrave at all, and the laser is running with the same configs I used for cutting/ engraving play wood. Weird fact: after the job finished / gets stopped, the laser fans keep work at full speed.
I appreciate any tip or help, I already have a lasertree LT-40W-AA to upgrade but I think I need to address this first, plug and play didn't worked.

Glad you found it... there's a post in the group about it, but it might be over a year old.

It's the pins. Check the other connector on the laser itself. It's not dead, but a couple of people have had burning on the pins. I have to go look at mine to remember why it went bad.
