LM3 has stopped working

Good morning, I have a problem with my LM3.
The laser immediately proved to be excellent and I carried out many jobs.
Tonight, while I was cutting 6mm plywood with the laser at 100%, the ortur lm3 suddenly stopped.
The laser is off and the light is solid red, with 3 beeps and 3 purple flashes continuously.
I tried turning the ortur off and on again, but the problem remains.
What can I do?
I await your advice.
Many thanks in advance.
Good work

This tends to be a Power supply error
I would suggest
a) Does the machine home normally or not even that?
if not unplug USB so you are sure you get only 24v power supply

b) what errrors do apear in console if above fails and you plug usb and are able to power on motherboard?

c) do a very detailed cable and connector inspections, specially near the motherboard. make sure all cables are fully seated

The problem was the power supply.
Thanks so much for your help

Great news!
