Problem 5v on duet 3 mini 5 +
-
Hello, i have a problem with my duet 3 mini5+ card, it worked fine for 10 or 20 mins. But now i can only connect to it when it's powered with usb. When i try with VIN power only 2 led light up (V_FUSED and 12V+ ).

@azariel sounds like you've shorted the 5v rail somehow
was anything plugged in or unplugged while powered?
Are any components getting hot to the touch when powered by 12/24v only? -
@azariel I don't know about that specific board, but on other Duet boards, there is an on-board jumper that connect 5V to the board. The jumper is removed when it's powered by a USB port. Is the jumper in place?
If it was never removed, it's possible that the USB 5V backfed into the onboard 5V regulator and damaged it.

Everything was plugged, i read it could be a wrong wiring with the bl touch that shorted something but i checked and it seem correct. Nothing is hot.

@azariel definitely sounds like a short.
Might be a good idea to post some high res photos of the board -
here are some photos
