I wired my VIN backwards ...
-
As the title says, I wired the VIN backwards on a Duet 3 6HC. The fuse didn't blow, and now I've wired everything up the righr way I've got nothing at all, no lights, no evidence of any power at all. Is there anytyhing I can do? I'm devastated by my own stupidity!

@ben-0 Does it say anything when connected over USB?
-
@chrishamm OMG, it does! Everything lights up and the paneldue even powers on.
I've checked the voltage to the VIN and there is 24v going into it, so I didn't blow a fure in the power supply or anything, sadly
-
Sounds like it's the 5v regulator that was damaged. You could supply 5v via USB or from a separate power supply or buck converter.
-
@phaedrux I just did that, 24v through my normal power supply and 5v through a USB charger connectyed to the same circuit. Power supply is now fried and blows the house fuse when plugged in. Today is going from bad to worse!
