I have a question about the power output of the fans on Duet Wifi.
My board is connected to a 24V power supply, what type of fan do I use to connect to my board, 5V, 12V or 24V?
@neithart I have the same problem as you, I accidentally caused a short circuit in fan1. The board is not recognized, all LEDs except the 3.3 V are lit, Wifi does not work and whem power board HeatBed Hotends Start heating.
It looks like it burned U2, there are two black dots on the CHIP.
You could solve the problem?
