      Looks like i blew the fet on the fan 2. https://imgur.com/a/2aRFj6S anyone know what the part number is and if its the only thing that would blow? I accidentally shorted the pins.

        Shorting fan pins blows the mosfet, and may also blow the 1A fuse (on Duet revision 1.03 or later) or the trace linking VIN to the VIN side of the fan voltage jumper selector block. If the fan still works when you plug it into one of the always-on outputs, then only the mosfet is blown.

        There is a wiki page giving spare part numbers.
