      I was rerouting some wires adding a cable chain and during this process I think wires came loose because my part cooling fan and heat sink fan wouldn’t turn on when I fired up the machine again. If at some point things came lose and the fan wires shorted to each other or something, would that fry those outputs on the board? I checked for visual damage and saw none but I’m not getting any voltage on my meter from the “always on” output or the F0 output.

        @jasonpgr Depending on your board you may have a fan fuse.

          I believe I have the newest version of the duet WiFi. The board is about 8 months old. Where would I look for a fan fuse and what would it look like?

            If it's the version 1.03/1.04 board there would be a blade fuse right by the fan connectors.

              That did the trick, thanks so much! Pulling that fuse out was a bitch since it was in there so toght, but it did finally come loose and I swapped it out. Fans are cruising along now. Thanks again!
