Duet 2 Wifi Blowing 15 Amp Fuse



  • Recently I have been printing alot and when I went to start a print and the heated bed heated up I noticed that there was smoke coming from the board and discovered that my 15 amp fuse was blown. This is strange because I can't find any reason for it to blow. Any help? Also, I noticed that the Power in and heatbed terminals were loose on the board, and when I wiggled the power in terminal, the board would lose power intermittently. Could this be the issue? Any help appreciated

    Assuming you mean the 15A bed heater fuse, you probably have a short in the bed heater itself or in the cable, for example because bed heater cable has chafed on something and worn the insulation away.
