      This is a Duetwifi2 with the extension board in an E3D Toolchanger. I just did a rebuild of a tool (a V6 with an orbiter feeder) powered up and all looked OK. I went to power the new heater and I hear a "tick" from the board and the panel due goes dead. No web access either. All the fans are working and the blue LED on the board is lit.

      So... what to test? Ideas? Did my Duetwifi just croak on me?

        Power everything off. Inspect your wiring for shorts.

        Then follow this guide.

          @phaedrux Yup I blew the 7.5a fuse in the extension board. There has to be a short in the heater cables.
