      Hi Skater, was anything connected to this board aside from the bed heater prior to this fault?

      Generally this is caused by a short circuit in one of the things connected to the Duet causing a failure on the Duet itself.

          When I remove the jumper from the INT 5v EN the heater will turn off. Does that help at all in the diagnostics? I would like to get this issue taken care of

            Its really hard to tell from the blurry photo, but looks like the E1 heater is also on?

            Could suggest the driver is damaged, but hard to say without a better picture tbh.

              Thank You
              That is correct. The E1 heater is also lit

                So how about a focused high res picture if there is anything else relevant we might spot?

                    given both the bed and E1 are stuck on, they trun off when you remove the 5v en jumper and removing the sd card makes no difference i would suspect the problem lies here even though there no clear visual signs of damage.

                    not to say its not possible I'm wrong or there is more damage; however determining what is wrong only help determining the likelihood of what caused the problem, which will affect how to handle it but thats up to the duet3d people for now.

                      Hello, sorry to see you've had a failure.

                      Please contact your vendor and initiate a warranty replacement. You can refer them to this thread.
