      Hello,
      I am running the Duet WiFi 2 on a cr-10s5 with the E3d Supervolcano hotend. I have the silicone sock installed and I have run the autotune function for this hotend. I run 12+ hour print files at work all the time, and a large portion of my prints pause themselves 1-2 hours from the end and throw a heater fault. By the time I arrive at work the next morning, the Duet has already abandoned the print, and the gcode log is so full of checksum errors I can't get to the original error. I have never once had a heater fault while I'm in the room. I need some help getting to the bottom of the issue.

          Ok, thanks for the tip, I enabled logging. I am curious if the faults are a result of the high filament flow rate going through the hotend. It is designed for ludicrous volumetric output and it delivers, however I tuned the PID's with it just sitting there, maybe the amount of cold filament running through affects the heating parameters?

            but the checksum errors might be something else.
            what firmware version are you running?

            dc says it might be a problem with the panel due connection.

              @veti I am running 2.0(RTOS) (2018-06-05b3).
              I do have a paneldue, I have researched this before and I never got conclusive results, so I just live with it.

                just disconnect the paneldue for a few prints and see if you still get the checksum errors.

                  If the super volcano uses a cartridge thermistor like the regular V6 hotend I would try gently wiggling the thermistor wires and see if you notice temperature changes. I had a couple of them go bad since I hadn't properly fastened the wires and the movement over time caused issues.

                  Needless to say I bought a couple of them and since fastening the wires from the heater cartridge and thermistor properly I haven't had an issue since with my normal V6 hotend.
