        duet wifi 2 - firmware 3.4.0

      Problem - multiple heater faults
      extruder temp goes above set temp from slicer and keeps climbing until a heater fault occurs.

      Sometimes the temperature is correct and stats to print and during print a heater fault occurs. The 3D print surface indicates that the model is being printed much higher then what it should be.

        @blitzreg Sounds like a faulty HeaterCore, contact E3D for replacement.

          @blitzreg Run a M303 T0 S300 to calibrate the heater and remember to configure the thermistor

            Can you send a picture of the graph?
            I had a similar problem with 3 heaters with the same batch number.
