      I've just upgraded my Duet 2 to version 3.1.1 everything appears to be working except that the bed heater is not displaying on the Dashboard and my 7" Panel Duet (firmware v 1.24) is displaying all zeros

      Here is the config.g file heater section!Heaters.JPG
      Line 3 (M308 H0 C"bedheat") has also been tried with T0, T"Bed", T"bedheat" with no difference, Temperature panel on Dashboard shows three sensors :
      ext0, Extruder0, Extruder1

      Can anyone help?

        @CrazyJane according to https://duet3d.dozuki.com/Wiki/Gcode#Section_M308_Set_or_report_sensor_parameters for M308 S0, the P parameter must be the pin name.
        See at the end of M308 documentation old code - new code.

              @CrazyJane I would expect you must start bed heating with M303 to auto tune, then store them as to be used as M307 Parameters (or in override to be loaded with M501 later):

              https://duet3d.dozuki.com/Wiki/Tuning_the_heater_temperature_control in the section "All firmware versions" https://duet3d.dozuki.com/Wiki/Tuning_the_heater_temperature_control#Section_All_firmware_versions

                Hi,

                In your bed heater setup you are missing

                M140 H0 ; map heated bed to heater 0

                Which should appear before the M143.

                Now I don't know if this needs to be done or not but in my setup the M307 is after the M950.

                  @fcwilt Brilliant, worked first time, I don't know how I missed that. I can auto tune and refine everything else now. Thank you for your interest.

                    @JoergS5 the missing M140 line was the problem, everything is running now. Thanks for your help
