      M308 S2 P"21.temp0" Y"pt1000" T100000 B4725 C7.06e-8 A"Ex1"
      M308 S3 P"22.temp0" Y"pt1000" T100000 B4725 C7.06e-8 A"Ex2"
      M308 S4 P"23.temp0" Y"pt1000" T100000 B4725 C7.06e-8 A"Ex3"

      Not sure if these lines are wrong or not for one you have the T B C and A params not sure if they are needed or correct for a PT1000

      From the docs:

      Additional parameters for PT1000 sensors

      Rnnn Series resistor value. Leave blank to use the default for your board.
      Lnnn ADC low offset correction, default 0 (ignored if the hardware supports automatic ADC gain and offset calibration)
      Hnnn ADC high offset correction, default 0 (ignored if the hardware supports automatic ADC gain and offset calibration)

      Printers: A FT-5 with the 713 upgrade bits, a custom MarkForged style, a small Utilmaker style, a small CoreXY from kit and a E3D MS/TC setup. Various hotends. Using Duets (2 and 3) running 3.4.6

        yes but the T100000 is for a ntc100k thermistor should not be required for a pt1000 nor a beta value as they are linear and don't have a c param either so not sure if having those params are confusing the issue

          So Lnnn can offset the higher ambient reading?

            @fcwilt I'm currently re-running the autotuning with the removed T, B, and C values from the config

                  I was trying to point out that R, L and N are the only additional parameters for PT1000 devices.

                  The B,C and T are clearly incorrect but are the affecting the heater or are they ignored since they don't apply?

                  I don't know.

                      I agree neither do I know but it has to be worth a try

                        So Lnnn can offset the higher ambient reading?

                        I have no idea. Never used PT1000 devices.

                        And how does one know if the hardware supports automatic ADC gain and offset calibration?

                        Again I have no idea but I suspect @dc42 would.

                          @fcwilt I do use PT1000 and 100's as well and do prefer them and don't have any need for the additional Params as yet but we will see Hopefully Kevin gets it all sorted

                            Do those devices require additional hardware to connect to a Duet board?

                              pt1000 no but the pt100 does need the daughter board

                                    nor on a wifi/ethernet duet 2 board either just not quite as accurate due to the 4k7 sense resistor rather than the 2k2 one

                                        Did you check your config-override.g file to see if it included M307 commands?
