    @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?

              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?

                      So we can ignore the ones in your config.g file?

                          So you copied the lines from the config-override.g file and put them into your config.g file?

                          I assume you re-booted.

                              Strange problem you are having.

                              You posted a screen shot showing heaters Ex0, Ex1 and Ex3 faulted.

                              Were all three heating at the time?

                                M308 S1 P"20.temp0" Y"thermistor" T100000 B4725 C7.06e-8 A"Ex0"

                                On T0 you use a thermistor but not with the other tools?
                                What is your tuning command.

                                  @fcwilt Yes, all 3 faulted (nearly) simultaneously, when heating is initiated simultaneously

                                    @diy-o-sphere Changed to thermistor (actually changed hardware) just to try troubleshooting

                                        @kevinmar did you see my comment about retuning with a silicone sock in place, and my suggestion to reduce the M307 R parameter?

                                          If after re-tuning with the silicone sock on (if necessary) the heaters still fault, you can try reducing the M307 R parameter. Try a 30% reduction.

                                          I added the sock, retuned, and it still faulted.

                                          I reduced R from 2 to 1.5 and even to 1.0 and it didn't help
