      New parameters: M307 H2 R2.050 C309.100:130.600 D6.20 S1.00 V24.3 B0

      Another fault:

      (I had been using the fan to cool the hotend down, so ignore values before 11:00)

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

          @fcwilt it included M307 commands that were generated from the autotuning and saved using M500

            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

                                    Did the R value change much when you added the sock, or was it just the C values that changed?

                                      If you execute a M570 command from the DWC Console what value does it report?

                                        @dc42 C values changed when tuning with the sock.

                                        R values were a manual change
