      @fcwilt Ambient is 26-30C

      Wow. I gather it is hot were you live and you have no air conditioning?

      I am not getting a fault readout in the console

      You posted this where you said there was a fault.

      The tuning runs fine, but when I paste the parameters into config.g, the resulting heater activation inevitably results in a fault before the tool reaches 120C, usually around 70-100C

        I think it's faulting way too liberally. My heater and PT1000 are working, it's not like I'm experiencing thermal runaway.
        Is there a way to change the sensitivity of the faults?

          What fault are you getting?

            @fcwilt Well, true ambient is about 24C, but the PT1000's always read about 27C as ambient.

            The heater faults, but there is no readout in the console.

              In what way does the heater fault?

                  What is happening that is evidence of a fault?

                          OK that helps.

                          All all three heaters actually active at the same time?

                          Do they all fault at the same time?

                          Can you take a screen shot of the temp graph showing the heaters as they heat up and then fault?

                            Your sensor settings a looking wrong...

                            Here is an example of mine
                            M308 S1 P"temp1" Y"pt1000" R2200 ; configure sensor 1 as PT1000 on pin temp1

                                  @kevinmar if you are running without a silicone sock on the heater block, please add a silicone sock and re-tune. Your M307 parameters suggest that the fan substantially cools the hot end, which typically means that the fan is blowing on the heater block.

                                  Also please confirm that the part cooling fan is off when you command heating and the heater faults

                                  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.

                                          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)

                                          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?
