            but when there are no target temperature this not happen.
            I checked, the board reset.
            I would also like to add than I didn't load filament, I put the temperature by hand.

                          What does your heater graph look like when you get the fault?
                          What shows up in the gcode console?

                            The graph start just ascend (like 10/20°c) and then the heater change to fault state and the graph start slowly getting down.
                            And I have nothing on the console, no error just the heater with "fault" under it.

                              @Phaedrux and with the beta4 the toolboard reboot when I get the error (so the temp is 2000°c for the graph)

                                β25/85 (K): 3800 ± 2%

                                I find this for the thermistor.

                                M308 S1 P"121.temp0" Y"thermistor" T500000 B3800
                                

                                so I put this, the temp is 12°c when it must be ~19 I think. I have always the fault, do you now what I nead to change ?

                                At low temperatures, high resistance thermistors like that one have poor resolution and accuracy. So your settings may well be correct. You may be able to reduce the displayed error by adjusting the H parameter in the M308 command for that sensor.

                                  Are you sure that you are running beta4 on the tool board? Use M115 B# (where # is the CAN address of the tool board to check). If you are, then after the tool board resets, please run M122 B# (where # is the CAN address again) and post the results here.

                                      Yes I read this on an other post in this forum, so I change this config with the default one in RRF configurator tool for my thermistor. Where there is a "C" param.

                                          the doc say:

                                          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)

                                          but I don't understand, do you have an example of use ?

                                            (the Heater 2 is not connected, it is just the heater 1)

                                            M308 S1 P"121.temp0" Y"thermistor" T500000 B3600 C1.196220e-7 H-7	; configure sensor 1 as thermistor on pin 121.temp0

                                            I modify the config, now at 20°C it return 20°C but je same fault accure after ~30°C..
