      @auré Your bed (NTC 100k) and hot end (Semitec 104NT-4-R025H42G) temperature sensors are both thermistors, though slightly different. Both are supported by Duet and RepRapfirmware.

      Use these settings for your bed thermistor:

      M308 S0 P"temp0" Y"thermistor" T100000 B3950          ; configure sensor 0 as thermistor on pin temp0

      Settings for your hot end:

      M308 S1 P"temp1" Y"thermistor" T100000 B4725 C7.06e-8 ; configure sensor 1 as thermistor on pin temp1

      You can change to a PT100 or PT1000 if you want, see this page for a comparison of temperature sensors: https://duet3d.dozuki.com/Wiki/Temperature_sensors
      For a PT100 (which you don't have) you do need a daughterboard.

        @auré NTC 100K is a thermistor, NOT a PT100

            Hello, so I have this on my config.g but the toolboard don't see the thermistor 😕

            M308 S1 P"121.temp0" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin 121.temp0
            M950 H1 C"121.out0" T1 ; create nozzle heater output on 121.out0 and map it to sensor 1
            M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
            M143 H1 S280 ; set temperature limit for heater 1 to 280C

            I have chek the thermistor with a multimeter and it's ok

              I found this

              I change a command line with:

              M308 S1 P"121.temp0" Y"thermistor" T100000 B4725 C7.06e-8

              But don't work

                Can you send M115 and M115 B121 and confirm that the firmware version on both the mainboard and toolboard match?

                    @auré you're running out of sync firmware. Try running M997 B121

                    Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

                      Ok I send M997 B121:

                      update tool.jpg

                      The thermistore not work

                      I would like stop the fan and I have new error:

                        For the fan I found this post

                        I add F1:

                        M563 P0 D0 H1 F0 F1 ; define tool 0

                        And now the fan control work.

                        But not the thermistor.

                        I don't know why but now the thermistor on the toolboard work.....

                        I have only add F1

                            Looks like he is now.

                            Full config.g would be nice.

                                  G4 S1 ;wait for expansion boards to start

                                  can you try increasing the G4 S1 to G4 S4 to give it a bit longer for the toolboard to be ready?

                                    Yes thank you, I told myself that I had to extend the time because when I start the printer with DWC open, sometimes I have error communication of bus, but I forgot.
                                    I think you're right 4 second it's ok.
