      are those OK

        Have you edited also the homeall.g?
        You have to change the M98 for calling the macros for deploy and retract...

                  your thermistors are configured wrong. that is the default and incorrect for your thermistors.

                      Ok, i change the Config.g

                      but the thermistors shows the Temp. right.

                      i use the PT100 Thermistors

                        that is in no way reflected in your config.

                                  And where do you call the G30?
                                  It's not incuded in the homeall.g

                                    PT 100 would be configured like this (change the spi to match the correct terminal)

                                    M308 S0 P"spi.cs1" Y"rtd-max31865" ; configure sensor 0 as thermocouple via CS pin spi.cs1

                                    M143 H0 S120 ; set temperature limit for heater 0 to 120C
                                    M307 H0 B0 S1.00 ; disable bang-bang mode for the nozzle heater and set PWM limit
                                    M308 S1 P"spi.cs2" Y"rtd-max31865" ; configure sensor 1 as thermocouple via CS pin spi.cs2
                                    M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1
                                    M143 H1 S280 ; set temperature limit for heater 1 to 280C
                                    M307 H1 B0 S1.00 ; disable bang-bang mode for the nozzle heater and set PWM limit
                                    M308 S2 P"spi.cs3" Y"rtd-max31865" ; configure sensor 2 as thermocouple via CS pin spi.cs3
                                    M950 H2 C"e1heat" T2 ; create nozzle heater output on e1heat and map it to sensor 2

                                    M307 H2 B0 S1.00 ; disable bang-bang mode for the nozzle heater and set PWM limit

                                    but if you get output without this, this strongly indicated that you do not have pt100 sensors.

                                        Probe P9 does not require that

                                        As you have much more experience you should take over now...😊

                                                as @Veti mentioned you can remove the M98
                                                I have removed them too, as they furthermore where not correctly coded.

                                                    your home scripts are for switches and not for probes.
                                                    there is no reason why the bltouch should deploy.

                                                    please go to the configurator and select bltouch and generate new home scripts.

                                                      Please post your deployprobe and retractprobe files.

                                                      Does the pin respond when you send M401 and M402?
