Thermistor's shows 2000°C ( Slolved )

Please verify what firmware version you have installed using M115 in the gcode console.
Also send
M98 Pconfig.gand report back with any errors. -
Phaedrux is far more competent but I try to be helpful.
The bed Heater section seems fine,
In most cases I have seen here in this forum (if the thermistor is good), the principal culprit is bad wiring. Me too I experienced this and was bad wiring. If you just detach the nozzle thermistor you can see 2000 there also. If you plug it back , it turn normal.
I would try a cross test. You need a different thermistor for the bed to try.
Maybe you could use the nozzle thermistor on the bed channel for see if wiring are ok (of course without heat anything!). Numbers will be wrong but at least you know if there is a stable connection. -

@thomasthetrain That'll be it then. You are using version 2 firmware but your configuration file is for version 3 firmware. You need to change one or the other. If you are new to Duet, then the easiest path might be to use the online configuration tool to generate new configuration files but select the correct tool.

@giostark I have tryed to conect 100K resistors directly to the thermistor conector
on on my duet and it behaves exactly the same -
@thomasthetrain See my post above. When you use the configuration tool, under "Firmware version" there is a drop down list. Select "2.03 to 2.05" in that list.

Ok Thomas.
Deck is right , you are using the v2 firmware with v3 settings.
For upgrade the firmware from 2 to 3 you have to make before 2.xx.x>3.0 then 3.0>3.1.1
If you have the panel due don't forghet to add this line on top :
M575 P1 S1 B57600; enable panel due to connect properly
