I made it work on the extruder, I could measure that there was a loose connection on that end and the other is probably completely finished. Thank you very much for the resistance table and your help. Without that I think it would have taken me a very long time before I had found the problem.

I have tried with that code but this is the result
Hey. I have a problem with my pt100 sensors.
As shown I use 2-wire pt100 and jumper on the left and soldered them in pairs and wrapped them to the right.
As shown in the picture I get an MCU temperature that is only about 10 degrees too much but on the extruder and the bed I get the absolute zero point. And when I press the unit I get the error that can be seen in the bottom right corner of the image. I have tried and read everything I could find on Duet3D's website and have not been able to solve it, but this is also the first time I try this so it's probably me who does not understand it but I would greatly appreciate some help so I can move on.
Here is the code I use for my heaters.
; Heaters
M308 S0 P"bedtemp" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermocouple via CS pin spi.cs1
M950 H0 C"bedheat" T0 ; create bed heater output on bedheat and map it to sensor 0
M307 H0 B0 S1.00 ; disable bang-bang mode for the bed heater and set PWM limit
M140 H0 ; map heated bed to heater 0
M143 H0 S120 ; set temperature limit for heater 0 to 120C
M308 S1 P"e0temp" Y"thermistor" T100000 B4138 ; 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
M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
Thanks. I'm reasonably new to this and thought I knew the difference between CoreXY and a Cartesian printer.
Thank you very much for your help I have fixed it now so it runs as it should

And thanks for help
I have a problem with my CoreXY 3D printer – it moves in both X and Y direction even I only ask for movement in one of the directions.
When I ask for a movement of X or Y it does so in both the X and Y direction – this means that it only will move diagonally.
I am able to make it move in one axis direction using G1 H2 X / Y specified mm; but it still moves diagonally when I press “Home” on X and Y so that does not solve the problem.
I hope one of you are able to help me with a solution – so it only moves in the direction I specify.
