@Veti Thanks

Is it better to update to version 3 or to select version 2 in the reprap configurator?

@theruttmeister I have replaced the connectors but it doesn't work.

I did not use the duet conectors but these make good contact, i have measured them.

I'm seting up my tronxy x5s with an duet 2 ethernet, but i can't figure out how to fix the temperature readings. I keep having the error: Temperature reading fault on heater 1: unknown temperature sensor channel. This is also for heater 0. Because of this the temperature reading are 2000C. The wiring and the thermistors are all good.
What am I doing wrong?

The config.g of the heaters:
; Heaters
M308 S0 P"bedtemp" Y"thermistor" T100000 B3950 ; configure sensor 0 as thermistor on pin bedtemp
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 B3950 ; configure sensor 1 as thermistor on pin e0temp
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
