Temperature reading problem. #84

Closed JakubRybakowski closed 2 years ago

Hello, I changed the motherboard from E3 DIP to SKR 2. I have a problem with reading the temperature. Both for the nozzle and bed. I have measured the nozzle.

The software is marlin 2 bugfix.

My sensor is 100k NTC. I have set to 1 in the software.

Measured (real) temperature -> temperature on the printer display.

19 -> 42 70 -> 100 105 -> 150 150 -> 200

What may I have a problem with?

Can anyone check the resistance on the disabled board at the TB TH0 TH1 output?
