PT1000 Temperature readout minus (-)225 degrees

Hi All,

I'm building/testing my first VCore 3.1 500 with EVA toolhead, Phaetus Raido v2 UHF PT1000, Octopus 1.1 with EBB42 toolboard

After a few day's of print still tuning the machine it suddenly stopped.

MCU toolboard shutdown ADC out of range.

I tried 3 different PT1000 with no change.
Then i added min max temperature just to see what the PT1000 is measuring.

sensor_type: PT1000
pullup_resistor: 2200
min_temp: -273.15
max_temp: 300

I have the jumper on the EBB42 toolboard placed.

The temperature readout is minus 225,4 degrees Celsius!
I have no clue what causes it.

Any suggestions. Your help is much appreciated.
