R25 should sit between R5 and D20, except here it's on the pullup, which is wrong. Likely a hardware design bug not caught in the beta test. Mentioned it to @cneshi.
I have patched this in Kalico So you can now use inline_resistor to correct the wrong temperature readout. But ideally this needs a minor board revision at some point. Would recommend updating the docs to highlight the issue.
[temperature_sensor chamber]
sensor_type: PT1000
sensor_pin: sb:PB2
pullup_resistor: 4700
min_temp: 0
max_temp: 100
inline_resistor: 165
The inline_resistor parameter works in both Klipper and Kalico for NTC thermistors. Fix in software looks like:
