Basic Information:

Printer Model: SP5
MCU / Printerboard: SKR2
klippy.log

Describe your issue:

Printer was being setup for a new camera and on a restart it just failed to load with the ADC error. the logs show my temps are in range unless Im reading it wrong.

mcu_temp: temp=-2.6

vs.

[temperature_sensor mcu_temp]
sensor_type = temperature_mcu
min_temp = 10
max_temp = 100

Although I have no clue, why it should read -2.6°C.
Maybe set min_temp = -10 and watch it. Could be some initialization glitch.

Thank you. Not sure why it’s reporting so low.
