### Describe your issue:
HI all, so getting the following error after i have setup canbus with EBB36 and U2C
MCU ‘EBBCan’ shutdown: ADC out of range
This generally occurs when a heater temperature exceeds
its configured min\_temp or max\_temp.
I am using the basic settings and the temp probe is a stock one from and Creality spider v2 hotend.
Thanks for any and all help

Any reason a thermistor is not plugged into TH0?

Seems he put it into the PT1000 connector or is using this sensor.
