Describe your issue:

…Having issues installing and using CANbus with my setup. Ran into a multitude of issues, which I’ve managed to fix. Using Katapult and Klipper and now am running into the issue of MCU ‘mcu’ shutdown: Not a valid ADC pin when I try to connect to my printer through mainsail.

You seem to use wrong pins in your setup

  • Validate against the default cfgs here: GitHub - bigtreetech/Manta-M8P
  • Note that there are different revisions of this board
  • You are using a pull-down on your probe pin, which is quite unusual. Double check.
