Closed printer not extruding

You have some

MCU 'SHTCan' shutdown: ADC out of range

errors in your log.

Please be more specific:

  1. Does the extruder simply stop extruding? OR
  2. Are you getting an error message?

From your log, my guess would be #2 and this could mean

  • Faulty thermistor on the hot end (wiring or thermistor itself)
  • The board does not like the increased temperature caused by the enclosure.

I usually print ASA, PC and similar filaments, so always with a housing. This is exactly the reason why I do not use CAN boards, as I cannot keep them away from the increased temperature and the components on the CAN board like it cool rather than hot (apart from the fact that it increases the complexity quite a bit → more things to fail).
