Can not update mcu 'mcu' config as it is shutdown (flsun sr)

Hello @IsacityXD !

Some BG info:


Sounds like EMI issues:

  • Are there high power devices near by: washing machines, ACs, fridges …
  • Do you have a short and high quality USB cable between Klipper host and printer?
  • Are Klipper host and printer on different outlets or, what is way better, on the same one?
