System error, try restarting.
This error indicates that the microcontroller (MCU) has been turned off and Klipper is unable to update the MCU configuration. When the MCU is off, it cannot receive any new configurations or commands, so the printer does not work properly.
The MCU stops responding: This is usually due to some previous error or issue that caused the MCU to be shut down.
Configuration errors: If some parameters in the configuration file are incorrect, the MCU may not start or work.
Hardware connection problems: For example, a connection problem between the MCU and the host (such as loose wiring or power problems) may cause this error; For example, the printer motherboard is suddenly disconnected from the hotend motherboard or other motherboards
