The reason for this prompt is that the processing power of the microcontroller (MCU) exceeds its predetermined load range, which usually occurs during the process of input shaping. The frequency of the stepper motor is too high, causing the timer to fail to execute the operation on time, and then an error occurs. This is mainly due to the need for a lot of computing resources in the process of input shaping, resulting in the microcontroller (MCU) can not respond in time.
Restart the device: Try restarting the device to see if the problem is alleviated.
Select input shaping only: Select input shaping only and do not check Auto leveling to reduce the burden on the microcontroller when the device self-tests.
Update firmware or restore factory Settings: Make sure the device is running the latest firmware version, or restore factory Settings to resolve possible system issues.
Restart the device.
In the self-test process, select only input shaping, and do not select other options such as auto c leveling.
Update the device firmware to the latest version or restore the factory Settings.
