This prompt indicates that the device has detected that the independent power supply of the CFS2 drying module has been cut off or is experiencing a power supply anomaly. The filament drying and automatic dehumidification functions require an independent power supply to power the heating components, fans, and related control circuits. When the system detects that the independent power supply is disconnected, it will stop the filament drying/automatic dehumidification function.
- Check the external power supply: Confirm that the power outlet is supplying power normally, the plug is firmly inserted, and the outlet switch or power strip switch has not been turned off.
- Check the power supply environment: Avoid sharing an unstable power strip with high-power devices, and avoid voltage fluctuations, poor outlet contact, or power overload.
- Replace the power cable and check whether the power supply is normal and whether drying functions properly.
- Check whether the wall outlet, power strip, or power socket is supplying power normally, and confirm that the outlet switch has not been turned off.
- Check whether the CFS2 independent power cable is firmly plugged in, and confirm that the power cable is free of damage, crushing, excessive bending, or poor contact.
- If the independent power supply still cannot supply power normally, or the device repeatedly prompts a power cut-off, the drying independent power supply module, power board, or related wire harness will need to be replaced.
- After troubleshooting, restart the device, enter the filament drying/automatic dehumidification function, and confirm that the heating, fan, and temperature/humidity control have returned to normal.
