The servo motor may not be detected normally by the system due to loose hardware connections, unplugged connectors, or motor failure, triggering this prompt.
First, check the screen to see which axis is reporting an error in the pop-up window:
Check servo motor connection: Confirm that the servo motor cable plug is firmly inserted into the mainboard interface. Check the cable for signs of breakage, bending, or wear.
Check wiring: Look for damage or looseness at the motor interface on the servo mainboard. Ensure there are no foreign objects or oxidation in the interface, and clean and reconnect if necessary.
Test servo motor: Use other normally functioning ports to test the servo motor to confirm if it's a motor failure.
Replace problematic parts: If motor or motherboard failure is confirmed, please contact cs@creality.com to replace relevant parts.
Check error pop-up: Confirm which specific motor (X, Y, Z, or E) is reporting an error.
For E-axis errors: First click the Retry button to see if it can recover. If retry fails to recover, click Help > Error History to check if there were any filament feeding/retracting errors before the error occurred. If so, please prioritize solving the feeding/retracting problem before attempting to retry.
Troubleshoot other motor failures: Check hardware connections and motor operation one by one according to the above solution steps.
Restart the device: After completing problem investigation or handling, restart the device to verify if the fault is resolved.
