The servo motor may not be properly detected 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 communication cable is firmly plugged into the mainboard port. Check if the communication cable is broken, bent or worn.
Check port status: Check if the motor communication port on the servo mainboard is loose or damaged. Ensure the port is free of foreign objects, dust or oxidation, and clean and reconnect.
Test servo motor: Connect the servo motor to another normally functioning port to confirm if it's a motor issue.
Replace damaged parts: If you confirm that the motor, communication cable or mainboard is faulty, please contact cs@creality.com to replace the relevant parts.
For frequent errors, please recalibrate the motor: Calibrate K2 Plus Servo Motor
Check the error pop-up: Confirm which specific motor (X, Y, Z, E) is reporting an error.
Check hardware connections: Inspect the connection status of the servo motor communication cable and mainboard port corresponding to the error.
Restart the device: After completing the inspection, restart the device to verify if the issue has been resolved.
If it's a Z-axis error, please press the hot bed down to the bottom with both hands, then re-homing to see if it resolves the issue.
