¶ When to calibrate
When the servo motor operates abnormally, makes unusual noises, or easily triggers protection faults, it may be due to a change in the servo motor's zero position. In this case, the servo motor's zero position needs to be recalibrated.
Below is a one-click calibration Gcode that can read the servo motor's original zero position information and recalibrate it.
¶ Calibration tool
Servo motor calibration is completed by executing Gcode.
To confirm success, use the Fluidd interface:
Open a browser on your computer and obtain the printer's IP address from the machine's network interface
Enter the machine's IP address plus port number ::4408 in the browser (e.g., 192.168.1.1:4408) to access the Fluidd window.
¶ Calibration steps
With the motor in a disabled state (you can click motor unlock on the screen), move the nozzle to the center and push the hot bed to the bottom:

Log in to the Fluidd backend. Enter the machine's IP address plus port number ::4408 in the browser (e.g., 192.168.1.1:4408) to access the Fluidd window. Upload the Gcode file to the machine, run the motor calibration Gcode, and wait for the calibration to complete.
¶ Calibration Gcode File
| Supported Version | Description | Gcode |
| 1.1.1.3 and above | Motor Calibration Gcode | 1.1.1.3 and above version Gcode File |
| 1.1.1.3 below（exclude 1.1.1.3） | Motor Calibration Gcode | 1.1.1.3 below version Gcode File |
When the terminal prints "Done printing file", it indicates that the calibration is complete. At this time, you need to take a screenshot of the calibration feedback information and send it to customer service (cs@creality.com). (Note: The machine must not be powered off during the calibration process, otherwise abnormalities may occur!!!)
Calibration is now complete, and you can proceed with other operations.
