⚠️ Please make sure to follow the "Guide" and do not skip any steps.

After updating the firmware, in the main interface, click on the "Tools" icon, "Control" icon, "Module Calibration", "Position Calibration". The machine will automatically perform detection and pause near the top of the calibration module. You could adjust the nozzle to the center position of the calibration module using the distance units and X/Y axis movement direction on the interface. Once done, click "Save," and finally, perform the automatic leveling again.

Click on the top-left corner "<" icon to return to the Settings interface. Click "More Settings", "About Machine", and the red arrow icon (➡️). The device will prompt you to confirm the upgrade. After confirming, the firmware upgrade will automatically complete within 3 minutes.

It will automatically restart after updating.'

3. Device Calibration

After the firmware upgrade is complete, the device will automatically restart. Once the device restarts, it will prompt you to go through the setup process again. Please do not skip this setup. Follow the on-screen instructions carefully.

If you do not receive a prompt, follow these steps: On the main screen, click on "Settings." Click on "More Settings." In the next screen, click on "Guide." It will be asked if you want to enter the user guide; click "Confirm" (✔️) to proceed. This will ensure that the device is properly calibrated after the firmware upgrade.

4. Version Confirmation

Go to "Settings" (⚙️), "More Settings", "About Machine", and check if the firmware version has been successfully updated.

3. Troubleshooting

If there is a leveling anomaly, please follow the steps below to check:

After powering off, check the wiring of the leveling calibration module to ensure it is connected properly. Then, restart the machine.
Press 'Tools' (?️) > 'Control' (?️) > '[Module Calibration]' > '[Position Calibration]'. Use the [X Move] and [Y Move] options on the screen to move the nozzle to the center point of the calibration module. Once done, click [Save]. Afterward, perform the leveling operation again.
