Calibrate Your 3D Printer After Firmware Update

Setup Process

After the firmware update is done, the device will automatically restart. Once the device has restarted, its screen will guide you through the setup process. Best not to skip this process but follow the instructions step by step. This may include steps like connecting to a network, self-testing, auto-leveling, vibration compensation, and more. Finally, print a test model to check the print quality.

Setup Process

If there is no notification for the setup process, you can activate it on the screen: 'Settings' >> 'More Settings' >> 'Guide'.


If the first layer of the test model has a bad adhesion to the bed, you need to calibrate your printer's Z-offset. From the screen interface, touch 'Tools' icon >> 'Control' icon >> 'Module Calibration' >> 'Position Calibration'.

The print head will automatically perform the probe and stop near the calibration module. Use the interface to move the nozzle to the center of the calibration module by controlling X/Y-axis movement. Once done, tap 'Save'. Finally, run the auto-leveling process again.
