Automatic Update: The printer should detect the files automatically. You will likely hear a series of beeps and see a progress bar or "Updating" message on the screen. Note: Do not turn off the power during this process.
Verify: Once the UI loads, go to Utilities > System > Info (or similar menu path) to verify that the version number matches the one you intended to install. Troubleshooting Tips
Update not starting? If the printer boots normally to the home screen without updating, try a different, smaller USB drive (8GB or 16GB is ideal).
Configuration Files: Sometimes firmware updates require a separate .txt configuration file to be "printed" like a G-code file. If provided, select that file on the UI and hit Print to apply specific machine settings.
