Hello!
Thank you for contacting the Bambu Lab Support Team.
Bambu Lab is committed to making cutting-edge technology affordable with advanced know-how and high production quality. Nonetheless, users may experience frustrating situations where a model doesn't print correctly. These failures could be caused by structural damage, the HMS reporting an error code , or dissatisfaction with the printed model's appearance.
You can obtain detailed error information for the printer by clicking on the assistant information displayed on the screen. Additionally, you can scan the QR code or search for error codes on the HMS main page to access troubleshooting guides for specific issues. When submitting a support ticket, we strongly recommend capturing the error HMS information displayed on the screen and providing it to our technical support team for prompt analysis of the problem.
Take A1 as an example
