As part of our ongoing commitment to enhance the overall security of our products, we are introducing an authorization and authentication protection mechanism for the connection and control of Bambu Lab 3D printers. This step is a significant security enhancement to ensure only authorized access and operations are permitted.

This change is mitigating any risk of remote hacks or printer exposure issues that have happened in the past and also lower the risk of abnormal traffic or attacks. 

Introduction of Firmware and Software Updates

Starting January 16th, users will have access to the beta firmware, with the official release following on January 23rd:

• New firmware update for X1 Series 3D printer (version 01.08.03.00 or above).
• Corresponding new versions of Bambu Studio (version 01.10.02.64 or above) and Bambu Handy (version 2.17.0 or above).

These updates will introduce authorization controls that require official authorization for critical printer operations. Furthermore, unauthorized third-party software will be prohibited from executing critical operations.

During this transition, we’re working closely with our integration partners to ensure a smooth migration to the new security framework. Our team will provide comprehensive documentation and support to assist with any necessary adjustments.

Critical Operations That Require Authorization

The following printer operations will require authorization controls:

• Binding and unbinding the printer.
• Initiating remote video access.
• Performing firmware upgrades.
• Initiating a print job (via LAN or cloud mode).
• Controlling motion system, temperature, fans, AMS settings, calibrations, etc.

Operations That Do Not Require Authorization

The following actions will remain unaffected by the authorization mechanism:

• Sending status information from the printer (e.g., MQTT status push for tool
