New H2C Firmware Available for Public Beta Testing!
How to Join the Beta
To access the beta firmware, simply join the Beta Firmware Program via the Bambu Handy app under Me → Beta Firmware Program.
Once enrolled, the update will be pushed to your device gradually.
How to Switch Back
You can leave the Beta Program at any time by disabling the option in the app and installing the latest official firmware version.
New Features
1. Added support for the Filament Track Switch
The filament track switch is specially designed for dual-nozzle printers, equipped with 2 filament inlets and 2 filament outlets, and supports seamless mapping between AMS and dual nozzles. For more details, please refer to the wiki
This feature requires Bambu Studio v2.5.3.60 or later / Bambu Handy V3.18.0 or later.
2. Added support for remotely enabling the AMS drying function
Users can now turn on the drying feature for the AMS 2 Pro and AMS HT from both Bambu Studio and Bambu Handy. Ensure the latest update is installed for both.
3. Added support for printing while filament is drying when using AMS 2 Pro and AMS HT. (Lower drying temperature during printing)
4. Added support for TPU printing on the left nozzle, for TPU with a hardness of 90A or higher
5. Added support for starting prints over LAN without requiring a USB storage device
6. Added foreign object detection beneath the heatbed. Requires Bambu Studio version 2.5.3 or above
7. Added live image display in AI detection error pop-ups
8. Added a Regulation Certification page for certification e-labeling
9. Added Purify Air at Print End option
This option can be set in the slicer or with a button in the UI. It will purify the air for 3 minutes after the print is completed. Requires Bambu Studio version 2.5.3 or above.
10. Added a “Stopping” state after a stop command is initiated
During this state, the printer blocks user input until the stop process is complete, preventing control command sequence conflicts caused by additional inputs during the stopping procedure
11. Added a filtering option with cooling mode for the adaptive air circulation system
This option can be enabled via the slicer or the printer UI, and it’s mainly used to filter the air when exhausting the air for low-temperature filaments. Requires Bambu Studio version 2.5.3 or above.
12. Added BirdsEye camera initialization for the Cutting Module
13. Optimized the filament color display on the filament editing page, adding support for gradient and dual-color filaments
14. Added support for Rotary Attachment. Requires Bambu Suite 01.02.02.00 version or above
New support for laser machining of cylindrical and rotary workpieces by integrating a rotary attachment
Combined non-contact 3D mesh measurement with motion planning algorithms to generate and execute processing paths for both cylinders and rotary bodies. The overall workflow is streamlined, integrating multiple functions into a single click, and achieves a “What You See Is What You Get” experience through camera-based positioning.
Added a new page for real-time rotary attachment angle monitoring
This page allows you to adjust the target object to a horizontal position before engraving, ensuring the captured unwrapped image better aligns with the actual object and improving overall engraving precision.
Feature Optimizations
- Improved the accuracy of build plate offset detection.
- Optimized collision detection for the purge bin.
- Improved motor noise-related surface defects at low speeds.
This optimization requires recalibrating motor noise reduction after upgrading to take effect.
Important: If rolling back from this version to version 01.01.05.00 or earlier, motor noise reduction calibration must be performed again to ensure proper operation.
- Improved the issue where the flow blocker could potentially bend following a nozzle flow calibration.
Known Issues:
- Filament PTFE tube detachment detection is temporarily disabled.
