Bambu Lab Firmware Open Beta Program

Our software development team is working hard in delivering new features and improvements to our printers by providing regular firmware updates. 

While we also have an internal team that provides QA to ensure as many bugs are squashed before final release, it is hard to test any potential scenario with the various different ways our customers use our products. 

Because of that, we are opening our Firmware Beta to everyone who wants to test it and help us make it better. 

What is the Bambu Lab Firmware Open Beta? 

The Bambu Lab Firmware Open Beta is a program where we offer the possibility to test and use latest firmware features before they become publicly available in the Release version. Usually, the Beta Firmware is released with up to 1 month in advance, before the final release is available. During this period, multiple firmware updates are made available to the participants, where different features can be used. 

In some situations, new features that are implemented in the Open Beta might not be present in the Official Release, if the development team considers these functions not to be ready for public use. 

Important Considerations

Before joining the Bambu Lab Open Beta program, make sure you have read all the terms and conditions present here: Bambu Lab Beta Firmware Program Terms
Joining the Open Beta program will confirm that you explicitly agree with the information presented in it. 

  • Ensure your printer is working as expected before installing Beta firmware. You can do this by performing a full calibration procedure, then doing a small print to confirm everything works within expectations after ensuring the plate is washed with hot water and detergent. Of course, if you know your printer is already working as expected, you can skip this step.
  • If you find specific problems related to the hardware (hotend errors, problems with heating, fans not turning, etc) please revert to the previous firmware first to confirm if the issue only occurs on the Beta firmware, or it can also be reproduced on the Public Release version
  • Avoid posting questions about potential issues you might have in public forums or social media. This is to avoid inaccurate information from being spread, or to cause unnecessary concerns for users that don’t have the Beta firmware installed. 
    If you wish, you can discuss about beta program, report issues and even interact with our developers in our dedicated Beta section on the forum.

We recommend avoiding the installation of Beta Firmware if you are not planning to use the machine to test new features.
Unreleased firmware can contain bugs that lead to print failures or different behaviors of the printer which have not been considered.
