Bambu Lab Authorization Control System: Difference between revisions

A significant concern raised by the community revolves around the wording in Bambu Lab's [[Terms of Service]] and firmware update announcements. Critics and users argue that the phrasing leaves open the possibility for the manufacturer to remotely disable printers that are not updated to the latest firmware. Specifically, Bambu Lab's Terms of Service<ref name=":2">{{Cite web |date=24 Apr 2024 |title=Terms of Use |url=https://bambulab.com/en-us/policies/terms |url-status=live |archive-url=https://archive.is/KZqib |archive-date=27 Jan 2025 |access-date=1 May 2025 |website=[[Bambu Lab]]}}</ref> states that printers '''"may block new print jobs"''' if updates are not applied, which some users interpret as a potential pathway for forced obsolescence.<ref name="firmware-update-introducing-new-authorization-control-system-2">https://blog.bambulab.com/firmware-update-introducing-new-authorization-control-system-2/ ([https://web.archive.org/web/20260223032912/https://blog.bambulab.com/firmware-update-introducing-new-authorization-control-system-2/ Archived])</ref> While defenders of Bambu Lab point out that offline modes such as SD-card printing and LAN-only setups would remain functional, others point out that the Terms of Service do not explicitly limit this restriction to cloud-based printing. This ambiguity has led to speculation that Bambu Lab could enforce broader limitations, effectively rendering printers inoperable for users who choose not to update.<ref name=":3">{{Cite web |last=@nickjohnson |title=Bambu Lab reserves the right to brick your printer until you update the firmware |url=https://old.reddit.com/r/BambuLab/comments/1i45iy2/bambu_lab_reserves_the_right_to_brick_your/ |url-status=live |access-date=1 May 2025 |website=Old Reddit |archive-url=http://web.archive.org/web/20250119220606/https://old.reddit.com/r/BambuLab/comments/1i45iy2/bambu_lab_reserves_the_right_to_brick_your/ |archive-date=19 Jan 2025}}</ref>

Newly received X1E printers with firmware 01.01.02.00 will not connect to the Bambu Studio using the Lan only method password. Bambu Studio identifies the un-logged printer but will not allow a connection to the printer. Only after connection / account paring is done over the Bambu Handy app by giving internet access to the PC and Printer then utilizing the cloud service connection will Lan only communication and login work.<ref>{{Cite web |last= |date=Sep 2024 |title=Connect X1E to stand-alone computer |url=https://forum.bambulab.com/t/connect-x1e-to-stand-alone-computer/101474 |url-status=live |access-date=1 May 2025 |website=Bambu Lab Community Forum |archive-url=https://web.archive.org/web/20260223033045/https://forum.bambulab.com/t/connect-x1e-to-stand-alone-computer/101474 |archive-date=23 Feb 2026}}</ref>  

*Access camera feeds through third-party applications<ref name="bambulab-forum-135400/9">{{Cite web |last=@hho |date=16 Jan 2025 |title=Am I wrong in understanding that Bambu Connect is just a upgraded version of what used to be the network plugin? The difference is that it’s not a plugin anymore. The only API offered is signing/sending .3mf files – everything else is only in Bambu Connect, but not available to other tools anymore: No syncing AMS filaments, no access to cloud-synced print profiles, no manually moving/heating the printer, no monitoring progress, no access to the camera etc. So yeah, Orca could probably implement a new “Send” button, but the “Device” Tab will be gone and preparing prints would also be a lot worse… I still don’t fully understand why they’re doing this. If they did it to Bambu Studio as well, then it would make more sense (not linking their closed-source plugin against the GPLd slicer anymore, finally complying with the license), but as it stands it seems they’ll only kneecap Orca (and any goodwill in the community around it). |url=https://forum.bambulab.com/t/this-new-auth-system-will-make-me-sell-my-printers/135400/9 |url-status=live |access-date=1 May 2025 |website=Bambu Lab Community Forum |archive-url=https://web.archive.org/web/20260223033106/https://forum.bambulab.com/t/this-new-auth-system-will-make-me-sell-my-printers/135400/9 |archive-date=23 Feb 2026}}</ref>

The manufacturer states this change is required for security, but community members note that many of the security vulnerabilities being addressed stem from Bambu's own cloud-centric design choices rather than inherent risks of local network control<ref name="bambulab-forum-134549/12">{{Cite web |date=14 Jan 2025 |title=Bambu Studio 1.10.2 Public Beta |url=https://forum.bambulab.com/t/bambu-studio-1-10-2-public-beta/134549/12 |url-status=live |access-date=1 May 2025 |website=Bambu Lab Community Forum |archive-url=https://web.archive.org/web/20260223033127/https://forum.bambulab.com/t/bambu-studio-1-10-2-public-beta/134549/12 |archive-date=23 Feb 2026}}</ref>.

At the time of writing user Tzeny15 on reddit, has authored a five step guide to blocking internet access for the Bambu P1S as a precaution in case the manufacturer attempts to limit functionality for printers without the newest firmware.<ref> {{Cite web |last=@Tzeny15 |title=LAN mode with live view, remote monitoring+control and blocked internet access - a five step guide |url=https://www.reddit.com/r/BambuLab/comments/1i4vp5i/lan_mode_with_live_view_remote_monitoringcontrol/ |url-status=live |access-date=1 May 2025 |website=[[Reddit]] |archive-url=http://web.archive.org/web/20250310115818/https://old.reddit.com/r/BambuLab/comments/1i4vp5i/lan_mode_with_live_view_remote_monitoringcontrol/ |archive-date=10 Mar 2025}}</ref>

While the project was not made in response to Bambu's announcement, there has been a wave of new public interest in this specific project. ChazLayyd's documentation instructs P1S owners to non-destructively remove the old control electronics that run Bambu's proprietary software and instructs P1S owners to install off-the-shelf control components so that the existing motor connectors and other critical electronics can communicate with the newly-installed off-the-shelf control components.

Customer reactions have been overwhelmingly negative.<ref>{{Cite web |last=@hho |date=15 Jan 2025 |title=Improvements Introduce authorization and authentication protection mechanism: Bambu Studio now supports signing and encrypting control commands sent to printers when the printer supports authorization and authentication protection. The printer will determine whether the commands can be executed. Hmmm. This reads suspiciously vague. It could mean that Bambu printers get an onboard permission handling, so that you can “lock down” your printer and set what commands can be run. But it could also mean that Bambu printers in (or of?) the future will only run Gcode encrypted and signed by Bambu Studio… |url=https://forum.bambulab.com/t/bambu-studio-1-10-2-public-beta/134549/4 |url-status=live |access-date=1 May 2025 |website=Bambu Lab Community Forum |archive-url=https://web.archive.org/web/20260223033306/https://forum.bambulab.com/t/bambu-studio-1-10-2-public-beta/134549/4 |archive-date=23 Feb 2026}}</ref><ref>{{Cite web |last=@iranintoavan |title=Firmware Update Introducing New Authorization Control System |url=https://old.reddit.com/r/BambuLab/comments/1i2psvz/firmware_update_introducing_new_authorization/ |url-status=live |access-date=1 May 2025 |website=Old Reddit |archive-url=http://web.archive.org/web/20250403012526/https://old.reddit.com/r/BambuLab/comments/1i2psvz/firmware_update_introducing_new_authorization/ |archive-date=3 Apr 2025}}</ref> Bambu Lab has historically pushed cloud-based printer interaction while offering limited LAN mode functionality<ref name=":4" />.
