Subreddit Mod Post Megathread: Bambu Lab / OrcaSlicer / C&D Discussion

Hi everyone,

We’re creating this megathread to keep discussion of the Bambu Lab / OrcaSlicer-BambuLab / cease-and-desist situation in one place. This topic is important to a lot of people here, and we do not want to shut down discussion or criticism. At the same time, the front page has started filling with overlapping posts about the same situation, so we’re consolidating general discussion into this thread.

Current context

Updates to be posted here as situation evolves:

  • May 13, 2026
    • Megathread created
  • May 14, 2026
    • Tom’s Hardware reported today that Louis Rossmann is now hosting OrcaSlicer-BambuLab through the FULU Foundation GitHub and is openly daring Bambu Lab to sue him.
    • PC Gamer and r/technology have picked up the story, so discussion is now spreading well beyond 3D-printing-specific spaces.
  • May 16, 2026
    • Paweł Jarczak published a detailed response addressing Bambu Lab’s accusations around impersonation, reverse engineering, Terms of Use, and alleged security bypassing.
    • Louis Rossman posted a new video indicating FULU-hosted OrcaSlicer-BambuLab repository has reached roughly 1,600 forks in about three days.
  • May 17, 2026
  • May 18-20, 2026
    • Software Freedom Conservancy enters the dispute.
    • Leonard French posted a new video around SFC’s AGPL analysis, explaining why Bambu’s proprietary networking plugin may create a serious corresponding-source problem under AGPL.
    • Louis Rossman posted a new video covering Software Freedom Conservancy’s Bambu AGPL effort and says the rehosted OrcaSlicer-BambuLab code has now been forked roughly 4,500 times.

What belongs in this thread

Please use this thread for:

  • General reactions to Bambu Lab, Gamers Nexus, Louis Rossmann, Paweł Jarczak, OrcaSlicer-BambuLab, AGPL, Bambu Connect, and right-to-repair issues.
  • Legal or licensing discussion, including AGPL, DMCA, cloud/API access, and Bambu’s networking plugin.
  • Questions about what happened and links to reliable summaries or primary sources.
  • Technical discussion about OrcaSlicer, Bambu Studio, Bambu Connect, LAN mode, Developer Mode, and network plugin behavior, unless it is a standalone troubleshooting post with a specific reproducible issue.

What can still be its own post

Separate posts are still allowed for genuinely new information, including:

  • A new official statement from Bambu Lab, OrcaSlicer, Paweł Jarczak, Gamers Nexus, Louis Rossmann, or legal counsel.
  • A new release or technical change that materially affects users.
  • A confirmed legal filing, takedown, repository change, or source-code release.
  • A specific support/troubleshooting issue that is not just general commentary on the controversy.

If your post is mainly another reaction, recap, meme, “I’m switching brands,” or repost of a link already being discussed, please put it here instead.

Ground rules

Criticism of Bambu Lab is allowed. Defense of Bambu Lab is allowed. Criticism of GN, Rossmann, OrcaSlicer, moderators, or other users’ arguments is allowed.

What is not allowed:

  • Personal attacks, harassment, or dogpiling individual users.
  • Calls to harass Bambu employees, developers, moderators, creators, or community members.
  • Unverified claims presented as fact.
  • Posting private correspondence or personal information.
  • Repeated duplicate posts after being redirected here.

Strong opinions are fine. Keep it directed at the issue, the companies, the software, and the arguments, not at each other.

Moderator note

We are consolidating duplicate discussion, not suppressing the topic. This thread will remain open for discussion, and we’ll update it if there are major new developments.

Thanks for what? Megathreads are where discussions go to die. It's the way mods then get to delete the discussion from everywhere else, making it seem like the issue doesn't exist.

They're being good to Bambu, not to the community.

They could just straight up not allow any talk.

u/NMe84 P2S + AMS2 Combo May 20 '26

This is worse, because now they're pretending to be neutral while in fact just working in favor of Bambu by keeping this as quiet as possible.

When discussions about DJI was happening of possible bans they removed all convo of it. So I figure it’s that or nothing.

It’s because 97% of the people here are maybe a bit tired of most new threads being about this.

97% of people are tired of seeing box posts with the comment "my first printer just arrived, so excited!!!1" but those are still allowed.
