This sentence in Bambu Lab's blog post is wild: > We have documented incidents of service outages caused precisely by spikes in unauthorized traffic - overwhelming the servers, causing service disruptions affecting everyone. The cost was instability felt by all users. So it's a problem that their printers are popular, and they can't be bothered to scale their infra, so let's gate everything based on USER AGENT STRING! This is so crazy of an excuse that I don't believe it.

I guess if it's a security issue, it's a security issue: https://github.com/bambulab/BambuStudio/issues/10681 https://github.com/bambulab/BambuStudio/issues/10681

So am I understanding correctly that all of this "unauthorized traffic" was their customers...using their product?

  So it would seem.

Do the well-behaving clients really need to use those servers? Could you have done something to avoid this bottleneck for all users? Yeah, this is a farce.

So technically they just said that their printers would be less popular if Orcaslicer ceased to exist.

A conspiracy-theory steelmanning interpretation of that statement is that Bambu thinks that some unscrupulous Chinese manufacturer is performing DDoS attacks against them, but can't fully and publicly admit to that for legal reasons.

  ... and sending a cease and desist to OrcaSlicer somehow mitigates that DDoS?

Seems like making the slicer only able to talk to the printer via the cloud was a bad way to do things, where any issue results in “instability felt by all users.”

  They also seem to not know their nerdy customers, which means, fun times ahead :)

  It can talk to the printer directly if you use "LAN mode". This also work with 3rd party slicers like OrcaSlicer.

    This is false. After the authorization-related firmware changes last year LAN mode doesn't allow 3rd party slicers to connect. LAN mode is also abandonware with numerous issues and missing features that they've had no interest in fixing. Orca slicer has had to rely on hacky workarounds in Bambu's buggy networking plugin just to be able to connect to printers in a different subnet. https://github.com/bambulab/BambuStudio/issues/4512 https://github.com/bambulab/BambuStudio/issues/4512

You either haven't updated the firmware or you also enabled "Developer mode" which has its own issues. > This is a separate issue, I think even Bambu Studio can't connect to printers in LAN mode on a different subnet. It's not a separate issue, it's a long-standing bug in their proprietary networking plugin that they refuse to fix. Orca slicer has implemented a hacky workaround so it actually works there.

"We forced every user of every printer, worldwide, to interact with their printer through our centralized servers. This caused service disruptions affecting everyone. The cost was instability felt by all users." There, I fixed it for you Bambu. You may use it under Creative Commons.

Why don't they implement per user quota instead? Or make it so third party applications don't need to interact with their servers?
