There is a new Bambu Studio update:

Is this the new “auth system”

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.
Don’t know but seems pretty clear…
Won’t make much of a difference though as long you can still run the old firmware on the printer.
But I guess you wanted to state it is the problem now rather than posting it as a question without a question mark ?
Just realised something that I mentioned when all this hype started already caught up with us…
Some people are reluctant when it comes to these new ‘security’ features.
May that be rightful or not, problem now is that we have to make a choice - or no more choices, depending on how you see it.
If you don’t agree with those security changes you can (so far at least) stick with a firmware still free from it.
As long as there is the option to downgrade one can try and go back.
Problems start if you decide the added security stuff isn’t your thing but you still do want the updates and bug fixes…
Sticking to an older version of Studio still works, same for the firmwares.
The time WILL come where the list of bug fixes and minor improvements is long enough to justify a major update of Studio.
And the time Will come where there will be a new firmware that fixes things we still struggle with or that Studio requires you to have a minimum firmware version installed and vice versa.
So far every major company with products requiring a bundled software and firmware forced users to either ‘update or to keep suffering’.
We should be grateful that a Chinese company like Bambu still does not enforce updates like so many western ones do for years.
Give it a while and we will see how all this ends for both sides.
If Bambu really sticks to their pledge of not forcing users to go this route then the time is right for them to explain how we can still have bugfixes and such but go without all this security stuff.
Since all data going through THEIR cloud is encrypted we don’t have any way of knowing what is really transmitted home.
But without the cloud users are intentionally crippled in LAN only mode.
No offence Bambu but I see more questions now than answers…
This version “Bambu_Studio_win-v01.10.02.76.exe” is running, very, very, very slow on my PC. It takes much longer to open .3mf files. Takes longer to switch from “Prepare” to “Device” view in the program. It was running so slow that I re-installed an older version “Bambu_Studio_win_public-v01.10.01.50-20241115162711.exe”.
After reinstalling the older version, the speed issues disappeared.

I am having trouble with the latest Linux Flatpak version (1.10.2.75) from the stable hub in that it can no longer see my A1 mini. If I revert back to 1.10.1.50 (previous version), it works correctly.
Are anyone else seeing this problem. I have switched of updates for the moment for Bambu Studio and will continue with 1.10.1.50.

I and many others aren’t grateful to Bambu cause this "freedom of choice " came out as a result of the community’s backlash… here, on reddit, on Facelift, including on multiple YouTube channels… so, sorry buddy, but Bambu just took a step back from pushing the new "security firmware patch " on all their existing machines (starting with X1 series) and the new ones, due to community’s public outrage, and actually had to accept that owners of the existing machines don’t have to “update” to the new firmware if they chose not to.
Personally, I don’t see any logical, technical or reasonable reason for having to print through their (poorly secured) cloud, when everything goes smoothly and much more secure through my LAN.

i cannot see my printers since the last update (linux/mint/flatpak)
i logged out and now cannot login again with my google account
(get_user_profile_error_-1)
Same problem here, I cannot see my A1 anymore. I reverted back to 1.10.1 as well.
Look carefully and put the lights on. It’s pretty obvious you can’t see it in dark. You need the lights on.

Ok, don’t why but I did not update to the auth version yet…
And while the ‘security’ part of it is involved my decision is more based on the hassles after previous updates.
You have a little problem, like with the network plugin and the first Wiki finds are things like this 
I am always VERY impressed if the ‘fix’ for a problem a company causes with their demands results in suggesting I should just forget about MY security, MY needs…
Or just trying to keep printing after an update to find out the old 3MF won’t print as they used to…
Not to mention all those issues with messed up profiles failing to load while Studio does not even have a proper installer to take care of those things.
It is this Chinese mentality of barely functioning still being good enough that drives me up the walls.
The last straw(s) for me in this game was finding out that it SEEMS even in Lan only mode my printer tries to contact some weird Chinese IP almost every time I turn the printer on paired with the popup telling me there is another Studio version I shall download and install.
Needless to say Bambu now plays the bigger thumb game by forcing users to decide between getting often vital bug fixes or to stay stuck with old firmwares and Studio versions.
Been there done that a few times and you know what always worked well for me so far?
Wait it out for a while and if the ompany keeps treating users like horse manure while only providing lies as answers for their measure you get rid of the device(s) and go with some company that still values their customers and users.
Problem these days is that such a decision impresses a company about as much as the window cleaner running out of water…
Until some EU authorities step in not much will happen and even then, as we know from FB, Google and other court rulings - it won’t affect other market regions…
Why not simply do what works so well for other devices and combo’s?
Get some ‘modded’ Studio version for a custom, user based fork that is kept updated, grab a minimalistic and well working network plugin while at it and if that’s still not enough just download one of the many ‘custom roms’ and be happy…
If you have a device from the pioneer in this game, Apple, you already know that a ‘jailbreak’ is about as far you get and that after that not all is as golden as advertised.
For other devices you can a bit more luck, especially in a certain Polish forum but it always leaves the same bitter taste behind > Why do I have to do all this just to get a device working the way it should…
It is the SHOULD that drives company and users crazy LOL
Opinions differ and so far not a single phone manufacturer decided to provide a truly open source firmware…
Why? Well, go ahead and check what corresponds to Bambu’s network plugin does…
No chance to find out what those Sim cards really do and even less chance to find out that it is all done to allow tracking…
How far could Bambu drive this game ?
As far as they want, really…
Bambu knows we won’t and can’t just sell our printers in frustration to move to a competitor…
Yes, we can…I even know a few who have sold their machines already, and several others who are in the process of selling. Some had but a few and was easy to sell, while others have print farms, and that means replacing each sold Bambu with other brands…and that takes a bit of time to complete…
I’m not going to sell my machines, not until i run out of the stockpile of spares I’ve acquired for them, or these can’t be fixed anymore…
Staying with the last known 3rd party friendly firmware and not updating Studio and Handy won’t really pose any problems to me (considering that I rely on Orca, and Handy is more of an afterthought) …as long as it keeps printing as before.

Now solved by updating Flatpak version to 1.10.2.76.
I see that they added Sunlu filaments.
Has anyone else noticed that Sunlu PETG doesn’t show as a filament choice even when it is checked in settings…??
Yes, “so it begins again” I was glad to see it all the jibber-jabber gripping about the last update stop a few weeks ago. I hoe this thread will stick to the topic of issues with the firrmware up date only. I personally with hold off updating until I hear more about how the update goes.
We haven’t updated, but since yesterday, we can’t send prints anymore, and a number of random printers on our farm aren’t reachable in the Studio. This seems awfully suspicious to us.
It is shown, if I select my P1S as printer, but not with my A1 mini. Maybe there are some issues in the filament definition.

If you haven’t updated yet your firmware, have you tried sending via Orca?
For those who updated and dont have your custom profiles anymore, I beleave this is happening because we are not uploading to the cloud or were working offline when we created the profile. Here is a solution.
In Bambu labs do the following,
1- go to the down arrow at the top pf the screen
2- go to help then show configuration folder
3- open User folder, then Defaults folder (Here you will find folders named Filament, Machine, and Process these folders contain your presets)
4- Copy the path to the Defaults folder
Next go back to Bambu labs
1- Click Files at the top of the screen
2- go to Import then Import configs
3- at the top where it shows what folder your in, click here and paste the path we just copied, this should take you to the default folder.
4- open a folder and check all configurations you want to import then hit open,
a popup screen will appear click ok. (You will need to do this for each folder in the defaults folder)
Your presets should now be available.
I hope this helps
