This is all nonsense. I just got a a1, and its my first 3d printer. I dont have any expertise. Ive been able to use the Bambu App and Maker world and basically control+P. Ive print about 10 things so far in the first week. I dont see why people are mad. They made the apple of printers. It just works(tm). I dont need anything else. People just get so upset over nothing.

I am angry at the bait-and-switch Bambu is pulling. I bought one of their printers in the Black Friday sale on the understanding it was reasonably hackable and open. Now they're trying to lock it down so I can't print on my own printer without using their approved software and DRM chain. It's outrageous. More info on the hacking (the first in what may be a long stupid fight): https://hackaday.com/2025/01/19/bambu-con…

They were selling at or sometimes below the price point of printers that you build yourself.

They're good products, and they are clearly selling at a low enough price point to push for market capture.

The pricing, special features tied into their own AMS + filaments, special features tied into their own slicer. These all indicate that they were building towards this sort of behaviour.

I've been on the fence about purchasing a Bambu. But given the amount of time I've spent over the past few years having to tweak my ender 3 V2 and CR-10- I was leaning towards finally splurging on a X1C.

Question to those more familiar with the bambu software ecosystem - do these recent changes to authentication require a constant online connection to print anything from a machine on the LAN? I'm assuming printing via microSD will still be possible?

If you are looking for alternatives, I highly recommend the Qidi q1 pro Despite an initial issue with the hot end (which was easy and fast enough to fix with help from support). I’ve been really happy with it It prints pretty much anything. Fast, reliable and very cheap compared to equivalent printers in the market

Voron for life

I’m not familiar with Bambu, I’m a Prusa user, but if I had to guess you would always be able to print via microSD. It would be wildly unpopular to disable local printing.

Currently the only thing which won't run on a non-google blessed android build is google wallet, although a lot of applications rely on google's proprietary services exposed through google play. I've not ran into any banking applications which won't run on a non-google build of android (as then they would only run on a pixel).

This is false. List of apps which refuse to run on my old OnePlus 6 which I revived with LineageOS: - Danish national identity app (MitID). I had to get a hardware token that generates one-time passwords. - My banking app (still works in the browser though). - The de facto payment app used for peer-to-peer payments and as a credit card alternative all over Denmark (MobilePay). - The app for controlling the heating sy…

I don't know much about LineageOS but GrapheneOS supports attestation (albeit with its own keys) and it works for all the banking apps I have had the displeasure of using here in the UK including revolut.

If LineageOS did support those APIs (which it can support if it wanted to, without any blessing from Google) then presumably most if not all of those should also work.

Try GOS and see if it's broken there. If it works on GOS then you can shout at google for ever exposing the attestation APIs but the apps you're complaining about aren't actually abusing attestation in the way you claim, LineageOS is simply choosing not to implement the features they rely on.

AFAIK, Apple has never retroactively removed functionality from devices people already purchased Selling a walled garden is one thing, building walls around a garden you already bought is another thing entirely

They did even worse. New firmware upgrades made older devices slower and painfully unusable: https://www.techradar.com/news/apple-might-be-slowing-down-y... And they have plenty of experience building walls around a garden. Ask anyone using OSX for the past 15 years and you will see how difficult it has become to write or publish software for Apple.

Alternate description of the same information: “newer upgrades made older devices batteries’ last longer”

They did nerf speed. But they did it for a reason. I get being mad about your phone being slowed down, but i don’t get being mad about it once you understand why.

Revolut stopped working for me on GrapheneOS with an official message "Sorry, Revolut is not supported on devices with custom firmware".

Do you have the sandboxed Play Services installed? It works fine for me on Graphene (just checked). That said, the recommendation I always give, and personally follow: keep a spare phone in a drawer somewhere, with official Android installed, a Google account, and use it exclusively for business purposes - banking, government services, and the email account you use for those (separate from the one you use for everyth…

> That said, the recommendation I always give, and personally follow: keep a spare phone in a drawer somewhere, with official Android installed, a Google account, and use it exclusively for business purposes - banking, government services, and the email account you use for those (separate from the one you use for everything else). Nothing else, no messaging, socials, browsing, or games.

Anything which doesn't support an alternative method (not involving a proprietary blessed google phone) of management should be illegal if it's government related and should be boycotted if it's not.

None of the unofficial Android builds allows me to access to the secure element in my SIM card to use my e-signature, which works with SIM menu prompts triggered OTA by the application I'm currently using, mostly governmental services. If I'm on a custom ROM, the notification never pops up.

That's not an attestation issue.

But have you checked if GrapheneOS handles it?

Anything that depends on the SafetyNet API will not run if your android build does not pass the checks, the list is much much bigger than "just google wallet". Whether a rom passes safetynet or not very much depends on what google considers blessed today, and what they will consider blessed in the future.

SafetyNet can be implemented by non-google-blessed ROMs (and is implemented by all non-google vendor roms without google's keys).

It works on GrapehenOS with their own keys (or you can, if you want, probably use your own keys).
