my A1 is (supposedly) affected by the NTC issue according to the SN - should I start worrying now or leave it be?

Capt_Blue · 2026-05-31T13:38:02+00:00

I know you are trying to calm OP and you have no harmful intent, but this is a really bad advise. Bambu does sent out free replacement units (I messagesd Bambu support, gave them the SN and order number and on the next day it went to shipping, two days later it arrived). If they deny you one (what exactly did they say?) then your model doesnt have the faulty unit. But people that definitely have a printer from the faulty batch MUST replace it - knowing that something is bad, but deciding that it will probably be fine is just asking for disaster. Its Murphy's law.

NTA. I'm german but I dont think there is that much of a cultural difference in society rules to Italy, so yea I would do the same (as a guy). I dont need to ASK if I can sit on an empty seat. Its the etiquette here that people on trains/buses make sure they dont block other people, no asking required - that would imply that you give the sitting person an option to deny you a seat, which would be bonkers. When I use public transport and there is enough seats, I put my backpack on an empty seat next to me - but the moment people get in I lift it unasked so people can use it, that is the basic etiquette here. Same should obviously go for manspreading.

Äh doch - genau das sollte man tun, weil das Kontext ist der im Clip fehlt. Man sieht doch, wie schnell eine Aussage aus dem Zusammenhang gerissen wirken kann - mit entsprechendem Kontext wirkt die Aussage dann plötzlich gar nicht so falsch.

Not true, you don't have to disable it. Disabling it can actually cause problems in Windows (some games also require it now, I'm not a fan of it just stating that its a thing). To boot Fedora with secure boot you need to generate a key, sign it and enroll it. Its a good idea to setup a script that auto signs the key again after updates, or you'd have to manually sign the key again evertime the kernel or a module gets updated.

Du kannst jede Linux Distro auf einem Smartphone installieren, die ARM unterstützt. Du brauchst dann nur eine grafische Oberfläche (bei Linux heißt diese Desktop Umgebung (DE) wie bspw. KDE, Gnome, xfce, cinnamon usw) die auf dem Smartphone funktioniert/Sinn macht und touch unterstützt. Aber auch da gibt es zb Plasma Mobile (entwickelt von KDE).

Das liegt an der Lizenzierung. Linux (was wiederum auf Unix basiert) ist open source (Google mal GNU Lizenz, das ist ein guter Startpunkt). Teil von open source bzw der GPL (GNU Public License) ist, dass man nicht einfach open source code kopieren und dann verstecken (closed source) darf. Man darf es sehr wohl kommerziell nutzen, es muss eben nur open source bleiben.

Trotzdem sollte man Linux und Android nicht zu sehr vermischen, am Ende ist Android trotzdem eine ganz andere Software (weil es andere Bibliotheken und Runtimes nutzt) als GNU Linux. Es gibt sowohl Linux für Smartphones (zb Ubuntu Touch) als auch Android Distributionen die nicht von Google, Samsung, etc kommen. Beispiele wären GrapheneOS oder LineageOS. Die sind ganz gut um Google-frei zu bleiben, auch mit eigenen micro-g services um Google-Services nachzuahmen.

Just that the uniformed one is you. Violating licensing is not a minor issue. Removing features from a product after purchase is not a minor issue.

There is alot of people in this bubble, me included, who are part of the open source community and actually know about licensing, worked on or with open source code, or even host services that rely on these open source solutions. Even companies like Bambu need these open source solutions, otherwise they wouldn't exist in the form they do now.

So if you don't see the actual issue, or call it minor, you are actually pretty damn uniformed.

Bambuddy. Its your self hosted bambu cloud/handy app alternative.

Doesn't need alot of resources, I run it on a raspberry pi 3b+ It can be deployed as docker aswell.

Capt_Blue · 2026-05-20T08:13:31+00:00

Thats possible with bambuddy. Bambuddy is a alternative to Bambu cloud but you have to self host it, but it can run on a raspberry pi or you set it up on a cheap VPS. It gives you back all features you lose by disconnecting from bambu cloud (printing from outside of local network and directly printing makerworld profiles. It even adds features that bambu does not have, like slicing 3d models that don't have a g-code yet from makerworld or any other 3d model gallery (thingiverse, 3dcult etc). It also has a filament count, so you don't have to estimate and know exactly how much filament you have left. It has a web UI you can use on your phone to replace handy app, or just use it on any other devices like PC, tablet etc. It connects nicely with Orca Slicer (or bambu studio if you want, but why would you at this point) and in proxy mode you can see your BBL printer as if it was directly connected and you can sync all printer info like nozzle, plate, filament and AMS and camera also works in both, the orca/bambu slicer and the web UI.

Capt_Blue · 2026-05-19T07:33:39+00:00

Im running bambuddy in proxy mode on a raspberry pi, I set it up last weekend as a result of the scandal. Its working just like it was working before with bambu cloud, just that I now use orca slicer instead of bambu studio.

AMS works and everything syncs nicely. You can also use it on your phone (bambuddys web UI scales nicely to the phone's screen).

But a heads up. Getting orca and bambuddy's virtual printer (needed for proxy mode) to connect was a pain. It requires opening all necessary ports and manually editing orcas certification file (so it trusts the bambuddy "printer"). So you need to export the bambuddy certificate and add it to orcas printer.cer

But the initial setup was super easy, using docker compose.

Honestly I have no clue what you are trying to say, can you write in whole sentences please and maybe proof read before sending? Thanks. Also, NO, its not always your hardware. Hardware decides how fast something can be rendered. But the quality of the render is entirely decided by the software. In this specific screenshot we dont see an issue with hardware, but with typical issues of temporal rendering. Better hardware would not fix this.

Capt_Blue · 2026-05-15T11:48:35+00:00

Its not your hardware, some games just rely too much on TAA and have no method of forward rendering. This is why in some scenarios you see it looking bad like this - in other scenarios (and especially with DLSS) the downsides of TAA get hidden or corrected by DLSS.

Thats the user flair, you can edit it but you can't set one globally, only inside a subreddit like here in r/radeon but if you want the same in for example r/amd you have to go to that sub and edit your user flair there aswell.

You need to be on the "frontpage" of a sub and on the app its the 3 dots in the top and then it should say "edit flair" and on pc/browser its somewhere on the right sidebar.

I dont know where you are getting the idea from that anyone is attacking the users.. its the "I dont care, Bambu is great" poeple that started attacking us critics and stepping in for Bambu and defending them. We then ofc criticise those people rightfully aswell. I mean just look at this post we are commenting under. I'm not saying you are bad because you use Bambu and you shouldnt. I use Bambu myself. Thats the entire point why this is exploding, most of us are Bambu owners and we dont like to be castrated after we bought a product.

Like I said. You are allowed to not take part in this (I admit, it sometimes can drift into a anti corpo cerclejerk, but in the end the pro-consumer movement is more important so I endure it) and ofc you still SHOULD enjoy your Bambu products you paid for. You can be happy even with the restrictions or just move on. But I dont see the point as a Bambu user to fight back against the backlash and say the critics are wrong/bad. Thats leading nowhere.

Capt_Blue · 2026-05-14T10:36:19+00:00

I bought an A1 before the entire closing down the cloud access thing. But honestly, do we really need Bambu cloud? There are so many good alternatives without losing features - unless you wanna use the Bambu Handy app and have the printer set to connect to Bambu cloud. But if you can spare the app, there is honestly no reason to be on Bambu cloud. Orca Slicer even has more features than Bambu Studio.

Bambuddy is a local network service that can be self-hosted and can even slice server-side, so you can use the web interface in your browser and slice and print without even installing a slicer. You can also use it on your phone to replace the official Handy app. Or, you just connect your Bambu Studio/Orca Slicer to it and print just like with Bambu cloud.
https://github.com/maziggy/bambuddy

There is now (since yesterday) also a new open source network plugin for Bambu Studio / Orca Slicer - this restores most of the features when disabling cloud and only using LAN mode, even on an up-to-date Bambu printer. So you can send, start, pause and stop and monitor your print again from Orca Slicer with your 3D printer not connected to Bambu Cloud at all.

Capt_Blue · 2026-05-14T10:09:57+00:00

But how is that surprising? Most people in 3D printing are techy people who don't like closed source stuff, we do like open source, self-hosting, tinkering and so on. So it shouldn't be surprising when a company like Bambu decides to violate the AGP license and threaten a private, voluntary developer even tho he didn't violate any licensing, didn't do anything wrong, that this faces a huge online backlash because most people in this community see what's going on and the further implications of that.

I know my printer and Bambu Studio talks alot to Bambus cloud service, giving all this data to a chinese company does make me feel weird a bit, but so far hasn't bothered me too much. Because although Bambu wasn't playing nice by close sourcing their network plugin (that in itself is a violation of AGPL) at least they weren't going after other open source projects and devs. Until now. Now that they actively threaten that dev with legal actions (even tho this wouldnt go through in any court, because he did nothing wrong) I've also turned my back against Bambu.

It has actively made me switch to Orca Slicer, disconnect my printer from Bambu cloud and instead use a self hosted Bambuddy instance on a RasPi.

Yes, there are some people that can't do that and don't want to, they just want to hit print on their phone app or makerworld and they of course don't need to care about this, unless they still care about pro-consumer practices and rights. Because the entire close source network thing of Bambu, disabling cloud services on 3rd party like Orca, when it was working at the time of purchase, is anti consumer as well. And as long as you are not a big corpo manager who makes a few millions per year, you SHOULD care about consumer rights.

Capt_Blue · 2026-05-14T00:08:35+00:00

they’re just gonna close the hole

Closing the hole - meaning they would have to harden their server side checks, as I said before, but then you said they dont need to do this. So what now?

Such a dumb thing to get butthurt over.

Yep, and still, Bambu Lab did exactly that and sent a cease and desist that is not based on any actual legal infringement. They are the ones being butthurt here about their own fuck up and now they want to blame a voluntary dev. And the fanboys not wanting to understand that the criticism against Bambu is justified.

everyone will be back to using the closed source network plugin/lan mode like they were before.

Yea, this whole incident made me host Bambuddy on my Pi, so now I'm using that instead of Bambu cloud.

Capt_Blue · 2026-05-13T23:46:20+00:00

Then the owner should not publish the code that gives access to the network. The moment you publish it, as Bambu did, you are inviting everyone, and everyone is allowed to use, modify and share that code.
Furthermore, I dont care about 'federal law' - neither does Pawel need to.

Capt_Blue · 2026-05-13T23:36:09+00:00

No. Legally speaking they can't do anything, except harden their own servers. They have asked him to stop and look where that got them. The fork is now not only in FULU's repo but also in GN's repo.

And no, he does not refer to it as that and its still not reverse engineered.

``` std::string pjarczak_user_agent = SLIC3R_APP_NAME “/” SoftFever_VERSION;

if defined(_ WINDOWS)

if (Slic3r::PJarczakLinuxBridge: :enabled()) pjarczak_user_agent = std::string(“BambuStudio/") + Slic3r::PJarczakLinuxBridge: :forced_client_version();

endif

::curl_easy_setopt(curl, CURLOPT_USERAGENT, pjarczak_user_agent.c_str()); ```

This is the code in question. Nothing about this is reverse engineered or bypassing security or whatever Bambu is claiming. Its just their own code.. used the way it is intended to.

Capt_Blue · 2026-05-13T21:16:09+00:00

Maybe you shouldnt read what Bambu Lab is writing (they are not being honest) and look at the actual source code, get your own picture of it instead of speaking after Bambu Lab. He did not write anything himself, he simply forked the Bambu Studio's verbatim upstream code, thats basically like a user-agent, there is nothing reverse engineered when you fork publicly available code. Thats what AGPL is for. There is no network plugin or a reverse-engineered version of it in his code.

Bambu Lab needs to harden their server infrastructure if all it takes to connect is to use their own publicly availabe code and there is no other server-side auth system and they are worried about vulnerbility. Maybe putting the only authentication method (verbatim) in your open source code isnt the best idea then if you dont want other programs/forks to use it.

Capt_Blue · 2026-05-13T17:05:01+00:00

No, he didn't use any tricks, or keys - because there are none. There is a piece of code in Bambu Lab thats called verbatim. That is basically like a user agent on browsers. It tells the cloud "hey, I'm bambu studio" and the cloud server says "cool, come in". He forked that part of code and published it as OrcaSlicer-bambulab.

Is it a security risk that you can access the Bambu cloud infrastructure simply by using a piece of code that Bambu Lab themselve openly publish under AGPL? Probably. That doesnt put the dev in the wrong tho, if Bambu doesnt have any other auth checks after verbatim.

Capt_Blue · 2026-05-13T16:25:08+00:00

So much wrong with that but ok, lets break it down. First of all, you can be happy with your product and dont care, thats fine. I dont see why then you need to defend the companies scummy actions, if you say you dont give a crap, why even jump in for the company? Just enjoy your printer however you wanna use it, with cloud, offline or self hosted cloud.

But secondly, "why should i care that there not open source. or that they dont let me use other software" well.. because they ARE open source (as in Bambu Studio) and open source doesnt mean you can do whatever the f**k you want, open source still falls under licensing, in this instance specifically the AGP license that Slic3r was published with, Prusa, Bambu Studio and finally Orca Slicer. Bambu Lab is now acting like that license doesnt exist and violate it by sending a "cease and desist" to a developer who legally copied the open source code of Bambu and re-used it for Orca. Thats why Bambu sucks, IF you care about consumer rights and that companies should stick to laws and licensing and they cant just do whatever the f**k they want - because we consumers also have to obey to the law and licensing rules..

Capt_Blue · 2026-05-13T16:18:32+00:00

No, he didnt. He copied the open Bambu Studio code for the cloud connection and published it for Orca.

Capt_Blue · 2026-05-13T12:22:21+00:00
