RE: Asked about opinion for bambu vs Prusa Core

   I know a guy who  is a Bambu guy, he doesn't like Prusa. I like to assembly myself, not himself; he wants to open it out of the box and get going. 

You should have said: I know a guy who cares more about printing than printers.

has nothing to do with Bambu.

Assembly is definitely not the reason why he "doesn't like prusa". He could just as well bought assembled prusa printer and it would also be "open it out of the box and get going". That's why prusa offers both versions. Me - what i don't like on Bambu is they doesn't have kit version, only assembled.

Some of users like to assemble, some don't. I'm technician by heart, so i want to know in precision what's inside each and every box / machine and how it works,  so i can easily repair / modify if anything goes wrong. That's why i rather assemble it myself. And things can and do go wrong - on Prusa or on Bambu.

Although core one is my third prusa printer i wouldn't call myself prusa fan, so I'd say my next printer will probably be the one which will first use indx system (and have at least 4 colors).

Yep. 100%. I know the Core One mechanics intimately now (since I've had to do lots of tweaking). If something goes wrong then am pretty confident I can repair it myself.

I know many users don't give a damn about this sort of thing. I think everyone damn well should.

RE: Asked about opinion for bambu vs Prusa Core

Concur.  Security is a huge concern with printing on a Bambu.  I don’t like printers sending my info to a building in the US, much less China.

RE:

That’s factually wrong. Offline mode, plus a firewall (a security mindet person runs anyway) fixes all security concerns.

So far most people talking about security concerns are clueless. And spread miss information .

Which completely misses the point that what you suggested is even actually necessary.

RE:

No, also wrong. We are in 2025. We have smart IoT fridge's, microwaves, security cameras that are in itself not secure. Shit doesn't need to be on the internet especially when security is priority #1

That things that aren't supposed to be online are not online is the default. Your Prusa printer shall not be online either. Anything that is online that doesn't need to be, is a security risk.

As said. Most people making statements about security, online security, know nothing, literally nothing about online security. 
To keep it simple: Stuff that shall not be on the internet, shall not be on the internet. A 3d printer is in that category. Any 3d printer! If security is a concern! Else we are doing bullshit miss information, by people who don't care about security, or simply don't know.

But isn't that the point? Bambu expecting you to put your printer on the internet by default, and expecting you to use "developer mode" (or whatever the slightly obscure name is) to run it locally -- while Prusa are taking a less pushy approach?

Utter nonsense. I don't buy Chinese printers and can just relax.

RE:

No. Not nonsense. These devices are not secure by default. Don't bloody put them on the internet. Don't use the same Email on any login. All such things are vulnerable.

Even if you choose based on feelings to trust Prusa, others who are not Prusa have access to Prusa systems. It's silly to have this conversation. So I will stop after this.

You have no clue how online security works. Things like 3d printers are not allowed on the internet, if security matters. end of the conversation. There are no exceptions, for when security matters. Same for other IoT devices, security cameras, fridges, and crap like that.

Utter nonsense.

RE:

Developer mode is another optional thing. That's to talk to 3rd party slicers like orca from a bambu. That's not related to security.

Offline / Lan mode is to have it offline. That's the one that matters for security. + your professional hardware firewall blocking it.

Ah, right. The two modes are tied at the hip, but the other way round -- when you want developer mode, you must also fall back onto LAN mode. Potentially annoying, e.g. when you need developer mode just to run you Panda display, but not security-related.

RE: Asked about opinion for bambu vs Prusa Core

Truth is, most folks will take convenience over security - sad but true.  They want the easiest and most convenient way to make something work.  If your so concerned, install card readers with two factor authentication with passwords/passphrase and biometrics to use if you all are so concerned that big brother is watching us print the silly things we print - excluding the fact that most of us pull all files from Printables (online) before sending to the printer.

As a regular user (which most of us are), we are not producing military grade items or proprietary things on these printers.  So I think this is really a mute point.  Good conversations but nothing to truly worry about as again, the printer is just the tool that makes the item we created on our computer.  If you have a stand alone computer working in a vacuum, then use Prusa as you can remove all networking from it or better yet, a much older Prusa model before they even installed the wifi capability to it - again, that is your right and choice as a maker.  

RE: Asked about opinion for bambu vs Prusa Core

I wanted to circle this conversation back to the original topic.  WOW, did you all see that Prusa and Bondtech partnered for the Core One INDX.  It just dropped yesterday.

https://blog.prusa3d.com/introducing-the-indx-fast-and-affordable-8-material-printing-exclusively-on-the-core-one_125242/

This changes things vastly in this thread, as before this point we had the MMU3 which is more of a cumbersome color changer (I have one so I know).  The XL was the only real material changer as it holds different materials in each toolhead (but was very expensive), now with the INDX on a Core One or Core One L, that does the best of both worlds color and multi-material at a lower price point than the XL. 

It looks like Core One folks can buy the kit from Bondtech and upgrade their Core One to support INDX, and later this year they will drop the Core One INDX directly from Prusa.  I'm really looking forward to seeing these in action and what those price points or options look like.  

So back to the original conversation, with INDX coming out on Core One's, this now has a HUGE potential to be way better than the Bambu H2D and lower or similar cost.  So this in my opinion puts them back in the game with their direct competitor.   I'm highly interested in getting a Core One L with INDX - once they become available.  

RE: Asked about opinion for bambu vs Prusa Core

I use my printers as a hobbyist - not to print top secret models. I don't really care if someone in China wants to see which pen holder I'm currently printing. I like having the remote features enabled, and will continue to do so.

RE: Asked about opinion for bambu vs Prusa Core

I want to be able to maybe print parts that can handle extreme situations so the INDX helps; I know someone who will be very amazed compared to their Bambu's.

I know many users don't give a damn about this sort of thing. I think everyone damn well should.

This article is simply targeted to consumers, even it talks about military.
The example with military drones - guess what, they need a connection to be controlled remotely. And this connection is a lot more tricky (security, redundancy, etc.) than our printer connections.
So those companies need a deep technical knowledge about remote communication and if those companies do not manage to put a networked printer in a separate subnet and isolate it from the www - they are completely wrong in their job.

Btw, you do the same (isolate production machines) also if you live in UK and buy UK built machines. So this has nothing to do with China.
And if you are a responsible producer you would also isolate Prusa's printers because even Jo and his company will most likely not mean bad - there are so many (supply chain) attacks all over the world that basically no one can say for sure that a company has not been infiltrated (even air gapped can be attacked - just remember STUXNET).

So this article is a big bunch of buzzwords and spreading fear where you - if you are a responsible company - will not treat a Prusa printer different than a Bambu printer in regards to network security.

RE: Asked about opinion for bambu vs Prusa Core

Rather short-sighted.  What if they steal your wifi password and use it to hack into your computer and steal your banking info?  Sending your print file to China to slice is not needed, so why do it at all?  I do not like the concept of sending any of my data to China, especially since I do not know what or why.  

I know what I said is outrageous, but is it really?
