Thank you for the details.
It’s more in line with a video game console where you can choose to ignore the firmware/software update, but it’ll block you from using online services.
But again, go buy a Prusa. Prusa wont stop you from installing whatever firmware you want. Prusa isn’t trying to build a heavily integrated ecosystem. They pride themselves on making hardware that is open for you to do whatever you want with.

Most likely I am not the sharpest tool in the shed, or maybe it’s switching between 3 hot ends with 2 assembly’s as someone with limited experience. But I’m not even sure Bambu’s don’t need tinkering, I constantly have the allen key out and have to massage settings to reduce stringing or improve consistency in print quality across parts and nozzles.
But I do remember parroting the idea to a friend when I was picking Bambu that it was because I didn’t want printing to be the hobby over the things I was printing for, before seeing that same narrative repeated ad nauseum by consumers and realising I had totally absorbed the marketing. So they have been extremely effective in pushing that perception.
Prusa has been friend zoned

The firmware is currently in beta for only the X1. It does not come preinstalled on anything.
With LAN mode I’ll missing having the function to rate prints on Maker World.
I’m aware there’re multiple ways to support designers e.g. Patrion, ratings, boosts etc.
However I suspect not everyone can support through Patrion.
Boosts are limited and zero in LAN mode, I also have no idea how the algorithm is impacted by a low effort 
.
Majority of users will be click and print so this is small numbers so… .

I tried out your scenario to see if it breaks in a similar manner. I logged out of my account on my X1C and Orca. Blocked the MAC address and IP of my printer. Enabled LAN mode on my X1C and added it to Orca Slicer. I was able to send a print without any issues. Both Orca and X1C are on the latest versions. It may be an issue with how you are blocking it on your router? I made sure to only block from from Internal to External, curious if you are also blocking it internally.

If you have a LAN and internet access you do not have LAN only.

For me it is not so much about enforcing things or that Bambu makes a mess more often than not.
For me it is simply the issue that Bambu is too controlling and too focussed on a security system that has no actual benefit for any user.
I am printing since the days of the threaded rod Prusa and built my own printers, bought them and well, used them - without any issues EVER.
Be it through a preferred Ethernet connection or Wifi -only since I use Bambu connectivity and usability has become an issue.
Being forced to to set up the printer and Studio at least once a month because Studio refuses the access code or the printer no longer shows up in Studio…Doing a calibration should be easy and straight forward - but turns into a nightmare if Studio looses the printer and the entire calibration was for nought…
LAN only gives me all I need and this should just work always.
Just to be curious here : Does anyone here have any concerns someone could hack their way into your printer to do bad things???
Somehow I highly doubt that any normal user has a need for the bogus security measures Bambu imposes on us…

Good, Then so long as you never make an update mandatory we are good. If that change makes it OUT of Beta and into the firmware you are shipping I will not be buying any more of your printers. Shoot at the open source community at your own risk. Steve Jobs he is NOT.

Not really. But then again, bot farms and statistics on the thousands of online devices that have been hacked are a real thing. Which I have no doubt Bambu’s “authorisation control” will do… nothing to fix. 
But as long as I can still print my gridfinity organiser boxes and random odds and ends from the Bambu Handy app… Bambu can “spy” on me all they like. Oh, wait, they can’t if I turn off the wifi and just use the SD card!

Regretfully I have just bought a new X1 and now feel I want to return it and get a full refund. No one should accept this kind of control over how you use something you paid for and dictate what other programs you can use to make your prints.

Calling remote bricking, remote bricking would be more accurate. Take away lan mode and your company will burn. If it is ever made impossible to print without an internet connection I will never buy another bambu product. I may need to do that ONCE in the life of the printer but it is sold WITH that capability and removing that ability from our existing products amounts to theft, spiritualy if not legally.

I just found out about this entire controvercy after I hit the order button. If I had heard of it sooner I likely would not have ordered, I’d have waited to see just how this all shook out. Now I may spend the entire lifetime of the printer feeling like I have to defend it against the malicious intent of the very company that made it? Who the ■■■■ do you think you are? Apple? Or Microsoft? Think again.

Given the bad WiFi on those printers i will put a modem next to it connect printer wirelessly to it and and computer to that router when i need it.
I deleted bambu studio from the computer and handy app from the phone.
Then installed the Orca folowing the instructions on rossmangrop wiki site
Next is to apply for the Bambu companion app - test to see how it goes.
Most likely i will have printer on a wifi so i can access it with computer without connection to internet
Yesterday bought few nozzles & extruder for spare to use up the points i had on the account the closed it.
I imagine in few days I will not be able to connect to forum anymore ( not sure how i can be logged in currently since account is deleted- goes to shows how buggy bambu ecosystem is and not ready to be locking in customers in anyway)….

I know I often go hard on Bambu…
I say for good reason, you might say otherwise…
So let’s be fair here and try some comparison…
You probably have a mobile phone, which means you are either an Android users or a fan of half eaten apples…
You phone is useless without a matching account…
Trying to get rid of these requirements is made impossible and requires custom firmwares which on some devices will make it impossible to use certain things, especially those related to hardware based encryptions and security features.
Ok, you are aware of all that and more, paid attention to the T’s & C’s and also disabled all calling home-, improvement- and such features…
You might even use you paid VPN per default…
Well…
No matter what both Google and Apple go around your VPN simple because no VPN is secure unless it works on a fully rooted devices and with full root privileges…
Speaking of those terms and other bogus…
NO ONE reads these 20 odd pages - NEVER…
All we ever do is to click on the OK button, tick the box or if made hard quickly scroll through the text…
Same for you banking needs by the way and those hidden fess and charges LOL
Realistically Bambu WAS quite fair - until their X1 firmware got hacked and custom use made possible.
Another big blow where those nice tablets print farm users love so much…
Rather than supporting the customer Bambu decided to EXCLUDE them even further for actually owning their printers and deciding how to use them.
Marketing and the need for control is one thing but a whole different thing once the bogus affects the normal use of the printer.
So what COULD have been decided differently on the Bambu end ?
Security IS vital these days and some users do need remote access to the printer(s), some do need automation options, some do need real privacy and security to keep intellectual or design properties secured.
And yes, some do need all the integration with Makerworld and all…
But and that is the the big BUT here: Should ANY company be allowed to restrict how someone who paid to OWN a device can use it ?
In Europe the case is already made clear - not even custom firmware can revoke things like warranty or support for hardware failures…
In other market regions like AU or USA things are bit different.
And in all cases we still face the problem of software/firmware required to use a device coming with restrictions and limitations by default.
Legally the companies are doing nothing wrong, even in Europe this legal grey area stays active.
We can’t blame Bambu for trying to keep aftermarket solutions out, same for making it hard to get around restrictions like simply uploading a custom firmware that is free of all the bogus some people don’t need or would prefer to stay in control of.
Remove it all and those fancy Bambu printers are just like any other open source printer project out there.
Upload the firmware you like, modify what you like and be happy…
Would this mean or result in a loss for Bambu ?
IMHO the opposite would happen…
High temp engineering filaments are still a no go thanks to the all the plastic parts used inside and for the housing.
Still means it is a good value printer and well capable…
At least if we exclude all the pandemic price hiking…
Most people would still go for a Bambu printer, especially if Bambu would offer matching firmwares for user needs…
And those who would prefer a custom firmware would still be the exception not the rule…
Just saying…

Yes, and?
What I’m saying is that LAN ONLY, strongly implies that the printer should ONLY ACCESS THE LAN. I realize hitting a checkbox on your printer isn’t somehow going to change settings on your router. If your router is leaving ports wide open to the outside world, you have issues we can’t solve here anyway.
But honestly, never-mind. This whole conversation has gotten so convoluted with shills, conspiracy cranks and rampant pedants that the whole exercise should be locked before it collapses under the weight of it’s own toxicity. Nothing valued is here.

Not if you’re running Graphene OS (and probably a few others), which everybody can install and use, albeit only on a Pixel phone - and, yes, it’s super-easy, no need for any arcane knowledge. I was using SailfishOS before I was sufficiently convinced that I can keep a modicum of my privacy by switching to Android, which GrapheneOS finally convinced me of. Similarly, it took me a long time to convince myself that I can live with the restrictions that BL printers pose. I would’ve never bought a BL printer if I wasn’t convinced I can keep it from phoning back to the mothership, which is why this situation, or more a whiff of what’s to come, has me a bit riled up.
Mind you, I’m well aware that my stance on privacy and security is a bit fringe for regular folks - you kind of grow paranoid when you spend sufficient time on the cybersec side of the fence - and I’m fully aware that most people have given up on these concepts, which is why they are so ready to be bent over backwards and riled by tech megacorps for some temporary/illusionary convenience. I do, however, believe that winning even an inch in this ‘battle’ can have great benefits for the society which is why I’m still ‘fighting the good fight’.
If that’s the case, they need to run away from BL as far as possible. There is no privacy with the default mode of operation being to upload your prints to their cloud before they are delivered to your printer for printing. And security - what security? This latest controversy/debacle has clearly shown there is not even an ounce of cybersec expertise in whole of BL - with the goal of increasing security, they distributed private keys publicly for crying out loud, something that doesn’t even qualify as a rookie mistake, heck, ever ‘sheer incompetence’ is too mild of a qualifier.

It has been interesting and a bit entertaining seeing how a misunderstood line of code has morphed into whirlwind of silliness among the conspiracy minded.
