Bambu Lab, PLEASE MAKE A FULLY FUNCTIONAL LAN ONLY MODE! We know this is possible because our paper printers have been fully functional in this mode for over a decade.
We know that you want to see and use our data. We know that internet mode gives you access to our printers, and possibly the rest of our networks if we’re not careful. However, we have purchased your product with certain promises. One of these promises was the use of the Handy app. Another was access to our SD card files via Bambu Studio. Those promises are broken when you hamstring the software in LAN Only mode.
Please fix this code so that we who chose to remain private can still use the software that you promised us when we purchased your machines.

Curious what doesn’t work in lan mode, besides the handy app, obviously.
While I feel your pain. You’re user number 100,001 to complain about some aspect of this. I’m somewhere around user number 20,001. 
Unfortunately, Bambu doesn’t read these forums nor do they care. Based on their inaction on this topic, it’s clear that they think their product doesn’t need improvement and you better damned well love it or go elsewhere. 
All kidding aside. Bambu allegedly has a more robust implementation of their network stack in the X1E which has Ethernet. But there have been so few sold that there is little discussion on that topic. But even so, it supports your contention that his is possible and the fact that they just ignore us is an indication of how much of a priority this is for them.
Just know this, they have your money now and that’s all that mattered to them.

Also:
- No automatic syncing of presets between computers or between OrcaSlicer/Studio.
- Firmware updates must be done with download to computer and transfer to SDcard.
- No access to Timelapse or Models on the SD card from Device page in LAN mode, though FTP still works.
So, just a few inconveniences, since there are other ways to achieve the same results.

Didn’t they promise browsing files in lan only mode back in August 2023? It’s nearly 2025 and here I am using winscp.
This stuff, along with their new promise to cutoff access via firmware to 3rd party slicers makes me really start to regret getting this machine. Is there any way to retrieve files from the printer in LAN mode separate from their awful ecosystem?
I’m using mine via LAN only.
I’m not sure exactly what it is your missing. Someone’s made a list of things you’d not have the ability to do, all of which is pretty obvious without the internet.
I am one of those privacy nerds, and just took receipt of a new P1S. It’s only had access to the internet for the firmware update a few days ago, and it’s been offline since.
Through firewall rules, I’ve blocked access to the internet of all my printers (2D as well as 3D), and set up a Wireguard server so I can VPN home if I need access.
The reality is, you’ll lose all cloud features without access to the internet - that’s a given. The only thing feature I can think off that could work on LAN only mode that doesn’t would be the Handy App whilst you’re on the local network (Or VPN’d in) - but as I don’t trust that either and so I don’t use it, it makes no difference.
What do you mean by “fully functional LAN only mode”?
Also, if this is something that concerns you, perhaps backup the current version of ORCA Slicer and the LAN connect plug in so you don’t inadvertantly update to the new ‘locked down’ version of the firmware that is coming our way.

By fully functional I mean use of the Handy app while at home, and the ability to see and modify the SD card contents from both Handy and Bambu Studio. This would be a simple fix, except that their whole model is based on using their cloud and, with the latest news, it doesn’t seem like they’ll be moving away from that model any time soon.
Don’t worry, I’m still using LAN only mode, I’ve purchased a $20 security cam so that I can watch the print remotely to make sure it’s not going to hell.
p.s. These are features that HP printers had 10 years ago. They aren’t hard to implement, nor are they Earth shattering technology!
Oh, I completely agree with the sentiment.
I wouldn’t trust anything from them anyway, besides the low cost and great performance for that cost.
The new update does leave a sour taste in the mouth too.
It reeks of vendor lock in.
I’m happy without the handy app, but I agree and realise not everyone’s the same, this move to a locked in system just stinks.
I’d imagine it comes off the back of ‘made in China 2025’ or some other long term strategy. Although that just might be me not putting my tin foil hat on correctly.
Sorry for the delay. Yes, you can access all your files from the SD card. They’re all on there in simple formats that you can drag and drop onto your laptop.
I am reasonably happy with Lan Only mode.
It does what I expect and knew from my not so smart and not so fast printers.
But of course if something is possible I sometimes wonder why it is made intentionally impossible…
Tried to work out how all this stuff in Lan mode comes together and I guess that at least below the X1 level Bambu just tried the Chinese way.
If it is just enough, just good enough than we won’t invest a single cent more to make it even better.
There was/is the MTTQ stuff for certain things, the video feed, the status events and the additional printer controls Studio offers…
In the prepare tab we can do some things, in the device tab we can see the video and do other things - why not keep all controls and such in one place?
Simply because Bambu uses different ways to communicate.
Like relying on X11 protocol a lot and using Agora for the Video stuff.
Some low level things work over the broker, others only over the Network plugin.
You get the approach ???
A little box of code here, another one there and with just a few lines of code you whack them together.
And that in rather smart ways to ensure the flimsy CPU in the printer won’t go up in smoke LOL
COULD we we have SD access, video, timelapse control and all the rest that isn’t Makerworld and such working together in Lan only mode?
Not a problem at all, same for Handy being fully functional in Lan only.
The beauty of doing all through modules, libraries and such is you can define what goes where, when and why.
Functionality matters these days.
You don’t get a big 4K TV to only watch you old Super8 home reels on it…
And if you buy a screwdriver set you don’t want to find only flat heads inside…
But you had to buy a 3D printer…
With so many hackers everywhere there should be one or two making sure we get what we ‘need’ ??!!
Nope…
See it this way> A hacker not only needs a target but also a reason.
If the hacker has no interest 3D with Bambu he or she will never get the idea to give Bambu a hard time…
But since there MIGHT be one Bambu made sure they will have a hard time.
Like so many other companies Bambu has no problem working with hackers in the form of competitions and ‘compensation’.
Find a security hole, backdoor or such, report it to us so we can fix it and we PAY you for your time and hard work…
Depending on the level of risk companies pay quite nice sums to those ‘ethical hackers’ out there.
How the heck (hack) does this all add up ?
On one side Bambu works very hard to close up what they think needs closing and even pay hackers who report things of concern to them.
Making it rather hard to find a hacker with an interest to ‘help us’ for free - well done Bambu.
On the other side we find public and private keys in plain text and they can be extracted in full with ease…
And their calls are easy to find and change as well…
So why not just make your certs and tokens to keep Bambu out for good?
For the same reason you won’t just crab those certs and tokens, whack up a few lines of code and get the egg laying woollen pig…
Literally everything is secured by at least hash checks.
Means you have to change a lot of code in a lot of places, most of which are in encrypted files…
So you obtain even more keys and tools to either reverse engineer the code or to study what it does in a little helper tool so you program something from scratch.
Did all that ?
Well done indeed - you just wasted probably a few weeks and the new Studio version and firmwares changed a lot…
You won’t catch up…
We can use tools like WinSCP to access the SD card in Lan mode.
But to get these alerts and notifications from the printer you would have to get really creative, same for having a video feed in VLC or such.
