It's incredibly frustrating that the majority of devices today report usage to the mothership without the user's consent. Does firewalling the device cause any issues? A printer (of any kind) should not reach the open Internet, period.

All of these printers can be run completely offline, although then you obviously lose any network-related features such as sending prints over the network. I know that at least the Bambu printers (and I assume most others) can also be run in LAN-only mode, where they only work with devices on the same network. In this mode you could definitely firewall them without causing issues. The main features you lose by being in LAN-only mode are the phone app and being able to access the printer from off your network.

I second this. I run an A1 on a separate IoT wifi network that doesn't have outbound connectivity and using nftables rules for forwarding can send prints from my normal network with minimal fuss.

I did have to play around and use orcaslicer to get the printer set up using the network printing and camera feed working.

The one issue I do have is that it seems I would need to connect the printer to a internet enabled Network to get firmware updates, because the firmware version I have is ironically the one before they enabled SD card updating lol.

Back to the original question, I've had this printer for about a month and have been printing virtually non-stop with very minimal complaints. Coming from an ender 3 it is absolutely night and day in terms of ease of setup and general usage.

If the printer is functional, doing what you got it for, what do you need firmware updates for?

Lan Only works by making you use the Bambu connect software. If the Bambu Connect software isn't running, Orca cannot start a print job or control the printer. It doesn't sound too onerous, but it should be mentioned that LAN only wasn't added till users gave 'feedback'. I suspect the original intent was Bambu Slicer only.

It's the other way around. You can only connect to orca slicer or other programs if you are in LAN only mode. Otherwise you need Bambu connect.

Or just stay on the previous firmware version and you never need Bambu connect.

can't you use something like this? https://octoprint.org/

i have no idea if it works with modern ones but my "old" Ender 3 plays nice with it

Octoprint is still a great piece of software that works with most printers, but it's running into a dead end where streaming G Code over the USB Serial emulation isn't fast enough on the newest generation of printers to keep them printing at their full speed.

surely they can all be run lan only with a clever dhcp server that doesn’t give a default gateway to the device?
