Editing Bambu Lab LAN mode guide

Hi everyone, I just thought I'd share my experience with using my P1S offline and blocking its access to the internet from your router (just in case Bambu Lab decides to do something about all the users refusing to update their firmware and disconnecting from their cloud).

I have a P1S with the 01.07.00.00 firmware and an AMS with the 00.00.06.49 firmware (both latest at the time of writing, I performed the update via the internet when I first got my printer one month ago).

# I turned on LAN only mode using Bambu Lab's guide: https://wiki.bambulab.com/en/knowledge-sharing/enable-lan-mode . Basically you go into your printer's settings, scroll to LAN only mode and set it to ON. This logs you out and supposedly disconnects your printer from their servers, but since it is still connected to WiFi it theoretically could call home if it wanted. We'll take care of that in step 5. [[File:P1S.jpg|none|thumb|Turn on LAN only mode by selecting it and pressing Ok, then pressing Yes on the confirmation dialog that appears]]
# I uninstalled both the Handy Android app and Bambu Studio, I won't be using those anymore.
# I downloaded Orca Slicer 2.2.0 (latest at the time of writing): https://github.com/SoftFever/OrcaSlicer/releases/tag/v2.2.0 . After you follow the link scroll down to the bottom of the page to the Assets section, and pick the right one for you operating system.[[File:Orca download.jpg|none|thumb|In my case I chose OrcaSlicer_Windows_Installer_V2.2.0.exe]]Then I installed it, opened it, installed the Bambu network plugin (no way to use the printer remotely without it yet :( ), did '''not''' log in with a Bambu Labs account and went to the Device page. Top left corner click on the "No printer +" text and select your printer. With my P1S I still have full functionality ('''including live view'''). [[File:Orca slicer 2.2.0.png|none|thumb|Orca slicer and my LAN only printer]]'''Important Note:''' After everything is working remember to turn on Stealth Mode so that Orca won't attempt to communicate with Bambu's cloud.[[File:Stealth mode.jpg|none|thumb|Click on the hamburger menu in the top left -> Preferences -> Network enable stealth mode]]
# I got my printer's MAC address from Settings -> MAC (scroll all the way down).  (Fig. 5)[[File:P1S MAC.jpg|none|thumb]]
# I went into my router's settings (this depends on your manufacturer, send me a DM if you are not sure how to do it), parental controls and added a new rule based on the printer's MAC, to permanently disable its internet access. (Fig. 6)[[File:Router.jpg|none|thumb]]

And that's it, you have a completely offline printer, that can't access the internet and that you can monitor and view from within your network.

[[File:Parsec.jpg|thumb|Screenshot from the Parsec Android app. I can monitor everything and cancel/pause printing by pressing on the buttons]]
If you still want to print remotely there are several possibilities. You can use Parsec (if you have a Windows or macOS machine on the printer's network) https://parsec.app/ to connect from your phone / laptop remotely to your local machine without setting up anything else network wise.

You just install it on both your host (machine connected to the same network as the printer) and you phone/laptop and you can use the home machine as if you were in front of it. I even use it to play games, it's got very low latency.

You can also set up a personal VPN using something like https://tailscale.com/, and then you can connect to the printer from your laptop even when you're away.

You can also use remote desktop connection, but I find it's wonkier than Parsec. This video https://www.youtube.com/watch?v=wYW37thazo0 explains how to do so.

= Conclusion =
Although using the Handy app was easier, I always felt a bit queasy at the idea of all of my prints going through their cloud. This latest 'security' update was just the last drop for me. Using this short guide YOU maintain full control over YOUR printer, and nobody else gets to see everything you print. You can even upgrade the firmware offline if you so chose https://wiki.bambulab.com/en/p1/manual/P1-firmware-update-from-SD-card . At the end of the day, their printers are amazing machines, especially for the price point, and I can live with the compromise of using LAN only mode with parental controls to ensure I maintain full control over mine.

I've created a GitHub repository with all the current firmware files and network plugins, both those installed on my computer that work right now and the current versions from their CDN: https://github.com/Tzeny/bambulabs_plugins_firmware . Feel free to make a PR to add your own currently functioning plugins and firmware.
