I added this page that is a copy of my Reddit guide. I need some help with formatting as I can't seem to get rid of the empty lines between the images and text in the first section
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).

Notice: This Article's Relevance Is Under Review
This article has been flagged for questionable relevance. Its connection to the systemic consumer protection issues outlined in the Mission statement and Moderator Guidelines isn't clear. Articles that focus on isolated incidents, personal disputes, or local matters may not meet the inclusion criteria for the Consumer Action Taskforce Wiki.
Why This Article Is In Question
Articles in this wiki have to meet the following criteria:
Systemic Nature: Demonstrate a broader pattern of systemic abuse, negligence, or policies that align with modern consumer exploitation (e.g., ownership revocation, barriers to repair, privacy violations, changing the terms of the sale after the sale).
Relevance: Relate to consumer protection issues that extend beyond individual grievances or localized problems.
Evidence: Provide verifiable evidence or credible sources to support the author's claims and demonstrate systemic impact.
Examples of articles that do not meet these criteria:
A single negative customer experience; with no evidence of systemic issues or company policies enabling such behavior.
Localized disputes, such as a bad experience with a contractor or small business, better suited for platforms like Yelp or local consumer protection agencies.
Complaints that focus on personal dissatisfaction (e.g., "I waited too long for a response") without tying the issue to broader consumer exploitation themes.
How You Can Improve This Article
To justify the relevance of this article:
Provide evidence demonstrating how the issue reflects broader consumer exploitation (e.g., systemic patterns, recurring incidents, or related company policies).
Link the problem to modern forms of consumer protection concerns, such as privacy violations, barriers to repair, or ownership rights.
Add credible sources or documentation that substantiate claims and connect them to systemic practices. i.e:
A company that takes 5 days too long to refund a deposit is a bad Yelp review. Not eligible for inclusion.
A company with 500,000 active repairs at any given time that purposely delays all deposit refunds for a period of five days, in order to invest/gamble with these deposits on their balance sheet, with verifiable hard proof from internal communications that this was an intentional & standard practice performed with malicious intent is eligible for inclusion.

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. 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.In my case I chose OrcaSlicer_Windows_Installer_V2.2.0.exeThen 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). Orca slicer and my LAN only printerImportant Note: After everything is working remember to turn on Stealth Mode so that Orca won't attempt to communicate with Bambu's cloud.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)
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)
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.
Remote access
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.
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.
Q&A
If you have any questions please leave them in the comments or as a PM and I will update this post with the answers.
Orca Slicer error 4020 Can't upload file to FTP server, this can happen for 3MF files, you have to export the objects as STLs and import then into a new project: https://www.youtube.com/watch?v=lWDNa2Pytlo
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.
