To Bambu Lab: thanks for the 10/10 hardware. We'll take it from here. You're no longer involved.

A fork of Bambu Lab's BambuStudio that brings back the Storage browser and print-from-SD when the printer runs in LAN Only Mode.

The official build disables SD-card access as soon as the printer is in LAN Only Mode. The Storage tab only shows "Browsing file in storage is not supported in LAN Only Mode.":

This fork talks to the printer's built-in FTPS server and local MQTT directly, so you can list, preview, download, delete and print the files on the SD card, no cloud or internet required:

• Browse / download / delete Timelapse and Model files over FTPS in LAN Only Mode, with real thumbnails and a local cache.
• Print from SD over local MQTT: the project_file command is published directly with an ftp:// URL the printer resolves itself, instead of the cloud-only path that fails in LAN Only Mode.

Don't trade freedom for so-called security.

It makes a convenient excuse for keeping control over how a product is used, but forcing people to export their data and to expose more and more hardware to the internet has never been about security.

A machine fully disconnected from the internet will always be more secure than one that isn't.

How are the most sensitive projects handled? On an internet-facing cloud? No. On a local network, completely cut off from the rest. A smaller attack surface means lower risk.

You don't need to lock your door if you live on the moon.
