Printer LAN

LAN-only helper to view a Bambu Lab printer camera stream and monitor telemetry. The app generates RTSP/RTSPS URLs for local playback and lets you save/import settings as JSON.

This is not an official Bambu Lab application. Use at your own risk.

Printer Requirements (Bambu X1C)

To access the camera stream from the LAN, one of the following must be true:

• If firmware >= 01.08.05.00 (20250312) Developer Mode is enabled on the printer, which reveals the LAN RTSP/RTSPS stream and a per-printer code shown on the touchscreen.
• Or you are running an older firmware that still exposes RTSP/RTSPS without Developer Mode.
• For additional firmware information see https://wiki.bambulab.com/en/x1/manual/X1-X1C-AMS-firmware-release-history

Notes:

• The app’s “Bambu X1C” URL template expects the printer’s special (developer) code and the printer’s LAN IP address.
• Newer firmware typically requires Developer Mode for LAN camera access.

Risks of Enabling Developer Mode

Enabling Developer Mode relaxes some security protections intended for regular users. Typical risks include:

• Increased attack surface: extra services/ports may become accessible on the LAN.
• Network exposure: anyone on the same LAN who knows/obtains the code and IP could attempt to access the stream.
• Support implications: using undocumented/developer features may not be supported by the vendor and could affect warranty or support responses.
• Updates may change behavior: future firmware may alter, restrict, or remove these capabilities.

Mitigations:

• Keep the printer on a trusted LAN (or an isolated VLAN) and avoid exposing it to the internet.
• Use strong Wi‑Fi security and restrict who can join the network.
• Disable Developer Mode when not in use.

How To Enable Developer Mode (high level)

On the printer touchscreen, open Settings and look for Developer Mode (or a similarly named option). When enabled, the screen will show a special code. You will also need the printer’s local IP address.

The exact menu names can vary by firmware; consult your printer’s documentation or on‑device help if options have moved between versions.

Using This App

1. Open Settings (gear icon on the Stream Settings screen).
2. Select URL Format:
   • Bambu X1C: enter Special Code and Printer IP.
   • Generic RTSP: enter Printer IP (path is generic rtsp://<ip>:554/stream).
   • Custom: provide a full RTSP/RTSPS URL.
3. Save or Connect.

The app previews the generated URL for the selected format.

Import/Export Settings

• Import: Use the Import button (AppBar or footer) to choose a .json file. The app accepts both camelCase keys and legacy rtsp_* keys.
• Export: Use the Export button to save current settings to a .json file. A toast will show the save location when available.

Where Settings Are Stored

• SharedPreferences: basic key‑value copy for compatibility.
• JSON file: rtsp_settings.json inside the platform’s application support directory (mobile/desktop). On web, file I/O is skipped.

Platforms

• Android, Linux, Windows.

Disclaimer

This software targets LAN use only. Respect local laws, your device’s EULA/warranty terms, and your network security policies. You are responsible for any changes you make to your printer (including enabling Developer Mode) and their consequences.
