Bambu Lab cloud

Connect Bambu Lab cloud

Connect your Bambu Lab account once as a Bridge service, then add printers from that account without pasting the token again for each machine.

This is optional. You can skip it and add printers with Standalone / LAN only (Bambu LAN, OctoPrint, or Moonraker).

What you need

  • A Bambu Lab account with one or more printers linked in Bambu Studio / Bambu Handy
  • A cloud access token from that account (not the printer’s LAN access code)
  • The correct cloud region: Global or China

Get a cloud access token

Bambu Lab does not show this token in normal account settings. The usual way is to copy it from your MakerWorld browser session.

  1. Open MakerWorld in a browser and sign in with the same account you use in Bambu Studio:
  2. Press F12 to open developer tools.
  3. Open the Application tab (Chrome / Edge) or Storage tab (Firefox).
  4. Under Cookies, select the MakerWorld site.
  5. Find the cookie named token.
  6. Copy the cookie value only (a long string). Do not include surrounding quotes.

Treat the token like a password. Anyone with it can access your cloud-linked printers. Do not paste it into issues, screenshots, or chat.

Tokens typically last on the order of months, then you must copy a fresh one the same way and update the service in Bridge.

Cloud token vs LAN access code

Connect the service in Bridge

  1. Open Bridge and go to Services in the top nav (/ui/setup?kind=service).
  2. Fill in:
    • Display name — any friendly label (default Bambu Lab)
    • Cloud access token — the MakerWorld token value
    • Cloud region — Global or China (must match where the account is registered)
  3. Save / connect. Bridge verifies the token and lists printers on the account.
  4. After a successful connect, Bridge shows a connected summary. Use Disconnect only after you have removed any printers that still reference this service.

Add printers from the service

  1. Open Printers → Add printer.
  2. Choose Cloud via service.
  3. Pick the Bambu Lab service and a device from the account list (serial is filled in for you).
  4. Save. Each Bambu serial can only be added once.

Details and next steps: Add a printer.

Troubleshooting

  • 401 / unauthorized — token expired or wrong; sign in to MakerWorld again and copy a new token cookie.
  • Wrong region — Global vs China must match the account; try the other region if listing fails.
  • No printers listed — confirm the printers appear under this account in Bambu Studio / Handy, then refresh by reconnecting or re-saving the service.
  • Cloudflare / 403 — wait a moment and try again; Bridge retries with browser-like requests when possible.
