Your access code and IP address

The access code

The access code is the printer's password for local connections. Bambu Studio, OrcaSlicer and Bambu Bar use it to sign in to the printer on your network, in cloud mode and in LAN Only mode alike.

Treat it like a password: anyone on your network with the code can read the printer's status, and with Developer Mode on, control it. Don't post it in forums or screenshots, and never type it into a website.

The IP address

The IP address is where the printer is on your network. You need it when an app can't find the printer on its own, for example across a mesh network or when discovery is blocked. Besides the printer's screen, your router's list of connected devices shows it.

If the address keeps changing, give the printer a fixed one with a DHCP reservation in your router's settings.

Use them in Bambu Bar

Usually you don't type either:

• Bambu Bar finds printers on your network by the announcements they send.
• If Bambu Studio or OrcaSlicer on your Mac has used the printer, Bambu Bar reads the access code they saved. It only reads their settings, never changes them. The Mac App Store version asks you to choose the slicer's folder once.
• Slicer on another Mac? Drop that Mac's BambuStudio.conf onto the setup page.

Otherwise:

1. Choose Enter address manually and type the IP address from the printer's screen. Bambu Bar reads the serial number from the printer.
2. Type the 8-character access code.
3. Click Connect.

Bambu Bar stores the code in your macOS keychain and only ever sends it to that printer, over an encrypted connection that checks the printer's certificate. Removing the printer deletes the code from the keychain. See the privacy policy.

When the code changes

The access code changes after a factory reset, and when it's renewed on the printer. Apps then show Access code rejected or can't connect:

1. Read the new code on the printer's screen.
2. Enter it in Bambu Studio and in Bambu Bar. If your slicer already has the new code, Bambu Bar offers to use it.

If the printer got a new IP address instead, Bambu Bar follows it on its own, from the printer's announcements.

Still can't connect?

The code and address are only part of it: the Mac and the printer must be on the same network, and macOS must allow local network access. See Bambu Studio not connecting and getting started.
