How to find your Bambu Lab IP address, seri...

Printer Tools connects to a Bambu Lab printer locally with three values from the printer: its current IP address, serial number and LAN Access Code. They are not interchangeable, and copying a value from the wrong screen is a common reason for a connection that never completes.

Collect the values from your own printer while it is connected to the intended network. Menu names can vary slightly by model and firmware.

Printer Tools

All your 3D printers in one dashboard

Monitor Bambu Lab, Klipper, OctoPrint, Creality, Snapmaker, Anycubic, Flashforge, Elegoo, and Prusa printers from one app

Available on Android, iPhone, iPad and Mac, with Apple Watch and Wear OS companion apps plus optional remote access through VPN, OctoEverywhere or Obico

Find the local IP address

Open the printer’s network settings and select the active Wi-Fi or Ethernet connection. Look for an IPv4 address similar to 192.168.1.42 or 10.0.0.25.

This address identifies the printer inside the local network. Do not enter the router address, the phone address, a public internet address or a Bambu Cloud URL. Printer Tools must be able to reach the address from the device running the app.

An IP address can change after the router or printer restarts. If a previously working printer becomes unreachable, compare the saved address with the value currently shown on the touchscreen.

Find the printer serial number

The serial number identifies the physical printer and helps Printer Tools choose the correct Bambu model family and camera behavior. Copy the entire value exactly, without adding spaces or shortening a prefix.

Use the value reported by the printer’s device information or network screen. Do not use the serial number of an AMS, build plate, accessory or retail box unless it exactly matches the printer value.

Model detection matters because Bambu camera transports differ. A wrong or incomplete serial can route the connection to the wrong camera method even when MQTT telemetry appears.

Find the LAN Access Code

The LAN Access Code is the local credential exposed by the printer for authorized LAN clients. It is normally shown in the printer’s network or LAN settings. Copy it with the same capitalization and punctuation displayed by the printer.

This code is not your Bambu account password. Printer Tools does not need your cloud password for a local printer connection.

Treat the LAN Access Code as a secret. Do not post screenshots that show it, paste it into a public issue or publish a complete camera URL containing it.

Enter the values in Printer Tools

Put the phone, tablet or computer on a network that can reach the printer.
Add a Bambu Lab printer in Printer Tools.
Enter the current IPv4 address.
Enter the full printer serial number.
Enter the LAN Access Code.
Save and wait for the local connection.

Confirm telemetry before diagnosing the camera. If temperatures and status update but Live View does not, check Settings > Network > LAN Only Liveview on the printer.

Avoid auto-fill and copy errors

Password managers can replace the code, add a trailing space or fill an unrelated login. Paste into the intended field and review the beginning and end of each value. When possible, type a short code manually rather than sending it through chat.

Do not include quotation marks around values. If you copied from a formatted document, clear invisible whitespace by deleting the last character and retyping it.

Keep the address stable

Create a DHCP reservation in the router for the printer once the connection works. A reservation lets the router give the same local address to the printer after restarts without configuring an unsupported static network value on the printer itself.

If Printer Tools still cannot find the printer on the network, follow how to fix local network discovery problems in Printer Tools.

Frequently asked questions

Can I use the printer hostname instead of its IP address?

Use the IP address shown by the printer unless the setup screen explicitly supports and resolves the hostname on your network.

Is the LAN Access Code my Bambu password?

No. It is a separate local credential generated and displayed by the printer.

Why did a working connection stop after a router restart?

The printer may have received a different IP address. Compare the current touchscreen value and add a DHCP reservation.

Should I send all three values to support?

No. Share the model and a redacted address if needed, but never send the LAN Access Code in plain text.
