Connecting to Your Printer

Connecting to Your Printer

This guide will help you connect your Ryzer LED controller to your Bambu Lab 3D printer so the LEDs can respond to print status.

How It Works

Ryzer connects directly to your printer over your local network to receive status updates:

  • Print progress and state
  • Temperature readings
  • Error conditions
  • Layer information

The LEDs respond automatically based on what your printer is doing.

Before You Begin

Make sure you have:

  • ✅ Ryzer connected to your WiFi network (First Time Setup)
  • ✅ Bambu Lab printer connected to the same WiFi network
  • ✅ Access to your printer’s touchscreen
  • ✅ Ryzer web interface open at http://ryzer.local
Ryzer and your printer MUST be on the same network!

Step 1: Find Your Printer Information

You need to gather three pieces of information from your Bambu Lab printer.

1. Printer IP Address

How to find it:

  1. On your printer’s touchscreen, navigate to:

    • Settings (gear icon)
    • Network or WiFi
    • Look for IP Address
  2. Write down the IP address:

    • Format: 10.0.0.252 (example)
    • Usually starts with 192.168.x.x or 10.0.x.x

2. Access Code (LAN Access Password)

What is it? The Access Code is your printer’s local network password. It’s required for any device to connect to your printer.

How to find it:

  1. On your printer’s touchscreen:
    • Settings (gear icon)
    • Network or WiFi
    • Access Code or LAN Access

Access Code location on printer screen

  1. Write down the 8-character code:
    • Format: bc59c3d1 (example)
    • Contains numbers and lowercase letters
    • Case-sensitive!
You can change the Access Code if needed. Just remember to update Ryzer with the new code!

3. Device Serial Number

What is it? Your printer’s unique identifier used for the connection.

How to find it:

  1. On your printer’s touchscreen:

    • Settings (gear icon)
    • Device or About
    • Serial Number or SN
  2. Write down the serial number:

    • Format: 00M09C431202374 (example)
    • Starts with 00M or 01M or 01P
    • 15 characters total

Quick Reference Table

Fill this in as you gather information:

SettingYour ValueExample
Printer IP_________________10.0.0.252
Access Code_________________bc59c3d1
Serial Number_________________00M09C431202374
Client ID(leave default)bambu-led-controller

Step 2: Configure Ryzer Connection

Now let’s enter this information into Ryzer:

  1. Open Ryzer web interface:

    • Navigate to http://ryzer.local or your Ryzer IP address
    • Go to the Connection page
  2. Enter printer information:

    Server (IP Address):

    • Enter your printer’s IP address
    • Example: 10.0.0.252
    • No http:// or other prefix needed

    Password (Access Code):

    • Enter the 8-character access code
    • Case-sensitive: use lowercase only
    • Example: bc59c3d1

    Device ID (Serial Number):

    • Enter your printer’s serial number
    • Usually starts with 00M, 01M, or 01P
    • Example: 00M09C431202374

    Client ID:

    • Leave as default: bambu-led-controller
    • Or customize if you prefer (letters, numbers, hyphens only)

Step 3: Test the Connection

Before saving, let’s verify the connection works:

Make sure your Bambu printer is powered on before testing the connection.
  1. Click “Test Connection” button:

    • Ryzer will attempt to connect to your printer
    • This takes 5-10 seconds
  2. Watch for result:

    • Success: “Connection successful!” message
    • Failed: Error message with details

If Connection Succeeds

Great! You’ll see:

  • “Successfully connected to printer”
  • Green checkmark or success indicator

Proceed to Step 4 to save your settings.

If Connection Fails

Common error messages and solutions:

“Connection timeout”

Cause: Can’t reach printer at that IP address Solutions:

  • Double-check printer IP address
  • Ensure printer is powered on
  • Verify printer is connected to WiFi (check printer screen)
  • Ping printer: ping 10.0.0.252 (use your IP)
  • Make sure Ryzer and printer are on same network

“Authentication failed”

Cause: Wrong access code/password Solutions:

  • Verify access code on printer (Settings → Network)
  • Check for typos (case-sensitive!)
  • Try copying/pasting the code
  • Ensure you’re using the LAN access code (not Bambu Cloud password)

“Connection refused”

Cause: Printer not accepting connections Solutions:

  • Restart printer (power cycle)
  • Check printer firmware is up to date
  • Verify LAN mode is enabled on printer
  • Try different client ID

Step 4: Save Configuration

Once the test succeeds:

  1. Click “Save Configuration” button

  2. Wait for confirmation:

    • “Configuration saved successfully”
    • Settings are stored in Ryzer’s filesystem
  3. Ryzer will now connect automatically:

    • On every boot
    • After network reconnection
    • When returning from sleep mode
Your settings are saved to Ryzer’s internal storage. Even after power loss, your configuration is preserved!

Step 5: Verify Connection Status

Let’s confirm Ryzer is receiving data from your printer:

Check Connection Indicator

On the Ryzer web interface Connection page:

  • Green indicator: Connected and receiving data
  • Red indicator: Not connected
  • Yellow indicator: Connecting…

Start a Print (Optional)

Want to see it in action?

  1. Start any print on your Bambu Lab printer

  2. Watch for LED response:

    • LEDs will change based on print status
    • Indicates Ryzer is receiving print updates
  3. Check Ryzer interface:

    • Connection page shows current status
    • Look for “Connected” indicator

Troubleshooting Connection

Connection Works But No LED Response

To verify it’s working:

  • Check that Test Connection succeeds
  • Verify connection indicator is green

Connection Drops After a While

Possible causes:

  • Printer went to sleep mode
  • Router dropping idle connections
  • Weak WiFi signal

Solutions:

  • Check WiFi signal strength of both devices
  • Move devices closer to router
  • Update Ryzer firmware (improved reconnection logic)

Can’t Connect to Printer After it Moves

If you moved your printer to a different network:

  1. Find printer’s new IP address
  2. Update Ryzer configuration with new IP
  3. Test and save

If printer IP changed on same network (DHCP):

  1. Check printer for new IP address
  2. Update Ryzer configuration
  3. Consider setting static IP on printer (router settings)

Multiple Printers

Want to connect to multiple Bambu Lab printers?

Currently, Ryzer can only connect to ONE printer at a time. To switch printers:

  1. Go to Connection page
  2. Enter new printer’s information
  3. Test and save

Future firmware may support multiple printers with LED strip zones.

Supported Bambu Lab Printers

Ryzer has been tested with:

  • X1 Series (X1, X1 Carbon)
  • P1 Series (P1P, P1S)
