      Setting Up GRBL Laser Network Connections

      Overview GRBL Network Connection Setup

      This guide details how to connect a GRBL-based laser machine to a local network (e.g., a home router). While this example uses the Sculpfun iCube, the process applies to most GRBL devices capable of network connectivity. Specific settings may vary between devices, so consult your laser's manual for additional guidance.

      Step 1: Initial USB Connection

      Why USB for Wi-Fi Setup?
      You'll need a USB connection to configure your laser's network settings.

      Instructions:

      1. Connect via USB:
        Use a USB cable to connect your laser to the computer.
      2. Verify Connection in LightBurn:
        • Open the Laser Window and check the device status.
        • If Ready appears, the connection is successful.
        • If Disconnected, ensure the correct serial port is selected or reset the connection.
      3. Access the Console Window:
        • Open the Console window from the LightBurn interface.
        • Use it to configure network settings in subsequent steps.

      Step 2: Retrieve Network Information

      When connected, the laser's network status displays in the Console. Look for a message like:
      [Radio Mode: AP, Sculpfun iCube44285, 192.168.4.1, Not connected]

      Guide-GRBLNetworkConnection-StartupStatus

      Key Terms:

      • Radio Mode:
        Indicates network type. "AP" means Access Point mode, allowing direct Wi-Fi connections. "STA" means Station mode, connecting to an existing network.
      • SSID:
        The network name (Wi-Fi identifier).
      • IP Address:
        The laser's address on the network.
      • Connection Status:
        Indicates whether the laser is connected to a network.

      Step 3: Configure Network Settings

      Depending on your device, you can configure Wi-Fi settings using an app, web interface, or the LightBurn Console.

      Using a Mobile App or Web Interface:

      1. Connect your phone or computer to the laser's Wi-Fi network (AP mode).
      2. Enter the laser's IP address (e.g., 192.168.4.1) in a browser to access the configuration page.
      3. Set the following parameters:
        • Network Type: STA (Station mode)
        • SSID: Your Wi-Fi network name (use 2.4GHz).
        • Password: Your Wi-Fi password.

        Configuration via LightBurn Console:

        1. Open the Console Window.
        2. Enter the following commands:
          • $50=STA (Set to Station mode).

          • $53=YourNetworkName (Set the SSID).
            Guide-GRBLNetworkConnection-SetSSID
          • $54=YourPassword (Set the password).

            Guide-GRBLNetworkConnection-Connected
        3. Restart your laser to apply changes.

        Step 4: Connect to LightBurn Over the Network

        1. Open the Laser Window in LightBurn.
        2. Click Devices, then Create Manually.
        3. Choose GRBL as the device type and select Ethernet/TCP for the connection.
        4. Enter the laser's IP address and configure the work area size.
        5. Save the settings and select the newly created device in LightBurn.

        Troubleshooting Tips

        • Connection Issues:
          • Double-check SSID and password accuracy.
          • Ensure your computer and laser are on the same network.
          • Use a 2.4GHz network if 5GHz causes issues.
        • Stuttering or Job Failures:
          • Enable Synchronous Transfer Mode in LightBurn.
