How to Control the LED Light on Nano Duo

Proper control of the LED light on the Nano Duo laser engraver is important for improving visibility, ensuring accurate camera alignment, and enhancing the overall engraving experience. The LED lighting helps illuminate the working area, making it easier to position materials and monitor the engraving process.

The Nano Duo system provides multiple methods to control the LED light depending on the software you are using. Below are the detailed instructions for each supported platform.

1. LightBurn

After successfully connecting Nano Duo to LightBurn, you can control the LED light through the console by sending G-code commands.

Open the console input box and enter the following commands, then press Enter to execute:

$nano/led=off 【Turn off LED】
$nano/led=on 【Turn on LED】

These commands allow direct control over the LED light. Turning off the LED can be useful when working with reflective materials or when reducing ambient interference during engraving. Turning it on helps improve visibility when positioning materials or previewing the work area.

Make sure the device is properly connected before sending commands to avoid communication errors.

2. LaserGRBL

LaserGRBL also supports LED light control using the same command-based method.

After successfully connecting Nano Duo, open the console input box and enter the following commands:

$nano/led=off 【Turn off LED】
$nano/led=on 【Turn on LED】

Press Enter after inputting each command to send it to the device.

This method is particularly useful for users who prefer a lightweight control interface or who are working in a GRBL-based workflow. The LED can be toggled at any time during setup or operation, allowing flexible adjustment based on lighting conditions.

3. LaserBurn PC

In LaserBurn PC software, LED control is integrated into the control interface, allowing for more intuitive operation without manually entering commands.

On the control page, locate and click the Engraving section. You will find an LED Light button that allows you to directly turn the LED light on or off.

This provides a convenient way to control lighting during setup or engraving without needing to use console commands.

Additionally, you can access advanced control options through the top menu. Click the menu button to open the command input window. In this window, you can enter the following commands and click Send to execute:

$nano/led=off 【Turn off LED】
$nano/led=on 【Turn on LED】

This method combines both manual command input and graphical control, giving users more flexibility depending on their workflow preferences.

Conclusion

The Nano Duo LED light can be controlled through multiple software platforms, including LightBurn, LaserGRBL, and LaserBurn PC. Whether using direct console commands or built-in interface controls, users can easily switch the LED light on or off based on their needs.

Proper LED control improves visibility, enhances camera alignment, and contributes to more accurate engraving results. By understanding and using these control methods, users can optimize their working environment and achieve better engraving performance.
