How to Switch Between Red and Blue Lasers on Nano Duo Using the Screen

Nano DUO is equipped with a built-in screen that allows for basic operations. The steps to switch between red and blue laser engraving are as follows:

1. Tap File scanning and select the desired engraving file.
Note: Make sure the SD card is inserted into the slot.

2. In Light Source, tap the dropdown menu and select:
450 nm [Blue Laser] or 1064nm [Infrared Laser]

Note: Only files generated by LightBurn and LaserGRBL support red and blue laser switching. Since LaserBurn integrates commands that enable simultaneous dual-laser engraving into the *.gc file, the light source cannot be changed through the screen.
