Quick Answer

To set the Nano Duo engraving mode:

• In LaserGRBL, turn on the Nano Duo and click to start the engraving mode, then select the desired mode:
  • Red laser mode
  • Blue laser mode
  • Conveyor belt mode
  • Rotary chuck mode
  • Cross-slide mode
• In LightBurn:
  • IR 1064 nm = red laser engraving mode
  • BL 450nm = blue laser engraving mode
  • Single-Axis Mode = conveyor belt/rotary chuck mode
  • Dual-Axis Mode = cross-slide mode

Using the correct mode ensures proper laser operation and accessory compatibility.

Why This Process Matters

The Nano Duo supports multiple engraving configurations and accessories. Selecting the wrong engraving mode can lead to:

• Incorrect laser operation
• Accessories not responding properly
• Framing errors
• Motion issues during engraving
• Poor engraving results

The engraving mode determines how the machine communicates with the laser module and connected accessories. Proper configuration is especially important when switching between:

• Infrared and blue lasers
• Rotary engraving
• Conveyor workflows
• Cross-slide systems

Following the official mode selection process helps maintain engraving accuracy and workflow stability.

Before You Start

Before changing engraving modes, ensure:

• The Nano Duo is powered on
• The machine is connected to your software
• You are using supported software versions
• All accessories are properly installed
• The work area is clear and safe

If additional setup information is required, follow official machine specifications or instructions.

Requirements

You may need:

• LaserGRBL
• LightBurn
• Nano Duo
• USB connection or supported connection method
• Optional accessories:
  • Conveyor belt
  • Rotary chuck
  • Cross-slide accessory

Official software and documentation are available through LONGER Official Website.

Precautions

Before switching engraving modes, keep these safety tips in mind:

• Always verify the selected laser mode before starting engraving
• Ensure accessories are firmly connected
• Avoid touching moving parts during operation
• Wear appropriate laser safety protection
• Confirm the correct material settings before engraving
