2. Safety Information

Always prioritize safety when operating laser equipment. Failure to follow safety guidelines can result in serious injury.

• Wear Protective Eyewear: Always wear appropriate laser safety goggles during operation, even with integrated eye protection features, to prevent eye damage.
• Avoid Direct Exposure: Never look directly into the laser beam or at reflections.
• Keep Hands Clear: Do not touch the laser outlet with your hands during operation.
• Supervise Children: This product is not suitable for children under 14 years of age. Children over 14 years of age require adult supervision.
• Ventilation: Ensure adequate ventilation in the work area to dissipate smoke and fumes produced during engraving or cutting.
• Fire Safety: Be aware of flammable materials. Keep a fire extinguisher nearby.

4. Setup

4.1. Module Installation

Attach the NEJE N40630 module to your engraving machine's X-axis carriage using the provided sliding slot and screws. Ensure it is securely fastened to prevent movement during operation.

4.2. Electrical Connections

Connect the laser module to the interface adapter board. The adapter board typically has inputs for power (DC 12V, 2A/3A/4A), GND, Signal, and TTL. Ensure correct polarity and pin assignments according to your machine's control board (e.g., GRBL).

4.3. Focusing the Laser

The N40630 module features an adjustable lens for focusing. Rotate the focus cap to achieve the smallest possible laser spot on your material. A smaller focus spot generally results in better engraving and cutting accuracy. The optimal focusing range is typically 30-50mm from the engraving object. For cutting, a slightly larger focus might be preferred to achieve a cleaner cut.

4.4. Air Assist (Optional)

For enhanced cutting performance and to prevent smoke damage to the laser lens, consider installing an air assist system. This directs a stream of air at the cutting point, clearing debris and improving cut quality.

5. Operating Instructions

5.1. Software Compatibility

The NEJE N40630 module is compatible with various control software, including NEJE's proprietary software, LightBurn, and LaserGRBL. Ensure your software is updated to the latest version for optimal performance and features.

5.2. Engraving and Cutting Process

Prepare your design in the chosen software. Place the material on the engraving bed, ensuring it is flat and secure. Use the software's preview function to confirm the laser path and position. Adjust laser power and speed settings according to the material and desired effect. Initiate the engraving or cutting process.

6. Maintenance

• Lens Cleaning: Regularly clean the laser lens with a cotton swab and appropriate lens cleaning solution to maintain optimal laser performance.
• Fan Maintenance: Ensure the cooling fan is free from dust and debris to prevent overheating and maintain efficient operation.
• Module Inspection: Periodically inspect the module for any loose connections or physical damage.

7. Troubleshooting

• Laser Not Firing: Check all electrical connections, ensure the power supply is adequate, and verify software settings for laser output.
• Weak Laser Output: Re-focus the laser module. Clean the laser lens. Check for any obstructions in the laser path.
• Connection Issues: Ensure the USB cable is securely connected to both the machine and the computer. Try a different USB port or cable. Reinstall drivers if necessary.
• Overheating: Ensure the cooling fan is operating correctly and is not obstructed. Reduce laser power or increase cooling time between operations if persistent.
