5.3 Engraving and Cutting
Prepare your design using your chosen software (LightBurn, LaserGRBL, or NEJE APP). Ensure the material is properly placed and secured within the working area. Adjust laser power and speed settings according to the material and desired effect. Always perform test engravings/cuts on scrap material first.
Cutting Speed Examples (NEJE A40630 Laser Module):
| Laser Module | Cutting Speed |
|---|---|
| NEJE A40630 | |
| plywood 2mm cut : | 160mm/min ,S1000, 1 pass |
| plywood 3mm cut : | 120mm/min ,S1000, 1 pass |
| plywood 4mm cut : | 100mm/min ,S1000, 1 pass |
| plywood 8mm cut : | 120mm/min ,S1000, 3 pass |
| plywood 18mm cut : | 120mm/min ,S1000, 8 pass |
| birch ply 3mm : | 240mm/min ,S1000, 1 pass |
| MDF board 3mm cut : | 120mm/min ,S1000, 2 pass |
| MDF board 5mm cut : | 120mm/min ,S1000, 4 pass |
| MDF board 8mm cut : | 120mm/min ,S1000, 5 pass |
| balck acrylic plate 3mm cut : | 120mm/min ,S1000, 2 pass |
| balck acrylic plate 5mm cut : | 120mm/min ,S1000, 4 pass |
NOTE: The above data needs to add air assist correctly (0.6-1.5MPa) with LaserGRBL or LightBurn. LightBurn: 60mm/min = 1mm/sec, S1000 = 100% Power.

5.4 Automatic Control System
The NEJE 5 incorporates an automatic control system to enhance user experience and safety:
- Automatic Air Assist (M8): Integrates with software commands for automated air assistance during cutting, improving cut quality and reducing charring.
- Automatic Smoke Discharging (M7): Can be configured to activate smoke extraction systems.
- Emergency Door Button (DOOR): Provides an immediate stop function for safety.


6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your NEJE 5 laser engraver.
- Cleaning the Lens: Periodically clean the laser module's protection lens components to maintain laser beam quality. Refer to NEJE.WIKI for detailed instructions.
- General Cleaning: Keep the machine free from dust and debris. Use a soft, dry cloth to wipe down the frame and moving parts.
- Lubrication: Occasionally lubricate the linear rails and lead screws as recommended in the detailed user manual to ensure smooth movement.
- Firmware Updates: Keep your NEJE software and firmware updated for the latest features and performance improvements.

7. Troubleshooting
Here are some common issues and potential solutions:
- Machine not responding: Check power connections, USB cable connection, and ensure the software is correctly connected via Bluetooth or USB.
- Poor engraving/cutting quality: Verify laser focus, adjust power and speed settings for the specific material, ensure the material is flat and secured, and check if air assist is properly connected and functioning for cutting.
- Laser not firing: Ensure the laser module is correctly installed and connected. Check software settings for laser activation.
- Accidental touch stops operation: This is a safety feature (MEMS protection). Ensure the working area is clear and avoid touching the machine during operation.
For more detailed troubleshooting, refer to the comprehensive guides and community forums on NEJE.WIKI.
