5.3 Gravat i tall

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):

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 Sistema de control automàtic

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. Manteniment

Regular maintenance ensures the longevity and optimal performance of your NEJE 5 laser engraver.

• Neteja de la lent: Periodically clean the laser module's protection lens components to maintain laser beam quality. Refer to NEJE.WIKI for detailed instructions.
• Neteja general: Keep the machine free from dust and debris. Use a soft, dry cloth to wipe down the frame and moving parts.
• Lubricació: Occasionally lubricate the linear rails and lead screws as recommended in the detailed user manual to ensure smooth movement.
• Actualitzacions de firmware: Keep your NEJE software and firmware updated for the latest features and performance improvements.

7. Solució De Problemes

Aquí teniu alguns problemes comuns i possibles solucions:

• La màquina no respon: Check power connections, USB cable connection, and ensure the software is correctly connected via Bluetooth or USB.
• Mala qualitat de gravat/tall: 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.
