2. Safety Instructions

WARNING: Laser radiation can cause eye damage and skin burns. Always wear appropriate laser safety goggles when operating the machine. Never look directly into the laser beam.

• Eye Protection: Always wear certified laser safety goggles (OD4+ or higher) that block the laser wavelength (typically 450nm for blue lasers) during operation.
• Ventilation: Operate the machine in a well-ventilated area or use an exhaust system to remove smoke and fumes produced during engraving/cutting. Some materials can produce toxic fumes.
• Fire Safety: Keep a fire extinguisher nearby. Do not leave the machine unattended during operation, especially when cutting flammable materials. Ensure the work surface is non-flammable.
• Material Safety: Only engrave or cut materials that are safe for laser processing. Avoid PVC, vinyl, and other chlorine-containing plastics as they produce corrosive and toxic fumes.
• Children and Pets: Keep children and pets away from the operating area.
• Electrical Safety: Ensure the power supply is stable and correctly connected. Do not operate with wet hands or in damp conditions.
• Emergency Stop: Familiarize yourself with the location of the emergency stop button (if present) or how to quickly disconnect power.

5. Operating Instructions

This section outlines the basic steps for operating your laser engraving and cutting machine.

5.1. Preparing Your Material

• Place the material to be engraved or cut on the work surface. Ensure it is flat and securely positioned.
• Verify the material type and thickness to select appropriate laser settings.

5.2. Focusing the Laser

The A40640 module typically features a fixed focus. For optimal results, ensure the distance between the laser module and the material surface is correct. Refer to the module's specific instructions for the recommended focal length, often indicated by a small spacer or a fixed height.

5.3. Software Operation

• Launch your chosen engraving software (e.g., LightBurn, NEJE software).
• Import your design (image, vector file).
• Adjust the size and position of your design on the virtual workspace to match your material.
• Select the appropriate laser settings (power, speed, number of passes) based on your material and desired effect. Refer to material test guides for starting parameters.
• Preview the job to ensure correct placement and settings.

5.4. Starting the Job

• Ensure all safety precautions are in place (goggles on, ventilation active).
• Power on the machine.
• Click 'Start' or 'Send' in your software to begin the engraving/cutting process.
• Monitor the process closely for any issues.

6. Maintenance

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

• Laser Lens Cleaning: Periodically clean the laser lens with a lint-free cloth and lens cleaning solution (e.g., isopropyl alcohol) to remove dust and debris that can affect laser performance.
• Machine Cleaning: Keep the machine free of dust and material residue. Use compressed air to clean hard-to-reach areas.
• Rail and Belt Inspection: Check the linear rails and belts for smooth movement and proper tension. Lubricate rails if necessary.
• Cable Connections: Ensure all electrical connections are secure and free from damage.
• Laser Module Lifespan: Laser diodes have a finite lifespan. Proper use and maintenance can extend it. Avoid operating at maximum power for extended periods if not necessary.
