2. Safety Information

Operating a laser engraver requires strict adherence to safety protocols to prevent injury and damage. Please read and understand all safety warnings before use.

• Eye Protection: Always wear the provided safety glasses or equivalent laser-protective eyewear when the machine is operating. Never look directly at the laser beam.
• Ventilation: Ensure adequate ventilation in your workspace. Laser engraving and cutting can produce fumes and particles that may be harmful if inhaled.
• Fire Hazard: The laser can ignite flammable materials. Do not leave the machine unattended during operation. Keep a fire extinguisher nearby.
• Material Compatibility: Only engrave or cut materials approved for laser processing. Avoid highly reflective materials without proper precautions (see Troubleshooting).
• Emergency Stop: Familiarize yourself with the location and operation of the emergency stop button.
• Children and Pets: Keep children and pets away from the operating area.

6. Maintenance

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

• Clean Lens: Periodically clean the laser lens with a soft, lint-free cloth and lens cleaning solution. Dust and debris can reduce laser efficiency.
• Clean Rails: Keep the guide rails and wheels free of dust and debris to ensure smooth movement of the laser module.
• Check Connections: Regularly inspect all cables and connections for wear or looseness.
• Firmware Updates: Check the manufacturer's website for any available firmware updates to improve performance and add features.

7. Troubleshooting

This section addresses common issues you might encounter.

7.1. Laser Module Degradation on Reflective Materials

Issue: Reduced laser output or module failure after engraving highly reflective materials, such as stainless steel, especially at high power settings.

Cause: When engraving highly reflective surfaces, a portion of the laser beam can reflect back into the laser module's diode, causing damage and premature degradation.

Solutions:

• Reduce Reflection: Before engraving reflective materials, apply a non-reflective coating (e.g., black paint, dry erase marker, or a specialized laser marking spray) to the surface. This absorbs the laser energy and prevents harmful reflections.
• Adjust Power Settings: Avoid using 100% laser power when working with highly reflective materials. Experiment with lower power settings that still achieve the desired engraving effect.
• Consult Material Guidelines: Always refer to recommended settings for specific materials to minimize risks.

7.2. Other Common Issues

• Machine Not Powering On: Check power cable connections and ensure the power adapter is functioning.
• Laser Not Firing: Verify software settings, focus, and ensure the laser module is properly connected.
• Poor Engraving Quality: Check focus, laser power settings, engraving speed, and material type. Ensure the material is flat and securely placed.
• Abnormal Movement: Inspect guide rails for obstructions and ensure belts are properly tensioned.
