Please read this manual thoroughly before operating the machine to ensure proper usage and to prevent damage or injury.

2. Safety Information

Operating a laser engraver involves inherent risks. Adhere to all safety precautions to prevent accidents and ensure personal safety.

• Eye Protection: Always wear certified laser safety goggles when the machine is operating. Never look directly at the laser beam or its reflection.
• Ventilation: Operate the machine in a well-ventilated area or use an appropriate fume extraction system. Laser engraving and cutting can produce smoke, fumes, and potentially harmful particles.
• Fire Hazard: Keep a fire extinguisher nearby. Do not leave the machine unattended during operation, especially when cutting flammable materials. Ensure the work area is clear of combustible materials.
• Material Safety: Only engrave or cut materials approved for laser processing. Avoid materials that produce toxic fumes or catch fire easily (e.g., PVC, certain plastics).
• Children and Pets: Keep children and pets away from the operating machine.
• Emergency Stop: Familiarize yourself with the location and operation of the emergency stop button.
• Power Supply: Use only the provided power adapter and ensure it is connected to a grounded outlet.

5. Operating Instructions

5.1 Powering On and Off

• Power On: Connect the power cable and press the power button on the machine. The touch screen will illuminate.
• Power Off: Press and hold the power button or use the software interface to shut down the machine safely. Disconnect power only after the machine has fully powered down.

5.2 Connectivity Modes

The RAY5 20W supports four connection modes:

• USB Connection: Connect the machine to your computer via the provided USB cable.
• TF Card: Load G-code files directly onto a TF card and insert it into the machine's slot for offline operation.
• WiFi Connection: Connect the machine to your local Wi-Fi network for wireless control via a computer or mobile device.
• APP Control: Use the dedicated mobile application for remote control and monitoring.

5.3 Material Preparation and Focusing

1. Secure Material: Place your material on the work bed and secure it to prevent movement during operation.
2. Focus the Laser: Adjust the laser module's height until the laser spot is at its smallest and most intense point on the material surface. This ensures optimal engraving and cutting quality.

5.4 Starting an Engraving/Cutting Job

1. Design Preparation: Create or load your design in LaserGRBL or LightBurn.
2. Parameter Settings: Adjust engraving/cutting parameters such as laser power, speed, and passes based on the material type and desired outcome. The RAY5 20W offers high precision and speeds up to 10000mm/min.
3. Enable Air Assist: If cutting or engraving materials that produce significant smoke or require cleaner edges, turn on the Air Assist pump. Adjust airflow as needed (10-30L/min).
4. Start Job: Initiate the job from the software or directly from the 3.5-inch touch screen if using a TF card. Monitor the process closely.

6. Maintenance

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

• Clean Laser Lens: Periodically clean the laser lens with a lint-free cloth and isopropyl alcohol to remove dust and debris. A dirty lens can reduce laser power and engraving quality.
• Clean Work Area: Keep the work bed and surrounding area clean from debris and residue.
• Inspect Belts and Rails: Check the tension of the timing belts and ensure the linear rails are clean and free of obstructions. Lubricate rails if necessary according to manufacturer guidelines.
• Air Pump Filter: If your air pump has a filter, clean or replace it as recommended to maintain optimal airflow.
