2. Safety Information

Operating a laser engraver requires strict adherence to safety guidelines to prevent injury. The Twotrees TTS-20 Pro is a Class 4 laser product, meaning its laser radiation is hazardous to the eye and skin. Always take necessary precautions.

• Eye Protection: Always wear appropriate laser safety goggles that block the specific wavelength of the laser (typically 450nm for diode lasers) when the machine is in operation. Never look directly into the laser beam or at its reflection.
• Skin Protection: Avoid direct exposure of skin to the laser beam.
• Ventilation: Ensure adequate ventilation in your workspace to dissipate fumes and smoke produced during engraving and cutting, especially when working with materials like wood, acrylic, or leather.
• Fire Safety: Keep a fire extinguisher nearby. Never leave the machine unattended during operation, as some materials can ignite.
• Children and Pets: Keep children and pets away from the operating area.
• Material Safety: Only engrave or cut materials that are safe for laser processing. Avoid materials that produce toxic fumes or can explode when exposed to laser energy.
• Emergency Stop: Familiarize yourself with the location and operation of the emergency stop button.

4. Operating Instructions

The Twotrees TTS-20 Pro offers powerful engraving and cutting capabilities across a variety of materials. Here are instructions and tips for optimal operation:

4.1 Material Compatibility and Tips

This engraver can process over 100 materials, including wood, leather, aluminum oxide, and glass.

• Wood Cutting: For optimal wood cutting performance, it is highly recommended to use an air assist system (not included). This helps to clear debris and prevent charring, resulting in cleaner cuts.
• Transparent Materials (Acrylic/Glass): When engraving transparent materials, such as clear acrylic or glass, apply black paint to the surface where you intend to engrave. The black paint absorbs the laser energy, allowing for effective engraving. Transparent colors will not react effectively with the laser head without this preparation.
• Metal Engraving: The 20W laser is capable of colorful engraving on metal surfaces, expanding creative possibilities.

4.2 Precision and Speed

The TTS-20 Pro offers exceptional precision and speed for detailed work.

• Ultra-Fine Spot: Advanced compressed spot technology ensures crisp, clean engravings.
• High Speed: Achieve speeds up to 500mm/s for efficient project completion.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Twotrees TTS-20 Pro laser engraver.

• Cleaning the Lens: Periodically clean the laser lens with a specialized lens cleaning solution and a lint-free cloth to maintain laser power and precision.
• Cleaning the Machine: Keep the machine free of dust and debris. Use compressed air to clean hard-to-reach areas.
• Lubrication: Apply a small amount of lubricant to the guide rails and lead screws as recommended in the detailed manual to ensure smooth movement of the laser head.
• Belt Tension: Check the tension of the drive belts regularly. Belts that are too loose or too tight can affect engraving accuracy. Adjust as needed.
• Honeycomb Panel: Clean the honeycomb work panel frequently to remove accumulated residue, which can affect cutting performance and cause back reflections.

6. Troubleshooting

This section addresses common issues you might encounter with your Twotrees TTS-20 Pro laser engraver.

• Issue: Laser not engraving/cutting transparent materials.
  Solution: As mentioned in the operating instructions, transparent materials do not absorb laser light effectively. Apply a thin layer of black paint or use a dark, opaque masking tape on the surface before engraving. The laser will engrave the paint/tape, transferring the design to the material underneath.
• Issue: Engravings are blurry or inconsistent.
  Solution: Check the focus of the laser. Ensure the material is flat and properly secured. Verify that the machine's frame is rigid and not wobbling. Inspect the belts for proper tension and ensure the guide rails are clean and lubricated.
• Issue: Machine not connecting to software.
  Solution: Ensure all cables are securely connected. Verify that the correct drivers are installed on your computer. Restart both the engraver and your computer. Check software settings to ensure the correct COM port or connection type is selected.
• Issue: Excessive smoke or charring during operation.
  Solution: This can indicate that the laser power is too high or the speed is too low for the material. Adjust settings in your software. Ensure proper ventilation and consider using an air assist system, especially for wood cutting.
