3. Setup Instructions

Follow these steps to install your LASER TREE LT-80W-F45 laser module on a compatible CNC machine (e.g., 3018/3018 Pro).

1. Disconnect Power: Ensure the CNC machine is completely powered off and unplugged from the power source.
2. Mount the Laser Module: Loosen the screw on the side of the CNC machine's bracket. Carefully insert the LT-80W-F45 laser module into the bracket. The cylindrical housing design is specifically made for easy installation. Secure the module by tightening the screws.
3. Connect Cables: Connect the 3-pin input cable (VCC, GND, PWM) from the laser module to the corresponding ports on your CNC control board. Ensure correct polarity.
4. Install Protective Cover: Always install the laser protective cover back onto the module after mounting.
5. Connect Air Assist: Attach the provided air pipe to the air assist nozzle on the laser module. Connect the other end to an external air pump (not included) if you plan to use the air assist feature.

4. Operating Instructions

The LASER TREE LT-80W-F45 module is designed for both engraving and cutting various materials.

4.1 Focusing

This module features a built-in FAC (Fast Axis Collimation) lens, creating a double ultra-fine compressed spot (0.08*0.08mm) for precise work. It is generally focus-setting free for common applications, simplifying operation.

4.2 Material Compatibility & Performance

The 10W optical power output allows for processing a wide range of materials:

• Cutting: Wood, MDF board, plywood, pinewood, black acrylic, paper.
• Engraving: Wood, MDF board, leather, bamboo, black acrylic, stainless steel, rock slabs, fabric, tile.

Example Cutting Parameters (approximate, may vary by material and machine):

• 8mm Plywood: Cut in one pass at 1.5mm/s (with 45mm focus length).
• 3mm MDF: Cut in one pass at 240mm/min.
• 8mm Acrylic: Cut in one pass at 40mm/min.
• 20mm Pinewood: Cut in 6 passes at 100mm/min (with air assist).

4.3 Air Assist Benefits

Utilizing the air assist feature significantly improves cutting and engraving quality:

• Cleaner Edges: Reduces charring and discoloration, resulting in sharper cuts.
• Reduced Smudging: Prevents smoke and debris from settling on the material, keeping the work area cleaner.
• Enhanced Cutting Efficiency: Helps clear away molten material, allowing the laser to penetrate deeper and faster.

5. Maintenance

Proper maintenance ensures optimal performance and longevity of your laser module.

• Protective Window Glass: The laser module's protective window glass must be kept clean and free of fingerprints or debris. Contamination can significantly affect cutting ability and power output. Clean gently with a soft, lint-free cloth and appropriate lens cleaner if necessary.
• Fan Cleaning: Periodically inspect and clean the cooling fan to ensure proper airflow and prevent overheating. Use compressed air to remove dust and debris.
• General Cleaning: Keep the exterior of the laser module clean. Avoid using harsh chemicals that could damage the housing.

6. Troubleshooting

If you encounter issues with your LASER TREE LT-80W-F45 laser module, consider the following:

• No Laser Output: Check all cable connections (power, GND, PWM) to ensure they are secure and correctly oriented. Verify that the CNC machine's control board is supplying the correct voltage (24V) and that the PWM signal is active.
• Weak Engraving/Cutting: Ensure the protective window glass is clean. Check the focus of the laser. Verify that the laser power settings in your software are correct and that the material is suitable for the chosen parameters.
• Poor Cut Quality (Smudging/Charring): Ensure air assist is properly connected and functioning. Adjust cutting speed and power settings.
• Overheating: Ensure the cooling fan is operating correctly and is free from obstructions.
