3. Specifications

Below are the general specifications for the LASER TREE laser modules. Specific models may vary slightly.

4. Safety Information

WARNING: LASER RADIATION. AVOID DIRECT EYE EXPOSURE TO THE BEAM.

• Always wear appropriate laser safety goggles when operating the laser module.
• Ensure the work area is well-ventilated to dissipate fumes from cutting/engraving.
• Never leave the laser module unattended during operation.
• Keep children and pets away from the work area.
• Do not operate the laser module near flammable materials.
• Ensure proper grounding of all equipment.
• The laser view window is made of anti-blue light optical glass to protect your eyes from blue light.

5. Installation

The LASER TREE laser modules are designed for easy integration with various DIY laser engraving machines.

5.1 Unpacking and Components

Verify all components are present based on your specific model (EU or US plug version).

5.2 Mounting the Laser Module

The module features an integrated dovetail guide rail design (115mm length) for smooth movement and easy height/focus adjustment. A sliding plate with multiple holes is provided for compatibility with various laser engraver machines.

5.3 Wiring and Connections

The laser module uses a 2EDG3.81 pluggable connector for its input port (VCC (DC24V), GND, TTL/PWM (0-5kHz)). Refer to the compatibility table for specific wiring solutions based on your machine's voltage and PIN configuration.

6. Operation

6.1 Power On and Indicators

Once connected, the module features a working status indicator:

• Power indicator: Red when power supply is connected.
• Signal indicator: Green when signal is received.

6.2 Red Cross Line Locating

Use the red cross line for precise material positioning before starting your engraving or cutting job.

6.3 Focusing

The module is equipped with a fixed focus lever for easy adjustment of the focus distance according to different engraving and cutting requirements.

6.4 Air Assist

The built-in air assist airway helps achieve clean-cut edges and improves overall cutting performance. An air pump suggestion is: air pressure and capacity: ≥0.027kPa, 27L/min. Air tube: outer diameter 8mm and inner diameter 5mm.

6.5 Cutting and Engraving Performance Examples

The modules are capable of cutting and engraving various materials including steel, wood, stone, black acrylic, and leather.

7. Maintenance

• Protection Window: The copper core protection lens is easy to clean and replace when contaminated or dusty. Regularly check and clean the lens to maintain optimal laser performance.
• Cooling System: The dual-fan cooling system ensures excellent heat dissipation. Keep the fans free from dust and debris to maintain efficient cooling and reduce noise.
• General Cleaning: Keep the laser module clean from dust and material residue. Use a soft, dry cloth for cleaning.

8. Troubleshooting

• Laser not firing or weak output:
  - Check power connections and ensure the power indicator is red.
  - Verify the signal indicator is green, indicating a signal is received.
  - Ensure the focus is correctly set for the material thickness.
  - Clean the protection lens if it is contaminated.
• Overheating Alarm:
  - If the working temperature exceeds 55°C, an alarm will sound. Stop operation immediately.
  - Check for obstructions in the cooling fans or vents.
  - Allow the module to cool down before resuming operation.
• Poor Cut Quality / Engraving:
  - Adjust focus settings according to material thickness.
  - Ensure air assist is properly connected and functioning to clear debris.
  - Verify laser power and speed settings in your software are appropriate for the material.
• Compatibility Issues:
  - If adapting the module to a different machine, ensure the controller card and power supply are compatible with the module's voltage and PIN configuration (e.g., 12V/24V, 2PIN/3PIN). A driver adapter or external power supply may be required.

9. User Tips

• Optimal Cutting: For best cutting results, especially on thicker materials, ensure your air assist system is fully functional. This helps clear smoke and debris, leading to cleaner edges and preventing charring.
• Software Settings: When using LightBurn or similar software, remember to adjust laser offset settings (e.g., Y: -21mm for red cross line locating) for accurate positioning.
• Upgrading for Speed: If you are looking for increased cutting speed, consider upgrading to a higher optical power module (e.g., from 20W to 40W or 60W). Always check compatibility with your existing machine's controller.
• Material Testing: Always perform small test cuts or engravings on scrap material to fine-tune your power and speed settings before starting a larger project.
