5. Opsætning
The LASER TREE Laser Engraver Module is designed for easy integration into compatible laser engraving and cutting machines. Follow these general steps for setup:
- Montering: Securely attach the laser module to your engraving machine's gantry or designated mounting bracket. Ensure it is stable and aligned correctly. The module features four M3 tapped holes for mounting.
- Ledningsføring: Connect the provided 3-pin cable to the XH2.54-3P socket on the laser module. Connect the other end to your machine's control board, ensuring correct polarity for DC 12V, Ground (GND), and 5V PWM signal. Refer to your machine's manual for specific wiring instructions.
- Strømforsyning: Connect your machine to a stable DC 12V power supply capable of providing at least 1.6A (1.4-1.8A recommended).
- Softwarekonfiguration: Configure your engraving software (e.g., LightBurn, GRBL) to recognize and control the laser module. Set appropriate power and speed settings for your desired material and effect.
- Fokusjustering: Before starting any job, adjust the laser's focal length. The adjustable focus range is 20mm to 50mm. Rotate the lens barrel to achieve the smallest, sharpest laser dot on your material for optimal engraving or cutting.

6. Betjeningsvejledning
Once the laser module is set up and configured, you can begin your engraving or cutting projects. Always ensure safety precautions are followed.
- Materiale placering: Place your material securely on the engraving bed. Ensure it is flat and properly positioned according to your software's workspace.
- Focus Verification: Double-check the laser focus for the specific material thickness. A precise focus is critical for clean cuts and sharp engravings.
- Test Engraving/Cutting: It is recommended to perform small test engravings or cuts on scrap material to determine optimal power and speed settings before starting your main project.
- Start drift: Initiate the engraving or cutting process through your machine's control software. Monitor the process closely.
- Ventilation: Maintain continuous and adequate ventilation throughout the operation to remove smoke and debris.
- Færdiggørelse: Once the job is complete, allow the laser module to cool down before handling. Remove the finished material and clean the work area.

8. Fejlfinding
If you encounter issues with your laser module, refer to the following common problems and solutions:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Laseren affyrer ikke | No power, incorrect wiring, software issue, faulty module | Check power supply (12V DC), verify wiring connections (GND, 12V, PWM), ensure software is sending PWM signal, contact support if module is suspected faulty. |
| Weak engraving/cutting | Incorrect focus, low power setting, material incompatibility, dirty lens | Adjust focus for a sharp dot, increase laser power in software, ensure material is compatible, clean the laser lens. |
| Inkonsistente resultater | Unstable mounting, material movement, power fluctuations | Ensure module is securely mounted, material is clamped firmly, use a stable power source. |
| Overophedning | Blocked fan/heatsink, prolonged high power use | Clean fan and heatsink, ensure proper ventilation, allow module to cool between long operations. |
