2. Sicherheitshinweise

Your OMTech AF 60W CO2 Laser Engraver is a Class 2 laser product. Adherence to safety guidelines is paramount to prevent injury and ensure proper machine function.

• Augenschutz: Always wear appropriate laser safety glasses when operating the machine, even with the flame-resistant observation window.
• Belüftung: Ensure the efficient exhaust system is properly connected and functioning to direct hazardous debris and fumes away from the engraving surface and into your ventilation system. Operating without adequate ventilation can be harmful.
• Brandschutz: Keep a fire extinguisher nearby. Never leave the machine unattended during operation, especially when cutting flammable materials.
• Not-Halt: Machen Sie sich mit dem Standort und der Bedienung des Not-Aus-Knopfes vertraut.
• Materialverträglichkeit: Only engrave or cut materials approved for CO2 lasers. Avoid materials that produce toxic fumes or are highly reflective. Refer to the material compatibility table in the Operating section.

3. Einrichtung

Proper setup is crucial for optimal performance and safety. Follow these steps to prepare your laser engraver for use:

1. Auspacken und Aufstellen: Carefully unpack the machine. Place it on a stable, level surface in a well-ventilated area, away from flammable materials.
2. Connect Exhaust System: Attach the provided exhaust hose to the machine's exhaust port and route it to an external vent or a dedicated fume extractor.
3. Luftunterstützung anschließen: Connect the air assist pump to the designated port on the machine. Air assist helps to clear debris and reduce scorching during operation.
4. Wasserkühler anschließen: Connect the water chiller (or pump) to the laser tube's inlet and outlet ports. Ensure the chiller is filled with distilled water and operating correctly to maintain the laser tube's temperature.
5. Stromanschluss: Schließen Sie die Maschine an eine geerdete Steckdose an.
6. Softwareinstallation: Install the necessary software (RDWorks, LightBurn, CorelDRAW, AutoCAD) on your computer and connect it to the laser engraver via USB or Ethernet.
7. Initial Alignment & Focus: While machines are often pre-aligned, it is recommended to verify mirror alignment and focal length according to the detailed instructions in the full user manual. The autofocus function will assist with setting the correct focal distance.

4.3 Setting Parameters and 4-Way Pass-Through

• Adjust laser power and engraving/cutting speed in your software (RDWorks, LightBurn, etc.) based on the material and desired outcome. The maximum engraving speed is 600 mm/s.
• For oversized projects, utilize the 4-way pass-through doors. This allows you to feed longer or wider materials through the machine, expanding your working area beyond the 28"x20" bed.

5. Wartung

Regular maintenance ensures the longevity and consistent performance of your laser engraver.

• Reinigung des Arbeitsbereichs: Regularly clean the honeycomb and blade workbeds to remove debris and residue from cutting and engraving. This prevents buildup that can affect material placement and laser performance.
• Optikreinigung: Periodically clean the laser lens and mirrors with appropriate optical cleaning solutions and wipes to maintain laser beam quality and power.
• Laser Tube Maintenance: Monitor the laser tube's performance. The high-performance 60W DC tube runs strong for up to 1,000 hours, and up to 12,000 hours when used efficiently at lower settings. Replacement is straightforward if needed.
• Wartung des Wasserkühlers: Ensure the water chiller is clean and filled with distilled water. Regularly check for proper water flow and temperature.
• Abgasanlagenprüfung: Inspect the exhaust fan and ducting for blockages or leaks to ensure efficient fume extraction.

6. Fehlerbehebung

If you encounter issues with your OMTech laser engraver, consider the following common troubleshooting steps:

• Mangelhafte Schnitt-/Gravurqualität: Check laser power and speed settings for the specific material. Verify lens and mirror cleanliness and alignment. Ensure the material is flat and properly focused.
• Laser feuert nicht: Confirm all safety interlocks (lid closed, water flow sensor) are engaged. Check the laser power supply and tube connections.
• Maschine reagiert nicht: Verify power connections and software communication. Restart the machine and computer.
• Übermäßiger Rauch/Dämpfe: Inspect the exhaust system for blockages or fan malfunction. Ensure proper ventilation is established.
