7. Manutenzione

  • 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.
  • Sistema di raffreddamento: The dual-fan cooling system ensures excellent heat dissipation. Keep the fans free from dust and debris to maintain efficient cooling and reduce noise.
  • Pulizia generale: Keep the laser module clean from dust and material residue. Use a soft, dry cloth for cleaning.

8. Risoluzione Dei Problemi

  • Il laser non funziona o ha un output debole:
    - 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.
  • Allarme surriscaldamento:
    - 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.
  • Problemi di compatibilità:
    - 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. Suggerimenti per l'utente

  • Taglio ottimale: 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.
  • Impostazioni software: 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.
  • Prove sui materiali: Always perform small test cuts or engravings on scrap material to fine-tune your power and speed settings before starting a larger project.
