- 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.
