Common performance issues in laser engraving can significantly affect the quality of the final product. Here are some ways to identify and resolve these issues:

• Inconsistent Speed: If the engraving speed varies, it can lead to uneven marking. Check the machine settings and ensure that the motor functions smoothly. Adjust the speed settings as needed.
• Poor Quality of Engraving: Blurry or faint engravings may indicate issues with focus. Regularly check and maintain the focus lens. Optimize the focus height to ensure a sharp engraving.
• Material Flickering or Burn Marks: This may be caused by incorrect power settings. Adjust the power settings according to the material being used, and perform test runs to determine optimal levels.
• Inaccurate Dimensions: If the engraving does not match the intended design, inspect the machine for alignment issues. Ensure mirrors and lenses are aligned correctly.
• Smoke and Residue Build-Up: Excessive smoke can indicate incorrect airflow. Clean the ventilation system and consider adding air assist to improve engraving cleanliness.

Regular maintenance and attention to machine settings can significantly reduce these performance issues and enhance the quality of laser engraving.
