Line interval is a key setting in LightBurn that directly impacts engraving detail, visual quality, and processing time. This guide uses the LONGER NANO Pro to demonstrate how different line intervals—from 0.03mm for high-detail work to 0.12mm for fast, low-detail tasks—can dramatically change the outcome of your laser projects. By understanding and adjusting this parameter, users can achieve the perfect balance of precision, efficiency, and artistic style in their engravings.
