When using LightBurn with the Longer Nano Pro laser engraver, adjusting the correct settings is important for achieving high-quality engraving results. Among these settings, Line Interval is one of the key parameters that affects image detail, engraving speed, and the final visual effect.
This guide explains what Line Interval means, how it changes engraving results, and how to choose the right setting for different projects.
1. What Is Line Interval in LightBurn?
Line Interval, also called line spacing, refers to the distance between two adjacent engraving lines during the laser engraving process. This setting controls how closely the laser scans the material surface.
A smaller Line Interval means the laser creates more scan lines, which can improve image details. A larger Line Interval reduces the number of scan lines, which can shorten engraving time. This setting directly affects image sharpness, detail resolution, and processing time.
2. How Line Interval Affects Laser Engraving Quality
The best Line Interval setting depends on the material, design details, and expected engraving effect.
2.1 Effect on Image Engraving
Material Type:
Different materials respond differently to line interval settings. For instance, wood and acrylic may exhibit vastly different engraving results at the same interval.
Engraving Detail:
When engraving highly detailed designs or fine text, a smaller line interval typically produces better results. The laser head covers more surface area, reducing gaps and improving image precision.
Engraving Speed:
A larger line interval can reduce the overall engraving time, but it may also lead to loss of fine detail—especially in intricate designs.
2.2 Effect on Material Removal
Material Response:
On some materials like wood, a very small line interval can cause overburning or excessive material removal. On the other hand, for metal or glass, a carefully chosen interval can help maintain clean and precise engraving without damaging the surface.
2.3 Effect on Texture and Visual Style
Visual Style:
Line interval not only affects clarity but also contributes to the overall artistic style. A smaller interval provides smoother gradients and shading, while a larger interval can produce visible scan lines, which may be desirable for certain stylized effects.
3. How to Adjust Line Interval in LightBurn
Follow these steps to change the Line Interval setting in LightBurn:
- Open LightBurn and import your image.
- On the right side of the interface, open Cuts / Layers.
- Double-click Layer 00 to open the Cut Settings Editor.
- Find Line Interval.
- Enter the required value according to your project.
4. Recommended Nano Pro Line Interval Values
0.03 mm:
Ideal for projects requiring high detail, such as fine patterns or small text. Offers maximum coverage but significantly increases engraving time.
0.06 mm:
A well-balanced option suitable for most materials and general engraving tasks. It provides solid detail reproduction while maintaining reasonable engraving speed. (Highly recommended)
0.09 mm:
Suitable for simpler designs or when faster processing is required. This interval increases speed but may sacrifice some fine detail in more complex images.
0.12 mm:
Best used for basic designs or large fill areas where speed is more important than precision. This setting greatly reduces engraving time but is not ideal for detailed work.
5. Conclusion
For Longer Nano Pro users working with LightBurn, Line Interval is an important setting that affects both image quality and engraving efficiency. A smaller Line Interval can improve details and smoothness, while a larger Line Interval can save processing time.
By selecting the right Line Interval based on your material and design requirements, you can achieve a better balance between engraving speed, image clarity, and final results.
