LightBurn is a software program used to design, edit, and control laser cutting and engraving machines. It allows users to import vector files, trace images, edit designs, and create custom text for engraving. It is CAM for laser cutters.
A DXF file is a standard vector format commonly exported from CAD software. To bring a DXF into LightBurn, open the software and select File → Import or use the shortcut Ctrl + I. Once imported, the DXF will appear in the workspace and can be moved, scaled, or rotated. If the file imports with unexpected scaling, go to…
Edit → Settings → Import/Export → DXF Import Settings → *select your preferred units*
LightBurn provides multiple tools for editing imported or drawn vectors. Selecting a line or shape allows access to node editing with the Edit Nodes tool (N). Individual points can be moved, added, or deleted to refine geometry. The Boolean Operations menu allows users to combine, subtract, or intersect shapes. For alignment, the toolbar includes snapping options and alignment commands to distribute shapes evenly.
Raster images, such as JPEGs or PNGs, can be converted into vector shapes using LightBurn’s trace tool. After importing an image, select it and choose Tools → Trace Image. The trace window provides adjustable parameters such as threshold and smoothing. Higher threshold values capture darker details, while smoothing reduces jagged edges. Once traced, the vector version can be edited like any other shape, while the original bitmap can be deleted or hidden.
Text can be added directly in LightBurn using the Text Tool (T). Clicking on the workspace opens a text box where letters, numbers, and symbols can be typed. The font, size, spacing, and alignment can be adjusted in the text properties panel. For laser operations, text can be set as a vector cut, an engraved fill, or combined with other shapes for decorative layouts. Converting text to paths (Ctrl + Shift + C) allows node editing and shape modification.
LightBurn includes layers for organizing different parts of a design. Each layer can be assigned settings for speed, power, and laser mode (cut, engrave, or score). Designs can also be previewed with the Preview Tool to simulate how the laser will run. Understanding these controls ensures precise results and efficient material use.
