Lùmen — GRBL Laser Engraver Software for Mac LightBurn Alternative

Lùmen is a native macOS laser engraver controller for GRBL machines. It allows users to design, engrave, and cut various materials with precision. The software features a built-in shape and text editor, image engraving capabilities, and SVG vector cutting. Users can import images in PNG, JPEG, BMP, or TIFF formats and convert them to GCode using seven dithering algorithms, grayscale mapping, or threshold. The software also supports loading SVG files for precise vector cutting. The application's interface is designed to be clean and native to macOS, allowing users to draw shapes and text directly on the canvas without needing external software like Inkscape or Illustrator. It includes features such as a multi-item layer panel, precise positioning and rotation, and editable project files. Lùmen works with various GRBL-based laser engravers, including Sculpfun, Ortur, Atomstack, TwoTrees, and NEJE. The software prioritizes safety with features like a 5-second countdown before every job, auto-homing, and automatic laser-off at job completion. It also includes 18 material presets and allows users to create custom presets. Lùmen offers a free 3-day trial, after which it costs €9.99. The application requires macOS 15 Sequoia or later and does not require a credit card for the trial. Users can resume work from the exact line where they left off if interrupted, and the software automatically checks for updates.
