Lùmen

About

Lùmen is a macOS application designed for hobbyist laser engraving. It connects via USB to GRBL diode lasers from brands like Sculpfun, Atomstack, Ortur, NEJE, and TwoTrees. The software supports image engraving with seven dithering algorithms, SVG cutting, dual-layer projects, and material presets, all within a clean SwiftUI interface that integrates seamlessly with macOS. As a Mac-first alternative to LightBurn, it is available for a single payment of €9.99 with no subscription required. The app was created by an independent developer who wanted to avoid using Windows virtual machines to operate his Sculpfun laser.
