Native macOS GRBL Controller for Sculpfun, Ortur, Atomstack & More
A native, fast, and precise tool to control your GRBL-based laser engraver. Engrave images, cut SVG vectors, and fine-tune every parameter — all from your Mac.
No credit card required. Requires macOS 15 Sequoia or later.
Professional tools in a clean, native macOS interface
Import PNG, JPEG, BMP, or TIFF images and convert to GCode with three modes: 7 dithering algorithms, grayscale mapping, or threshold. Adjust brightness, contrast, and resolution with real-time preview.
Load SVG files for precise vector cutting. Supports paths, rectangles, circles, ellipses, arcs, and bezier curves with configurable speed, power, and passes.
Combine engrave and cut layers in a single job. Each layer has independent positioning, sizing, and settings — like working in Photoshop.
Move and resize layers with drag & drop or type exact X, Y, W, H values in millimeters. Frame your job boundary before engraving.
Floyd-Steinberg, Atkinson, Burkes, Jarvis-Judice-Ninke, Sierra, Sierra Lite, and Stucki. Pick the best one for your material and style.
5-second countdown before every job. Auto-homing, soft jog limits, overscan clamping, and automatic laser-off at job completion.
Generate calibration grids to find the perfect settings for any material. Configurable speed range, power range, cell size, and resolution.
Use machine homing or set a custom origin anywhere. Supports bottom-left and center alignment. Jog to position, set zero, and start engraving.
Toggle a low-power laser dot to preview exactly where your engrave will land. Frame mode traces the full job boundary with the laser.
Save both layers, settings, and positions into a single project file. Reopen later and everything is exactly where you left it.
Stopped mid-job? Resume from the exact line where you left off. No need to start over.
Serial console, real-time status, feed & speed overrides, jog controls, alarm management — everything you need, nothing you don't.
Ready-to-use presets for wood, leather, paper, cardboard, cork, acrylic, aluminum foil, and more. Create and save your own custom presets for any material.
Lùmen checks for updates automatically and lets you know when a new version is available. Always stay up to date.
