Requires macOS 15 Sequoia or later

Everything you need to engrave & cut

Professional tools in a clean, native macOS interface

🖼

Image Engraving

Import any image and convert it to GCode with 7 dithering algorithms. Adjust brightness, contrast, resolution, and power in real-time.

SVG Vector Cutting

Load SVG files for precise vector cutting. Supports paths, rectangles, circles, ellipses, arcs, and bezier curves with configurable speed, power, and passes.

📐

Dual Layer System

Combine engrave and cut layers in a single job. Each layer has independent positioning, sizing, and settings — like working in Photoshop.

🎯

Precise Positioning

Move and resize layers with drag & drop or type exact X, Y, W, H values in millimeters. Frame your job boundary before engraving.

🔍

7 Dithering Algorithms

Floyd-Steinberg, Atkinson, Burkes, Jarvis-Judice-Ninke, Sierra, Sierra Lite, and Stucki. Pick the best one for your material and style.

🛡

Safety First

5-second countdown before every job. Auto-homing, soft jog limits, overscan clamping, and automatic laser-off at job completion.

📊

Power/Speed Test Grid

Generate calibration grids to find the perfect settings for any material. Configurable speed range, power range, cell size, and resolution.

🔄

Resume from Position

Stopped mid-job? Resume from the exact line where you left off. No need to start over.

Full GRBL Control

Serial console, real-time status, feed & speed overrides, jog controls, alarm management — everything you need, nothing you don't.
