Features
Design, configure, and cut — without switching between multiple desktop applications.
Assign shapes to layers with individual speed, power, and priority settings. Configure cut and engrave layers independently.
Drag and drop SVG files onto the bed. Paths are automatically parsed and ready for layer assignment and cutting.
See your full laser bed with a zoomable, pannable canvas. Position shapes precisely with snap-to-grid and dimension readouts.
Connect to Ruida controllers via WebUSB or Serial, and GRBL boards via Serial. Send jobs, frame the work area, and start cuts — all from Chrome.
Draw rectangles, circles, lines, and polygons directly on the bed. Click and drag to create shapes with real-time dimension previews.
Browse and use ready-made designs from the shared CutArc design library. One free design per week included with every account.
Job Preview
Preview your job before sending it to the machine. Choose a material finish, adjust kerf width, and toggle cut gap visibility to catch issues before they waste material.
Photo Engraving
Import photographs and convert them to laser-ready scan data with adjustable dithering, brightness, contrast, and DPI settings. Material presets for plywood, acrylic, and more.
