About
CutArc is free, browser-based CAD/CAM software that takes your plasma CNC table from design to cut — no installs, no subscriptions, no limits.
The Product
CutArc is a complete plasma cutting workflow tool that runs entirely in your web browser. Design shapes from scratch, import DXF and SVG files, trace raster images, configure machine-specific cutting parameters, and export production-ready G-code — all in one place.
It supports 12+ CNC controllers including Mach3, LinuxCNC, GRBL, Langmuir FireControl, Hypertherm EdgeConnect, and more. Whether you run a DIY plasma table in your garage or a production shop with a Hypertherm system, CutArc generates code tuned for your specific controller.
Every feature is available for free. No feature gating, no trial expirations, no "upgrade to export" walls. We believe professional-grade CAM software should be accessible to every operator who needs it.
Our Story
Most plasma table operators face the same frustrating choice: pay hundreds for desktop CAM software that does far more than they need, or piece together a fragile chain of free tools — Inkscape for design, a DXF converter, a separate CAM program, and a post-processor that may not match their controller.
CutArc was built to close that gap. One tool, zero cost, zero installation. Open your browser, design or import your part, set your cut parameters, and export G-code ready for your machine. It's purpose-built for plasma cutting — not a general-purpose CNC tool with plasma support bolted on as an afterthought.
We're a small team of CNC enthusiasts and software engineers who got tired of watching talented fabricators waste time fighting their software instead of cutting metal. Every feature in CutArc exists because a real operator needed it, and every controller profile has been tested against real machines.
