A suite of CAM tools that run entirely in your browser. No installation, no accounts, no cloud processing - your files never leave your machine.
Both apps sit on shared foundations: analytic file parsing, a Clipper2/WASM geometry pipeline that reconstructs almost lossless arcs after boolean operations, three-stage toolpath planning with G2/G3, plus ten post-processors and counting. Each app wraps that engine in a UI and an operation set built for specialized workflows.
Turns Gerber, Excellon and SVG into G-code for isolation milling, or into precision SVG/PNG for laser and vinyl work. Meant as an alternative to FlatCAM.

Isolation routing · copper clearing · drilling · board cutout with tabs · solder paste stencils · a fiber/UV laser pipeline (beta).
General routing from vector and mesh sources, from flat SVG cutting through 3D surfacing and 4th-axis work. Planned as a replacement for Easel, it now offers more operational choices and better quality toolpaths (thanks to analytic G2/G3 arcs).

| Input | Gerber, Excellon, SVG | SVG, STL |
| Model | one file per operation | per-shape operation buckets |
| Transforms | board-level | per-shape/nested group |
| Undo/redo | no | full command history |
| Machines | CNC router, laser/drag knife | CNC router |
| 3D operations | no | V-carve, relief, rotary |
| Output | G-code, plus SVG/PNG | G-code |
- Parsing - Gerber (RS-274X), Excellon, SVG (full path spec including arcs and Béziers), STL (binary and ASCII).
- Geometry - Clipper2 via WebAssembly for booleans, with arc reconstruction so exported arcs use G2/G3 arcs insted of tessellated polylines.
- Toolpaths - translate geometry to motion, optimize (staydown clustering, nearest-neighbour ordering, collinear simplification), then inject machine specifics: rapids, plunges or helical entries, holding tabs, rotary routes.
- Rendering - a custom 2D canvas renderer with batching, level-of-detail and viewport culling, plus a three.js 3D preview for toolpaths and stock. With simulation to come soon™.
- Frontend - vanilla JavaScript (ES6+), HTML5, CSS3. No framework, and no build step required for development or local deployment.

Developed and tested against KiCad and EasyEDA output.
Exporting Gerber with Protel extensions lets drag-and-drop auto-assign files to the right operation.
Bézier curves are parsed analytically but interpolated to line segments before offsetting - analytic Bézier offsetting is not supported yet.
Having access to a limited number of machines/controllers/setups means the project depends on community feedback about what works or doesn't for most hardware/setup combinations. While the geometry system has been tested thoroughly, the recent additions of tool-changing and 4th-axis logic mean a lot more variables have been added which haven't been fully tested in all possible controller configurations, so proceed with some caution and report any unexpected behaviour.

EasyTrace5000 supports keyboard-only navigation and screen readers. See the accessibility guide (source: easytrace5000/doc/ACCESSIBILITY.md) for the full shortcut list and current WCAG 2.1 status.
One shared engine at the repository root; each app directory adds a UI, an operation set and a profile. Repository layout, local setup, the production build and the debug console commands are in ARCHITECTURE.md.
git clone https://github.com/RicardoJCMarques/EasyCAM5000.git
cd EasyCAM5000 && npx serve # a local server is required; file:// will not workSuite version 1.6.2 - see the changelog. Versions track the suite as a whole; entries name the app they affect.
Anything else lives in the issue tracker.
- Multi-lingual UI - the string layer exists, only English is populated
- Tool library, post-processor and theme import/export
- Toolpath playback and material removal simulation in the 3D preview
- Service Worker for offline use
I am not actively seeking code contributions, but testing reports are the most useful thing anyone can send - especially confirmation that a post-processor works on real hardware.
