Burin

Design it, then carve it.

Draw your parts, prepare the toolpaths and write the file your CNC machine reads. In English or French, on Windows, Linux or in your browser.

A part carved in Burin's 3D preview, in a beech board

Burin has never driven a real machine yet. Check every file in a simulator, then run it in the air, with the bit well above the material, before you cut.

How it works

  1. 1

    Draw the part

    Set the size of your board, then draw shapes and text, or open an SVG, DXF or .crv3d file.

  2. 2

    Choose how to cut

    Pick a bit and a toolpath: cut out, pocket, engrave or carve in 3D. The 3D preview shows the result in wood before you cut.

  3. 3

    Save the machine file

    Choose your machine's controller and save the G-code. Check it, run it in the air, then cut.

What it does

Draw

Lines, curves, circles, polygons, stars, text with your computer's fonts or single-line fonts for engraving, dimensions and constraints.

Model in 3D

Components, reliefs from pictures or STL, sculpting, emboss, two-rail sweep, extrude and weave.

Machine

Profile, pocket, drilling, engraving, V-carving, 3D roughing and finishing, with ramps, leads, tabs and adaptive clearing.

Nest

Several sheets per job. Parts are laid out in rows or by their true shape, turned, put in the holes of bigger ones, or fitted in an outline.

Check

A 3D preview of the cut, the machining time, a check before cutting and a job sheet to print.

Write and exchange

G-code for GRBL, Mach3, LinuxCNC, PlanetCNC or your own post processors. Opens .crv3d projects, SVG, DXF and STL.

Questions

Is it really free?

Yes. Burin is free software under the GNU GPL: you can use it, share it and change it, with no account, no subscription and no advertising.

Which machines does it work with?

Burin writes G-code for GRBL, Mach3, LinuxCNC and PlanetCNC controllers, and for others through post processor files (.pp). It doesn't drive the machine itself: you open the saved file in your machine's control program.

Can I open my .crv3d projects?

Yes: Burin reads .crv3d files, with their shapes, toolpaths, guides, grid and notes. Some 3D parts of a project aren't read yet. It also opens SVG, DXF, STL and pictures.

Is it safe to use on my machine?

Burin hasn't been tried on a real machine yet, so treat every file as untested: check it in a simulator, run it in the air with the bit well above the material, and keep a hand near the emergency stop.

Does it need the internet?

No. The Windows and Linux programs work fully offline. The browser version needs the internet to load once, then everything is computed in the page.

How do I report a problem?

In Burin, Help > Send Feedback opens a draft you can read before sending; your work and file names are never in it. You can also open an issue on GitHub.
