Free, open-source CAD/CAM: draw, nest, prepare toolpaths and generate machine code.

Download for Windows (64-bit) Build on Linux All releases

Windows

  1. Unzip the archive anywhere and run openpostpro.exe. Nothing is installed and no administrator rights are needed.
  2. Install Python 3.12 or later with "Add Python to PATH" checked. OpenPostPro does not ship Python; it uses it for post-processors and CAD scripts. Without it Windows reports "python3.dll was not found" at startup.
  3. Install the Microsoft Visual C++ x64 Redistributable if it is not already on your PC.

If Windows shows "Windows protected your PC": "More info", then "Run anyway".

Linux

There is no ready-to-use archive for Linux yet: the application is built from source with CMake. The steps are in the Linux build guide.
