Spin the stock. Read the signal.
Free (and pro version) 4-axis rotary CAM and G-code generator for DIY CNC. Turn an STL or STEP into simultaneous 4-axis rotary toolpaths, wrapped engraving, and a verified material-removal simulation on Windows, without a CAM subscription.
⚠️ EXPERIMENTAL. RotatoCAM only writes a G-code file; it does not run your machine, and its output is only a suggestion you must verify. CNC machines are dangerous. You alone are responsible for inspecting every program, air-cutting first, and operating safely. Provided AS-IS, with no warranty.
Grab the free Community Edition at rotatocam.com. Unzip and run: no install, no license, no expiry.
Everything else lives there too: what it does, the how-to, the gallery, the safe-testing guide, supported controllers, and RotatoCAM Pro.
