FAQ

What Java version do I need? Java 21 or later. Use any JDK distribution — your package manager, your OS vendor, or a download from openjdk.org.

Does MapleCAM require an internet connection? No. The only network call is a small update check on startup that fetches /api/version.json from this site to see if a newer version is available; it fails silently when offline and sends no project data.

What CNC machines does MapleCAM support? Anything that accepts GRBL or LinuxCNC G-code. More dialects are planned.

Can I import 3D models? No. MapleCAM is 2.5D, working from 2D designs (SVG, DXF). 3D surface carving is on the roadmap.

Is MapleCAM really free? Yes. No account, no subscription. If you find it useful, donations are welcome.
