LinuxCNC is an open-source machine control software that drives CNC machines such as milling machines, lathes, 3D printers, laser and plasma cutters, and robot arms. It accepts G-code input, runs under Linux with optional realtime extensions, and offers multiple GUIs and support for many hardware interfaces.
Use cases
- control a CNC milling machine with G-code
- retrofit an old lathe with modern machine control software
- drive a 3D printer or laser cutter from Linux
- control a robot arm or hexapod with G-code
- run a plasma cutter with rigid tapping and cutter compensation
- build a DIY CNC controller on a realtime Linux system
When to choose
- you need full-featured, proven open-source CNC control on Linux
- you want support for many machine types and hardware interfaces
- you need advanced features like rigid tapping and cutter compensation
- you want an active community and long-maintained project
When to avoid
- you need Windows or macOS-native machine control
- you require certified safety compliance - the software explicitly disclaims liability
- you want a plug-and-play commercial controller with vendor support
- you need a lightweight hobby firmware like Marlin or GRBL for a simple 3D printer
