LinuxCNC: Open Source Computer Control for CNC Machines

LinuxCNC is an open source software system for computer control of machines such as milling machines, lathes, plasma cutters, robots, and more. It can control up to 9 axes of motion with sub-micrometer resolution.

What is LinuxCNC?

LinuxCNC is an open source software system for computer control of machines such as milling machines, lathes, plasma cutters, laser cutters, water jet cutters, routers, robots, hexapods, and more. It can control up to 9 axes of motion with sub-micrometer resolution.

LinuxCNC takes advantage of the real-time capabilities of Linux to deliver high performance and accuracy. It interfaces with a wide variety of hobbyist and industrial grade motor drives, servo drives, stepper drives and IO cards. Stepper motors, servo motors, relay cards, etc. everything needed to control your machine is supported one way or another.

LinuxCNC is suitable for machining parts, making your own CNC machine, doing photochemical machining, sculpting foams, organic materials, wax, wood, plastics and metals, abbreviated as the Other Machine Tool (OMT). It can run 3d printers, foam cutters, machine vision systems, robot arms and crank operated machines as well.

The LinuxCNC development team focuses on code quality and stability over new feature development. It aims to provide the best stability and most accurate performance from your hardware.
