CAMotics is a CNC simulation and computer-aided machining application that lets you load 3-axis GCode programs, visualize tool paths in 3D, and preview the resulting cut workpiece before running a job on a real machine.
It’s aimed at CNC users who want to catch mistakes early, reduce wasted material, and experiment with toolpaths in a safer environment. CAMotics runs on Linux and is also available for macOS and Windows.
This is free and open source software.
Key Features
- Simulates 3-axis CNC GCode programs with 3D cut-workpiece visualization.
- Provides tool path visualization to inspect machining operations before cutting.
- Supports multiple tool shapes including cylindrical, conical, ballnose, spheroid, and snubnose tools.
- Parses, simulates, verifies, and annotates GCode programs.
- Includes in-application viewing and editing for GCode and TPL files.
- Supports LinuxCNC O-codes.
- Exports the cut workpiece to STL format.
- Offers tool table editing.
- Adds height probing to 2D GCode files for tasks such as PCB cutting and metal engraving.
- Uses multi-threaded rendering to take advantage of multi-processor CPUs.
- Cross-platform support – runs under Linux, macOS, and Windows.
