CAMotics — The Complete Guide: Simulate G-code Before the Machine Starts Cutting
CAMotics is an open-source machining simulator: load a G-code file, define a tool and a block of stock, and see in 3D what will remain after cutting. Five minutes of simulation saves stock and broken tools.

- 3D material removal — the machined result on the stock.
- A tool table — diameter, length and tip shape for each tool.
- Path display — cutting and rapid moves in different colours.
- Standard G-code — files from any CAM system.
- A scripting language — generating toolpaths in code.
Which mistakes it catches
A rapid move into the material, a tool that never reaches depth, a collision with the clamps, or a path that produces a different shape than you expected. Run every new file — especially after changing a post-processor or a tool. The simulation checks geometry, not cutting forces or machining conditions.
