About g-code.xyz – Online CNC Simulators and Learning Tools
g-code.xyz is a free online platform for machinists, setters, students and technical educators. It provides lightweight tools for working with G-code and checking toolpaths directly in a web browser, without specialist software or complex setup.
What you will find on this portal:
- Turning simulators (2D and 3D): Visualize tool movement, toolpaths and material removal. Advanced versions also support C-axis positioning and the Y axis for milling with driven tools.
- Milling simulators: Verify milling toolpaths in 2D and 3D, including linear and circular interpolation.
- Integrated 2D CAD and G-code generators: Quickly sketch a 2D contour and export it as machine NC code.
- Text and image converters: Automatically convert lettering and images into G-code engraving paths.
- Interactive CNC learning games: Practice spatial thinking, coordinates and MDI input with training arenas and games.
- Video tutorials and guides: Practical setup demonstrations, explanations and tips from the workshop and classroom.
Workshop safety recommendation
The simulators are intended for education, preliminary program-logic checks and approximate toolpath geometry verification. Always carefully verify NC code in your machine control graphics before running it on a real machine. For the first part, use reduced rapid-traverse speeds and check collision zones.
