What is a .CNC file?
A .cnc file holds machine instructions for a CNC mill, router or cutter. Produced by CAM software.
- Did you know
- CNC stands for Computer Numerical Control, the technology behind automated machining.
- Most .cnc files contain G-code, a machine language first standardised in the United States as EIA RS-274 and later by ISO as 6983.
- The numerical-control language behind these files traces back to MIT researchers automating milling machines in the late 1950s.
- What Analyser reads
- Analyse G-code for 3D printers and CNC machines - detect the slicer or CAM tool, machine and controller, toolpath, and print or cut dimensions (Prusa, Bambu, Cura, Fusion 360, Mastercam, GRBL, Fanuc, Haas).
- Depth of analysis
- .CNC is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .CNC file
- Drag a .CNC file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
