What is a .NC file?
NC files hold G-code for CNC machines - the name stands for Numerical Control. Produced by CAM software.
- Did you know
- "NC" means Numerical Control, the 1950s technology that G-code grew out of.
- Numerical control traces back to the MIT Servomechanisms Laboratory in the 1950s, where the first such programming was developed.
- APT, the Automatically Programmed Tool language developed at MIT in the late 1950s, became the first widely used way of writing programs for NC machines.
- 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
- .NC 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 .NC file
- Drag a .NC 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.
