What is a .GCODE file?
G-code is the instruction language that tells 3D printers and CNC machines how to move. Produced by slicers like Cura and PrusaSlicer.
- Did you know
- G-code dates back to the 1950s, when it was created at MIT for the first numerically controlled machine tools.
- G-code is standardised as EIA RS-274 and internationally as ISO 6983, with the “G” denoting its preparatory commands.
- A .GCODE file is plain text, so you can open and edit it in any text editor.
- 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
- .GCODE 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 .GCODE file
- Drag a .GCODE 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.
