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.
