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 shows you
- Reconstruct and visualise the printed (or machined) object straight from G-code: every extruded move is drawn as a line in an interactive WebGL viewer, height-coloured and Z-up, with a build-height scrubber to peel the print back layer by layer. Works universally across slicers (PrusaSlicer, SuperSlicer, OrcaSlicer, Cura, ideaMaker, Bambu Studio, Simplify3D) and CNC / laser CAM, handling absolute and relative moves, inch and millimetre units, and G2/G3 arcs; travel moves are separated out. Reads the slicer or CAM tool, object size, layer count and height, filament or cut-path length, feedrate range, and nozzle/bed temperatures.
- Open a .GCODE file
- Drag a .GCODE file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
