What is a .TAP file?
TAP files hold CNC G-code, a nod to the old paper-tape programs machines once read.
- Did you know
- The extension recalls the punched paper tape that early numerically controlled machines read before computers were built in.
- TAP files are usually produced by CAM software such as Mastercam, which turns toolpaths into machine-ready G-code.
- Analyser handles .TAP alongside related formats such as .GCODE, .GCO, .G and more.
- 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 .TAP file
- Drag a .TAP 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.
