G-code Viewer

See what you're about to print. G-code Viewer renders the real toolpaths from any .gcode file, every layer, every move, so you can sanity-check a sliced model before it reaches the printer. It also reads Prusa's binary .bgcode.

Quick Look integration puts the preview right in Finder — press Space on any G-code file.
