CNC G-code Viewer

The CNC G-code Viewer ingests G-code programs, parses them, and renders toolpaths to validate geometry, motion constraints, and feed-rate implications. It supports common dialects and presents a clear map from code to movement.
It tokenizes lines, reconstructs coordinates, units, and feed rates, and builds a sequence of moves that can be reviewed as data and as a visual overlay.
Beneficiaries include CNC programmers, machinists, educators, and integrators; the tool helps identify potential collisions, excessive moves, or slow transitions before cutting.
Its unique value lies in dialect-agnostic parsing, immediate feedback, and exportable summaries that connect G-code to actual paths. Core features include a G-code loader, unit handling, path construction, color-coded feed-rate display, and export options for reports or data dumps.
