G-Code Review Desk
Open your G-code text, inspect an isometric or orthographic path, step through source-linked movements and export a numeric review. Unsupported state changes stop interpretation, so the tool never silently invents the remaining machine path.
How we build a check
This workbench processes supported inputs locally. We test calculations, file structure and generated artifacts using independent readers or known fixtures where available. The example runs the same processing path as a supplied input; it does not stand in for checking your own result.
Editorial responsibility
KitForma maintains this tool and its guides. The source notes on the tool page link to the supporting documentation. We do not claim affiliation with the referenced hardware manufacturers or platforms. Review date: 2026-10-19.
Limits and updates
UTF-8 text up to 2 MiB, 50,000 lines, 20,000 movements and 200,000 preview points. Review stops when a limit is reached. XYZ coordinates are limited to +/-1,000,000 mm.,Only the published subset is interpreted: XY incremental-center I/J arcs, not R arcs, other arc planes, macros, cycles, work offsets, rotary axes, extrusion, cutter compensation or tool-length offsets. Default initial state is visible in every report.,No machine connection or execution, stock removal, collision, tool shape, controller verification or manufacturing approval. Preview arcs use 2-degree chords; distances use analytic arcs. Time excludes acceleration and machine actions. If a specification changes or a result appears incorrect, send the relevant source URL and a non-sensitive reproduction to kitforma@outlook.com.
