Paste or upload your GCode and view the toolpath in interactive 3D. Rotate, pan, zoom, replay the cut, and read the exact dimensions. Everything runs in your browser — your file is never uploaded anywhere.
Supports G00/G01 moves and G02/G03 arcs, in millimetres (G21) or inches (G20). Cut moves shade white→blue by depth; rapid moves show as faint dashed lines.
Estimated from each machine's feed, rapid, and acceleration limits — short moves that never reach full speed are timed accordingly, so lighter machines take proportionally longer. Cut moves use the file's feed rate capped at each machine's ceiling.
