G-Code Modifier

A browser-based G-code editor and 3D print analyzer. Inspect layers, simulate prints, detect failures before they happen, and modify G-code — all without installing anything.

Try it live — no download required.

G-Code Modifier 3D View


Highlights

3D Visualization 3D Visualization — WebGL layer viewer with motion-type coloring, travel moves, cross-section clipping, and interactive camera controls.
Print Analysis Print Analysis — Thermal simulation, structural analysis, and motion kinematics with 12 heatmap overlay modes. Detect failures before they happen.
Warp Prediction Warp Prediction — 3D deformation mesh with material-aware failure prediction and adjustable deformation preview.
Hole Detection Hole Detection — Scan layers to find holes for magnets, threaded inserts, or nuts. Auto-calculate insert depths and add pauses.
