What it is
- Code editor — Monaco with syntax highlighting, autocomplete, hover docs
- Bidirectional sync — Select lines in editor ↔ highlight in 3D; click toolpaths in 3D → jump to code
- Analysis — Outline tree (startup, layers, regions, shutdown), metrics (time, filament, flow)
- Visualization — 8 color modes: speed, flow, temperature, fan, layer, and more
- Tools — Change speed/flow/temperature on selections, reorder sections, snapshot and diff
What you can do
- Post-process slicer output — Adjust speeds, add pauses, insert custom commands
- Inspect any G-code — Visualize toolpaths from any slicer with color-coded overlays
- Debug line by line — Step through commands and inspect full machine state
- Compare edits — Snapshot your work and diff against previous versions
