Total Machine Control.

The ultimate G-code debugger. See exactly what your printer will do before it moves. Edit, analyze, and optimize any toolpath—from any slicer or from 3dSynth.

Why it matters

Optimize speeds for material studies. Tune retraction and flow by region. Insert pauses, custom commands, or post-process slicer output—with full visual feedback and no guesswork.

What you get

  • 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

Use cases

  • Optimization — Tweak speed/flow/temperature by region; see the result in 3D before you print
  • Material studies — Compare temperature and flow profiles with color-coded visualization
  • Complex retraction tuning — Inspect travel moves and retractions; snapshot and diff to track changes
  • Post-process any slicer — Import Prusa/Cura/Bambu output; add pauses, custom M-codes, or fix artifacts
