STEP to verified slicing mesh and slicer estimates

Turn a CAD model into a sliced print plan with time and filament estimates, without touching the printer.

INTEGRATED , rung 4 of 8 Recorded 22 September 2026. Advanced Systems branch, not merged into production.

Technical

What it is

freecad.step_print_mesh converts STEP to STL (installed OrcaSlicer 2.4.2 rejected STEP input; that failure is preserved as a receipt); StagingArea.stage_asset / stage_scene / publish_estimates; estimates feed engineering runs.

Truth ladder

Where it stands

Rung 4 of 8: INTEGRATED

Wired into the rest of JARVIS and tested across component boundaries.

Project record: integrated and live-proven on fixtures (handoff)

  1. CONCEPT Designed or specified. No working code yet.
  2. IMPLEMENTED Code exists. Nothing has demonstrated that it behaves correctly.
  3. TESTED Automated tests exercise it in isolation, often against fixtures.
  4. INTEGRATED Wired into the rest of JARVIS and tested across component boundaries.
  5. PRODUCTION-REACHABLE The owner can reach it through the real runtime path, not only through a test harness.
  6. LIVE-PROVEN A bounded probe ran the real code path on a booted JARVIS on the real machine and recorded evidence. The project treats live evidence as expiring after 24 hours, so every live reading here shows the date it was taken.
  7. FORMALLY VERIFIED Its critical property is checked by a proof or exhaustive verification.
  8. RELEASE-QUALIFIED Passed every qualification gate for a named release.

Limits

Limitations

  • Synthetic fixture example: a 10 mm cube estimated at 325 s / 0.73 g. No printer transmission or start occurred; software readiness is separate from physical authorization. Advanced Systems work lives on 2026-09-22 branches, not the production branch; most later commits are marked PENDING_PRIMARY_RELEASE under a measurement hold.
