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)
- CONCEPT Designed or specified. No working code yet.
- IMPLEMENTED Code exists. Nothing has demonstrated that it behaves correctly.
- TESTED Automated tests exercise it in isolation, often against fixtures.
- INTEGRATED Wired into the rest of JARVIS and tested across component boundaries.
- PRODUCTION-REACHABLE The owner can reach it through the real runtime path, not only through a test harness.
- 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.
- FORMALLY VERIFIED Its critical property is checked by a proof or exhaustive verification.
- 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.
