Orca Slicing Checklist — LUME v1

> Stale slicing checklist, 2026-04-30: this references the old `exports/` part set and Jetson-era internals. Use `../PRINT_APPROVAL_QUEUE_CURRENT.md` and rebuild from `../exports/approval-v2/` or `../exports/approval-symmetric/`. Per-part GUI walkthrough for OrcaSlicer (macOS). All parts already verified: all 10 `internal_*.stl`, 4 shell halves, 4 coupons present in `hardware/cad/exports/`. - **Printer**: Elegoo Neptune 4 Max (420×420×480, X cap 420 mm) - **Filament**: ASA grey, 240 °C nozzle, 100 °C bed - **Profile**: `0.20mm Standard` - **Walls**: 4 - **Top/Bottom**: 5 / 5 - **Infill**: 25 % gyroid - **Supports**: see per-part column - **Brim**: 5 mm on shells (warp control) - **Cooling**: ASA defaults (low; layer time ≥ 12 s) - **Z-seam**: aligned, rear-facing for shells - **First-layer flow**: 100 %, line width 0.45 ## Order — runs sequentially. Coupons first; do not start shells until splice fit verifies. | # | 3MF | Parts | Layout hint | Supports | ETA | Gate | |---|-----|-------|-------------|----------|-----|------| | 1 | `01_coupons.3mf` | coupon_grooves, coupon_splice_pegs, coupon_splice_pockets, coupon_tongues | 2×2 grid centered | none | 2 h | hand-fit pegs into pockets after print | | 2 | `02_internals_batch.3mf` | all 9 `internal_*.stl` (jetson_sled retired 2026-04-26 — K11 lives in pod) | auto-arrange; verify no clip | tree, only on overhangs >55° | 5 h | check internal_femto_mount snap-fit; pod_compute_sled prints separately on plate 07 | | 3 | `03_shell_front_L.3mf` | shell_front_L.stl | flat, femto bay up, X≤330 | tree on; paint-supports under wordmark recess | 10 h | verify splice tongues fit coupon_grooves | | 4 | `04_shell_front_R.3mf` | shell_front_R.stl | flat, cam_right facing up | tree on | 5 h | dry-fit against L half | | 5 | `05_shell_rear_L.3mf` | shell_rear_L.stl | VESA face down, ports up | tree on; bridges over grille | 10 h | check ESD pad clearance | | 6 | `06_shell_rear_R.3mf` | shell_rear_R.stl | flat, port cluster up | tree on | 5 h | dry-fit; full assembly check |
