LUME Current Print Approval Queue

LUME Current Print Approval Queue

Date: 2026-04-30

Status update, 2026-05-20: the large printed outer shell and pod path is paused while the wood enclosure prototype is evaluated. Use `wood/LUME_WOOD_ENCLOSURE_SPEC.md` for the current wood-body direction and `print/WOOD_V2_PRINT_QUEUE.md` for the active 3D-print queue.

Active Wood V2 Print Queue

The active OrcaSlicer projects are now:

• `print/3mf-current/wood-v2/01_wood_v2_small_fit.3mf`
• `print/3mf-current/wood-v2/02_wood_v2_sensor_stack.3mf`
• `print/3mf-current/wood-v2/03_wood_v2_k11_sled.3mf`

The matching STLs are in:

- `exports/wood-v2/`

The reproducible OpenSCAD source is:

- `lume-wood-v2-printables.scad`

Do not print the old shell/pod plates for the wood enclosure build unless we explicitly return to the full ASA shell.

This is the current print queue for the K11 + top monitor + Femto Mega + Arducam build. The older 3MF queue files were generated before the K11 pod, top display cradle, and Arducam changes, so treat those prearranged plates as stale until rebuilt from the STL folders below.

Current OrcaSlicer approval projects were generated on 2026-04-30:

• Single-right Arducam: `print/3mf-current/approval-v2/`
• Symmetric dual Arducam: `print/3mf-current/approval-symmetric/`

These are 3MF project plates for review in OrcaSlicer, not final G-code. Apply the Elegoo Neptune 4 Max ASA profile, inspect supports/brims/toolpaths, then export G-code only after visual approval.

For the symmetric dual-Arducam internals, use:

- `print/3mf-current/approval-symmetric/02_internals_dual_arducam_ASA_READY.3mf`

Do not use the original symmetric internals file. It had a bad layout with objects off the bed and has been moved to:

- `print/3mf-current/approval-symmetric/legacy-broken-layout/02_internals_dual_arducam_DO_NOT_PRINT_broken-layout.3mf`

The current 3MFs have been patched for OrcaSlicer warnings:

• `before_layer_change_gcode` includes `G92 E0` so relative extrusion resets per layer.
• Conservative embedded acceleration values are set for review: `inner_wall_acceleration=500`, `travel_acceleration=500`, and `machine_max_acceleration_travel=1000`.
• Backups are in `print/3mf-current/.backup-before-g92/` and `print/3mf-current/.backup-before-accel-patch/`.
• The rebuilt symmetric internals plate was additionally validated through Orca GUI and Orca CLI. Final review outputs are in `print/gcode-review/symmetric-internals-asa-ready/`: `orca-gui-preview-final.png` and `plate_1.gcode`. This is for review only; do not send it to the printer until the physical layout is approved.

Current visual approval renders were generated on 2026-04-30:

• Single-right 4K Blender renders: `renders/blender-approval-single-4k/`
• Symmetric dual 4K Blender renders: `renders/blender-approval-symmetric-4k/`
• Combined 4K render sheet: `renders/blender-approval-4k-contact-sheet.png`
• Full-layout OpenSCAD sheets: `renders/approval/approval_bom_contact_sheet.png` and `renders/approval/approval_symmetric_contact_sheet.png`

For the combined 4K render sheet, read row 1 as single-right Arducam and row 2 as symmetric dual Arducam. Columns are 3/4, front, side, and macro. The OpenSCAD sheets show the full product layout more clearly; the Blender sheet is mainly for surface, window, and pod-service inspection.

Current Truth Files

Use these for the current build:

• `LUME_CURRENT_BUILD_SPEC.md`
• `LUME_SYMMETRIC_CAMERA_VARIANT.md`
• `FEMTO_MEGA_FIT_AUDIT.md`
• `LUME_DIMENSION_SOURCE_AUDIT.md`
• `LUME_WIRING_SERVICE_PLAN.md`
• `PRINT_APPROVAL_QUEUE_CURRENT.md`

Legacy/stale docs are marked at the top and should not drive final printing:

• `PRINT_PLAN.md`
• `DIMENSIONAL_AUDIT.md`
• `print-queue.md`
• `print/print-queue.md`
• `print/SLICING-CHECKLIST-MEGA-V2.md`
• `print/slicing-checklist.md`
• `CAD_APPROVAL_PACK.md`
• `README.md` for file map only, not active architecture truth.

Choose One Camera Variant

Single Right Arducam

• STL folder: `exports/approval-v2/`
• Final physical pieces: 15
• Total with coupons: 19
• Use when you want the cleaner asymmetric layout: centered Femto Mega plus one right-side IMX586 camera.

Symmetric Dual Arducam

• STL folder: `exports/approval-symmetric/`
• Final physical pieces: 16
• Total with coupons: 20
• Use when you want balanced left/right IMX586 cameras around the centered Femto Mega. Print `arducam_mount.stl` twice.

Plate 0 - ASA Calibration

• Part: Elegoo/default calibration cube or equivalent.
• Purpose: confirm bed adhesion, ASA chamber behavior, first layer, and dimensional shrink before printing LUME parts.

Plate 1 - Fit Coupons

Print these first and hand-fit before committing to large shell prints:

• `coupon_tongues.stl`
• `coupon_grooves.stl`
• `coupon_splice_pegs.stl`
• `coupon_splice_pockets.stl`

Approval gate: tongue/groove/splice fit should close by hand without forcing and should not rattle.

Current symmetric coupon review slice:

• Project opened in Orca GUI: `print/3mf-current/approval-symmetric/01_coupons.3mf`
• Preview: `print/gcode-review/symmetric-coupons-asa-ready/orca-gui-preview-final.png`
• Review G-code: `print/gcode-review/symmetric-coupons-asa-ready/plate_1.gcode`
• Orca estimate: about 4 h 44 min total, about 44 g ASA.
• Settings: ASA 260 C / 100 C, 0.20 mm layer height, 4 walls, 5 top/bottom layers, 25
• Note: the old coupon 3MF opens correctly in the GUI, but Orca CLI is unstable reading that 3MF. The review G-code above was generated directly from the four clean/manifold coupon STLs using the same ASA profile.

Current Polymaker ASA export for the actual grey spool:

• Project opened in Orca GUI: `print/3mf-current/approval-v2/01_coupons_POLYMAKER_ASA_READY.3mf`
• Preview: `print/gcode-review/polymaker-coupons-asa-ready/orca-preview.png`
• Review G-code: `print/gcode-review/polymaker-coupons-asa-ready/plate_1.gcode`
• Orca estimate: 4 h 15 m 32 s total, 43.48 g ASA.
• Settings: Polymaker ASA 260 C / 100 C, 0.20 mm layer height, 4 walls, 5 top/bottom layers, 25

Plate 2 - Internal Hardware Batch

Single-right Arducam:

• `femto_mount.stl`
• `arducam_mount.stl`
• `mic_rail.stl`
• `led_diffuser.stl`
• `cable_backbone.stl`
• `splice_plate.stl` contains two physical splice plates.

Symmetric dual Arducam:

• `femto_mount.stl`
• `arducam_mount.stl` x2
• `mic_rail.stl`
• `led_diffuser.stl`
• `cable_backbone.stl`
• `splice_plate.stl` contains two physical splice plates.

Approval gate: test the Femto cradle, Arducam mount, and cable clips against the real hardware before final shell assembly.

Current symmetric dual-Arducam internals review slice:

• Project: `print/3mf-current/approval-symmetric/02_internals_dual_arducam_ASA_READY.3mf`
• Preview: `print/gcode-review/symmetric-internals-asa-ready/orca-gui-preview-final.png`
• Review G-code: `print/gcode-review/symmetric-internals-asa-ready/plate_1.gcode`
• Current G-code footer estimate with conservative acceleration: about 12 h 21 min and 116 g ASA.
• Line-type preview includes brim, support, and support interface.

Short staged validation option:

• First one-part file: `print/gcode-review/single-arducam-mount-asa-ready/02A_ARDUCAM_MOUNT_ASA.gcode`
• Reference project: `print/gcode-review/single-arducam-mount-asa-ready/02A_ARDUCAM_MOUNT_ASA.3mf`
• Orca estimate: 31 m 37 s, 5.20 g ASA.
• Settings: Polymaker ASA 260 C / 100 C, 0.20 mm layer height, 4 walls, 5 top/bottom layers, 25
• Use this before the full 12-hour internals batch if the printer is still being tuned.

Plates 3-6 - Shell Halves

Print one large shell half per plate:

• `shell_front_L.stl`
• `shell_front_R.stl`
• `shell_rear_L.stl`
• `shell_rear_R.stl`

Approval gate: do not print these as final parts until the monitor footprint/cable exit, Femto thread location, and Arducam mount pitch are verified.

Current symmetric shell orientation review:

• Matrix report: `print/gcode-review/symmetric-shell-all-orientation-tests/README.md`
• Default orientations are rejected: each shell generates excessive support/time.
• Best supported candidates:
• Plate 3, `shell_front_L`: rotate X +90, about 18 h 38 m and 201 g ASA.
• Plate 4, `shell_front_R`: rotate X +90, about 10 h 56 m and 117 g ASA.
• Plate 5, `shell_rear_L`: rotate X -90, about 19 h 58 m and 217 g ASA.
• Plate 6, `shell_rear_R`: rotate X -90 with build-plate support, about 10 h 55 m and 116 g ASA.
• Total supported shell estimate: about 60 h 27 m and 651 g ASA.
• Decision: shell halves are now slicer-feasible, but still not final-print approved until the physical gates below pass and the candidate G-code is visually reviewed in OrcaSlicer Preview mode.

Plate 7 - Rear K11 Pod

These can be batched if OrcaSlicer support/orientation looks clean:

• `pod_top.stl`
• `pod_bottom.stl`
• `pod_compute_sled.stl`
• `pod_vesa_plate.stl`

Approval gate: confirm K11 orientation with ports toward the rear and bottom fan facing the pod intake slots.

The pod CAD now includes a rear K11 service window, matching VESA-plate window, and right-side USB/service slot. Use the side slot for a panel-mount USB extension or Bluetooth/Sony adapter pigtail if the rear will be blocked by a wall mount.

Current pod slicing review:

• Report: `print/gcode-review/symmetric-pod-orientation-tests/README.md`
• Default pod batch is rejected: `print/gcode-review/symmetric-pod-asa-ready/plate_1.gcode` estimated about 3d 23h 46m and 976 g ASA.
• Split pod jobs are in `print/gcode-review/symmetric-pod-split-jobs/`: top ~21h17m / 214g, bottom ~21h6m / 211g, compute sled ~6h2m / 61g, VESA plate ~3h28m / 36g.
• Print-oriented light review exists at `print/gcode-review/symmetric-pod-print-oriented-light/plate_1.gcode`, using `exports/approval-symmetric-print-oriented/` and `print/settings/lume_pod_asa_process.json`; estimate is about 2d 3h 56m and 521 g ASA.
• `pod_compute_sled` and `pod_vesa_plate` are review candidates.
• `pod_top` and `pod_bottom` are slicer-feasible only with the print-oriented light path, but not final-print approved. A single 52-hour pod batch is high risk; split the pod jobs or reduce pod shell mass before committing ASA.

Clean Review Queue

Current symmetric review queue folder:

`print/gcode-review/CURRENT_SYMMETRIC_REVIEW_QUEUE_2026-04-30/`

Use this folder for review so scratch, superseded, and rejected slices do not
get mixed into the workflow.

OrcaSlicer Baseline

• Material: ASA.
• Layer height: 0.20 mm.
• Walls: 4 perimeters.
• Top/bottom: 5 layers.
• Infill: 25
• Adhesion: brim for shells and pod halves.
• Supports: inspect manually; keep supports out of camera windows, cable feedthroughs, and the top monitor cradle where possible.

Still Needed Before Final Print

• ZHAOCAILIN monitor: total case width/depth/thickness and exact mini HDMI/USB-C exit side.
• ZHAOCAILIN monitor orientation: public listing gives about `305 x 80 x 60 mm`, but the current CAD uses the `305 x 80 mm` face footprint with a slim top-cradle render thickness until we approve whether the cased screen is flat, upright, or angled on top.
• Display retention: decide clamp/screw/VHB strategy and add strain relief for mini HDMI plus USB-C.
• Femto Mega: bottom 1/4-20 thread location relative to the front face and centerline.
• Arducam IMX586: metal case hole pitch, screw size, lens center, and USB-C cable bend radius.
• K11: final pod orientation and cable exit path.
• USB/power architecture: decide whether Femto runs USB, Ethernet/PoE, or DC + USB data, then reserve K11 ports and cable exits.
• Service access: confirm access to K11 power, power input, rear ports, and any Femto connectors after the pod is closed.
• Hardware BOM: M3 inserts/screws, Arducam screws, 1/4-20 Femto screw, VESA screws, rubber feet/grommets, and cable clamps.
• Thermal validation: run a powered pod temperature test before enclosed/semi-outdoor use.
