Batch B07 — Electronics bay + lighting

One page per step

Read this chapter one step per page — big pictures, prev/next, and the same tick marks. This page is the whole chapter in one scroll.

Revali watching a first layer
The bay parts. Nothing here holds a bearing, so Gate A is enough. A rare, relaxing plate.

Time: 16.0 h (2 plates) — PrusaSlicer 2.9.6 estimates.

Sessions: 2 plate starts (~5 min hands-on each, 7.9 / 8.1 h unattended) + ~15 min inspect and bin.

Prerequisites: Gate A passed (Step B00.5). Nothing here has a bearing seat or rail fit. It does not depend on B01–B06 (the electronics bay is independent of the mechanical gantry); its heat-set bosses get their inserts on kit day, in Ch 09.

PSU_stabilizer_50mm (verify)

LDO Build Notes say "PAGE 169 SKIP — the kit does not use a support bracket," which most likely refers to this part. It is 4 g — print it, fit only if it's actually needed.

Do not print: raspberrypi_bracket.stl, beefy_raspberry_bracket.stl, rs25_psu_bracket.stl (Leviathan carries the Pi, no 5 V PSU in this kit); the Leviathan bracket set or the bed WAGO mount (both supplied printed).

Hardware: none.

Read first

  • Checkpoint after B07: COB mount halves flat on the reference and closing flush on their 2× M3×6 FHCS. The Wago mount's heat-set bosses get their inserts on kit day (Ch 09), not here.
  • Most commonly reprinted here: cob_light_strip_mount_100mm — warps at the ends, check flatness on glass.
  • COB counts are LDO's own for a 2.4-350: 6× 100 mm + 2× 50 mm. Each STL contains a 2-piece assembly joined with 2× M3 heat-sets + 2× M3×6 FHCS — the heaviest single group of "small" parts in the build (127 g on P2 alone).

Step B07.1 — Filament prep

Do: Galaxy Black, spool #2 after B06. The ledger has 652 g on it here, 550 g after P1 and 426 g after P2, so no runout in this batch. Sheet per 00-slicer-setup § Print sheet.

check Check

Clean purge; ≥226 g on spool #2 for the two plates.

Step B07.2 — Load plate B07-P1

Sorting diagram, drawn from the committed project: every part numbered and filled in the colour of its bin, bin id on the part; the legend reads # · STL · bin (chapter · steps). Sort at Step B07.7.

Do: Open slicer/plates/B07-P1.3mf with File → Open Project. The arrangement, brims and overrides are already in it. Confirm it loaded as described rather than rebuilding it. Parts: wago_221-415_mount_3by5 · lrs_200_psu_bracket_x2 ×2 · PSU_stabilizer_50mm · usb_adapter_mount · usb_adapter_mount_partial_cover ×1 (ground-lug mount, est.) · pcb_din_clip_x3 ×3 · handlebar_spacer_x4 ×4 · power_inlet_IECGS_1mm · 8 files, 14 objects — 7.9 h, 102 g (PrusaSlicer 2.9.6 estimate) · 3 mm brim on wago_221-415_mount_3by5 and power_inlet_IECGS_1mm (the long-flat list), already in the project.

check Check

No face re-orientation, all flat as shipped; the preview shows a brim outline on the Wago mount and the inlet.

Helper: Counts the parts on the sorting diagram and checks the total against the object count.

Step B07.3 — Print plate B07-P1

Do: Print with standing overrides.

check Check

Before start, Settings → Chamber Filtration reads Adv. Filtration. Clean first layer across the inlet's full 118 mm; no corner lift.

plate started; nothing to do until it finishes.

Step B07.4 — Load plate B07-P2

Sorting diagram, drawn from the committed project: every part numbered and filled in the colour of its bin, bin id on the part; the legend reads # · STL · bin (chapter · steps). Sort at Step B07.7.

Do: Open slicer/plates/B07-P2.3mf with File → Open Project. The arrangement, brims and overrides are already in it. Confirm it loaded as described rather than rebuilding it. Parts: cob_light_strip_mount_100mm ×6 · cob_light_strip_mount_50mm ×2, eight mounts total, each a 2-piece assembly — 8.1 h, 124 g (PrusaSlicer 2.9.6 estimate) · 3 mm brim on the six 100 mm mounts, already in the project (long-flat brim list), none on the two 50 mm mounts.

check Check

Brim outline on the six 100 mm mounts only; eight mounts on the plate and nothing else.

Helper: Names the bin colour of each part on the sorting diagram while you open the project.

Step B07.5 — Print plate B07-P2

Do: Print with standing overrides.

check Check

Watch for end-lift on the 100 mm mounts partway through: this is the batch's known warp risk.

Step B07.6 — Inspect

Do:

  1. Lay each COB mount pair on the granite reference and dry-fit the two halves by hand.
  2. Check the Wago mount's heat-set bosses are crisp and round.

check Check

No rocking on the flat reference; halves close flush; bosses undamaged.

pause Good stopping point · ~15 min since the last one

every mount checked on the reference, brims snapped off, nothing assembled.

Step B07.7 — Sort into bins

Do: Sort off each plate diagram; the printed bin id names the bin. Mark plate id and date on a hidden face. Labels: bin-labels sheet. The inlet lives in 09-bay, only borrowed for the skirt-ring dry-fit at Step 11.1.

B07-P1

08-CW2 — Clockwork 2 extruder, toolboard + USB covers usb_adapter_mount_partial_cover
09-bay — Electronics bay: inlet, WAGO, PSU, DIN clips wago_221-415_mount_3by5, lrs_200_psu_bracket ×2, PSU_stabilizer_50mm, pcb_din_clip ×3, power_inlet_IECGS_1mm

B07-P2

bin parts off this plate
10-lights — COB light-strip mounts cob_light_strip_mount_100mm ×6, cob_light_strip_mount_50mm ×2

check Check

COB mounts counted, six 100 mm and two 50 mm, in 10-lights; power_inlet_IECGS_1mm in 09-bay.

Helper: Reads each bin label aloud and checks the count against the diagram.

pause Good stopping point · ~10 min since the last one

both plates sorted into 08-CW2, 09-bay, 10-lights and 11-finish, the spare usb_adapter_mount in spare-alt. No heat-set inserts yet; Ch 09 sets them on kit day.

Checkpoint B07

  • COB mount halves close flush on 2× M3×6 FHCS, all eight assemblies
  • COB mounts checked flat on granite reference — no rocking
  • Wago mount heat-set bosses crisp (inserts go in at Ch 09)
  • PSU_stabilizer_50mm fit decision made (verify against actual PSU)
  • power_inlet_IECGS_1mm off B07-P1 flat, brim snapped off cleanly, binned for Ch 09
Revali passing a gate
Batch B07 printed: plates 11 to 12 of 22, 100.3 of 157.0 h. 2 gummy worms.

Common mistakes

  • Printing raspberrypi_bracket or rs25_psu_bracket out of habit from other Voron builds — this kit needs neither.
  • Skipping the flat-reference check on COB mounts and only discovering warp at final assembly.

Next

Assembly: Electronics (p.148–173), Controller (p.174–179), Wiring (p.180–211) — on kit day, out of bins 09-bay and 10-lights; the USB adapter cover waits in 08-CW2 for Ch 08 and the handlebar spacers in 11-finish. Printing: straight on to B08 — Skirts and front modules.
