Batch B11 — Bay ducting (PETG V0)

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.

Ducts carry wires, not load. Same printer, different spool, gentler rules.

Time: 25.0 h (5 plates) — PrusaSlicer 2.9.6 estimates: 11.9 h before kit (B11-P1 to P3, 173 g), 13.1 h after the kit-day measurements (B11-P4 and B11-P5, 175 g). 348 g of Jet Black PETG V0 in all. Not part of the 157.0 h ASA run, and none of its numbers are in the run's totals.

Sessions: 5 plate starts (~5 min hands-on each, all day plates), ~10 min for the coupon test, ~15 min to inspect and bin; ~35 min of bay measuring on kit day, before P4 and P5, and ~15 min for the A/B lead check after Checkpoint 06.

Prerequisites: nothing from the ASA run. No part here holds a bearing or takes a press fit, so neither Gate A nor Gate B applies. Needs one 1 kg spool of Prusament PETG V0 Jet Black (not yet bought) and the textured sheet. P4 and P5 print right after kit day, as soon as the kit-day bay measurements (B11.10, B11.11) are done, and must be binned before Ch 09 Step 09.6 lays the DC loop. The A/B motor-lead check (B11.9) does not gate them: it needs the gantry hung, so it runs after Checkpoint 06, and a short lead gets a longer replacement before Ch 10. Layout v3 stands either way.

What this batch builds. Layout v3 replaces LDO's five PVC wire ducts in the electronics bay with two printed conduits, made from MyStoopidStuff's remix of RyanDam's Cable Management Duct. The DC conduit is one loop: curved 90° corners, two T-junctions, a 45° S-jog up to the Z-chain notch, and a middle run narrowed to 22 mm so it fits between the Leviathan and the PSU. The AC conduit is MSS's wire box at its original size by the WAGO bus, two re-radiused 90° curves down to a 34 mm run over the bed-lead hole, a T behind the SSR, and a divider fin at the PSU terminals. The closest AC-to-DC approach is 12.0 mm on the layout (verify on bench). Fitting them is Ch 09's and Ch 10's job; this page only prints them. Design record: review/2026-09-23-bay-mods/layout-v3/layout-v3.md.

Printed parts

Every part is Jet Black PETG V0 ("Black" below). g ea is each piece sliced alone with slicer/bay-ducts-petg.ini, purge line included, so the column does not sum to a plate line.

Layout v3 drawn on LDO's Rev D placement photo, front of the printer at the top. Apparent millimetres, ±6 % absolute and ±1.5 mm on local gaps: every position is (verify on bench). Photo: LDO Motors; drawing: this repo.

Which piece goes where: the two stock 154s are the front run; the three corners are front-left (the mirrored one), front-right and rear-right; the 45° pair is the S-jog; the 58s are L1, R1 and rear-lower, the 130 is L2, the 70 is R2; the three 10 mm pieces are the DC rear-upper run, the SSR run's right end and the stub up into the wire box's port. Positions and clearances: review/2026-09-23-bay-mods/layout-v3/layout-v3.md.

Options, not plated:

• Orange endcaps. The two CMD_Remix-V3_DUCT-1M_ENDCAP can be printed in the spare Prusament ASA Prusa Orange instead, as a visual mark on the AC conduit's ends. Load the STL on its own with slicer/voron-coreone-asa.ini and the smooth sheet. No plate, no ledger line; the black pair on B11-P3 is the default.
• WARNING lid. MSS's lettered CMD_Remix-V3_DUCT-1V_WIRE_BOX_LID_WARNING + inlay (Printables 505838) is a two-colour body and waits for the INDX. B11 prints the plain CMD_V2_6B_WIRE_BOX_COVER.
• Fallback middle run. If the Leviathan-to-PSU gap measures under 25 mm, skip B11-P5 and print stock CMD_V3_1H_T_REG + cover in place of each V3L_T_REG_N, plus one CMD_V3_1H_82mm_DUCT + cover, and keep LDO's PVC middle duct. Those four files are vendored in mss/502306/ but on no plate. Their bodies go to bin 09-ducts-DC and their covers to 11-lids-DC, whose labels already list them as the fallback.

Hardware: none to print. Mounting hardware and tape belong to Ch 09.

Read first

• Not Voron spec. The ducts carry no load, so B11 has its own bundle, slicer/bay-ducts-petg.ini: system filament Prusament PETG V0 @COREONE HF0.4, 0.20 mm layers, 3 perimeters, 4 top and 4 bottom, 20 % grid infill, no supports. Printer settings and the cold start G-code are the ASA run's. Grid, not gyroid: gyroid infill curls with PETG on this printer. Every key: slicer/OVERRIDES.md § Bay-duct bundle.
• Textured sheet. Prusa does not recommend PETG V0 on smooth PEI: it bonds hard enough to damage the sheet, and that damage is not covered by warranty. Swap back to the smooth sheet before the next ASA plate.
• AFS flaps. The bundle's filament start G-code sends M106 P3 S160 and its end G-code M106 P3 R, so the bypass flaps lift for PETG with Chamber Filtration left on Adv. Filtration. Print from Connect or USB, not OctoPrint: the fixed P3 target makes M141 log an error OctoPrint would halt on.
• Arrangement provisional, GUI QC pending. All five plates were packed by slicer/nest.py at a 6 mm gap and sliced from the CLI; none has been opened, arranged and re-saved in PrusaSlicer yet. Before each first print: Arrange Current Bed (6 mm, rotations on), save over slicer/plates/B11-Pn.3mf, then python3 slicer/build_plates.py --from-3mf B11-Pn and python3 slicer/check_docs.py.
• Two groups. P1 to P3 need nothing measured and can print whenever the printer is free. P4 holds the custom lengths and P5 the narrowed middle run; both wait for the kit-day bay measurements, and P5 also waits for the coupon test. The A/B lead check after Checkpoint 06 only decides whether a longer replacement lead is needed.
• Every part is Jet Black. Nothing here is dimension-critical beyond the lid snap, which the coupon tests.

Before kit

Step B11.1 — Filament and sheet prep

Do: Load the Prusament PETG V0 Jet Black spool, V1 in the ledger. A fresh sealed spool goes straight in; an opened one dries at 55 °C for 6 h. Fit the textured sheet.

Check

Textured sheet on, clean purge, and at least 348 g on the spool for the whole batch.

Sheet

Prusa does not recommend PETG V0 on smooth PEI. It can bond hard enough to tear the coating, and the damage is not covered by warranty. Keep the smooth sheet for ASA. src

Step B11.2 — Pre-print checks

Do: Door closed, Chamber Filtration left on Adv. Filtration. Watch the rear bypass flaps once the plate starts.

Check

The flaps lift within the first minutes and the chamber settles near 35 °C (verify on bench).

Tip

If the flaps stay shut, set Chamber Filtration to None by hand for this plate; the chamber fans then lift them. Set Adv. Filtration again when it ends.

Step B11.3 — Load and print plate B11-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 B11.8.

Do: Open slicer/plates/B11-P1.3mf with File → Open Project and print it on its own, first. It is the lid-snap test for the narrowed middle run. Parts: V3L_COUPON_22N_DUCT · V3L_COUPON_22N_DUCT_COVER · 2 files, 2 objects — 0.4 h, 4 g (PrusaSlicer 2.9.6 estimate) · no brim.

Check

Preview shows the bay-ducts PETG V0 bundle, the duct base down and the lid flat, no supports.

GUI QC pending

this arrangement came from nest.py. Before the first print, run Arrange Current Bed, save over the 3MF, then build_plates.py --from-3mf B11-P1 and check_docs.py.

Step B11.4 — Test the coupon's lid snap

What you're looking at: The coupon is a 22 mm slice of the narrowed middle run. Its walls, tines and lid rail are the stock geometry; only the floor and lid are 2.4 mm narrower.

Do: Snap the lid on and off five times, then shake the coupon lid down.

Check

The lid clicks home each time and stays on when shaken. Any crack or loose lid means no B11-P5.

Good stopping point · ~10 min since the last one

coupon tested and back in bin 09-ducts-DC. The bundle-fill test waits for the harness on kit day.

Step B11.5 — Load and print plate B11-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 B11.8.

Do: Open slicer/plates/B11-P2.3mf with File → Open Project. This is the DC conduit's front run and its three corners. Parts: CMD_V3_1H_154mm_DUCT ×2 · CMD_V2_6B_154mm_DUCT_COVER ×2 · CMD_V3_1H_90DEG ×2 · CMD_V2_6B_90DEG_COVER ×2 · V2L_90DEG_MIRROR · V2L_90DEG_COVER_MIRROR · 6 files, 10 objects — 6.9 h, 96 g (PrusaSlicer 2.9.6 estimate) · no brim.

Check

Every duct body base down, every lid flat; the two 154 mm ducts lie clear of the bed edge.

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 B11.8.

Do: Open slicer/plates/B11-P3.3mf with File → Open Project. This is the AC conduit, the strip fin and the DC S-jog. Parts: V3L_WIRE_BOX_PORT · CMD_V2_6B_WIRE_BOX_COVER · V3L_90DEG_R15 ×2 · V3L_90DEG_R15_COVER ×2 · CMD_V3_1H_T_SHORT · CMD_V2_6B_T_SHORT_COVER · CMD_Remix-V3_DUCT-1M_ENDCAP ×2 · V2L_STRIP_FIN · CMD_Remix-V3_DUCT-2B_45deg ×2 · CMD_Remix-V3_DUCT-2B_45deg_LID ×2 · 10 files, 15 objects — 4.6 h, 73 g (PrusaSlicer 2.9.6 estimate) · no brim.

Step B11.7 — Inspect the before-kit plates

Do: Snap every lid onto its duct once. Check each tine row for strings and each base for elephant foot.

Check

Every lid seats along its full length; no tine is fused to its neighbour; bases are flat.

Good stopping point · ~10 min since the last one

before-kit parts inspected and bagged by plate.

Source: print plan §5.2 — checkpoint after each batch

Step B11.8 — Sort into bins

Do: Sort off the plate diagrams: number to legend, colour to bin, bin id on the part. Mark plate id and date on a hidden face. Labels. Bodies to 09-ducts-DC or 09-ducts-AC; lids to 10-lids-AC or 11-lids-DC; fin to 10-lids-AC.

Check

9 pieces in 09-ducts-DC, 6 in 09-ducts-AC, 5 in 10-lids-AC with the strip fin, 7 in 11-lids-DC.

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

Before the next ASA plate

smooth sheet back on, and Settings → Chamber Filtration reads Adv. Filtration. On None the AFS blower never runs and ASA vents unfiltered.

Good stopping point · ~10 min since the last one

the before-kit half of B11 is binned. Swap the smooth sheet back on and set Adv. Filtration if an ASA plate is next.

After the kit-day measurements

Step B11.9 — Confirm the A/B motor leads after Checkpoint 06

What you're looking at: Layout v3 routes the A and B leads through the notch, right run and middle run: about 195 mm more for A, 129 mm for B, than LDO's route. The leads reach the deck only once the gantry hangs.

Do: After Checkpoint 06, printer upright, gantry low:

1. Run each lead along the extrusion between the drives, then down the Z chain's path to the deck notch. Tape-mark it there.
2. Measure mark to plug tip, minus B11.10's LDO length.

Check

A has at least 215 mm spare and B at least 150 mm. Either way, print P4 and P5 on schedule.

B11 confirmation — A and B motor lead spare length — the calculator needs JavaScript; the limits are in the table on this page.

If a lead is short

make a longer replacement lead — a 4-pin JST-XH cable, same wire gauge as the stock lead (verify on bench) — rather than dropping back to layout v1; Ch 10 fits it with the motor. P4 and P5 print now regardless.

Tip

The Z chain hangs at the rear from the A drive down to its guide by the deck, as p.201 shows. Hold the kit's chain there and follow it (verify on bench).

Good stopping point · ~15 min since the last one

both leads measured after Checkpoint 06 and logged; leads hang loose again, tape marks off, nothing fastened. A short lead means making a longer replacement before Ch 10; P4 and P5 are unaffected.

Step B11.10 — Measure the gaps the custom pieces fill

Do: Kit day, deck panel loose:

1. Dry-lay the rails, PSU, SSR, Leviathan and P2 and P3 pieces per the overlay.
2. Caliper the rows below.
3. String LDO's duct route from the notch to HV-STEPPER-1 and HV-STEPPER-0; log both.

Check

Every row entered, both string lengths logged. The gap row decides P5, the SSR row the stub, regenerated at B11.11 only from 112 mm.

B11 bay gaps — what P4 and P5 are cut to — the calculator needs JavaScript; the limits are in the table on this page.

Helper: Reads each caliper number back aloud and writes it into the log.

Tip

The bed TH, probe, filter-fan leads and Bed L route in Ch 10; the probe and filter fan aren't built until Ch 09 and Ch 11. Fit confirms then.

Good stopping point · ~20 min since the last one

the bay is dry-laid and measured; nothing is stuck down or fastened.

Step B11.11 — Regenerate a piece whose gap differs

What you're looking at: Every custom straight is a stock MSS duct with a slab cut out. Lengths come in 12 mm steps, 10, 22, 34 up to 154 mm, because each cut sits on a tine boundary. Only the stub changes with a bench gap.

Do:

1. Stub length: the 12 mm step at or below the SSR gap minus 90. Run the recipe only if that is 22 or more.
2. Make the three edits in its comments.
3. Run its last line.

Step B11.13 — Load and print plate B11-P5

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 B11.14.

Do: Print this plate only if the coupon passed and the gap measured 25 mm or more. Otherwise print the fallback listed under Options instead. Parts: V3L_154N_DUCT ×2 · V3L_154N_DUCT_COVER ×2 · V3L_T_REG_N ×2 · V3L_T_REG_N_COVER ×2 · 4 files, 8 objects — 6.8 h, 93 g (PrusaSlicer 2.9.6 estimate) · no brim.

Check

Both narrowed 154s and both narrowed Ts base down, lids flat.

Fallback

stock CMD_V3_1H_T_REG and CMD_V3_1H_82mm_DUCT are drawn base up. Load them with slicer/bay-ducts-petg.ini, place each on its wide flat base, and print their covers as they come.

Step B11.14 — Sort the after-kit plates into bins

Do: Snap each lid on once, then sort off the diagrams: bodies to 09-ducts-DC or 09-ducts-AC, lids to 10-lids-AC or 11-lids-DC.

B11-P4

bin	parts off this plate
09-ducts-DC — DC conduit + coupon, B11	V2L_58mm_DUCT ×3, V2L_130mm_DUCT, V2L_70mm_DUCT, V3L_10mm_DUCT
09-ducts-AC — AC conduit, B11	V3L_10mm_DUCT ×2, V3L_34mm_DUCT_HOLE
10-lids-AC — AC lids + strip fin, B11	V3L_10mm_DUCT_COVER ×2, V3L_34mm_DUCT_COVER
11-lids-DC — DC lids, B11	V2L_58mm_DUCT_COVER ×3, V2L_130mm_DUCT_COVER, V2L_70mm_DUCT_COVER, V3L_10mm_DUCT_COVER

B11-P5

11-lids-DC — DC lids, B11	CMD_V2_6B_T_REG_COVER ×2, CMD_V2_6B_82mm_DUCT_COVER

Check

P4 sorted 6, 3, 3 and 6 into 09-ducts-DC, 09-ducts-AC, 10-lids-AC and 11-lids-DC; P5 or the fallback into the DC two.

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

Before the next ASA plate

smooth sheet back on, and Settings → Chamber Filtration reads Adv. Filtration. On None the AFS blower never runs and ASA vents unfiltered.

Checkpoint B11

• Coupon lid snaps home and holds, tested before B11-P5
• A/B leads confirmed after Checkpoint 06; a longer replacement lead made before Ch 10 if either was short
• Leviathan-to-PSU gap measured: B11-P5 printed, or the fallback with LDO's PVC middle duct
• SSR-to-WAGO measured; the stub regenerated at B11.11 if the gap was 112 mm or more
• TH, probe, filter-fan and bed L leads confirmed against layout v3 in Ch 09/10, not on kit day
• Every lid snaps onto its duct; bodies in 09-ducts-DC and 09-ducts-AC, lids in 10-lids-AC with the strip fin and 11-lids-DC
• Smooth sheet back on the printer and Chamber Filtration on Adv. Filtration for any ASA plate
• GUI QC done on all five plates and check_docs.py green after the re-saves

Batch B11 printed: 5 plates, 25.0 h, outside the 157.0 h run. 5 gummy worms.

Common mistakes

• Printing PETG V0 on the smooth sheet. It can tear the coating; use the textured sheet.
• Printing B11-P5 before the coupon test and the gap measurement. Both can send it to the fallback.
• Slicing a regenerated piece with the ASA bundle. B11 uses slicer/bay-ducts-petg.ini only.
• Leaving Adv. Filtration to hold the flaps shut on a PETG plate printed without the B11 bundle.
• Starting the next ASA plate with Chamber Filtration still on None. The AFS blower never runs, so the styrene goes into the room.

Next

Ch 09 fits the conduits in place of LDO's PVC ducts, in its bay-ducting variant; Ch 10 lays the harness in them and fits the strip fin as it closes the AC lids.
