Step B11.9 — Confirm the A/B motor leads after Checkpoint 06¶
Step 9 of 14 · Batch B11 — Bay ducting (PETG V0)
(no image — see text)
Do: After Checkpoint 06, printer upright, gantry low:
- Run each lead along the extrusion between the drives, then down the Z chain's path to the deck notch. Tape-mark it there.
- 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.
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.
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.
