Step B00.7 — Gate B, bore and inserts now, rail on kit day¶
Step 9 of 9 · Batch B00 — Calibration & jigs
(no image — see text)
Do:
- Open the GATE B bag and run Gate B.
- Caliper the
z_drive_retainer_a625-2RS pocket, then set seven KADRICK inserts. - Kit day: thumb a real 625-2RS into that pocket, then slide the
MGN12_rail_guideonto the real MGN12 rail.
Check
The pocket calipers 16.30 mm ±0.15 and all seven inserts sit flush. Bearing and rail rows sign off on kit day.
What you're looking at
A 625-2RS is the plain 16 mm bearing in every Z drive, and this pocket is the seat it presses into. The caliper now is standing in for that press: if the pocket is wrong, 22 h of Z-drive bodies would print wrong with it. Flush, un-bulged inserts mean the iron is right before any real part sees one. The adult sets the inserts; the helper never handles the iron.

Caution
A pocket outside 16.30 mm ±0.15 is the profile, not the part. Confirm shrinkage compensation is 0 %, then move extrusion multiplier 1 %, reprint the retainer and the cube, re-pass Gate A, and only then start B01. A bulging boss is technique, so practise rather than re-slice. The six MGN9 rails stay sealed until rail prep.
Good stopping point · ~15 min since the last one
Gate B's caliper and insert rows are measured and written down; B01 and B03–B06 are released. Put the retainer in bin 02-Z0 and keep the rail guide in 00-jigs for the kit-day rows.
