Step B00.5 — Inspect: Gate A (the cube, no kit needed)¶
Step 7 of 9 with a helper · Batch B00 — Calibration & jigs
(no image — see text)
Do:
- Once cool, remove the plate and run Gate A with calipers at mid-height.
- Cube X/Y 30.00 mm ±0.15 mm, Z 30.00 mm ±0.10 mm, first-layer-vs-mid-height X delta ≤0.15 mm, corner snap no delamination.
- Log all four numbers.
Check
All four pass; any failure means adjusting extrusion multiplier, never negative XY compensation, then reprinting this plate before B02 or B07.
Helper Reads each caliper number back aloud and types it into the Gate A calculator.
Gate A — the 30 mm cube — the calculator needs JavaScript; the limits are in the table on this page.
The 30 mm cube is a ruler for the printer. X and Y say whether walls come out the size the CAD drew, which every bearing bore in the machine depends on; Z says whether the first layer is squished right; the corner snap says whether the layers weld. Every later plate inherits these four numbers.
Tip
corner snap means grip a corner in pliers and bend it off. A pass tears across the layers; a peel along one layer line is a fail.
Good stopping point · ~15 min since the last one
Gate A is measured and written down; B02 and B07 are released. The Gate B coupons (Heatset_Practice, one MGN12_rail_guide, z_drive_retainer_a) are not tested yet — do not bin them with the jigs.
