Step 06b.12 — Retighten everything except the X/Y joints¶
Step 38 of 42 · Chapter 06 — Z axis (and Chapter 06b — Gantry squaring)

Parts: none.
Do: Tighten every extrusion bolt you loosened at 06b.9–06b.10 except the three joint-to-beam bolts at each X/Y joint, left for de-racking. Z belt clamps included. Re-run the flush-and-bolt-slides check at all four corners. Voron step 10.
Check
A/B joints and front idlers tight, top and bottom; the M5×40 still starts by hand at all four Z joints; the four-point measurement unchanged.
What you're looking at
Everything you loosened gets tightened again except the XY joints. Those stay free because the next step pushes the X extrusion hard against the two drive units and tightens the joints in that position.
