Step 06b.10 — Partially loosen the A/B joints and the front idlers¶
Step 36 of 42 · Chapter 06 — Z axis (and Chapter 06b — Gantry squaring)
Parts: none.
Do: Ease every circled bolt just enough to slide by hand: each A/B drive, both clamp pairs and the four rear-beam M5×10; each front idler, both clamp pairs. Voron warns: "Don't overdo the belt clamps!" Voron steps 8.2 and 8.3.
Check
All six printed assemblies can be nudged along their extrusions by hand. Every Z belt end is still gripped, top and bottom.
What you're looking at
Two A/B drives, two front idlers. On each, the top M5×16 pair through the upper clip and the bottom M3×30 + M5×30 under the bearing block clamp a Z belt. Each drive also has two M5×10 above and two below, into the rear beam.
Caution
This corner hangs from its Z belt. The top M5×16 clamp its second end, the bottom M3×30 / M5×30 its first. One corner at a time, about a turn. Voron: "Where there are Z belt clamps, ensure that you do not loosen the bolts to the point of the Z-belts releasing. Only loosen enough to allow for adjustments."
