Parts:
-
[a]_z_chain_retainer_bracket×1 · bin 10-chains - M3×12 SHCS ×2 · Fasteners, Tools & Misc box
- M3×10 FHCS ×2 · Fasteners, Tools & Misc box
- zip ties, 2 · consumable
Do:
- Bolt the bracket to the A drive with two M3×12 SHCS and the chain's upper end into its inserts with two M3×10 FHCS.
- Guide the wire bundle behind the Z belt and over the A drive, zip-tied.
Check
Move the gantry through full Z travel. The bundle never touches the Z belt and the chain's top end never twists.
What you're looking at
The blue [a]_z_chain_retainer_bracket bolts to the A drive at the top of the loop and carries the chain's moving end up and down with the gantry. The manual page also fixes the wire path: behind the Z belt and over the drive.
Good stopping point · ~35 min since the last one
X, Y and Z chains all mounted at both ends, A/B motor cables bundled, retainer bracket on the A drive. Chains are empty and latched. Do not part-fill a chain and walk away — the next segment fills all three in one go.
