Parts:
- the gantry · already on the bench
- long zip tie ×4, only without the rubber stoppers · consumable
Do:
- Lower until each Z block seats on its lower joint, nudging carriages until the bores line up.
- No rail stoppers? First zip-tie each corner up over the top frame rail.
- Let go one at a time.
Check
The gantry rests on all four joints with nobody holding it. It does not rock, and no corner is visibly lower than the others.
Helper Lowers the other side in step with you and lets go only when you say so.
What you're looking at
Each Z bearing block comes down onto the domed top of its lower joint. The last millimetre should be gravity, not force: if a block will not seat, slide that carriage along its rail rather than levering the gantry.
