Step 05.31 — Bolt the left joint and fit its idler¶
Step 31 of 48 · Chapter 05 — Gantry: X and Y axes, XY joints, X carriage, titanium backers

Parts:
- M5×40 SHCS ×3 · Fasteners, Tools & Misc box
- GT2 20-tooth idler ×1 · Motion box
Do: Turn the joint over, thin plate up. Two M5×40 SHCS down through the plate into the remaining M5 nuts, tightened evenly and firm into steel. Then the 20T idler and its own M5×40 into plastic: snug only, must spin.
Check
Both joints complete: 4× M5×40 each, 2× F695 each, two spacers each, one 20T idler each, all bearing stacks and both idlers free.
What you're looking at
Both joints finished and identical in content: 4× M5×40, 2× F695 between two precision spacers, and one 20 T idler each. Everything meant to spin must still spin freely; drag here becomes belt noise once the belts go on.
Good stopping point · ~20 min since the last one
both XY joints built, bolted and idler-fitted, sitting loose on the bench. Do not slide them onto the X extrusion yet.
