Step 40 of 48 with a helper · Chapter 05 — Gantry: X and Y axes, XY joints, X carriage, titanium backers

Parts: none.
Do:
- Left joint: F695 stack upper, 20T idler lower. Right joint: 20T upper, F695 lower.
- Sight along the extrusion: left 20T level with right F695, left F695 level with right 20T. Spin all four.
Check
Left 20T level with right F695, left F695 level with right 20T; nothing binds; the MGN12 carriage still slides freely and is still taped.
Helper Spins each bearing stack and idler and calls out any that drags.
What you're looking at
The finished X axis, checked against the drawing. You are sighting for each belt's two corners at the same height: a corner a millimetre out of plane feeds the belt into the drive pulley at an angle and chews its edge.
Good stopping point · ~35 min since the last one
both XY joints bolted to the X extrusion top and bottom, cable bridge on, assembly checked against p.105. Still motors-down, the way it runs. The flip is the next step — do not attempt it alone.
