Step 05.18 — Fit the second Y backer¶
Step 18 of 48 · Chapter 05 — Gantry: X and Y axes, XY joints, X carriage, titanium backers
Parts:
- titanium Y backer ×1 · Ti backer set
- M3×8 FHCS ×10 · Ti backer set
- M3 roll-in T-nut ×10 · Fasteners, Tools & Misc box
Do: Repeat on the second C extrusion, again on the face opposite its rail. Lay the two finished Y assemblies side by side and confirm they match: rails facing the same way, backers facing the same way.
Check
Both backers on the rail-opposite face, both flat. Their cable-chain pilot holes end up on the same side of the machine.
What you're looking at
The second Y extrusion, same treatment on its rail-opposite face. The first render shows one Y extrusion from underneath, rail face and backer face both in frame. The second shows both Y beams in place: rails underneath on both, backers on top on both.
Tip
The CAD C extrusion is 350 mm with a 300 mm rail (250 machine); yours is the 350-kit C with a 400 mm rail.
Good stopping point · ~35 min since the last one
both titanium Y backers screwed down flat on the rail-opposite face. Check nothing is cammed out before you stop.
