I'm looking at the BOM and the CAD models, and I'm confused about the number and type of screws necessary here.
On the exploded X motor end diagram, there are two socket head cap screws (ANSI B18.3 - 6-40 UNF - 0.5) that hold on the nut cap. What do these thread into? You seem to use sheet metal screws for attaching the X inner slide, but not for the nut caps.
Thanks so much in advance, and for your great design.
