I’ve noticed I have one bearing in my middle assembly that doesn’t contact the rail (see pics). details of the build / things I’ve checked so far:
- printed parts purchased from Ryan
- conduit measures ~23.3mm; have rotated, but no contact made
- machine size ~ 30"x 30" x 3.5"
- diagonal measurements within ~1/16"
- all tension bolts are loose; perhaps there is some combination I can tighten to adjust this?
- square as far as i can measure
