Top servo mount, bearing retainer cap screws
Anyone have their top main shaft bearing retaining screws interfere with the mast collar? Built the main frame set this evening. The M2.5x6 screws which are used to secure the outer race of the bearing to the top servo mount/bearing plate gave me an interference with the mast collar. Didn't know if an update was done to alleviate this? I removed the screws and sanded down the heads to clear. Still, the M2x6 screw which is used to secure the mast collar has it's head slightly protruding from the mast collar. It rubbed the bearing retaining screw heads too. Not a big deal, but a pretty basic flaw. Anyone else?
What was the tiny grub screw for in the package containing the metal bearing plate? It included the bearing, and two M2.5x6 screws for securing the bearing, and a grub screw. Didn't note the size. I thought maybe it was intended to secure the outer race instead of the M2.5x6 cap screws, but saw no mention of it in the instructions or a tapped hole for locating it for such a purpose. Anyone?

Top bearing plate doesn't need screw to hold bearing. Collar will do that. The screw is needed only when you use the beating plate for the middle bearing.

Thanks. I thought of that too. However, the bearing fit is definitely on the loose side. I may remove the screws and apply some Loctite compound to the plate bore to secure the outer race from spinning. Mine is a loose fit.

Yeah. I guess I got lucky. Mine are tight, both the CNC one I'm using and the plastic one I used before swapped out for the CNC one.
