how tight should the screws be that pitch the bearings. Like for the middle assembly and the guides for the belts. Should they be at the point where they spin but don’t continue to spin on their own or should it be where you can flick it and they spin fast.

They should be tight enough with no tension. If you have bearings that do not touch take it apart and try again, carefully going step by step following the instructions. Or use it for a bit to break it in and then rebuild. This happens on some people’s own prints.

Ok I’m guessing that means spins easily. Like in the video

Spinning freely means the bearing is not lubricated.
