[Manual] Z drive assembly doesn't mention seating set screws on motor shaft

[loopj]

Hey folks, absolutely love the manual but wanted to share something I missed on my initial build which could be an opportunity to improve it even further.

For the extruder and belt drive assembly there is a note that says:

Make sure the set screw in the drive pinion is seated on the flat of the motor shaft.

I think it would be great to say the same thing on page 38 for attaching the pulley to the Z drive shafts.

I think this edit resolves the suggestion. let me know if you meant something different! just in case it does resolve it as is, here is a updated version of the page plus a higher rez of just the edited assembly for the convenience of the Manual team!
