Assembly note needed

[bdbell]

A note should be added to either the assembly guide or the build page that mentions that loctite on the motor grub screws should be left off until the pulley is fully aligned with the belt path. People have reported issues with putting loctite on early then not being able to move the pulley since the grub screws are fixed. (Admittedly this shouldn't happen with 242, but people are people)
