The pen rail must have 5mm machine screw threads cut into the holes on each side. I've talked about this before.

Put the 5x12mm machine screw into the motor mount and screw it into the end of the pen rail. Use the access hole in the mount to get your allen wrench in there.

Doesn't matter which way the mount goes. All of the sides are the same!
