Hi, the wheels on the opposite side of the rail with the eccentric nuts were always supposed to stay on, they were used as a sort of preload adjustment. This mounting setup was supposed to be simple quick and an improvement over the 4 wheel setup it was never meant to be the perfect solution.
The hole next to the drilled one depends on which bed you have, there seems to have been 2 versions that i know of with either the wheel holes aligned on both sides or offset. Mine originally were offset so that was what i used for the original design.
I did run it for over a year on 2 machines though with no real issues. I am just about to upload a different version of a Y Axis rail setup i use now.
