Shout out to yelobird. Let me try to add on for those that are slightly dull like myself.
I had to remove the metal ring assembly and opto board entirely in order to reach the mini “set screws” with my multi hex wrench tool.
If you also have clearance issue trying to reach the tiny Allen screws, Use pliers, forceps to hold long hex nuts that run down into the base of the topper and unscrew the metal ring.
I believe He’s a bit too indirect in his assessment; I believe the problem was absolutely that these tiny screws connecting the roller to the pivot rod were either A) too loose, B) not a single one against the flat side or. C) both.
