Does it bind when the leadscrew half nut is disengaged if the saddle is tight and the and the gears are working hard to move it i have had trouble with the gears doing similar. Those gears don’t like hard work they have to easily turn without any straining
This might be a place to start looking. Or what about a drop of low strength locktite on the screw to stop it undoing Looks like The gear is rubbing on the washer turning it and undoing the screw does it undo when running the mill in reverse turning that gear clock wise .
