I checked the Y-Axis Rail but not the others. I’ll do that tonight and report back.
Like I said, maybe the Rail Spacers are too thick? What are the dimensions of the Spacers?
Also, how much of a gap should there be between the Bottom Corner and Top Corner parts when they are assembled with rails and spacers but not tightened down? The Top part doesn’t sit down on top of the Bottom part, intentionally I believe so that they can clamp the rails, but how much of a gap should there be?
