Alright, this will take some modeling (and trial and error) but I think I know what to do to adjust the Z-rails. I’m going to modify the top and/or bottom parts of the gantry (in my case, I only need to modify the bottom part) to add set screws that will allow the bearings on the top and bottom parts to be moved front and back (by no more than 1-2 mm) - specifically, the set screw will allow the bearing to be moved to the front. The Z-rail can be kept snug by loosening/tightening the screws on the front bearings.
I’d like to hear Ryan’s take on this, if he has any issues before I spend the time.
