yes, i researched and found some posts etc that the open is down. I re printed my shelled out z nut holder with 100% infill this time, and it appears to be rock solid in there now.
so once i get a moment ill re start this thing.
Luckily it isnt too bad, i just had to go in to inventor and take my border from .75 inches to .37 inches, and i should be able to salvage this board.
that is unless there are more issues 🙂
