Hello, I'm very new to this 3d printing, matter of fact, I'm new to the 3 d modeling software. So we did the drawing attached, and when we print it, for some reason it fills in at the base of the 45 angle and it also cuts a little of the top off. Robo support told me to adjust my z axis, and i did their recommendations with no change at all. We've designed it in Rhino 3d and in sketchup to the same result. any. When i have it show the layers, it shows it exactly how it prints, but not in the print preview.. any ideas? Im pulling my hair out on this one, we've redrawn it several times, uninstalled and reinstalled matter control, tried it with a different machine... any ideas?
