I wanted test the ability of my Monoprice Ultimate to hand negative space. It did quite well even on the 0.2 space. I sliced it with the version of Cura recommended by Wanhao for the Duplicator 6 (which has been doing a great job). When it was sliced there was four small "links" at the 0.2 space which required "snapping". I squeezed too hard with pliers and tweaked the top of the peg...durp.
