Can someone please help me. I have installed and re-installed cura on my mac book for my BNC3D Sigma and am having major problems. First when I loaded a model it showed as solid black on the bill plate, but, if I move it slightly off the build plate it appears normal. I tried going to low resolution but nothing changed. Now when I open Cura I get a full black screen .. I using OS X El Captain.
How do you totally remove every trace of cure.
Thank you
