When I load in my prints I add support. When I hit prepare to print only the support and the brim show up and nothing else. If I do not add support or a brim then nothing shows up when I select prepare to print. I have tried different files but all of them have the same problem. I also deleted Simplify3D and reinstalled it and it still had the same problem. I am stuck and I don't know what to do. Thank you
Had the same issue in another thread. Got it resolved with a license renewal in S3D (Login again) in a non-company network. Maybe that helps. But now being behind a company proxy with which S3D doesn't work , I again can't print anymore.
