Ideamaker has tons of profiles for various printers. Somewhere in this great big interweb thing I read that it's a clone of Simplify3D, but with more recent improvements. I paid a bunch a bucks for S3D and probably won't advance to the next (paid) update unless ideamaker doesn't build a profile for the Sigma.

I think one of my references to flat was misconstrued as level. I tried to clarify that in a later post.
