I have a Neva profile just about ready to go. Been using S3D exclusively with my Neva for the past 2 weeks. A couple more tests to perform to finish dialing in the first layer settings and I'll be publishing it back to Simplify3D.
I am in the same situation, and I confess to be a little disappointed .... I bought the software, because the Dagoma Neva was supposedly compatible, yet at the opening of the software there is no profile for the Dagoma Neva.
