I'm having the same issue with this scaled down. I have tried Cura and Simplify3D for slicing with the same results. The results I am getting is nothing but a blob being created, not even a first layer. So I am trying now with a brim and the first few layers look good.
I am printing on a CR-10. The print is about 60 layers through and it's looking good. Still got about a dozen hours to go!
