This is the same object printed two separate ways. The side facing down always comes out tapered. I should also add that I'm using Simplify3D to position the object on the print bed. They have a large number of settings which I'm still figuring out. I set it up for "print quality high" and let the system auto configure the settings. Given the size of my objects I am not able to just "print two". If it's a small part or large part I get the same taper affect:
