5th Gen -- Help printing w/o raft for smooth base?

[pa9k]

Do you mean how the first layers of the floor seem to have space in between them? I'm sure some pics would be helpful. Does the one I've attached look like what your referring to (ignore the leftover raft material)? I've often wondered this myself. I haven't been able to solve this issue yet, and I hope someone can chime in with some advise.

That looks like left over supports to me. Are you using supports to print? If so MakerBot Desktop maybe inserting tiny supports underneath your object, especially if the bottom of the object is not flat.
