Trying to print out some feet for my printer (http://www.thingiverse.com/thing:1376357)
I am seeing some weird slicing along the first two layers where it seems to break up the item and even print over the raft.

Anyone have any ideas what could be causing this?

The bottom of the model isn't flat. So part of it is elevated above the bed, which is why you don't print that part until the second layer. So either rotate the part until it's level, or double click on it and decrease the Z-axis offset to drop some of it below the bed (so the uneven part won't print)
