My favorite slicing program has released its latest incarnation!
Bounce on over to Slic3r.org and grab Slic3r Version 0.9.9
Slic3r is finally offering a raft function.
Many new features, including a new simple mode, raft and the ability to use multiple layer heights in the same print, and optimizations for printers with Bowden extruders. And, of course, LOTS more.
