I recently finished building a reprap prusa 12x12 and have printed about 5 items. However, i can't seem to create a raft when i'm printing. I have activated the raft and circling following information i found online but the printer won't print the raft. Here's the screenshots of my raft settings. If anyone could let me know what i've got wrong, that would be great!by dprilutsky - Skeinforge
