Step 7: Cool air, raft release, curling

Picture of Cool air, raft release, curling
I read about this in the forums and it works for me.  Block off the side openings (I used paper and masking tape).  Don't allow breezes from cooling or doors to enter the chamber while in operation.  This helped solve my problem of curling and separation from the raft.
