I can't seem to complete any prints anymore on my 10in with hexagon hotend and PLA. I thought maybe it was an issue with moisture with my filament so I spent some time drying it out. Today I tried a test cube and as you can see from the results about iut 3/4 through it extruding all the way. http://m.imgur.com/TaGHP2b,jOWol0o I also have a picture of my filament after I pulled it out of the printer. It's been stripped so only I guess the outside of it remains.

I thought maybe this was from heat creep before but I have a fan on, all be it it's a strange configuration. Any ideas what I can do to solve this. It's been going on for some time now.
