I have the same problem with the bulk filament.  It started taking it and then quit.  Tried adjusting the pulley but I almost think it doesn't get hot enough to melt it.  When the stock stuff is in there and you remove it and put the bulk in it works for a minute and then quits.  Almost like the melted stock material help heat it until it's all gone.  I can't really tell if the hack works or not since I can't get the bulk material to flow.
