Thanks for the feedback, half way through a print that is about twice the 
volume of the nut and bolt, and now after having tightened the feed 
pressure, it is like a different machine.
 
I was getting very frustrated, but understand I have a lot of learning 
curve to go, being new to 3d printing and replicator 2 being my first 
machine.
 
I have hope again!
