Because I can order things on the internet faster than my brain can veto them, I have a Kraken 4 hotend and a Duet with extension board to run it. I've not seen a great deal about the Duet or the RepRap firmware, so this is a general request for any hands on experiences people have had. I'm not going to rush into setting it up as that would take my printer out of action, although I am planning printer 2 already, so it might end up going on that :)
