I have to mirror what Kevin said. I have the same printer and I too got a decent print the first time I fired it up. When it came to tweaking and calibrating, I was already ahead of the curve because having built it, I knew what every part was.

Kevin, how do you like that Hexagon on your printer? I'm thinking about a new head. I have the Magma .4 and JHead .5, both Wade's Extruder and I find it very reliable but hard to work with when changing hot ends.
