YouTube says "Sorry, that video is private." (I assume it will tell endymion the same thing.)
For endymion: Sorry I didn't chime in back when you originally posted. I've been doing a bunch of tuning myself lately, using the MAKE Magazine Torture Test object, and I'm getting a better feeling for the settings and their sensitivity. Looking at the photo of your part, I'd suggest increasing the Extrusion Multiplier, especially if NG3D's FFF profile has reduced from Creator's default value for the Rep2X. Once the layers fill in pretty well, start using the retraction and coast settings to get rid of blobs and stringing (by increasing them) or to get circles to complete (by reducing them).
Sorry for taking so long to get back.
I thought it would be easier to do a video to show you how I have been going about fine tuning the profiles.
