Completed my Makerfarm Prusa 10" a few days ago and have basically perfected getting good prints using PLA 3mm filament, .4mm hexagon hot end, and the stock Slic3r settings v 0.9.9.

I tried printing this guy yesterday and no matter the scale I use the arm, leg, etc joints will not move. I had a similar issue with a scraper that was supposed to hold a razor blade but the thin space for the blade wasn't formed properly.

Anyone have suggestions as far as how to improve the precision of the prints?
