Hopefully this will help someone, but I wasn't able to get it working freely at first when my spool was oriented like toilet paper should be - that is, with the filament being fed from above the spool, rotating clockwise. When you re-orient the spool to feed filament from underneath (counterclockwise) i was able to get it to stay put and move freely.
