Man, that first layer went down like a dream following their settings (45°C on a glass bed with PVA).I just went with the suggestions here: http://taulman3d.com/best-print-settings.html
And make sure you dry it out really well before you use it, because it absorbs water to the point where your printer will hiss and pop when it prints.
Also, print slow (say, 30mm/s or less) - since you're printing small gears you might want to go even slower.
I'll see in 3h or so whether it comes out. Looks a little stringy between the gears right now. (E3D metal hot end with hardened steel 0.4mm nozzle and a metal extruder tension mechanism).
