eMAKER Huxley 3D printer

Finally got this running sweetly. Three problems:

1. Loose drive sprockets. Fixed with allen key.

2. Wrong skeinforge profile. Fixed by copying them from the github repo and manually clearing out the .skeinforge folder and putting them in.

3. Wandering filament in the extruder drive - it kept on being squeezed out of the hobbed area on the drive bolt. Fixed by printing a special little shim to drop into the extruder chamber to keep the filament in place. Unsubtle, but it works. www.thingiverse.com/thing:14502
