YES, V2 IS HERE!
Of course, it follows Lyman's ideas on spooling, but with some new ideas on cooling and spooling the filament.
This work is now working correctly (as of 30/3/2014)

Subsystems:
Extruder.
-It is the original YALFE but with the new voltage regulator.
-i also pulled 12v to supply the other sub systems.
