To get the extruder to feed the correct amount of filament I had to set the M92 E value pretty high, I think somewhere near 700. The default firmware value was 90 or so. Does that line up with what everyone else has been seeing with this build or is that indicative that I've got something wonky going on?[/quote]

I bought gears from TriDprinting and used the RichRap Greg's Wade extruder modified.......regular NEMA 17 motor 1.9 degree/step.
Printrboard electronics...
M92 X55.50 Y55.50 Z55.50 E520.00
my first attempt, I had the direction wrong and just reversed the connector on the board.
My second attempt, I extruded 25mm and got 50mm, so I doubled the steps from 260 to 520 and then the measured matched the extruded.
The value of steps per unit for the extruder should not be a guess, it is based on the number of teeth on the gears isn't it? and the degrees per step of the motor.
Anyway you can calculate the steps per unit for your extruder.
