Callibration instruction by Mircea Russu: https://groups.google.com/forum/#!top...

Equation for calibrating steps: The steps you asked it to move divided by the number of steps it actually moved, the total of which timed by the number of steps in the firmware. For example I asked the extruder to retract 100mm. It only retracted 97mm. My steps were 800. 100/97)*800=824.7422
