Hmm, how the hell do you calibrate the Y, we got to the page were you move the Y, it ask you how far it moved, we punch in how far it actually moved and then test it and it moves exacitally the same WRONG distance?!?! Do we have to restart the PC or is it not needed to take effect? Also, it gives a "jerk' after we tell it how far it moved, is that normal?
