Hello, I'm setting up a servo (Tower Pro SG90 9g micro servo) with the blackbox. I've successfully flashed the 2axis + RC servo firmware. I've removed the relay jumper. After calibrating the servo with 0 corresponding to pen up and 255 corresponding to pen down, i'm only getting about 80 degrees of travel. The servo is capable of about 200 degrees. I've used this same servo with an arduino before and was able to get the full travel. Am I missing a setting somewhere? thanks, Wolfgang
