Just received my SD3 last week. Do the extruder calibration where you measure 100mm from the top of the extruder assemby and mark it. Then manually tell it to extrude 100mm. Measure the difference and then scale back the extruder steps per mm in the EEPROM.

Then, measure the filament and do the test print where you have 1 perimeter and zero infill. I had the exact same symptoms. Too much extrusion and the nozzle was ruiding over the previous layer like speed bumps.

A lot more useful information is on that wiki, and there are also various useful calibrations listed at the Solidoodle company wiki here.

Do I need to calibrate how far each turn of the Z control shaft moves the bed?  Is this sometime I should be changing with a setting inside Repetier?
