DrLuigi,

It might just be the sensitivity of the recording but I can definitely recommend adjusting the pots again to get the stepper motor noise down. My Prusa sits on a sheet of neoprene I cut from an old laptop sleeve and it doesn't make a sound aside from some nice robotic motor noises from the steppers. Then again, I do print very slowly, 20mm/s on all fronts and have adjusted settings in my firmware that deal with jerk speed, so my steppers don't work as hard and vibration is minimal. My thinking is, why print fast and have it look ok when you can print slow and have it look fantastic!
