is it possible to change the height of the suspending magnet in realtime? like you start on the top and then slowly move it towards the bottom and then pull up again? i cant find anyone doing it..

thanks.. yes perceiving the time is a little difficult but then hey it was fun . Yes i also want to use it for a bigger robotic arm, may be a scara 3d printer who knows.. i am currently working on a belted version to get rid of the slop . that would be easier to scale and will be more accurate.
