This plotter started as one of the "Ultimate Builders" projects. The paperfeed from that design looks oke, but it is not accurate at all. So my plotter now drives on a 4 rails made from Technic Gear Racks (3743). I also use 2 rotation sensors to measure left-right and forward-back movements.
It is far from perfect, so this cries for a Plotter #2....

I wish Lego would include the technic gear racks in a special technic pack that you could buy online... I have to buy them from brick link because there aren't any Lego stores nearby. Awesome job, though! :)
