Pen Plotter

i've had this idea kind of bounce around my head for for the past two years at least. And i'd occasionally like sketch out some things to try and figure out how i would do it. So instead of using belts and pulleys, which is very common for these kinds of thing, or a linear rail, is also common. I've just got a rack and pinion gear that i've lazor cut out, and it's actually working surprisingly well. The final piece of this all is writing the mico controller code in c plus plus to get it to all work together.
