Your could check out this website:<p>http://www.luberth.com/plotter/plotter.htm<p>In the lefthand frame there is a schematic, click on<p>"More amperes, use TIP transistors..."<p>A pcb layout is available under this. This is an extremely simple circuit - a connection to the parallel port of the computer, and 1k resistors to the bases of the TIP120 transistors. That's all you need, except software for the computer. This will drive 3 axes. Simple software examples are avilable on that site.<p>Good luck,
Grant
