Thanks for the great instructable. Here is the one I made. I used two L293 driver boards. Worked like a charm!
Hi, very nice instructable! I had an idea for a variation on this. Has anyone tried using the geared drive open/close mechanism in an xy plotter like this one? Maybe replace the dc motor that has the small pulley for the belt on it with the stepper motor from the laser slide? Could give you a little bit bigger drawing area. Just a thought.... Thanks!
