This is an overview of what the whole plotter looks like to give an idea of how it is put together.
Don't look too close because I stitched that picture together from several closer ones and the seams aren't perfect.
If you look back to the early posts when I started you will see that I started with a Basic Stamp project board from Parallax. The motor drivers I built were designed to plug in to that board where we used to plug in radio control servo motors for a different drawing machine we had built. Now that I have switched to using an Arduino to control it I kind of made a dead bug style adapter. I am going to get a proto board and build everything on there in the future.
