“I managed to get a huge drawbot working, with a serious rethinking of the hardware. In the end it was an Egg of Columbus, and I’m proud to have discovered it: you can avoid all the mess of the electrical wiring from motors to arduino and from arduino to PC, by simply let them all stay very close together and making only the fishing line go around the drawing area, driven by idler pulleys! … It is now very easy to draw on huge areas, and the hardware remains completely unchanged independently from the size of the drawing area! You only need to change the position of the idler pulleys.

I will be disclosing this tecnique during the Makers Italy Fair in Milan (only in italian, sorry). I wanted to share it with you as another mean of saying thanks for all the effort you put in the code. I will be advertising your firmware and your site during the 3 workshops I’ll be doing during the Fair.”

Antonio: Just how big is it? How long does it take to draw that picture?
