Etch-a-Sketch DrawBot software setup
I'll start by saying I'm very new to processing, so please feel free to point out even the most obvious of error in my logic ;)
I've been working on a DrawBot based on an etch-a-sketch (mostly to amuse the little fella) and looking for suitable software for image to gcode conversion. I came across the amazing death to sharpies project which I believe uses Drawbot_image_to_gcode_v2 which I think (?) is based on processing for its image conversion.
Question: I'm looking for some guidance on how best to installed / compiled / executed Scott-Cooper's code - Drawbot_image_to_gcode_v2. It also seems to have several dependancies or libraries any guidance on tracking these down would be appreciated. I guess I'm looking for Processing 101 / Drawbot 101

Thanks for reading, any tips, trick, guides or pointers would be appreciated!

Quick update for anyone finding this post at a later date. Not really an answer to the processing questions but I found an alternative approach using a nicely setup open source app called strippleGen (Looks processing based?) to generate TSP Art vector files these can then be converted into gCode using Inkscape. This looks like a promising approach to the problem but image quality seems to be a little low due to back lash issues with the etch-a-sketch but that's a problem for another day.
