I have been looking into building a 3D printer for myself and the hardware part of it seems simple enough but the only part I am not confident in doing is the controller part of it. I was thinking about using the controller from printrbot (link) and possibly change some peramiters if I needed to for the increased size of my print area. Would this work if I made a custom 3D printer with about 20'' by 20'' print area? (don't know how high I want it to go) I figured it was easier to use this controller than using an arduino and learning how to do that. Any help would be apreciated.
My other though was to just buy the printrbot simple for $299 which only has a print area of about 4 inches cubed and use that to get started as I have never had any experience with 3D printers. Possibly after that I could use that controller to make a larger one? Any thoughts?
