Sorry, no running total. I spent about $310 at Openbuilds for the 3 V-Slot Linear kits and 2 additional pieces of 20X40 extrusion, a handful of screws, nuts and a large gantry plate. I had some leftover lexan from earlier mods (ebay). I looked over a lot of "builds" using Openbuilds stuff and just tried to be as simple as possible. Since this is a non-contact "CNC" it doesn't have to be built like a tank. The brain fun was reviewing all my options and figuring how to build it. Sorry no 3D cad files unless you can do a Vulcan mind-meld on me.
