The plans include a list of all parts needed, a cut list for the 8020 extrusions, and exploded views. I will also be available to answer any questions that may come up. Parts are made of 6061 Aluminum. Plans use SBR 16 x 1150/900/300mm lentghs. RM1610 Ballscrews, and BK 12 bearings. These can be bought on Ebay. Great for the hobbyist, or professional. This kit can also be made larger or smaller by simply changing bearing and extrusion lengths in X and Y axis. I can also make modifications to fit your needs. CNC Router Kit | eBay
