I saw these plans on the DIYLILCNC build page and wanted to create one for my business. I had to scale the project bigger to fit my needs. That being done, I had to strengthen up almost the entire design to be able to span the greater distances. Overall the build was finished in a months time and around 900$ spent on hardware, 400$ controller, and a lot of money on the software to run this thing. I'm using 205 oz. stepper motors from HobbyCNC, a PMDX controller seup, all running on a Windows 7 based PC with 8 gb of ram and a i5 processor. The software I use is VCarve Pro 8.0 for my designing and Mach4 for my G-code reader. The machine is capabile of carving 30" by 34" and 4" tall and can cut almost any basic material.
