This is probably a very simple issue but I am new to "Home-built" routers and I am hoping someone out there might be able to help me out here. I've been using a Roland PIX-3 scanner for years and have amassed a large number of scanned objects. I have been using an MDX-3 to do the cutting of each part one at a time.(Which is incredibly slow) Recently I have been building a DIY router to increase the number of parts I can cut at one time. I have purchased Rhino 4.0 software and Mach3 to drive the unit. Now the problem: I can move the Picza PIX file into rhino and convert it to DXF or most any other format for that matter with no problem. I can even modify it in Rhino if I wish. However, I can't get the mac3 software to creat a g-code or even recognize the file. I try to load it but it just freezes up.These are fairly large point files generally a scanned relief 3" x 5". I really need to use these scans for the project I am working on. How can I convert them into something my home-built can use? Do I need different software?
