So, I wrote a bunch of small programs that create the G-code to do the most common things, like rectangular cutouts, round cutouts, etc. I also have some that handle a hole circle and grid of holes, and a table of arbitrary X-Y hole locations. One input file, and it will generate spotting, drilling and tapping programs for all the holes. So, I use this stuff far more than cad/cam, because it is faster to create, and more efficient to machine. Many of these have been ported over to the "scripts" on EMC2, but I have them on my web site, too, at http://jelinux.pico-systems.com/gcode.html That is exactly what I do right now is using my own scripts where objects such as odd circular forms and other shapes are created using Pascal programs to generate the Isel g-code. Scripts are absolutely great for repetitive jobs. The problem though is that I need to make solid stock objects too with limited 3-d features and it is great to have the cad-work/drawings for that so I want to have those done from CAD side. I quoted the wrong link for ems sorry. Here is a good example of about exactly the complexity I do and Linux cad I would like advice on to do similar. "http://www.emachineshop.com/audio/13-advanced-3d/video.html" My question is, is there a simple 2-d 3-d cad program with DXF or such output I can feed into EMC for toolpath generation? EMC doesn't take DXF, it takes RS-274D, also known as G-code. DXF is good to move a drawing from one CAD system to another, but it leaves so much info out of the transfer that it causes a number of problems. I know that, but it is easy to use a dxf to G-code converter.
