I don't think you know what you're asking for. A post-processor works in conjunction with CAM software. It converts the pretty lines you see on the screen into code custom tailored to your specific machine and needs. So if you truly are looking for a post-processor then the first question will be "what CAM software are you using?". But your reply where you mentioned BobCAD sounds like you don't want to use commercially available CAM software. So you are looking for someone to write, not a post-processor, but a custom program to take DXF files and convert them to G-code that doesn't run in existing CAM software. Does that sound more like what you are looking for?
I agree to some extent, but mostly that I misstated a bit. The company who writes the nesting software won't make a post-processor for this machine. Why? I'm not sure, I don't have access to that info. I've been asked to help out on something that I only have limited info and I didn't think it would be this difficult to find a solution (my bad). So, the nesting software will output a DXF file, which is currently being pulled into the CNC machine, which we then have to "massage" manually for this machine as it's post-processor isn't ideal and there is no way we can get it and modify it. So, I agree it's more like actual CAM software in functionality but it does require a custom post-processor for this rather "unique" machine which is a cheap made-in-china POS but it will get the job done (currently in production).
I probably shouldn't have mentioned BobCAD, that just created a bunny trail, but it might be an option to pull it into that if they can write the post-processor. It's just that we don't really need the CAD portion, we just want something to take the DXF and convert it fully over into the correct G-code format. It's a very simple program, again, you just don't want to have to manually manipulate it each time, many times each day.
The other option might be to post-process the output of the Chinese-made controller which would be a true post processor. Here's the Wiki definiton in case there are doubters: "A Post Processor is a unique "driver" specific to a CNC machine, robot or mechanism; some machines start at different locations or require extra movement between each operation, the Post-Processor works with the CAM software or off-line programming software to make sure the G-Code output or program is correct for a specific machine build."
So, while I might need more than that, at the core it's still what I'm looking for.
Thanks,
