Thanks man. Well, I'm using my jobs machines. For CAM, we use MasterCAM. Yes, it's expensive, I don't know how much, but my estimates is around 5000-10000€ for a license. About the post-processor. It is specially written for that machine. I can't help you with CAM software, but for a home-made machine my guess is that you are running MACH3 or LinuxCNC? Those 2 controller softwares run with regular G-code. So you could use the generic post-processor that comes with whatever CAM software you decide to use. Yeah, I would totally vote 1 star on this build, why you ask? Slow updates!
