Hi I'm new to open builds not really new to CNC though however my CNC machine is a carvewright which uses a proprietary software which you don't get to see anything except the CAD part, you don't get to see any cam or post processor parts all that stuff hidden you don't get to see it. I would like to build a machine from Openbuilds. I really do like the C-beam plate maker. I do have some questions about post processors. I'm very familiar with SketchUp and very familiar with sketchUcam, however I don't use either one of those with the carvewright, but with the Openbuilds C-Beam maker I want to know do you also need to have a post processor such as mach3 or Linux CNC.
