I have a small engraving/cnc machine and I am thinking about future projects. Really want to work with Blender to develop some files to cut. One piece of software that can run a CNC machine would be BlenderCAM. Will see about getting it installed properly on the laptop. Last time I tried, it didn’t work. It may have just been an outdated OS issue. Fingers crossed.
Relief with Blender
Well, now we are talking about using software to get us there. Here is a sweet tutorial that gets us started. In sculpture, this low relief process is called Bas Relief. Here is one video tutorial that explains the process. This time-lapse video may give a few hints on creating the low relief in blender. This is a detailed description using Z-brush.
