I am looking at building a small format Ox and wondering about what controller etc. I should be looking at for the application, as I am not sure of which would translate to what is shown in the build video. I plan to use the Mac with OSX that I have, 3 Nema23's and 1 Nema17, or 4 Nema23's (if that would end up being recommendable), materials like woods and plastics in 2D or possibly 2.5D relief work, and possibly carbon fiber and aluminum in 2D. I'm also thinking of using a quiet-cut spindle to start. I am basically brand new and still trying to become familiar with distinctions, etc. in final driving code, such as G-code and GRBL, firmwares, etc.
