I took the plunge and ordered a C-Beam bundle with steppers. Now I am looking at the different boards and am getting more confused each time I search. My main concerns are ease of use and quick setup and getting up an running. I am looking at the xPRO V3, the Smoothie Board and the TinyG. I really want something that has been built and running before so I am leaning toward an XPRO because of the video by Mark Crew. And the idea I can use a computer power supply cause I have a couple hanging around and it will save me 50/100 bucks. Then there is a software issue. I work in Autocad and was looking at Fusion but need an interface between the board and Fusion. Smoothie Board seems a bit more featured but it also seems to have a steep learning curve and uses a serial port to transfer code, at least that's my take on what I read so far. Then we have TinyG which I have skimmed but not looked closely at. So what are the advantages disadvantages of these? And what software can be used with each package. I am most likely gonna get the electronics in a week or so.
