I am new to the cnc world (milling) and would like to get a conversational software program. We borrowed Autocad and all I can tell you is forget it. I have heard of two, Bobcad, either the v19 or v20 or another much less expensive one called Kipware. Does any one know much about either and would anyone recommend one over the other. Like I said previously, this is all new to me. Thanks.
