Stephen, I agree, that EMC and associated software can do a GREAT DEAL more than just interpret and display g-code, but Riley seems to be a 'rookie' just trying to understand the basics of EMC architecture and use. Knowing all the hooks are there is great, but right now he appears to need to know the 'main functions' and general use characteristics of EMC and the AXIS user interface for EMC.
Riley, Keep asking, so far all the answers I have seen are correct. But like the old tale of blind men describing an elephant when being placed near different portions of the elephant, we all see it and interpret what we see from a different angle. None of the interpretations are wrong, some may be 'more correct' for helping you understand the portions you need to start getting EMC2 and Axis to be useful to you. Steve has a greater understanding than I do (I learned some stuff from his post to you) but it may be more esoteric than you need at this moment. It is still good info! ... But again, that is my perspective of trying to describe the 'part of the elephant' that I am touching. Hang in there! ><> ... Jack Whatever you do, work at it with all your heart...
