Hello. My guess is on your original post was there didn't seem to be a direct question.
Your system should be a good performer. The Emco's have had a good reputation. You are on the correct path for a good conversion.
It appears to me you are requesting info on the various controlling software bases available along with their capabilities? You may look over the Machining Processes, Machine Controllers Software and Solutions section on this board. There are sub forums which deal specifically with the controlling software.
My limited use and knowledge kinda pointed me to the Mach programs. I believe there are trial versions to test out. You may do a search on their web page for more info.
Feel free to ask anything re: your conversion here. There really are a great bunch of folks eager to assist you. JRouche
