You will be able to operate certain functions of the machine from there also. Yes, DST, EXP, CND, OFM and many other file formats are compatible for use. The "buttons" on the machine is the machine keypad or "Interface Assembly" . This is much more than a fine tuning device. It basically controls all the movements and functions of the machine itself. It also has the Emergency Stop button on it. You cannot start the machine running from the computer, the start button must be pressed on the keypad.
