I am no expert with EMC2 and am just starting out myself but it looks like that is what it was designed to do. Your problem will be interfacing. I think it was designed to use a servo control board to act as a buffer for the drives. You are using steppers and there is no buffer in the drives so I don't know if your computer can keep up with live encoder updating to drive in closed loop. You will need a stand alone card to control the motors that does the updating for you, dedicated. I may be wrong....anyone???????
