The "external driver " (connected with USB) has an internal motion controler (with its PID) and its input ( PC--->Driver ) is similar to stepper motor. Obviously, the data input is buffered (into "external driver") to allow the "external driver" to observe the trajectory, and allows the USB sending data in not realtime. The average throughput of the USB allows that. The "interface" from EMC to "external driver" for me would be to have EMC generate the positions and axis directions and provide them to a "external driver" . Do you think it is possible to realize this type of interface?
