Hi GORDYKD,
I'm not exactly sure what you are asking but the TeachMotion C# example include with KMotion has code to utilize a force feedback joystick. Besides the simple on screen joystick (used in the video below), or a standard Gamepad, if a force feedback capable device is connected the program should detect it and utilize it. With the idea being that the operator could then feel how close an axis is to a restriction, or potentially the force being applied by the machine. Microsoft's DirectInput API is used. See the file ForceFeedbackJoystick.cs
