The latest version is on the web page
www.vitalsystem.com/dspmc. The above AxisWorks is one of the alpha versions that was buggy. It was not released for general use.
You do enter PID settings in a separate window. you don't have to close it while you work with the graph. leave it open so you can re-enter values and see result in the graph.
Will be updating the manual soon for the latest AxisWork operation.
thanks
