My computer crashed so I bought a new one.  everything works great but for some reason it does not respond to f codes.  I have to set the speed by using override on the main screen.  I has to be something simple but I cant figure it out.
i.e.  if the program says f20 it runs wide open.  if the code is f3 it runs wide open.  I can only control the overall speed on the main screen override.
Thanks
