    I have one unit, the second unit where the cylinder pressure does not work. When I turn press on it will twitch and that's it. The indicator on screen flashes constantly. On the other hand it will OCCASIONALLY move and set when programmed during setup.
    Computor problem or servo problem?

    Most likely servo, the built in potentiometer may be failing or the gearing is binding from wear. That being said, it could be many other circuit related issues, but more often than not, it's the motor/pot ***'y.

    Sorry for the inconvenience - a limitation of the (global, not per message) anti-spam filters right now.

    No problem, Admin... I immediately saw the filtering and thought it'd be fun to give you folks a little grief!
