Thread: Focusmax stops

  1. #1

    Default Focusmax stops

    Hi All,
    I know it is not an ACP issue, but maybe someone has had the same problem and can advise.
    I have now had the problem 2 nights in a row.
    I normally use Scheduler and have never had the error before.
    But now using ACP for the first time in a while, the problem occurs during an autofocus operation.
    There were other autofocus operations before this without a problem.
    There is also no FMax log for the period leading up to this.
    Any help appreciated.

    Can this be repeated? Can you look at FocusMax while this happens? What might it be "busy" doing?

    Bob, before you posted this, I downloaded the latest version of FMax (I was a few versions behind) and it ran all night from ACP without a problem. So, maybe the problem is fixed. As I can recall, it was not clear what Fmax was busy with because it was unresponsive. If it happens again I will report back with the details. Dale
