    Do you see that the screw is actually turning for all of the 13 seconds?

    pshavela,

    Can you either provide screenshots of the injection and recovery page (if separate) or just the values to the settings and outputs below.

    Shot Size
    Transfer position
    Cushion
    Screw RPMs (if in % please provide max RPM rating for machine)
    Back Pressure
    Screw recovery delay

    If the screw is rotating the entire 13 seconds then you are either having issues feeding the material, or the shot size is too large to recover faster than that. Any type of delay would stall the screw from rotating until that delay was over, meaning if it was recovering in 1 second before, you could see the screw just sitting there for 12 seconds and then rotate for 1 total second. If you provide the information or screenshots for the above I can try to help further.
