Horizontal oscillation only fires to the sides, or just to one spot

Horizontal oscillation will move from side to side at a set speed. Depending on the speed/timing of the feeder, it is possible for balls to fire out in what appears to be fixed positions on the court (eg, one to each side, or all balls to one spot). To resolve this, simply alter the interval speed to be faster or slower and you may find that balls fire out much more randomly.

Since software upgrade M4.1.1 (HM3.6.3; VM3.3.0), the horizontal and vertical oscillation modes added a short pause that varies in time, thus eliminating the possibility of setting the feeder rate so that balls shoot to a single position.
