When I start a drill, it runs as set at the beginning. After 2-3 rounds, the ball machine adjusts itself and then throws the balls 1-2 points further forward from the direction. For example, instead of 14, 12. This continues throughout the whole drill and I don't change it anymore. It seems as if the machine is then incorrectly calibrated. If you turn the machine off and on again, it works correctly again, but only for 2-3 rounds. Then it runs incorrectly again. What is the problem? Thanks
