The balls shot by my elite grand machine (four or five limited edition) do not clear the net: is there something wrong with it?

The elite grand four and elite grand five limited edition (le) are fully computerized machines that pre-calculated trajectories (speed, angle…) for the balls they shoot. If more than 10% off the balls are not clearing the net or going out, please make sure that:
  1. The net is 35-36 inches high at the middle
  2. The calibration has been done correctly. If some balls are still not clearing and even if the test ball is landing on the “T”, re-calibrate the test ball to surpass the T a bit and see how that works. The “T” is a guideline but will vary depending on altitude, environmental conditions, and also the tennis balls being used
  3. All tennis balls used for playing are in the same condition
Shall this not solve the problem, please contact us so we could assist you.
