I am a new owner of the Amicus Butterfly Pro and am hoping for some help from other owners if at all possible.

I have set up in the memory of the device a series of very basic routines just so that the same ball can be delivered to the same place. I am having a problem though - the routines which involve top spin are working fine. The ball can be delivered to backhand or to the forehand and the routine keeps on going as it should.

For some other routines with no spin the device will send out a ball correctly 11 times and then the E2 error message will appear. However nothing is actually stuck or broken and if you either hit the start button or turn the ball frequency down to 0 and then up again the device starts working again but only for 11 balls. Obviously I don't want to have to restart every 11 balls. Has anyone got any ideas as to what I could try to fix this?

Many thanks
