Functioning
The motor drives a worm gear with a 24t which drives another 24t. Two crank-connecting rod system give the wave movement to the main banister. A other crank-connecting rod system with a push bushing operates the lifting of the drip tray. The module is quite reliable but can not take a big bunch of ball in one time.
