I have a Chinese Ping Pong robot that is delivering balls at twice the frequency outlined in the specifications. Unfortunately, few of the system components are labeled with useful details.
The System is 110 V AC connected to a power supply/converter which is connected to a circuit board. The circuit board is connected to a digital controller (settings 1-9) for 3 independent motors (1. Ball Frequency, 2.Ball Top Spin and 3. Ball Underspin), and to the three motors. (Motors 2 and 3 work properly.)
The settings 1-9 appear to increase/decrease ball frequency ratably, however 2x (65+-165+ BPM) faster than Spec (30 - 85 BPM)
I replaced the Circuit Board today - No Change in the operation of the system.
What to replace next? The Digital Controller? The Motor (Frequency gears driven by the motor appear to be working properly)?
Is there an easy / safe component that I can place between the circuit board and motor to step the RPMs by 50%?
Thanks for the help!
