Get rid of 9.4CH. It has possible bugs, since it's a hack.
If you are sure your geneva switch is working, 100% of the time(*), then switch ROMs, go back to 9.4H. Restore factory defaults, set it up, and give it a whirl.
(*) - Put it in Continuous Mode for a good 30 minutes. If you get no errors after that, then it's good.
Okay, your continuous test failed.
After loading three balls, it was supposed to release one from the gumball machine. A ball was not dispenced. The yellow handle on the front did not turn. The motor didn't even try to run.
Likely you have an intermittent wire connection to the motor, the motor driver board, or the motor is locking up.
Quoted from the-ace:Yes, no ball dispenced
I soldered the cables on the motor in the last months, they have a good connection with solder lugs.
The strange point is that, when I do the "empty gumball" cycle, the engine turns without problems.
Another thing I could try in the next days; remove the gearbox of the gumball machine, open it, clean everything and put some new grease on the gears inside.
As you can see in my video, is my geneva switch working correctly?
In the dispense all, yes. The error is being thrown because the CPU is telling the motor to tuirn, and it's not seeing the geneva switch close - because the motor's not running. 
Quoted from the-ace:Does anybody know the right direction of the gumball machine's white disc (when looking from above) and of the yellow knob?
When one ball enters and sits inside the gumball machine, in which direction must rotate the internal separator? Clockwise or CCW?
Looking from a player's perspective, the yellow twist handle rotates clockwise. The white base and red piece that feeds balls travels counter clockwise. (Yes, they are directly connected to each other.)
