Maybe a BBB owner might check on his machine:

While powering BBB up, doe the Aliens move in one direction or change direction ?
As far as I could see on youtube, the Aliens are moving only in one direction but the motor emi board get 2 connectors forward and reverse.

Alien mechanic test in the menu.
While testing/justage of the aliens. Do they always stop exactli with the faces to the ramp ?

For the tech guys with a BBB:
On the motor emi is a programmed PIC-chip .. somebody know what this programm is doing ? As far I can see on videos the aliens stop to spit out the balls and afterwards move around without a stop. Might this the pic chip ?

So it goes some rounds to the left and some to the right and than to its position facing the clear ramp ?
Will it also turn in testmenü to the left and the right ?
Also while calibrating ?

Thanks for your help !

Oh yes, he might chime in ! It is not a urgent problem, I am just wondering.
