Rolf PM'd me about this, and it looks like you figured it out!
But anyway........

I think your stepper isn't set up right.
I had the same problem.

In it's home position, all the way ccw, the contacts should be on the last two rivets, making contact.
in it's extreme position cw, the contacts will be off the rivets, and the limit contacts (the leaf contacts)
should be made.

As you stated above!

Are you having any problems with it scoring too many points?

My machine has been a real bitch so far.

Good morning, Dave

I have my game set to three ball play.

First two balls give 1000 bonus points per drop.
Third ball, double bonus lights, and it awards 2000 per drop.
I have never tried it on five ball play.

Read the thread that Rolf mentioned about the bonus scoring. I'm pretty sure my problem was the timing
of the associated motor switches.

This machine has been a real pain in the ass lately.

I will pm you my home # feel free to contact me.
