At a guess, I'd say the problem is that the third domino is hitting the fourth with
the most
force out of all of them, and the settings somehow aren't correct, so domino 3 goes
inside
domino 4. I still mainly guess what settings to use when I use mechsim, so I can't say
for
definite, but it could be that your step is not small enough.

If this doesnt help, then probably better waiting for Christoph to reply.

All the best,
