Quoted from 85vett:
Yes, but you aren't complaining about a coil rapid fire condition. Once that happens you've gone to far. Any pinhead that does any work on their machines that has a basic understanding of how a pinball machine works knows that.
I give up. For anyone that wants to fix your machine PROPERLY this is the WRONG way to do it. Vibrations causing a fire of a coil is damn near the definition of a mechanical problem in a pinball machine. Their is a reason why experienced techs will put a game in switch test mode and lightly tap on the PF when they get a complaint about a flaky switch.
+1 for tech help from 85vett
Maybe some add that I have overseen or not taken into account on the sling issue. For people that want to go a little deeper into the theory. If you hit with your hand on the playfield you want to have something like a dirac pulse (https://en.wikipedia.org/wiki/Dirac_delta_function).
Like 85vett told you, first you have to understand the mechanic, then you fix or adjust it. Software adjustments should stay at the point where the producer set it. For a properly working and adjusted mechanic there is no need to adjust it after a software update.
I'm also working every day with pinball machines a long time and set up a lot of tournaments up to high level. Hopefully it help beginners or non experienced people to keep the fingers of the software adjustments.
