Quoted from Tuna_Delight:Ok - one thing to be aware of, that I still have to periodically contend with, is that the weight of the playfield* causes it to settle lower over time in the cabinet. This causes the shooter rod to catch the automated plunge mech and lose plunging power which in turn, hinders the ability to go for a full plunge skill shot. The short-term solution has been to bend the playfield catches (that hook into the front of the cabinet) back to restore the playfield height and eliminate the plunger conflict.
* No doubt exacerbated by all the damn mods I've added to my game. Curse you Mod Couple and Lior!
I’m glad you posted this. I picked up a used pin a few months ago and have been dealing with this. The original owner had adjusted the mounting of the plunger but that looked weird because you could see the decal cut. So I had put the plunger back in the original position and sometimes had to plunge a ball multiple times to even get it on the playfield.
So I just tried your suggestion and now it plunges beautifully. Wow. What a simple fix. Hope it will last for a while!
