anyone notice that when you plunge the ball, the left ramp diverter (on right side over the shooter lane) always pulses as if trying to divert a ball to the ESP hole). Odd behavior that has been on it since 1.05.

Pro model only since that is the only one with ramp diverter I think?

yup, noticed that too. thought there was something wrong with my machine until I saw others doing it too.

Technically it is adjustable in the menus but just not for strength. You'd have to cut some length off the opposing shaker arms to make it weaker.

Adding anti-rattle tape (Flipper Fidelity sells it) to your glass makes the biggest difference.
Stern's new backbox is louder too so you need to add a couple of pieces of target foam, or thin door seal to the top and bottom channels where the translite sits, to quell that noise as well.
I've even put a couple of small pieces underneath the speaker/DMD panel to help with that noise too.

Here's the trade secret to shortening a spring.

Figure out where you want the length to be. Maybe mark with a sharpie if you want to. Now, put it on the 90 degree angle of the top of a metal vice at a 45 degree angle to the top (you could use something else but it needs to be hard. Timber would be no good)

Now ... smack it with a hammer! The spring now looks like it is at 90 degrees at the mark. Now, grab wire cutters and trim the excess off to suit.

I was taught that trick by a diesel mechanic when I was a kid. Works every time.

With the PBL springs, the ones fitted to the Pro I have on loan at my house (thanks Chris!) were bending the plastic targets and making the drops fall and they would machine gun. That's pretty hopeless to be honest. The targets are so flexible, they bend and fall off the locking ledge. To fix it, I reversed the bottom washer to the inside, which created more angle and the target now locks 100% on the ledge. Easy fix.

Personally, I would have just shortened the stock springs a little. Takes 2 minutes and costs $0.

For the springs (just to make sure we're talking about the drop springs and not the hex post on right ramp) -- I think it's easiest/best to just loop it somewhere mid-spring and leave a little dangling -- that way, it's reversible for the most part once the target loosens up. You don't want to cut it too short and then realize the target can't stay up because the spring is too strong...

I don't believe the diverter activates on an auto plunge, only on the manual plunge, it was more like the diverter was tied to the switch in the shooter lane before the ball had been validated. I could be wrong.

You need to adjust the weights,I wish stern shakers were more like jjp,they just seem smoother and just feel better but I adjust all my shakers so they don't vibrate so much.

Yes, I kind of like it because it lets me quickly verify that the diverter is working when I'm checking my game on location.
