This video exactly describes my issue, thank you for taking this video and uploading this

A rumour about new Stern pin: JP.

Curious, why are you guys cutting the tabs off of the eject hole inserts? When I replaced mine, I left the tabs and have never had an issue with the T-Rex eating the ball or the ball rolling out of the hole.

Same here, works every time.

I had this problem once when the slope was not good after moving my pins around, are you sure your apron is good maybe try to masure slope on the playfield directly?

That’s a really good point, I’ll check that tonight

JP and not JW?

They can go start their own Stern club, then! No way Stern puts out a better JP than what we've got in the DE version.

I have the same opinion about a potential Stern release, however I have some $$ set aside and space for 1 more pin if I'm wrong

I found another way to easily trigger this issue with the trough "mostly" full. Go into Diagnostics and use the Flipper Button Ball/Trough Clear function. Grab the ball before the auto launch (I suggest using a magnet tool). My machine fires the auto launch (with no ball) and then the VUK kicks four or five times.

If anyone with a working copy of the game wants to try this for me, I'd be interested to see what your results are.

Well, best explanation is because the original ones had the tabs cut off (or at lease what I assume was original - same was the case for the one in the Boat Dock).

I first tried it with tabs intact, but had issues and was getting hung all of the time. I followed Lonzo's instruction about cutting them off and then sanding/polishing them flush, but still had issues. Now things are much improved, but ball still getting hung on occasion. I just played a game and ended up tilting. Frustrated, I found and ordered a 25mm spherical grinding bit, so I plan on emulating the hole contour of the original to hopefully fix things 100%.

Ultimately, the main issue is probably the shape of and wear in the area which is why different people get different results. Just to be clear, I have no issue with T-Rex or with ball coming out of hole. It has to do when the ball enters the area and certain angles it rims out and then rests below the hole.

We’ll see, it’s going to be interesting for sure.

I tested this again tonight and here is what I found. After chaos mode begins and all six balls are cleared from the trough, there seems to be an issue when three balls are in play and the other three drain. The vuk will fire once the three balls are in the trough but the TBL will never activate again until the other three balls drain and the game moves onto the next ball. I hope that makes sense. I can upload a video if that is helpful.

Thanks

I wonder if anyone with original code can test this mode to see if it behaves the same.

At my pinball league right now and someone just actually mentioned that, it might be a bug in the code.. Would anyone be able to test that ?

A stern JP with bubble head T-rex bash toy, two large hit targets with "Jurassic" and "Park". Two ramp. 3 pop bumpers without JP logo top on it.

Another raptor bash toy under the ramp (same as Munsters)

I can pop my original roms back in tomorrow if I remember where I put them and where they go. Unless anyone else wants to give it a go...

That's a no go for me. I can't find the old roms. I probably ditched them.

When I bought by JP, the previous owner included the old roms, if interested I can mail them to whoever needs them (assuming it is the correct version).

For those having issues with the 6 ball multiball searching and attempting to feed a ball after all have already been fed onto the playfield replace your diode on the end of the trough switch. I believe the issue happens when 5 balls are rapidly fed not every one gets registered by the switch because of diode or switch issues. So the game thinks only 4 of 5 have fed and attempts to keep feeding a 5th ball that already left unregistered. Hope this helps

Most of us have no diodes because we have the new trough board. At least myself and one other guy with the issue have this board.

I was assuming he was talking about the mini switch for the VUK. I checked it and looks like it will be a PITA to switch it out. I think I'll wait this one out.

PM me if you have a scoop mod set you want to sell, thanks.

Something wrong with buying straight from the guy that makes them?

https://loopcombo.com/products/jurassic-park-scoop-light-set

They are a great addition, and I can't see many people removing them once they are on. Heck I got them sent to me from New Zealand, faster than Marco can send me a shipment

Correct, the switch on the right just above the solenoid to kick the ball up into the lane, shows as trough #7

Alright, ill check it out. Honestly if my game would just realize there is no ball in the vuk, and would try and release a ball again, I dont think I would have a problem. My switches all check out though, and I replaced the one on the vuk. Ill check out the diode though.

Yeah, no way anything Stern can put out today will make me think that it will be better than our JP's. I'll play it no matter what, but if it's a JW only theme, it won't feel like a true JP machine anyways. First movie was just okay. Second movie was garbage.

On a secondary rant of movies in general, I hate when the sequels think they need to be different. We loved the first one for a reason, we just want to see more of the same. I think 21 & 22 Jump Street nailed this. They even mention it in the sequel.

Is jp stern confirmed? Sucks...no way we get a cool mech. Was hoping jjp at least.

Seen it here and a friend was talking about it. I think so far my friends been fairly right about the rumors he hears. Which is probably here on Pinside. But he said it's going to be designed buy the guy who did Medieval Madness.

Yes, Brian Eddy, the designer of MM and AFM was hired by Stern. (George Gomez announced that at TPF.)

We are due for a game from him or Keith Elwin next.

Stern has announced they will reveal something this weekend at ComiCon. Everything else is rumor.

Stern JP:
-2 very simple cheap ramps
-T-rex on a spring, they call it "toy"
-Photoshop playfield
-Everything at the back, nothing really to shot at lower playfield

Brian eddy tho....

I own a shadow so im an eddy believer. Let hope they dont neuter him.

Finally fixed my eject shield for good. I ended up using the 25mm sphere grinding bit to grind down the lip so that there was no flatness to it at all - only a slight slant inward towards the hole. Sanded it (unfortunately, only had 400 grit), buffed out with Novus, and then waxed. I can't even get the ball to sit on the lip when I try to purposely place it there by hand now.

Can't really see the scratches from player's view (too small and far away), but I'll fix that when I get some higher grit sandpaper. My teenager is having 4 others come over this weekend, and I really didn't want them banging the heck out of the pin if/when the ball got stuck.

Glad you got it fixed.

In case you didn't see the new thread. Sterns big ComiCon is announcement is they are making a home version of Star Wars.

However, Stern likes to do controlled releases from their home base. Remember when they streamed Black Knight right after TPF?

Cliffys now makes a protector for that scoop. Sure is nice, great fit.

I don't see it on his site. Link please?

When I dont on his site I send cliffy an email about it. He is good at responding to emails

Wanna bet?

Thank god no!!!

It's been over 2 years and now I've decided to get JP up and running. I'm missing my pop bumpers wiring....can someone please share a few photos?

Thanks for the link. Some photos are huge help. What I cannot see is the six black wires for the pop bumper lights. I have reviewed the images posted on a shop out job but can see where the wires are located.

Best I have at the moment

Thank you.......it helps.

Hey everyone, I pulled some parts off my JP and listed them for sale, if anyone needs any of the following, hit me up:

Note to myself......never again will I trust uploading photos to a cloud service. I uploaded detailed photos of all the tear down photos 2 years ago of this JP. I waited and hoped there would be a new subway ramp available......well does not look like there is going to be a replacement made. So I have spent hours looking a every photo I can find online to get the pop bumper lights wired up. My final list of parts shipped from Marco yesterday......Hope to have it back up and running by Thursday night. I have an idea on repairing the subway ramp. I will share my thoughts and photos.

What are you supposed to do if you want to play some 9-ball?
