Although each JP owner can do anything they want to their own machine, I think removing that post is a BAD idea. The post itself is designed to connect/contact with the ball coming off the flipper (the ball should not simply roll off the end), and it also prevents any high speed ball from smashing into the tip of third flipper when driven from the left flipper. I would put that post back if yours is missing, but again, that's just me. Anyone can do anything in the world of pinball!

(It's possible the 'plug' is simply a quick fix for a previous owner than broke the original post and didn't want to wait for new parts to put the machine back in operation)

Optos fixed mine
Yay
I have a working game now.
Still have 1 set of playfield holders available, black only PM me.

Glad you're up and running. My backbox clicking at boot is back even with new PDB. Will see what Stern says .

Mine is clicking more. 5 to 7 times every time now.

Our Premium arrived today. Added the shaker motor while I had the PF up to check all the connectors before power up.

Really special to have the 30th Anniversary decal on the backglass for this year's run.

On that 30th note - its jurassic June!

Is anyone else getting an occasional stuck ball against the post in the center of this picture? It's near the entrance to the pops at the upper center of the playfield.

My post isn't in the center of the natural wood 'dot' on the playfield and this might be causing the issue. For now I've replaced the rubber ring there since Stern's seemed a little plump.

Yeah, I've noticed it can fail occasionally. Usually it's a weak shot that seems to break the opto, but not get far enough to be grabbed by the magnet. It also looks like occasionally when it's in the "down" position it'll be a little off center, but that's something that can probably be adjusted. Mine gets probably 95% of the shots it should though, so I'm not too worried about it.

The one shot that does seem like it needs a little tweaking is the helipad though. I played another JP this week, and that was much smoother than mine. Incline might be a turn or two too steep-may have to experiment a little more with it.

I just found out my wife has never seen the original (or any) JP. She's quite a bit younger than me, but FML still....she loves the game, will see how well she likes the movie here soon. LOL Hard to imagine getting all the way into the game if you have no idea about the "world" or any of the concept. Dammit.

Hello, this has probably been covered hundred time but my t-Rex doesn’t go left right anymore ( up right and mouth are fine so the game is playable ) and if I test it on the menu the game just freezes. Probably something went broken/unplugged? ( notice the game is somewhat more easy as the T. rex on that center position always drop the ball on the rail,)

Just don't watch the second one under ANY circumstances. Trust me.

Do you have the 48v coin door switch pulled out? It will freeze if you don't have that pulled when you try to test

If any new owners are looking for the stern armor set I have a spare set. Prefer local sale over shipping. Pm me thanks!

Hmm, sort of not to familiar with stern pinballs, where can I find this switch?

White switch on left inside door. Same one that gets depressed when you close the door, if you pull it out it does the same thing but you don't have to hold it.

Lost World > Jurassic World

Agreed. Which is why Jurassic World is horrible.

Both are garbage.

Almost bought these today to turn into a topper

Hi, y'all,
New member here - picked up my NIB JP Prem. a few days ago - discovered a problem already:
The ball got stuck approx. 12" in front of and about 4" to the left of T-Rex, beneath the tail of a small dinosaur figure (sorry-no pics). I couldn't shake it loose and had to remove the glass as well as unscrew a clear pf plastic to unstuck it. I can't figure out how the ball ever got there. It happened during T-Rex multiball - I think when T-Rex spit the ball out of his mouth. I'm wondering 1) is this is a common problem, and 2) is there any generally agreed upon fix for this?
Thanks in advance for any help.

Yep that's a common stuck ball area under the raptor's tail, although I don't think it happens very often. It can happen when a ball takes a bounce into the air and lands perfectly into the gap between the decorative plastic and the clear plastic protector above it.

In several years it's only happened a handful of times on mine. You can try using something to try to block the area a bit. I'm sure I recall people posting a few different ideas about it over the years. I haven't done anything on mine since it is usually so infrequent.

Building my DIY GZ Topper was fun so I'm going to try to do something similar for JP.

First stage mock up:

Loo

Looking good so far! The JP light sign going between?

I think so yes. Or behind.

Got my warranty optos from Stern today. Stock for later.

REX with the ball you did is really cool.

We're loving the movie code. The only downside I see is not having home team but scanning a QR code once for the session doesn't take much time at all. Probably make a tag with the QR for the Keychain

I got the paddock where you got 2 Dino’s to catch at the same time. The shot flow, goals and tension makes for an Absolutely amazing game.
Sorry just a quick vid of when I caught a break in the action.

Then in trying to figure out what I accomplished I found this:

Hope that helps ruleset newbs to this game. I had no idea the scoring potentials here..

Most shots up the center seem to rattle and lose momentum at the end of the ball guide here and fall down into the bumpers. Is opening up the gap at the end between the two ball guides the fix for this?

We've not had a single ball rip through there. Kills the flow to the right upper flipper

On Godzilla people adjust the guide to the left of the rmagnet all the time by pushing in closer to the magnet.

From your photo Id try to loosen the guide mount below and to the left of the spinner and hold it outward (to the left) when tightening it.

Thanks, will do. I figure it's too narrow and slowing the ball down.

See where mine is relative to the art..Sorry about the poor quality but I don't feel like messing with the glass at the moment.

Oh ya, yours is much farther to the left. Thanks!

I heard Keith on a podcast talking about a ball save rule that was odd by default on JP but on by default on GZ. I think it lets you keep an earned ball save until you use it instead of it being on a timer. Anyone know which number that is so I can go flip it?

EaglePin,
Thanks for your comment on my stuck ball. I won't do anything to fix it yet (as you said it's pretty rare). For some stuck balls you just shake the cabinet a bit to release the stuck ball, and for others you do some sort of pf fix. For this one you must remove the glass as well as a pf plastic to get the ball unstuck. Since I don't really want to figure out a pf fix for this one, my son suggested that a quick temporary solution (like when you have guests playing the game) would be to slide the glass partially down and drop another ball onto the pf - the game doesn't know there's a stuck ball, so as long as the machine counts 6-balls in action, the game will continue normally, then later at your leisure you can get the stuck ball out.

Could you also share a top down photo of your upper flipper? Glass on no problem. I'm curious if ours need a bit of adjustment

Mine is probably slightly off.

yeay! I'm officially a member of the "JP owners club" today.

IMG_2763 (resized).JPG

So I just received my JP premium last week and seems to be playing great. the only thing I have noticed is that when hitting the spinner it seems to hang up on the gate and only make it around to the upper flipper when hit perfectly. Is this normal ?

Look up a few posts. I'm dealing with the same issues and adjusting the guide appears to be the fix. I tried loosening the nut under the playfield and pulling the guide to the left while tightening. It made a minor improvement to that shot but the guide did not move much to the left. Not nearly as far as the other user's pictured. I may need to bend it a little bit

I think some may like that it slows the ball and drops it into the bumpers but I think it kills the flow and it was intended to shoot through and around to the upper flipper

It's up to you how you want it aligned. But ideally for this game on the lower flippers you want the tip of the flipper pointing at the alignment hole, but for the upper flipper the front face of the flipper bat should line up with the hole (not the face of the rubber, the face of the plastic bat). That will expose the post to the ball so balls rolling out of the orbit should bounce off the post and go toward the left flipper instead of SDTM.

Here's a post I found showing the alignment for the upper flipper:

https://pinside.com/pinball/forum/topic/welcome-to-the-jurassic-park-le-club/page/48#post-5292142

Copy that ! Thank you.

Here is my upper. Looks similar to that post you linked. AMartin56's looks like it is over to the left a bit so the ball won't deflect off the post

20230607_183022 (resized).jpg

Seems like your disty would be taking care of all this for you, sending someone out, etc. LOL

Still a work in progress. Going to add a lit Jurassic Park logo sign behind them when it arrives.

That’s going to look great! I wonder if it would look cooler if the ball was in the back of the jeep with an LED under it. Like the TRex is chasing the jeep to catch the pinball.

very cool

I was thinking of putting two balls in the back of the Jeep but then I thought it would look strange with the front seats empty. So then I thought about putting pinballs in the front seats. But then I realized we shoot pinballs in the mouth of the T Rex to feed him. So if the pinballs are driving a jeep that means they are people and we are feeding the T Rex PEOPLE. So I left the jeep empty...

I have 4 more sets of playfield holders/lifts/jacks whatever you prefer, these are the last of the final run of prototypes, we made a few SMALL adjustments based on feedback from the folks who tried them (besides me and my guys) and now we are in production on the final product but these are VERY close and 100% workable in every way and I don't want to chuck them. $20 shipped to lower 48 states, PM me for zelle/venmo/paypal, I have 2 black and 2 orange. Thanks.
Edit: 1 black and 1 orange left now.

Off topic but I also have several pinball cup holders that are our own design as well, these are a little rougher, some scalloping on the sides as they were run quick working on another feature. These are our own drawing, similar to others, but different enough. They'll be sold a little cheaper than others probably as well, but in the meantime I have 4 black, 1 blue/yellow mix and one all blue...100% workable in every way, just not the polished finished product. Assume they'll cost $5 to ship, so call these $10 shipped to lower 48. We'll probably do $15ish shipped once they are ready for prime time.

EDIT 3 BLACK LEFT PLUS THE COLORS

Vague JP info to stay on topic: My Trex now catches the ball 99% of the time after the opto was replaced.
