Yep common problem. You don't need to remove the one way gate, just raise the left hand side marginally up (the circled end of the bracket should be just above the top of the ball guide). There is no need to loosen where the bracket attaches on the right side, as there is enough flex in the bracket to lift it the 1-2mms you need.

Manny65 Thanks for the tip, I’ll try that and see if that works.

Update: This did fix my problem, ball didn’t get stuck at all during the last 20 games or so.

Just thought I'd chime in briefly with a tip for fellow owners (I have a JP Pro).

If you find yourself getting annoyed from having T-Rex Multiball hurryup starting before you're ready to play the mode (due to it starting as soon as you complete T-REX via the truck, which can easily be done by mistake during another objective), you can change a setting so that all T-Rex modes must be started via the Left Ramp, including TRM.

This setting both prevents the multiball hurryup from starting before you're ready, but it also makes the first T-Rex mode random (changeable via the truck) which also helps add a bit more variation to each game which is nice, instead of TRM aways being first and the others random after that.

I forget the exact setting number, sorry, but it shouldn't be hard to find.

I am the proud owner of a limited edition and absolutely love this game. There’s a few issues with it though. It hasn’t really been played much so this was kind of dissapointing;

- speaker pops loudly every 10 minutes or so.. checked the wiring, looks mint...
- trex wont eat ball (tried the optic fix, didn’t work, seems the magnet doesnt activate though I wouldnt exclude vertical alignment. I kind of find it difficult how to adjust that from the instructions on here.. is there a video somewhere I’ve missed?
- the supply drop target and some other targets are really tilted/bend to the left I’m not sure how to fix this, checked the bottom of the playfield there’s mostly 2 screws keeping the targets, but I dont see an obvious way to adjust/make the angle 90 degrees
- after the ball drops from the right ramp loop it bounces of the side a lot of the time, missing the upper flipper and draining often.. this might be fixed by more precise horizontal levelling, although it seems pretty straight..

Had the same issue. My wireramp came out way to high. The ball even touched the top of the side rail. I finally bended the wire back so it would feed the upper flipper nicely. Now I can make the tower shot easily.

Loosen the screws for the targets and move them my hand where you like them then retighten , they were probably not as tight as they could have been and moved a little...should fix the issue

Unscrew and rescrew the helix ramp and give a slight pull towards the guide rail, keep doing this with test ball drops at different speeds until you get a nice location that works...mine started off bouncy when i got it but dialing it in rolls off the helix perfectly every time, you just have to play with what works for your machine

can't help on the other two issues

Hello all - just got my first pinball machine - Jurassic park pro NIB and have been looking around the forum for upgrades/mods/maintenance ideas and came up with:
Shaker motor
Art blades
Replacement balls (although it looks like not too many have any premium balls in stock)
Wax

Any other recommendations? This seems like an awesome community!

Welcome! Shaker motor is a must IMO. There are some really good looking raptor tower mods to consider

Capture Spinosaurus and play King of the Island MB

Ha!

A combination of a shaker motor and the Pinwoofer super kit really brings the game to life (if you live in an apartment and play at night, you'll meet the neighbors pretty quickly).

Fixing the target their angles was easy and effective, thanks!

The helix ramp seems no issue after I re-leveled the entire table (wooden floor, so I guess it gets inaccurate pretty easily).

I still require two ideas for the remaining issues;

- how do I check the trex magnet, and how do I adjust the trex vertical position (I dont understand the instruction with the bolts, perhaps someone can explain in more detail or point me to a video?)
- speaker pops loudly now and then.. checked the wiring didnt see any issues, resetted the audio settings to no avail

Thanks!

Are you sure it’s not the credit knocker you are describing? It’s loud and annoying. You can turn it off in the settings.

This is why I installed a real knocker in mine. Alas. It’s louder and Even MORE annoying. Lol

Why don't you just suck like I do? My games are never annoying like that. Ever.

For those having issues with the T-rex capture, make sure your wiring harness isn't resting between the backboard and the mechs motor. I had this happen to me and it wasn't allowing the lower jaw to rest flush with the ramp.

You can also adjust the default T-rex positions in the menu, check feature settings. Try adjusting the vertical bias if your ball is not capturing. I had to adjust mine two clicks to the left. One of the coin door buttons activates the jaw during this adjustment for better accuracy. Just make sure you are holding down the coin door interlock switch when running the test.

I believe the magnet test is also in feature settings. You can take a ball hold it in the mouth of the T-rex and then hit the test button. Should have a distinct, firm grab of the ball if working properly.

This game is the gift that keeps on giving. Since owning this machine back in October, I’ve finally kicked about 85-90% of its ass - haha! The other night I put up this score by collecting every single fossil in the game to complete all the sets (worth 500 mil + each set’s rewards), captured 6 or 7 dino’s I believe, beat VC and MM, but missed a couple shots on SCR. Made it to EN and escaped successfully but did not qualify WDRTE because I didn’t finished SCR Nearly there KME! Nearly there! haha.

hot !

That score's insane! Congrats thescottiep - how long was the game??

How long was which of the 10 games it took to get that score? Oh wait...that's just how many it would take me to get to 6B.

Congrats - that's an impressive feat!

Manny65 It was easily over a hour! My mom wanted to play two players and she decided to go play ACNH after seeing me play for longer than 10 minutes. She came back and was like “Oh, are you done now?” lmao!! // jdroc Thank you!! Some key pointers: Pteranodon Attack can be HUGE (e.g. capture the Pteranodon for the additional 10x reward and keep building that multiplier before cashing out) - Try to get at least 50/60 mil for that wildcard fossil!), Make sure to save VC for last - that way you can maximize your fossil count and combos prior to cashing those in, and one solid raptor MB may be all you need to get close to breaking 1bil by itself. 2x PF (+ 1 ball relocked) = 4x + (x5/x6 from balls in play for stage 3) — a 20 or 24x Super Jackpot on this can be mind boggling!

Cheers!

Man thats an amazing score - nice job

Time to put mine on 10 balls...

I put mine on 11 balls and still can’t get a million

You can also pull out the interlock switch which sets it to "door closed" mode

Hey everyone, I am going to be picking up a pro in a few hours. Any watch outs that I should look for before purchasing?

Also, I see on the pinball vehicle hauling thread that it should fit in my Equinox, but I’m wondering how hard it is to take the backbox off if I need to. Anyone have any idea? Thanks everyone!

I joined the club!

Decided to go with the Pro model. I was on the fence for months trying to decide between the Pro and LE model and after reading all of the discussions about Premium/LE issues,etc. it pushed me towards a Pro. I really do not miss the moving T-Rex and the raptor gate is cool on Premium/LE but feel I am not missing much without it. This game is a masterpiece when it comes to layout and flow. So many great shots that are as smooth as butter. Also the sound and music quality is excellent, it is the best sound package since Star Wars. I am loving JP Pro!

It should fit easily into an Equinox. Move the back seat as forward as you can

Thanks for the response! I read about certain years being problematic. Mine is a 2019 and I saw this about a 2019 that has me worried.

Do you have any sterns at home to measure against your rear entry height? I’m not at home to measure

I think the height with backbox down is 29-29.5

I don’t have any unfortunately. It’s all good, I’m just going to swing over and borrow a truck from my dad to be safe. Thanks for the help dude!

Anytime!

I don't understand how you guys get these fossils. I'm a decent player, and I've been one shot away from EN, and had only one fossil. 90% of my games, I don't even collect one!

Fossils can easily be collected from beating Trex modes and Control Room modes fully. In addition, there are hidden fossils that can be collected (e.g., smart missile award and raptor MB stage 3 Super Jackpot). If all else fails, if you cradle up during play to view more info, there is a screen that shows you how to gain wildcard fossils which will basically fill in for missing fossils (e.g., 2/3 - 1 more fossil needed to complete a set). Some of these wild card fossils include (x amount of loops, x amount of raptor tower shots, >50mil Pteranodon Attack Collect, etc.) Generally, I find that I naturally collect those first two wild card fossils mentioned by time I get to VC and headed toward EN naturally. Hope this helps!

I wish the Control Room modes would save progress so that you can go back and finish them up on subsequent visits to the control room.

I’m a decent player and terrible at the fossils as well.

I have both. JP has better shot layout , more flippers, more fun. Better game

Metallica is a fun game, no doubt, but it has a very vanilla layout and the rules get really wood-choppy as you get deep into it heading towards EOTL. JP is 100% unique in both layout and ruleset. I loved Metallica intensely for the couple years I owned it, but do not miss it much, especially since I can play it at a number of other places. That's enough for me now. There is really no comparison...JP blows it away.

I've owned the pro for coming up on 2 months now and to be honest I'm missing the moving T-Rex... the pro won't let you skip the animation that I assume is accounting for the T-Rex movement unless you've got that paired with a paddock... otherwise you're stuck watching it every time... if I'm going to watch it I might as well watch the dinosaur throw the ball around. I've also been shooting the Raptor pen for 2 months now and it has to be more fun to bash a gate then shoot the targets. I don't regret my decision one bit but if someone walked a Premium in front of me and asked for $1K-$1.5K(CDN) more than I paid for my pro I'd go Premium... of course that world doesn't exist so Pro it is!

I've owned both, had MET for a year (Which is long for me), more variety in JP, tougher shots... I love inline drops though and the Snake and Sparkey are really fun to shoot. The art is fantastic on MET as well. If I had to make the choice today I'd go JP.

I own both, COMPLETELY different games. Metallica has much better flow to it, jp has better shots, more unique, deeper , etc. As odd as it sounds Metallica is a better family game. Both are fantastic, but it truly comes down to what kind of game you are looking for. The flow on Metallica is amazing, where Jurassic park is more clunky in terms of flow. Not saying that’s a bad thing, and I’m happy to have both, since they are incredibly different.

Finally got mine all setup - now if only I could play better!

Looking good. BTW, my 8 year old daughter just beat me 3 of 4 games. At least she is learning to count to 100 million. Haha. ( not quite to a billion yet).

hello everyone, I have a problem with my t-rex on my premium, the head goes up and down without stopping. impossible to operate. if I restart a game, it's the same it goes up and down without stopping before even launching the first ball. do you have any advice for me? Thx.

Save VC for last?? I’ve only been there a handful of times haha. If it’s ready, I’m hitting it.

Just joined, waited a few for most of the bugs to be worked out.

Nice! Looks like the rumor that games are on the line at Stern again is true.

damn! April 15 is a good sign..

A very minor, but honestly refreshing thing I suddenly noticed while playing Jurassic Park yesterday: It doesn't have any kind of shifting lane lights with the flipper buttons. It's not a big deal, but just like video modes to me are a distraction from what pinball is, I kinda feel the same about lane changing, at least now that I noticed how it feels when it's not there.

Given the above, it's no wonder it was voted game of the year!

That's a good observation, surely it can't be the only modern stern to not have that feature. Haven't played IMDN in a while do you switch anything with the flippers on that game? Maybe it's an Elwin thing?
