Quoted from NoSkills:

If I remove this nut holding the raptor foot, will the bolt fall down or is it on a post?

Quoted from SimplePin:

Essential tool used for all nut, screw, washer etc removal. Remove with confidence.

Quoted from NoSkills:

I have a magnetic tool but I was more worried about screwing it back in, looks like I’d have to take off a lot of plastics to put the bolt back if it’s not a post

Quoted from SimplePin:

Page 52 of the manual. There are nuts under the plastic on each foot. Not sure what you are trying to do but probably safer to remove the whole top with the Raptor attached. Actually taking a closer look it looks like yours were installed opposite of what the manual shows. Mine looks like yours.

Quoted from NoSkills:

Thanks, guess I’ve got some dismantling to do!

Quoted from Pin_Fandango:

is the raptor not entered and it is getting caught when it bends over?
use an air dryer on the arms, heat them up until the are flexible (do not burn anything, just heat them up), hold with your hand until it cools down in the desired position. The part is now fixed in that position and the raptors arms will no longer touch the plastic on the side.

Quoted from Pin_Fandango:

I have the round screws in my game and the ball is miles away from it, it will never be in contact with the screw head.
I am here to debunk the screw myth really, because if the ball is touching the screw head in your game there is something else that is wrong with your guides allowing the ball to be closer to the screw...

Quoted from 1956PINHEAD:

troon47 this system when installed will recover the lost energy inherent in the flipper mechanism. Just how much may vary depending upon how many cycles are on your coils, sleeves, and stops.
The improvement on my Godzilla was noticeable as well as on my AIQ, especially when shooting the Captain Marvel loop. Feedback I've received from others who have installed the mod have also noticed an improvement.
This system improves the stability of the flipper system improving shot accuracy as well, it essentially removes 98% of the slop/play in the mechanism which translates into better ball control when going for those tight shots.

Quoted from athomepinsider:

Hey all, I just took delivery of my very first pinball machine today. A NIB JP Premium. I'm a big Jurassic Park fan, always have been. I got this sucker in the house all by myself. Thankfully, no cosmetic issues to be seen. Playfield looks good, zero pooling issues. Newbie ownership question, but a couple of things I noticed right away, hopefully going through the adjustments options can fix:
1) My T-Rex multi-ball only lets 1 extra ball loose. From what I remember at the arcades I've played at it's suppose to be 4? Possible there's an adjustment to be made in the menu?
2) Concerns the Raptor gate. When I hit in there 3 times and activate the locking mechanism, and the mode activates, the locking mechanism will fall as it's suppose to I believe, but then the gate is popping back up, keeping the ball in there, and will remain until my ball drains. Only then will the gate open and drain as the ball is over with. Another adjustment to be made in the menu?
Thanks all,
Will

Quoted from SimplePin:

Welcome! T-Rex multi-ball is a 2 ball mode. More balls can be added via supply drop possibly. On the Raptor gate. First hit drops it. Some number of shots sets up capture. Once the first ball is captured (up post up, gate goes up, up post down) then you need to hit the gate some number of shots to open the gate to start Raptor Tri-ball. The gate shouldn't open and let the ball fall without starting Tri-ball or draining your last ball. Hope this helps.

Thanks for having me! And huh, well looks like I have a bad memory about the T-Rex multi-ball. And you're right about the raptor gate too! Thank you for explaining that! I got lots of learning to do about this pin! Man, I can't believe I have a pinball machine in my work office
So many modifications to look into as well. Time to get reading through the pages for ideas. I think I've seen someone around here have it - a goat chained up in front of the T-Rex. That would definitely be one of my first go-to's. Ah the fun begins...

Quoted from EaglePin:

Huge majority % of flipper fade (lost energy) caused by playing for long periods of time is due to the coil heating. Have you measured the coil temps with stock parts vs coil temps with your parts for extended sessions (60-90 minutes)?

Quoted from BallyKISS1978:

Going through the threads looking for an answer. Question for premium owners. Do you have issues with the T. rex not holding the pinball in its mouth when the pinball goes inside it?
Found the post about adjusting it and checking if it’s aligned correctly. Anything you have done to fix it, or is it one of those things that just happens.
I just got my premium NIB this month.

Quoted from EaglePin:

Debunking your debunk. It definitely has been an issue on some builds where the screw heads are placed differently and contact the ball. Not anything really to do with the ball guides, just how the flaps & screws are put in on some assemblies with screws not put in quite close enough to the guides. Likely just an issue of inconsistency with a manual build process.
There have been posts in this thread about it going back at least 2 years.

It's not made up or mis-diagnosed. Just because it isn't an issue on yours (or mine) doesn't mean it doesn't exist.

Quoted from Had:

Mr_Tantrum
Thank you for your post #8114, this has to be one of my favourite JP mods.
I wired mine to the helipad.

Quoted from Salami_Inferno:

Link?

Quoted from RTS:

On occasion, a clean shot to the left T-Rex ramp hits an invisible force-field and comes rebounding back down the ramp. There is nothing visible for the ball to make contact.
I assumed it was an airball hitting the front edge of the plastic protector way at the upper back end of the ramp (before the ball would go out of view). I increased the spacer to allow more vertical height in case the ball was flying into that protector. It's still an inconsistent occurrence, but the ball is definitely abruptly hitting something.
Just curious if this has happened to others, and if there is a known resolution.
Full Disclosure: I have the Lior T-Rex installed.

Quoted from Manny65:

In switch test mode check that the opto switch in T-Rex's mouth is working.
Not sure off the top of my head if there's also a magnet test, but look for it to verify that the magnet in the mouth is working (ie can hold the ball)

Quoted from SimplePin:

This happens occasionally on my May 30, 2022 build Premium. Stock T-Rex head. Your description is spot on. Force field activated!

thank you. I will check. Sometimes it works and other time it doesn’t. Will check now. Appreciate your help.

Quoted from scurker:

I'm considering getting a shaker motor eventually, does it integrate well here?

Quoted from athomepinsider:

New owner here again. Is it normal for my glass to be extremely difficult to slide out? It takes all of my strength and my weight against the cabinet to get it to slide out. My ball has gotten stuck on the up post while is still underneath the playfield, like it's magnetized or something. This has happened a couple times now.

Here are his chopper, chopper part two, and jeep install instructions. All of them should be made key posts, IMO, for any of you that have that power:

Quoted from sidesmack40:

Another question. Any rumor of a code update in the near future? I see JP premium just went back on the production line from sterns FB post.

Quoted from pinheadpierre:

For those seeking a helicopter mod, the Matchbox Quetzal-copter is still available from numerous sources. Installation requires basically the same steps as outlined in Mr_tantrum’s excellent directions. I put a few small pieces of heavy duty Velcro under it between the screw heads for the helipad plastic to keep it from jiggling around.[quoted image][quoted image][quoted image]

Quoted from sidesmack40:

Thank you I found and ordered this! It’s not going to have the spinning blades but that’s ok.

Quoted from Pin_Fandango:

I am here to debunk the screw myth really, because if the ball is touching the screw head in your game there is something else that is wrong with your guides allowing the ball to be closer to the screw...
Please correct me if I am wrong. Perhaps this was an issue in earlier runs?
On that note I see how adding a washer at the plunger fork might help stabilize the ball by keeping it in the middle of the shooter lane rather than making it depend on speed to balance it... This I need to correct in my game however the screws used in both chopper and tower are perfectly fine in mine.
Here is pic to demonstrate.
Something to note, I used a flash light BEHIND the ball to see how much 'air' there is in in between the ball and the screw head. If you are not doing this and you are going by 'feel' what you are feeling might the ball rubbing in between the transition in the PF and the mylar as the ball rolls on and off the edge of the mylar, which happens to be right next to the screw, giving you the false feeling you are touching the screw.
ymmv.
Good luck[quoted image]

Quoted from Mr_Tantrum:

Here's my "mod of the day" . . .
Orange illuminated sling star posts - because you can never have too much orange. Unfortunately, the camera is having a hard time capturing the orange light well.
[quoted image][quoted image]
For those interested, here is how you do it:
Parts List:
2 x Orange star posts (from your vendor of choice - Titan, Pinball Life, Marcos, etc.)
2 x Comet sunlight white Matrix star post LEDs
2 x Comet 6" Matrix extensions
2 x Comet Matrix alligator clips
Optionally, you can add Comet Matrix brightness adjusters if you want to tone the brightness down a little.
[quoted image]
Turn off the pin (you can leave the balls in).
Remove the right sling plastic assembly by removing the screw securing the right wireframe (next to the helicopter pad), the nut securing the wireframe to the sling, and the small nut at the base of the sling plastic. Repeat same process for left sling by removing the left wireframe screw by the raptor pit, the nut securing the wireframe to the sling, and the nut at the base of the sling plastic. Now you should have both sling areas fully exposed. Go ahead and remove the rings at this point.
[quoted image]
Remove the long screws securing each of the clear star posts. Attach the 6" extensions to the post LEDs and feed the wire down through the adjacent hole on left and right sides. On one side, insert post screw through orange post and LED, position on playfield you you like it, then tighten the post screw. Repeat for other side, and reinstall the rings.
[quoted image]
Lift and extend playfield resting it where the rubber feet are on the lockbar rail. From the underside of the playfield, find each of the wires you fed from the top, attach a set of alligator clips to the wires. Pull down the shrink wrap on the lower sling LED socket leads then affix the alligator clips (not sure if polarity matters, but I put red on red wire and black on other). Do this for both sides.
[quoted image]
Before putting everything back together, close coin door if open, and turn the pin on to see if everything works. If not, check your wiring and make sure your alligator clips are making contact to the metal leads on the lamp sockets (make sure they are touching nothing else).
When tested, turn off pin, put playfield back in place, install glass, turn on pin and enjoy!
