Got my machine today. No issues out of the box that I could find. After about 20 games though the trex has gained a noticeable louder movement noise almost a grind on the left right movement. I’ve inspected the wiring and nothing is catching, up and down is quiet. I can’t see any loose hardware. Looking for suggestions.

Also any tips on the raptor gate, sometimes it comes up and traps e ball when I get it behind the captive post and it’s held, other times the ball is held and then the gate doesn’t raise and the ball is released..
Any assistance is appreciated. Thankyou

#4359 10 months ago

On the latest code. Seems that the raptor gate is catching somehow in the down position and then not moving up. I can’t see how to adjust its position other than the Playfield height

raptor gate corrected, needed a minor move forward. its still very close at the back compared to the front, but its reliably working now, no binding . currently my game is at 6.5 degrees at the flippers, debating whether i should increase it to 7. C and S shots are quite difficult, with the C shot often dribbling out and hitting the top of the sling. release from control room seems to miss the sling 80% of the time. Level left to right

#4403 10 months ago

Anyone had their trex head hit the gate plastics on the left and the cabinet side? my wife thinks the rex hit the side of the cab when thrashing this afternoon. there is a small ark on her side and the cabinet, not sure how its been possible.

#4405 10 months ago

Theres a left limit adjustment, but i haven't played enough with it to know if it affects it. the bias + and - can be confusing to set.

#4426 10 months ago

Annoyingly my raptor gate issue is back after I thought I had it fixed. I may have to go down the path of enlarging the holes in the metal bracket to give some adjustment space. Disappointed.

Looked at the bracket mounting to the Playfield and it was 1-2mm bent. Likely leaned on during install meaning the gate wasn’t perpendicular to Playfield. Minor gentle push to get back straight and hopefully it should be sorted.

#4428 10 months ago

Still debugging my trex. It will move laterally (left right) if touched gently when homes in the center. Potential slack in the gearing? Left position contacts the left post and left thrash extension comes Very close to the cabinet side, right extension is always over the ramp return as I expect.

the rear of the jaw contacts the back of the ramp when lowered. To me this means it needs vertical adjustment, but am wondering about the horizontal. Should it be stiff without any slack?

#4494 10 months ago

Any thoughts as to where this thumb screw should be? Found in back of bottom cabinet. Also lost a small black screw somewhere topside that I can’t find where it goes. I’ve checked all the raptor plastics and signs which have similar

#4496 10 months ago

Found where the screw came from. Trex lost her jaw. Ive replaced the missing jaw screw, found a 2nd but haven't yet found the 3rd.. very very annoying on quality control

And yes them screw is from coin door.

#4497 10 months ago

Should there be 3 screws holding the trex jaw on? I only have one, there’s space for 3 and I’ve found another loose screw the same size in the coin trough

Quoted from ShineSpark:

Hi guys,
So Teddy my T-Rex's jaw fell off and I can only find the two screws. I've gone through earlier posts and it seems as though this has happened to a few people. I can't find the third screw. As per the picture, the two screws here I think both come from the two side holes near the back of the jaw. One was still in the jaw (side) when I pulled it off the playfield and the opposite side and the front middle hole were empty. I found a screw in the cabinet that is identical to the one which remained in the jaw so I'm presuming I am missing the screw for the middle front hole.

They are all the same size and are listed in the manual. SCREW, 4-40 X 1/4" PPH MS BLACK.
I still haven't found my 3rd missing screw from my jaw loss either, but im sure it'll be somewhere. I have an audible thunk/rattle every time the ball hits something in the machine. its either the playfield moving a little (unlikely) or something rattling somewhere i haven't found yet

I’ve adjusted the left position bias on my trex but she still gets extremely close to the left side wall and moved the fence post when rampaging. Does anyone have any other suggestions?

Mine is rubbing also and I can’t fix it with left bias adjustment

#5038 7 months ago

Any tips on removing and replacing the helicopter mech? I took mine off today to change the rubbers and I had a real struggle getting it back together. Had to find a way to hold the underside post near the opto to tighten the blades.

Quoted from Ryeryerulz:T-Rex issues after the code update.
Game was playing great, NIB with 350 plays so far and after the update (might be a coincidence) the T-rex has rendered the park closed.
When entering a T-rex encounter or T-rex chase, the ball does not get picked up by the T-rex, it gets spit out and the ball rolls back into the play field and the shot doesn't register. It works to acquire the T-rex multi-ball and plays well through that, but when the T-rex stops working during a T-rex encounter or chase you cannot hit the T-rex ramp or start another paddock.
It still does not pick it up for T-rex multi-ball but it did trigger the m-b. We are brand new to Pins and are a bit overwhelmed with the adjustments and the options available to run diagnostics. Not really even sure how to run the diag. We tried, but are not even sure we know what we are doing.
Help from the community. Thanks.
PS. We just added the shaker motor this morning also, but it was doing this before the install.

My trex seems to have the same selective grabbing dependent on the mode start. The Trex chase it doesn't enjoy catching to start that mode but does fine in others. my shots also always register on the left ramp

#5083 7 months ago

Yeah I have no audits and tried to figure out why, perhaps this is the issue . Code bug?

Heli on the helipad....
Took this idea from someone with the pro. But even with the spinner blades it looks cool.[quoted image][quoted image]

very very nice. I’ve drilled a Coptic to do the same but I don’t hav the correct colour scheme on mine so it’ll need a repaint. Correct copy or is available but I’m not paying $45 shipping from the us or uk to Australia for a $5 toy

Does anyone have these Pingraffix pin blades on their machine? https://www.pingraffix.com/product-page/stern-jurassic-park-pinblades
I’m getting my JP Premium today and will probably buy some pin blades soon. These seem like they would be a good match for the game art at the back of the machine with the blue. I’ve seen one or two other art blades though so would be interested in any feedback and opinions.

Happened to me also; I just blue "locktite"'d and its been fine since. I still haven't found one of the screws though.

My s shot return has always returned over to the left sling. I’ve seen in streams that for many it lands squarely on the left flipper. Is this the intended? With standard rubbers and Titans it’s always left sling for me

#6164 34 days ago

It’s at 7. I think I need to move the guide out a little so it gets less deflection from the rubber. My left control room shot also hits the sling occassionally on its return so maybe I should go a little steeper

#6174 33 days ago
Quoted from Manny65:

Mine 95% lands on the left flipper - the ball comes down along the ball guide and then clips the rubber ring below the ball guide, deflecting the ball across to the left flipper. The other 5% the ball is much slower and runs down the front of the rubber ring ending up on the right flipper (maybe these aren't rolling out of the S shot on the ball guide).
What PF pitch do you have your machine setup at? Raising it slightly might help (Keith indicated that the game was designed for 7%)
Alternatively can you loosen and bring the ball guide marginally forward so that the ball doesn't clip the rubber ring as much (ie reduce the deflection)

I’ve moved the rail out as far as I can and still be able to get the screw back into its hole. My rail is just behind the line on the artwork at the tip of the rail, you can see the black outline edge; but I still hit the left sling. I have no more adjustment to go and it’s definitely at 7 degrees

#6177 33 days ago
Quoted from Manny65:

This is where my ball guide sits for comparison
[quoted image]

So close. Maybe I can play with slope more. It’s really annoying me now that I know that almost all return to leftflipper as I’d expected. At short plunge will goto the sling for me

Ball search isn’t going to find this magic spin ball. Bounced up from a hard pop bumper hit on the chaos shot and just spun there

#6358 16 days ago

Playfield is just under 7 at the flippers. The ball did come down the ramp by itself eventually. Possibly a little magnetised but unlikely. The ball didn’t actually come from down the ramp but rather landed onto the mid point from the pop bumper richochet
