Quoted from Hazoff:

Whatever the reason I'm glad they don't have faces of the actors all over.....

THIS!

Not a fan of actors all over a game. I appreciate the essence - fighting dinos, saving peeps, etc. Too many movie themes rely on the actors and their crappy monologue imo. In the same concept, while I like the music themed pins, I don’t want to own one for the same reason .... I don’t want to get sick of listening to 30 seconds of the same Metallica/AC-DC/Who/Iron Maiden song - great gameplay though.

Quoted from teekee:

Well if its a bad clear mixture then it a pretty easy fix for Stern... throw out all the remaining playfields and start over. There is no other fix! But again we are all guessing at this point.

They can strip, rescreen and clear an already cut play field. Not as devastating as it sounds but it will take time.

#817 2 years ago

I have a deposit on a JP Premium and I have a question for current owners.....

I’m pretty excited about the complexity of the software, however, I was watching this —>

<—- to get a feel for game play and I’m a little concerned about the number of drains. Specifically the left out-lane eating balls, and a bunch of unforgiving rebounds sdtm.

Is there a left out-lane post that can be closed up a little? And has anyone done any playfield tweaks to make the sdtm drains a little less common?

Quoted from pickleric:

Your distributer ships the game to your house, it arrives, and then you pay!? I want that distributer!

Why is that so unusual? What else do you pay for weeks before you receive it? Real estate doesn’t even work that way.

#1558 2 years ago
Quoted from pickleric:

I didn’t say weeks in advance. I asked if some distributors invoice after the game arrives.

If you’re paying in full now for a prem/LE - that’s at least one week in advance, probably two.

Mine is on delivery or pickup.

Can one of you MOD makers make a wireform connector or a plastic piece that connects the flipper post to this post (see image)?

I think that would take some pressure off that flipper post and provide better longevity.

#1770 2 years ago
Quoted from hawkmoon77:

Interesting. I don't think it'll help to much side-to-side, but it should help more in the up and down. I am going to use a wide shoulder washer (installed underneath) if mine doesn't stay tight. If that doesn't work, I might add a wire-form.

I don’t think side to side impacts are hard enough to matter. But if you want, you could triangulate it with the post on the right loop plastics.

Quoted from jdroc:

Had this happen this morning. I'm pretty sure it was because of this sequence of events:
1. Raptop cage gate open
2. Start chaos MB
3. hit back target on raptop cage
------a. lock post came up then went down (twice actually)
------b. game thought ball was locked in raptor cage
4. chaos MB continued but raptor gate was raised but no ball locked
5. get to 2 balls left in chaos, and chaos MB ends
6. get down to 1 ball left and flippers and lights go dead - game thinks you are out of balls

I just had something similar happen after T-Rex Multiball. Game went back to the standard game mode after TRMulti with 2 balls left in play. Lost one of the two and the game cycles - goes black and dead like after a ball - ball 2 drains and game continues to the subsequent ball if you aren’t on ball 3.

Weird.

#2610 2 years ago
Quoted from Ockeyhead:

Just need to know if anyone has had trouble w/ installing their shaker motor? I ordered a motor from CoinTaker &amp; the motor case doesn't fit over the motor. The coin-box wood piece that separates the coin-box from the shaker motor &amp; the right side cabinet area completely obstructs the case from fitting over the shaker motor itself. Did anyone have a problem w/ this? Also, is your premade shaker drill holes the same as mine?[quoted image]

I got a Stern shaker from my distro and the holes lines up but the cover was a tight fit. It’s pretty soft plastic and took a little push and shove to get it on right. I would trim the cover.

Quoted from wheels:

Anyone install Titan rubbers? What's the best color combination? Please share!

I had orange and green but ended up switching the lanes, flippers, and slings back to rubber. I didn’t like how the ball came off the Titans. Still have the Titans on the posts and upper playfield though.

#2847 2 years ago
Quoted from imagamejunky:

Hey guys.
I've been having problems with my Premium. On almost every game at some point a high speed left orbit shot from the upper flipper isn't registering. Both rollover switches and both optos are working correctly in switch test. My guess is that the left rollover isn't being fully depressed due to the ball speed, or maybe the ball isn't completely flat on the playfield. If it's getting a little airborn it may not be depressing the switch all the way.
I'm just wondering if any of you are seeing this too?
Thanks
Nick

Some shots on my machine aren’t registering either. I just put it all together tonight.... my spinner and left loop (from upper flipper) have had some misses. Going to dive into it this weekend.

If anyone has some insight, please share.

#2863 2 years ago
Quoted from northvibe:

Also the post under the upper flipper fell out. I think this is common? Is this a lock tight thing?[quoted image][quoted image]

As I understand it, the earlier builds did not have a nylock nut on the back of the playfield For the flipper post and people were having problems with them coming loose. The later builds (like my Prem) have the modified post. My HUO hasn’t come loose.

Mine was difficult too. I removed the rubbers and used a small wrench. Turned the wrench 1000 times and finally got it.

#3077 2 years ago
Quoted from Scribbles:

Does the combination of lowering the post and putting the wider star post in almost eliminate right side drains??

Nope - still drains. It’s not as dramatic of a change as you may think.

#3229 1 year ago
Quoted from EaglePin:

I noticed something similar. I might be wrong, but before one of the recent code updates I think every turn of the spinner would register the lane as being hit and clear the lit arrow. Then after an update it seemed like it changed and now a weak shot from the upper part of left flipper that goes past the spinner but maybe only spins it a couple times no longer counts as a shot to clear a lit arrow on that lane.

This is my experience as well (premium).

I got it set up but I have a question... I received a large rectangular sticker with all my stuff... what is that for?

#3315 1 year ago
Quoted from Scribbles:

... I also needed to shim the left side of my shooter ramp. There's a post here on how to do it. Takes 5 minutes.

+1

Just make sure that the left side of the ramp stays below the wood cutout. I only needed a washer under mine to get it to launch perfectly.

#3366 1 year ago
Quoted from WizardsCastle:

Followed one of the T-Rex fix tutorials I found in this thread, and although it helped center the T-Rex, I think the vertical alignment is way off.
Here is a video showing the jaw slamming down on the ramp so much so that the screws are shaking loose.

Is Stern not looking at this stuff before the put a game in a box?
Anyone know what I can do to fix this?

When shooting for the smart missile launch, why would a player choose "abort" from the action button?

IIRC ... there is a cumulative effect on some rewards when you abort.

#4267 1 year ago
Quoted from metallik:

....grind a bit off the rivets so the ball can't hit them. Same with the screw in the tower ramp approach.

I did this to the tower ramp screw. Dremel tool with a fine stone. The ball now clears the ramp without hitting the bottom screw.

#4367 1 year ago
Quoted from Jediturtle:

At least my manual is near perfect.

Mine is the same. I also did the fork fix with the washers but I need to take a peek at some slo-mo on my auto-launch.

Unfortunately auto-plunge kicks in a lot on this game - add-a-ball, ball save, multi-ball - and it is very inconsistent on my game. Wondering if it’s an electronics issue at this point (dying coil)??

#4385 1 year ago
Quoted from per3per3:

I ask because my machine had the updated metal bracket on the left side of the ramp entrance and the black spacers for the roof plastic. I know the older machines didn't have the metal bracket so wasn't sure if this kit just brings the original run machines to mine in terms of how it shipped or if this is truly unrelated.

Try removing the black spacers under the plastic cover at the entrance to the ramp - see if that helps.

#4577 1 year ago
Quoted from SheriffBarclay:

Anybody else get a significant number of rattle rejects on the watchtower shot? It very often goes up the u turn, rattles around, and falls out.

On my premium, the ball was hitting this screw (pic) and caused a lot of rattled shots.

I took painters tape and masked off the left screw of the entrance ramp. Then I took a Dremel with a stone bit and ground the screw head down so that the ball no longer made contact with the screw head.

EDIT: sorry about the landscape - can’t change it.

#4586 1 year ago
Quoted from fooflighter:

I haven't searched yet, but a small flat pan head screw should do the trick aside from a Dremel shave

I found it easier to shave than to replace. It doesn’t take much grinding - check clearances often and take your time.

#4593 1 year ago
Quoted from skogen75:

...and if that wasn’t enough, I just changed the target position so that it is even between the raptor tower and the left orbit. Yours seems to need adjustment too.
[quoted image]

Yep - ordered a few the Pinball Life target kits...

#4618 1 year ago
Quoted from Yesh23:

Has anyone put flat screws on both orbiting ramps instead of the regular screws that come stock? Curious if anyone has done this if it made both smoother?[quoted image]

#4647 1 year ago
Quoted from WizardsCastle:

Anyone know what flat screw would be the proper replacement, and any comments on improvements after grinding down the current screws?

Don’t know what replacement screw would work but I can tell you grinding down the screw (and it isn’t much grinding) made a significant difference in Tower success rates and the general smoothness of the shot. Doesn’t take as much steam to make the turn.

#4700 1 year ago

I had to tweak my TRex a little - adjusted center - adjusted height (loosen mech from behind) - and did the tape trick on the ramp before the revised part became available. Since dialing it in, I haven’t touched it once.

The TRex is one of the best mechs/toys/features in pinball I’ve ever seen. I’ve played a pro and they play fine but that TRex.... it’s a must have imo.

#4764 1 year ago
Quoted from skogen75:

Still getting this game dialed in and I wanted to ask about when the ball is leaving the control room. On mine, if the ball is caught by the up post and released I can usually catch it on the left flipper, but when it’s a fast shot up and comes back with some speed it ends up being a frantic attempt to prevent the ball from draining down the middle.
How does your game play? Should I start bending the ball guide a bit? Game is set to 7 degrees.

I’ve been playing around with a solution to this....

What I’ve found is, the last bend in the ball guide on the control room on mine was a little too sharp. I ended up putting a very narrow piece of painters tape in the crease to soften the transition out of the control room. It worked well and I ended up putting a very small (narrow) bit of mylar in the crease. The ball now travels along the left sling and can easily be caught by the left flipper.

#4778 1 year ago
Quoted from skogen75:

Just to be clear, mylar in the crease of the ball guide itself, not on the play field, correct? Photo when you get a chance? I will try this, thanks.

Tested it with painters tape then used mylar same spot same size piece.

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 caught TRex yesterday and I’m pretty sure the TRex capture awards an extra ball, not “lights extra ball.”

Nice work on the card - definitely printing this out.

PerfectPlay ‘slim’ post sleeves are not tpered.

#5163 1 year ago
Quoted from WizardsCastle:

I also have the ramp opto fix from Stern installed.

Double check that ramp opto piece installation - it looks like it’s misaligned (0:20 in the first video) - that could be causing a lot of your problems.

#5165 1 year ago
Quoted from WizardsCastle:

What do you mean by misaligned? Can you share a photo of yours?

Mine with the upgraded ramp opto piece - sorry about the quality but you get the gist. Yours looks incorrect. I remember it being a little tricky to get new piece on correctly.

#5314 1 year ago
Quoted from kingfishtr:

Really? I thought it was supposed to line up perfectly at the flipper tip with the tiny whole(circle) in the playfield... am I wrong?
[quoted image]

You are wrong - it will go sdtm if the flipper is aligned with the post.... ask me how I know.

#5395 1 year ago
Quoted from fooflighter:

I just put black rubber back on mine after going all around testing different ones....I started with red factory rubber, went to Pinball Life Perfect Play, then Titans, then Superbands, back to red rubber, now after all that, I'm liking the shots with the black rubber the best..
Here's my takeaway after doing about 2 weeks of consistant play with each type of flipper rubber
Black Rubber - best bounce, not too hard, not too soft like red rubber, nice consistancy with shots, best post passing and flipper tricks
Red Rubber - a little too squishy, have softer shot authority, harder to trap up and hit ramps with consistant power, leave red bits all over playfield after 50 plays, get dirty very fast
Perfect Play - slippery, dead bounce, awful
Titans - better than the Perfect play, too much ball slip and still somewhat dead bounce
Superbands - great at first, very hard which made shots really scream up ramps, much harder to control as they add tons of spin and crazy pyhsics to the ball, very hard to predict, makes shots easier but made game much too random and hectic, not fun when trying to progress
I have stuck with Titans for all the rings and posts though and this combination with the black rubber provides the cleanest playfield and the best play overall...I'm really OCD about most things, this was no different

I am of the same opinion in general.

The poly or silicone on the flippers just didn’t do it for me. In the playfield they’re fine - less residue - but I felt it changed the dynamics of the flippers too much. Red rubber on the flippers was my last stop but I too think the black provide a better overall feel than anything else.

Quoted from pin2d:

Hi all, sorry if this has been covered previously...I'm curious about the feed from the Raptor pit area, the "C" shot, the Control Room shot. The end of the ball guide on mine bumps it so it goes closer to down the middle, just curious if it is supposed to play like this or go to the left flipper?
Thanks!

Quoted from DavidPinballWizz:

Just a question for the strategy players here:
Do you always go for the combo:
control room mode + running paddock + chaos multiball?
I'm asking because I do not know the game in detail yet but noticed you can really rack up points with the first combo
I had a 1B single ball only doing that first combo, got a lot of points from amber pops, amber slings, amber targets, ..
Deeper in the game do you strange strategies (for example paddocks towards king of the island, trex modes) for further scoring, collecting fossiles, etc..?

Raptor multi-ball can be huge points when stacked and played well.

INLANE POST NOT STAYING UP FOR SMART MISSILE WHEN T-REX MB STARTS!!!! I mean, um, not that it's been irritating me lately or anything... you know, fix it or not, whatever... I don't care... BUT FIX IT!!!

And the Skill Shot!!

#5658 1 year ago
Quoted from weaverj:

anyone put cliffys on their shooter lane? specifically, anyone know what those two nail/bolt things are to the left. i stripped one. hoping lowe's has some.

I did but I can’t tell you what those fasteners are. Self anchoring screws?? I would imagine they’re in the manual and available at Marco’s or something.

#5663 1 year ago
Quoted from weaverj:

first thing i did was check the manual, but didn't see anything. marco didn't have them either. i'll go into lowe's and look like an idiot. i'm good at that.

Definitely a strange fastener. Call tech at Stern if you strike out at Lowes.

Quoted from WizardsCastle:

Is the truck ball always in the closed/right position when you start your missile shot?

#5830 1 year ago
Quoted from nicoy3k:

Any tips for hitting the tower shot- is this meant to be a tough shot?
I can only hit it consistently off the flipper tip when the ball trickles out of the bumpers but I’m having trouble hitting it off the ramp/loop. I am 7 degree incline.

Check to see if the ball is hitting the screw on the ramp transition. Mine was and I was getting a lot of tower shot rejects. Used a Dremel tool to grind the screw head down a bit so the ball doesn’t hit it anymore.

#5876 1 year ago

Digging the code update but still waiting on a fix for smart missile interrupting the skill shot - frustrates me to no end.

#5878 1 year ago

And this one has been bugging me too....

On both the TRex and Spinsaurous paddocks after 2 rescues the callout is “shoot the set trap targets” when 3 rescues are required to light the targets. It’s the little things.

#5881 1 year ago
Quoted from gblack:

hmm i'll try to see if that happens for me as I feel like last time in Trex it was correct? Have you reported this? Seems like that would have been easy to fix in this code release if they knew about it.
On that note I wish Stern had true release notes with "known issues" to see if we should report things like this or if they are already working on it.

Absolutely sure. And I have not reported it.

It used to confuse me because I’d hear the callout and fire off a quick shot only to realize they weren’t lit.

#5883 1 year ago
Quoted from RC_like_the_cola:

Just tested this manually and after 2 rescues the set trap target do light and after hitting them, the helipad lights.

I guess I need to check my machine.

#6197 1 year ago
Quoted from Stags6969:

Has anyone had issues with the smart missile activating during the skill shot phase?
I've had it happen twice today, when a rescue was sat on the left ramp and it activated smart missile, effectively killing the skill shot sequence.

Yep - it’s happened to me too. I was hoping 1.02 would fix that but no dice.

#6287 1 year ago
Quoted from WizardsCastle:

Here's what's happening 50% of the time with my auto and manual launch:

Your slo-mo isn’t capturing the launch. To properly diagnose the issue you need to see the kicker impact the ball and follow the ball up the guide.

#6288 1 year ago
Quoted from WizardsCastle:

Here's what's happening 50% of the time with my auto and manual launch:

I would also have a look at the right side of that Cliffy and make sure it’s aligned with the groove in the playfield - looks a little too far left.

#6346 1 year ago
Quoted from gorditas:

I'm replacing factory rubber with Titans today. When removing one adjacent to the 2x scoring target, I noticed it was cut. "I'll have to stretch it to keep from cutting the new one myself." Nope. Factory results.
Short of grinding the corner, has anyone had any luck? The original never broke, maybe this will last a while too.
[quoted image]

Nope - I took a dremel and notched and chamfered the ball guide so that it didn’t tear up my rubber. It’s not as bad as it sounds.

#6384 1 year ago
Quoted from WizardsCastle:

Red rubber was even worse. Black improved, but barely. I probably get it across to the right 30% of the time enough to actually catch it.
Rest of the time, it's just a weak-ass pass that I have to immediately flip or it's a drain.
What could be causing this? Anyone?
I'm considering rebuilding the entire flipper, which is insane for a brand new LE game.

Like MrMikeman stated, I think the timing is just different on this game. On mine one side passes easier than the other but with some timing changes I can pass both ways.

#6390 1 year ago
Quoted from RobbyIRL5:

Second T-Rex mode, mine is only catching the ball about 33% of the time when I hit the ramp and when he misses, it’s often SDTM. The first T-Rex mode (multiball) doesn’t have to catch so it starts fine 100% when I hit the ramp (sometimes catches, sometimes doesn’t).
So is this standard behavior or should it catch every time I hit the ramp in the 2nd and 3rd modes?
Maybe his head position is not properly calibrated? I feel like when he does catch it it’s when I hit the right side of the ramp.
Thanks!

Quoted from Multiballmaniac1:

Has anyone’s Jeep Newton ball stopped swinging around freely causing the Newton action to not work. Notice some small pieces of the flipper bushing at the base of Jeep Newton ball mechanism on playfield. Now it gets hung up a little. Not as free swinging. Makes it harder to complete TREX. Any ideas?
Thanks

Quoted from Markharris2000:

Yup. I took a look and can easily tweak the blade to put some space between the time the first set and the second set make contact.
Related topic: mechanical contacts seem like a big step backward versus the opto-set used on other machines. Still a bit surprising, but then again the much lower cost must be driving that choice. An opto set like Williams A-20207 (including LED, Detector, molded plastics, a few resistors, the PCB, connectors, leaf spring and screws) probably costs $2.50 all in for a volume production line. The machanical blade approach and two screws are probably 30-cents or so. To get an idea of their costing structure, I multiple their COST by 10X to get an idea of what the retail price would have to be increased to pay for the parts.

Vinyl or CDs? Solid state or tubes?

Your choice.

I noticed a washer shoot across the playfield and see I'm missing a screw at the Trex ramp.
So I lift the playfield and find this screw in the cab. Can someone confirm this goes there? And if not where do they even use this type?
[quoted image][quoted image]

The screw that is missing in your pic - the right TRex post/ramp screw - on mine it looks exactly like the screw on the left side of the ramp. A dome phillips head with a star ‘lock washer’ on it.

And as seenev mentioned - you’re missing the black spacer that goes under the clear plastic.

#6853 1 year ago
Quoted from Markharris2000:

Two things I suggest when you are ready to install the shaker motor:
1) get some nylon cable tie-wraps and tie the wiring to the existing wires that run from right to left behind the cash box. It will make the installation much cleaner and prevent any tugging on those cables accidently if you pull the cashbox out. I used 5 tie-wraps.
2) get some BLUE thread-lock liquid. Harbor Frieght sells both RED and BLUE for $2 a bottle. Get the BLUE and put a drop on each thread before you screw the four screws into the cabinet mounted T-Nuts. (Blue is the medium strength, semi-permanent type)
Note1: The Premium is pre-drilled and T-Nuts installed, but not very consistently. I would use a small hammer and tap each of the T-Nuts into the cabinet from underneath before you try and install the shaker motor screws from up top. The provided longer screws that go through the cabinet are 'just' long enough if the T-Nuts are tapped in properly.
Note2: The two self-threading hex cap screws that hold the plastic cover on will be a challenge to get installed, but they WILL work! The brackets are somewhat moveable with some pressure, so just stay at it and it will thread with enough energy applied! Get the first one in, and then push/tug/press the cover front to back to front to meet the second hold and press hard when it starts to line up!

Or that...

Quoted from mcvetyty:

Oh man! I get rejected from this shot all the time... Wonder if this is my issue? Can you tell me more about how you ground it down? Did you just sand some of the top off? That didn't impact your ability to get a screwdriver inserted?

I taped the surrounding area with blue painters tape and ground the screw head down with a Dremel and a stone bit. Quick vacuum, peel tape, play - no screw removal necessary.

#6935 1 year ago
Quoted from nicoy3k:

Don’t see why you would risk a dremel slip and tearing up your playfield, removing the screw is tricky but doesn’t require removing anything else from the playfield if you have the right tools and patience.
Just remove the screw and use a dremel or anything else to sand it down as much as you can while maintaining the integrity of the screw. If you mess it up you can always go to the hardware store and buy a new screw
My ball was just fractionally touching so I didn’t do this at first. I was never getting that many rejects but when I finally decided to fix the screw the shot became much smoother.

“Risk”... speak for yourself. I had no problems with it whatsoever. It was easier to leave the screw in place to make sure I removed enough of the screw-head as opposed to removing it, grinding it, screwing it back in, checking clearance, removing it, grinding it, screwing back in, checking clearance.... you got the idea.

Quoted from jlock:

Anyone else have issue of C shot returning SDTM too often? Mine just started doing so and I'm wondering whether there are any fixes short of bending the end of the rail inward.

Take a very thin 1-2mm strip of mylar and stick it directly in the crease of the bend closest to the flippers - the last crease in the ball guide.

On mine the ball was bouncing off the transition crease and going sdtm. Experiment with thin strips of blue painters tape then finalize with mylar cut similarly to the painters tape.

My autolaunches are getting worse to a point it really pisses me off and I do not know how to fix it.

Yesterday I took alot of slomo videos. One big problem is the thin metal flap on the right side of the shooter lane. Its enough send the ball into the opposite direction, leading to massive rattling. However sometimes the ball launches perfectly straight and it still wont make it up the ramp. Any ideas?[quoted image][quoted image]

Looks like it’s bouncing up off the shooter fork. Make sure the washer didn’t raise the fork leg above the wood of the shooter lane.

I tried searching but didn't find anything related to the best path to take using the truck. Any advice? Can you skip the number of paddocks? It seems no matter left or right you'll still have the same number.

You can’t skip paddocks.

The color of the dinos insert reflects the dino’s difficulty. Stay on one edge or the other for an easier pathway to the Visitor Center, or jump in the middle and use the perks for the difficult dinos to help you get a better score.

There is a smart missile reward that will ‘Clear Paddock’ and award you with all the rescues and captured dino for the paddock you are on.

Other than the smart missile reward, it’s grind your way through.

If you hit both flippers soon enough when the paddock is started - essentially canceling/skipping the video - the up post will not come up. The post pauses gameplay while the video plays and explains what’s going on. If you skip it, you also cancel the post.

While you can use either the auto or manual plunger if you want the ball to go up the Heli ramp and into the right return lane, only the manual plunger allows you to short plunge the ball (it doesn't go up the heli ramp) and then go for one of the various secret skill shots
- "C" shot
- the amber target in the pops
- "O" shot
These along with the 2 different combo skills shots gives you lots of different shots to try for when plunging the ball

Short plunging also allows you to not qualify the playfield - especially helpful in Escape Nublar.

Yep - switch to white rubber.

You can go poly or silicone but I don’t like those on anything bigger than 1”. It feels to me like the slings and flippers should be old-school rubber. I like the way the real rubber plays on the lower playfield. That’s how I set my games up.

Two at once is a different issue. Is there anything blocking the trough eject, like a protector edge or anything else slightly in the way? Have you inspected the coil bracket itself to make sure it has not come loose? Have you checked/adjusted the trough eject power setting? It's possible that it tries to eject a ball, and for some reason fails to have enough power to succeed, so it tries again because the shooter lane switch reports no ball present, this time with a second ball that just happens to stay loaded on top of the other, which causes a second eject to be tried... this time pushing both out.
Check the eject coil brackets and power settings. The coil should not move if you grab it by hand and try to move it around. The trough setting should be at least 200-210.

Quoted from craif:

Hi Dinosaur Hunters. I've got a mystery on my hands and I'm hoping you experts can help me out.
I'm not a wizard or anything, but I've got dozens of games on a single JP (Pro) several paddocks deep with lots of extra rescues/side objectives along the way and tons with scores 200mil + and several above 300mil, and yet I've never triggered the raptor multiball. Not once. Nor have I seen anyone else do it. Am I missing something obvious or is something broken on this machine?
The mechanics at this location are able to handle obvious issues like a dead flipper, but for more esoteric stuff they usually need someone who knows how the game is supposed to play to point it out to them. I usually end up being that person, but as I've never played it anywhere else I've got nothing to compare it to.
There are various signs the ball is being detected when it goes into or through the raptor pen. Flashing lights and the sounds of dangling wires and angry dinosaurs. Some games I've sat there blasting it in over and over 20+ times including several hits to the standup and though the dinosaurs are very angry, nothing happens. I know it takes takes multiple shots to bring the fence down but this seems ridiculous. Even if I didn't know it was a thing, it seems like it should have happened randomly by now.
I don't know for certain what code it's on but they updated it pretty recently so I think it's the newest.
Any thoughts on what I'm doing wrong or what thing might be broken given that it does seem to know the ball is in the pen appreciated!

Go into switch test and make sure all the raptor pen switches are working.

* 5 Ball
* Competition
* Director's Cut

Does anyone know what specific features the Extra-Easy to Extra-Hard difficulty levels change? Also, what is Directors Cut, and Novelty? And what does Home Play set?
Through a little searching on these forums I learned that you can "stack" multiple of these installs. (For example 5-Ball and Extra-Easy). And if there are settings in common, the last installed takes precedence.

Usually the ‘easy’ settings spot shots (start with 2 of the 3 map lights lit) and require less shots to complete modes as well as longer mode timers and ball savers. There’s usually a description in the manual of what the selection does.

Best way to find out what they do is select one and play it. Easy enough to set back if you don’t like it.

Any thoughts on where to start on this man made issue? I can take pics if needed.

1 - Look in the key posts on the JP Premium thread - lots of TRex adjustment info there. In a nutshell, you’re going to have to loosen the TRex mech from the back and adjust it down from there. Not difficult.

So I'm sending my stepper motor driver board and T-Rex assembly with stepper motor back to stern for troubleshooting repair as it's not moving at all horizontally.
I'm almost positive if it's anything it's the driver board as the bipolar motor windings look good ohms rating is holding constant at around 9.7 ohms on each coil
Took out the stepper board and flipped it over and found this on the back side of the 48 volt input to the board and also the capacitor... When plugged into the system it's showing 48 volts on a multimeter and no really clear way of testing the capacitor other than starting out at one value and going to Infinity when the probes are placed on it aside from desoldering it from the board...
So what does this look like to you? is this just some sort of soldering residue or could this be the result of a flash spark that shot through the pcb from a 48 volt over current short?
Thanks all for looking
[quoted image][quoted image][quoted image]

It’s either solvent from flux removal (should only have been alcohol) and not likely to cause a failure.

Or it’s a fried solder run under the laminate. My guess is something on the 48v line shorted (capacitor?? Though that cap looks pretty good) and fried that run.
