Quoted from javagrind888:

So unlike some others on here, my auto launcher was shooting around the loop 100%. I then put Titan bands on all the flippers and now it hits the little flipper and only succeeds about 75% of the time. Are Titan bands thicker than the black bands that came with the game or is it more likely that I moved the positioning on the flipper? I'm thinking about swapping the single flipper back, but it was a bug bear to get on and the color will be off from the others.

That's pretty strange. I'd say you more likely moved the PF. You'd be talking 1mm max difference, and your ball would have been hitting it way more if it was only missing by 1mm. Try cleaning the PF. When mine starts screwing up, a good cleaning fixes my issues.

OK. After this fix, I went 50 for 50 on the auto plunge and had two perfect games with the auto fire working the way it was designed. I've tried every fix mentioned here and spent dozens of hours tweaking this.
Here's what (for now) finally worked.

Make sure your playfield is level.
Make sure both your auto fire prongs are touching the ball "at rest" and at the end of its cycle.
Clean and wax your playfield prior to adjustments.
MAKE ALL ADJUSTMENTS WITH YOUR LOCKDOWN BAR ON AND LATCHED.
Trust me on this one. Bar on and off produces different results.

1. I loosed the nut under the playfield that holds the top of the rail down.
2. I loosened the hex nut that adjusts the rail.
3. I inserted a plastic wedge to (slightly) move the rail more towards the playfield.
4. I adjusted the angle of the ball's trajectory with the wedge.
Pushing the wedge (down) towards the player moved the trajectory up towards the left mini flipper, while moving the wedge (up) away from the player moved the trajectory towards the rubber post.
5. After final adjustments, i'd say both screws on my machine are not loose, but they're also not snug. Tightening the nut under the playfield AND the hex screw at the end of the rail tight (like you'd expect) returned the game to erratic auto firing.
6. My final adjustments were with the wedge. I spent two hours yesterday and three hours today coming up with this "why does this work" fix.

If you're having problems, give it a try. Hopefully it'll work for you too.

Anyone ever have the problem where the game automatically chooses a song and the tomb opens at the start of the game?

#1454 1 year ago
Quoted from splitcms:

Mummy newton is gapped too close mostl likely. Vibrations are actuating it twice quick and opening the tomb. This would pick your song and eliminate all skill shots. Newton may be sticking as well. Check the mech.

The rubber sleeve on my Trooper MB diverter post creeps up every 10 games or so, resulting in stuck balls and annoying searches/tilts from trying to free the ball. Anyone else having this problem? I've had MANY games with posts and never had this happen. Before I contact Chas, wanted to see if there are any solutions folks have been implementing.

Thanks,

this doesn't happen on mine, but I'm assuming it must be catching on the hole a tiny bit. You may be able to just readjust the post and center it better

Thanks for the tip/response. That's what I was thinking as well. No adjustment to center the post, but I bent the bracket and seemed to improve it. The mech does have an adjustment for the post height. I raised it 1/8", so the ball is unable to rest in the hole (which it was doing, ever so slightly).

Man, this game is temperamental....

good! Much easier fix than the damn auto-fire.

Yep...fortunately, the auto-fire works great on my example. My only remaining issue is my mummy captive ball is still wonky. I replaced the armature & adjusted the switch, but the ball itself seems to catch (which requires hitting it to reset).

Ooh that does suck. Mine is having an issue with balls repeatedly getting trapped while the sarcophagus lock is moving. This has happened about 8 times now. I immediately pull the glass so nothing bad happens but it is hard with that lock bar.

Had this issue, found an easy fix.

Remove the rubber from the metal post, place some electrical tape on the metal, re-attach rubber with a nice snug fit. Make sure that you don't invert the rubber, it is tapered and will cause problems if changed.

Great idea. I've solved a lot of problems with electrical tape over the years, but it didn't occur to me for this issue. Thanks!

If the newton ball isn't centering properly, unscrew the spring retaining collar (8) slightly. Loosen (4) first and start with about 1/2 turn on (8).

Thanks for the tip. Man, getting ahold of the newton ball to adjust (8) is a PITA. For me, loosening it seemed to make it a bit worse. I was able to tighten it a bit and it's working pretty well. It was never awful, but does seem dialed in. Considering the mech, I imagine 98% success is good enough

Thanks Rob,

I must reiterate, please all, excuse me for continuosly going on about this junk mech.

take a look at the exploded view provided from Rob , simply unacceptable in today's day and age

Just a huge waste of materials added to the BoM, Additionally the wasted labor required for assembly,

What happened to the proximity sensors ? even the simple NB ass'y from Met is way better.

The worst part is the headaches this mech is causing owners and distributors.

As a pinball tech at a technical level, there is NO way this mech can be reliable !

I never want to see this rubbish again, you are better than this Stern Pinball.

There has never been a worse newton ball.

I ask Stern to come up with a proper solution.

No reason to excuse you RA because you're speaking the truth. It is a poor design plain and simple. Its not a question of if its going to need worked on and adjusted, its when. Stern knew it was a bad design before it ever left the factory, thats what pisses me off more than anything about it.

Truth! Every time I fiddle with this mech it's frustrating. I've owned 40-50 machines and have fixed/tweaked a lot of mechs and this is among the worst (the most arcane/complex/ornate implementation of a simple feature). I realize Keith was the new guy on the block, but you'd think Stern would have given him the "A team" to polish the Premium/LE (since the design of the game was largely accomplished outside Stern).

Do you think there is ANY chance Stern comes up with a proper solution? That would be great, but out of character for them...

It was the mechanical engineer’s first pinball project as well.

Agree this is going to be an ongoing problem. You simply couldn’t consider routing a prem or le of this game with these mechs.

Mine have been pretty good but considering the relatively low plays my game gets vs a routed game...

Pray it doesn't get a Game of Thrones-type fix for mechanical issues - just disable the feature and call it "as designed."

I think you are really on to something here. This has also helped by auto plunger success....(inserting a wedge)

Nice. I'm happy to announce 100% accuracy for the auto fire since this tweak. I've put on about 50 games since my last post, and well dammit, it still works.

#1478 1 year ago

So I should have not said anything about the Newton ball because mine stopped working. I pulled it apart and it seems the problem that stops it from moving correct is the sleeve in the Playfield
It is not very smooth where the ball sits and I think light deburring will make a difference
I’ll keep you posted

#1479 1 year ago

It is back together and working much smoother than before, I forgot to take a pic after cleaning it up but it definitely made a huge difference in the way it moved and feels.

#1480 1 year ago
Quoted from Hdmike444:

So I should have not said anything about the Newton ball because mine stopped working.

The mystery newton ball on my Premium started acting up tonight. It's not the mechanism itself or the switch gap, but the positioning of the switch cup. I drilled out the 2 mounting holes slightly bigger so I could position the switch assembly better without having to bend the bracket. Maybe it's also because I have the older spoon posts, but they have to be absolutely 100% centered in the cup. Test by pushing down the back of the plastic cup and if the post moves even a fraction, adjust it again. When it's not centered, the switch may actually open more in one or more directions and the switch doesn't close.

Man this may explain why I’ve been feeling like my mystery ball doesn’t ever do anything.. thanks for the explanation!

Can you take a picture of the wedge installed? I think I get the description but not sure. I've been having the auto plunge issue lately too.
Thanks

#1483 1 year ago

Dumb question: Which is the Newton ball vs the captive ball? Newton is the MUMMY and captive is the orb right?

On a premium, they are both newly design newton ball mechs.

Oh, I found the picture, didn't scroll back enough.

(Actually, I think it didn't load the first time.)

Quoted from treborlicec:

Ah, so all these posts about rebuilds are for the same mech. No wonder I was confused as to which is which.

#1487 1 year ago

My pro used to plunge perfectly when going for the upper super skill shot. It now mostly hits the post below the little flipper. Auto-plunger works perfect. Could my spring just be a bit worn out?

#1488 1 year ago

My advice--if the auto plunge is perfect--don't screw with it! Wait until you have auto plunge problems before touching anything.

#1489 1 year ago

I would recommend getting the screwing started now. You’re going to have to learn it anyway.

#1490 1 year ago
Quoted from Tranquilize:

If he is only adjusting the manual plunger, he doesn't have to adjust the shooter lane guides, or auto plunger at all. You can adjust the manual just by changing the position of the plunger where it hits the ball. You can increase or decrease power that way (or by changing a $2 shooter spring too...)

#1491 1 year ago

I speak from experience. Mine came with the auto working 100% and the manual hitting the post. Got the manual to 100%, auto went right in the dumper. Took me forever to get the auto back--shoulda left things alone...

I had to adjust three times to get it right. Wasn't that long, considering how long adjustments can take on various machines. Now I'm confident that I can adjust it in about 5 mins. Gotta go through the pain, so may as well get it over with.

#1493 1 year ago

How do you adjust the manual plunger so it hits the loop? Mine hits the post but auto works about 95% of the time

#1494 1 year ago

You can also just plunge softly for the skill shot below the loop if you dont want to mess with the manual plunger.

#1495 1 year ago
Quoted from Who-Dey:

I have been doing that and also plunging for the left lane which awards a big skill shot
I never knew the plunger should reach the fireball loop until reading it here

Ok I guess we’ll see how things work. I know the ramp sticks up sometimes. The seller informed me of that
