Quoted from modfather:

So....what is the fix on the crackling sound ? My pro does that along with my AS pro. My GB prem does that at high volumes as well , what gives man ? Does Stern build there games that they cant handle their own power at high volumes and causes the amp to get overloaded and start clipping on and off ?

Quoted from PinMonk:

Slo-mo hi-res is awesome for pinball diagnosis in situations like this. Allows you to see the actual root of problems you may not have even considered.
Also, you might want to Ohm out the coil for the auto launch and see if the resistance is substantially different from what it should be.

Spike and Spike 2 have tech alerts just like SAM and Whitestar, but they wouldn't cover something like this auto-launch issue, then or now. Some issues you just have to soldier through until you hit a solution.

I hate the new Spike/2 switch diagnostics screen. Super crap. They have a color screen now, why don't they have a system like JJP with a color PF image and an indicator of where that switch is when you trigger it? I mean Pinball 2000 18 years ago had better diagnostics!
Stern has all these new programmers - put one of them to work completely overhauling the system menu for the color screens they have NOW, not the DMD-look they kept from Whitestar/SAM.

Stop all sales. Recall.

Quoted from Who-Dey:

I updated today but didnt notice anything like that. I only played 3-4 games though.

Quoted from cscmtp:

So I am still running 1.01 is it definitely worth upgrading to 1.3? Only reason I ask is I've used pinball browser to change all my songs and it takes some time to redo that. Just curious what others think.
Any chance it could help with a weak left flipper? My left flipper SUCKS compared to the right one...has since the day I opened the box...

Quoted from db666:

Thank you, I will give this a try .. much appreciated.

Quoted from hocuslocus:

finally had a chance to mess with the prongs a little, didn't quiet get it working yet... but I noticed a huge difference by moving them ever so slightly (more then anything else I've done).
Gonna try again tomorrow, hoping this issue will be resolved finally.
I did try installing the new lower resistance coil, as you would of guessed it didn't make much of a difference. the only good thing is now I can underpower it by 15-20 and still get the same results as the default 255 with the factory coil. If it smacks into the flipper, I don't think it matters at what speed.

Quoted from Brootull:

How do you adjust the mini flipper up?

Quoted from steigerpijp:

Allright.. so three weeks of pure playing bliss have ended abruptly..
Trouble free, untill a few days ago. I dont mind the dialing in, captive balls etc. But the mummy lock has me stumped..
I dont quite understand the software logic enough as to why one switch can upset the gameplay so badly to terminate play .
I had a non registiring lower sarcophogus switch, so took out the assy to fit new 2 roller style switches, as reccomended on the forum.( the good cherry versions)
Adjusting them proves difficult, as they are a little stiff, holding the ball rolling back into the through. Too low.. and the front one wont register in the most horizontal position.. its super minimal
Question is .. Are there different length leafs with a roller?

Quoted from Gogdog:

What do you all think of this? I can rest a ball on the screw, so it definitely hits the ball every time I make the right ramp, possibly nicking, but also probably slowing the ball as well. Should I try and just bend the wire guide? I would have to bend it a bit to try and clear that screw....
Do any of your maidens have the screw protruding into the path of the ball?

Quoted from PinMonk:

So if you manually work the plunger on the launch coil (with the power off - thanks, Spike2!), does it move freely?
If it does move freely, what does the power at the coil measure (power on) with a ranging multimeter when it launches a ball?

Quoted from Shapeshifter:

Presume you checked the coil stop? Maybe broken or missing?

Quoted from Who-Dey:

Have you also pushed the auto plunger all the way forward RA77 and made sure that the prongs are touching the ball in that position also?

Quoted from pinballinreno:

Looks like the plunger is dragging in the video.
There is a very slight hesitation half way thru the stroke, could be a bad coil sleeve.
Maybe its firing crooked. Get a replacement mech or examine yours for looseness or binding when actuated.
If it fires at a very slight angle internally, it will rob all the power from it.
If all else fails, un-wind a couple rows of wire from the coil to make it more powerful. "Speed Mod" etc.

Quoted from Fytr:

Alright gents, my IMDN LE auto-launch out of the box was working correctly about 2/3 - 3/4 of the time.
I checked the ball guide and it was nice and straight and set to the furthest out/highest setting without bending anything. When the ball shoots successfully it seems perfectly aligned. However, some of the time it will either hit the black rubber post below the left loop entrance, or the tip of the small flipper across from it (so too low or too high).
So I tried messing with the autolaunch coil power settings a bit, no appreciable difference in the success/failure rate, but it does give a bit of a choice of whether when it fails you want the ball to have enough force to possibly give you a super-jackpot sometime, or just roll part-way up the ramp and then dribble down the middle.
I also took a look at the auto-launcher itself and I believe that it is the source of the problem. It is simply not built to the kind of tolerances that will keep the prongs centered reliably on the ball. It is very sloppy, and the single lightweight metal arm on the right side that is triggered by the coil firing naturally causes a sideways twisting pressure on it that can cause the prongs to be slightly higher on one side than the other, or even make both prongs move to the left away from center.
I even tried to introduce more tension in the shooter prong piece by bending the two arms below the playfield further apart so that there would some tension when it was tightened and it would be less sloppy side-to-side. This was effective in reducing the side-to-side sloppyness when using light pressure but not enough to hold when the coil fires. Even the bushings used around the rod that holds it are too large with enough of a gap to prevent it from staying perfectly straight. The net result was 0% improvement, still works 2/3 - 3/4 of the time.
So I don't think this can be solved without someone creating a replacement launcher, or maybe an upgrade kit for the existing one. Stern's launcher is as cheap as you could possibly make it, I think the metal on it might actually float it's so lightweight...
First handyman to craft a reliable autolauncher get's my $100.

Quoted from Rob_G:

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).

Quoted from V8haha:

Iron Maiden pro issue
Ball keeps getting stuck on the upper right side of the cab
Right by the upright support post for the right ramp. Ball gets airborne lands there and gets stuck little tap gets it out but not sure if anyone has any suggestions.

Quoted from Rdoyle1978:

All right, team: I’m having the Orb issue. Could someone please point me to a post with the fix? I know I’ve read it, but want familiar enough with the game at the time.
It just won’t register - if I manually move the captive ball back and forth, yes it works, but it never triggers during a game. So... ?

Quoted from Billy16:

Uh oh, I got two different opinions on the left flippers firing together. Anyone have a tie-breaking opinion based on how their game is set up? I'm not sure if mine was like this the entire time I've had it, or if it something that changed over time.

Quoted from gliebig:

Same, although my manual used to work. It now hits the post. What is the shim mod? Is that for the manual plunge? Could my spring have just gotten a bit worn?

Quoted from Tonic67:

What a great thread..thanks to all. Got my my premium dialed in tonight. Just needed a couple of tweaks..this is the best Stern pin I've played in years. Amazing job on this overall package. Thanks Keith and staff at Stern!

Quoted from Lethal_Inc:

I’m glad I passed on getting this game. The shooter and auto launch is complete BS. My MET is actually acting up a little too and it’s because the ball contact of both the auto plunge and manual plunger are not hitting center of the ball. I’m gonna have to adjust the mech AGAIN. If I want to play it I’ll just play it on location and save me the money and headache.

Quoted from CHIEF1893:

Fellow Pinsiders
I have my IM pro for about a month and while playing we notice alot of air balls. Ball lands on left wire form, when shooting center ramp flies back and lands on plastic covers. Tried putting the stern balls back that I replaced with some marco ones didn't do much, playfield is at 6.8 and centered L/R. Also when starting trooper do all 3 balls come out from left loop? Lately only 2 get trapped there and other comes out from right orbit. Thanks in advance.
