Quoted from Mathazar:cottonm4 - maybe this one is for you?
I'm at a loss and so beyond frustrated that this is starting to get comical for me. Just when I think I've got my drop target issues squared away on my Meteor restoration, another one pops up. I won't go into the details of all the drop target problems I've had to date and how I got around them - instead I'll just describe the current, and hopefully last, issue in front of me: The "M" target in the METEOR bank falls after an all-target-bank reset (all four drop target banks reset at once), the kind of reset that is done at the start of a new ball or new game.
The 111/222/333 banks work perfectly. No falling targets, no bricking. These banks are a slightly different design (non-memory, no coils, no bracket fingers for resting targets) than the METEOR bank.
With the METEOR bank on my bench, resetting the drop targets manually (as quickly as I can to mimic the coil reset) does not result in a fallen target 50 out of 50 times.
With the METEOR bank in the game, I can down all the targets 1 by 1 causing a reset to occur repeatedly over and over as depicted in the video - NO fallen targets.
However, after a ball drain (or start of game) where all four of the drop target banks get issued a reset at once, the "M" in the METEOR bank falls most of the time (and in the case of the video I recorded, the "R" also fell!). Since I'm running on the 2021 Meteor code, what you're seeing in the video at the start of a new ball are all the drop banks getting reset including the METEOR bank for the Skill Shot, the "M" target falling on its own to inadvertently complete the Skill Shot before the ball is launched, and the drop bank getting reset on its own with the "M" usually staying up after that and all subsquent downings until the start of the next ball.
Here's a video of what I'm talking about:
The sequence ("M" falls only when all of the target banks are reset at once but not when just the METEOR bank is reset) suggests that some sort of vibration is occurring when all the banks are reset at once causing the suspect "M" target to fall on its own. When the METEOR bank is reset on its own, the "M" rarely falls on its own. And on other rare occasions, the "R" target also falls down.
The METEOR bank has coils for memory so the hardware configuration is a bit different than the other three target banks (111/222/333) that never fail. One big difference is that in the METEOR bank, the drop targets rest on the coil bracket "finger" and not the playfield or target bank ledge.
Here's what I've done to try to find the culprit:
- I tried three different targets in the "M" spot (original tombstone, new Swinks tombstone, and new PBL flattop). All do the same.
- I tried two new springs and the original, older less-tensioned spring on the target.
- I swapped the memory coil bracket (which has the "finger" that the target rests on), bracket spring, target spring, and target itself from a "working" position (the first "E") with the "M". The falling target issue stayed with the "M" position and did not move with the target/spring/coil/bracket to the "E" position suggesting there is nothing wrong with the target, springs, coil or coil bracket.
- I tried putting a "riser" piece of metal on the reset bar that forces the drop targets to go higher on reset. With the drop target being forced to a higher position upon a bank reset, theoretically it gives more opportunity for the coil bracket finger to "spring" into position and catch the target on the way down from the reset.
- I moved the entire bank hardware back about an eighth of an inch on the playfield, filling in the old holes and drilling new ones, to provide more clearance between the target face and the edge of the playfield cutout. It wasn't until after I moved it that I realized the clearance/closeness of the target face to that playfield edge probably doesn't matter for this specific memory target bank because what's closest to the target face is the top, silver rod that is part of the bank assembly. In other words, the target can never come into contact with the front of that playfield cutout edge, but the target faces DO touch that silver rod. Pretty sure that's by design - targets that do not fall on their own also touch that silver rod. It's the same on my Eight Ball Deluxe - that 7 drop target bank (with memory and the same kind of target coil/bracket) also has that silver rod and the target faces are touching it in the up position

I'm starting to run out of ideas - I've been working on this one problem for about a week, a couple of hours or so per night. Would appreciate any other ideas that folks may have![quoted image][quoted image]
