Martin, I am studying in aircraft design and one of the thing we learned was that designing something has an iterative process to it. The reason behind that is that you can always refine the design, make it 10%, 5%, 1% better by marginal gains. Although i thought the design of planes was perfect all the way through, my studies showed me that the planes flying nowadays are far from being designed to the perfection. The chief engineers sometimes have to tell their engineers "okay your design might be able to be 2% more efficient if you work for 10 more months but we need to deliver the design next week". I feel like I am seeing a version of that in the MMX project of you trying to make every component of it 100% perfect. It is definitely not a bad thing as you are converging towards the optimal solution but maybe it is sane sometimes to not scrap parts which are 98% perfect to make a 100% version of it. In aviation the rules are written in blood and all the experience gathered by engineers before is put towards the next generation aircraft. For the MMX you are trying to anticipate all the risks and issues but maybe you should try seeing them happen? Finally, i wanted to say that you are assessing the reliability of the MMX only in the funtion "play the marbles" but maybe you should also think about assessing its reliability in the other type of functions such as "being able to compose", "changing the song" and so on. It would be a shame that during the world tour you can reliably play 1000000 marbles but have something that brakes or malfunctions once every 10 song changing. Anyway maybe that could help you! Your work is really inspirational and good luck to you and Wilson ! :)

[@Straylight4299]

I'm pretty sure he already has that on his list, hence the steel programming plates with welded on bolts for example. He probably will move on to such tests once all instruments are implemented.

[@BrunodeSouzaLino]

Perfect is the enemy of good. On the MMX, you can see that fixing one issue not only doesn't solve the problem initially, but introduces new problems that didn't exist before. Martin is too focused on getting all aspects perfect forgetting that his design doesn't allow for that. That machine doesn't have any fault tolerance built into it, despite he convincing himself that it is reliable or that will reach a level of reliability that is impossible. He convinced himself he can do that and will most likely spend the rest of his life never achieving that goal.

[@ussarng4649]

Maybe not, ... there are features on the marble machine that allow for composing and changing songs. Also this is the first marble machine of this type, so yeah Martin is really fussing over it, but not over much (in my opinion). At first in reality he was learn how to make a marble machine. Now he knows a lot about how to build a marble machine and is now refining the MMX not so much his building skills. It isn't like there have been such musical instruments for hundreds of years and he is ignoring those and in a manner of speaking trying to "reinventing the wheel". I think it won't be over long until this Marble Machine is done. It being done doesn't preclude the possiblity of later versions being adjusted and tweaked.

Martin: I'm not against prototyping a redesign for the divide by 4, but I DO request that you wait until you have most of the channels operational before you actually consider doing it. Because the more channels you have running, the less activity the divide by 4 sees, and I suspect that a fully operational MMX will use that function very little. So the problems it's causing now might be an overrepresentation of how "fragile" it is

[@claytonfs]

This! He should stop focusing on problems that may not be problems when the machine is being used as intended.

[@YeaSeb.]

in fact, the marble test should end with a different rating for every part depending on how overestimated their testing will be. Like how the marble drops and funnels for the 4 channels he has working and the divide by 4 are doing more work than the mable divider in these test compared to an actual song with all channels enabled.

[@dovayaj9023]

With the current tube configuration at the top, it seems as though the early vibraphone channels receive marbles only from the divide-by-4. While this shouldn't create a marble supply issue if the other instruments don't play too much, I just wanted to put it out there that the divide-by-4 will need to function quite a bit to supply the vibraphone.

[@robertcarlson8867]

I'm with Martin on this one. You can't design just for the average case; you need to cover all the edge cases you can too. If there's a song that has, say, a long bass solo, these issues could definitely pop up again with the divide-by-4.

[@TheJohnreeves]

I had a big paragraph explaining why you're wrong, but I argued myself to the point that I agree. I guess the function of the divide by four is to have marbles circulating as soon as the song starts. If the main divider holds enough, that shouldn't be necessary.

[@willhart2188]

Divide by 4 did work really well on previous tests even when you played the machine for hours. It'd be sad to see it go.

[@YourSweatyUncle]

With like 3 channels yes. It needs to feed like 40

[@1kleineMax1]

[@brendansimons6811]

Another quick trick for using setscrews without causing damage on a soft part: Make your hole a little larger than the PMMA pipes, and insert a metal "shim" between the plastic and the set screw. The shim can be made from rolled strip metal, or by slicing and slotting a metal tube. If the shim is thick enough, it will clamp down evenly in all directions when pushed by the set screw.

[@MostHolyPlace2]

A Draft Angle would help, similar to a Taper-Lock Bushing.

I know nothing about actual engineering but one of my favorite things has always been brain storming or trouble shooting problems people have (outdoor field research often involves adapting or modifying something someone invented for one purpose to use it for what you need). So it does my heart good when someone who knows more than me suggests a solution that popped right into my mind! I couldn't do any of the technical stuff but those little moles are right up my alley (or lane, if you will)

[@2lian]

NGL, I love the divide by 4, but your arguments makes sens. I would let it on though. Test it more thoroughly as you continue working on the machine, because, as for now, it worked great. I think that you have much bigger ploblem on the machine to overcome. Focusing on this little easy (maybe) problem may be satisfying now, but could be a mistake in the long run because the divide by 4 is cool. Stick a note on it saying "Big Martin is watching you" and when time comes, decide of its fate. Mabe he will be scared and work like a charm.

Be aware that surfaces will wear over time, changing the characteristics of things like gears and balances and counterweights (especially with wood and plastic parts). This is why machines are designed to be a bit "stiff" out of the factory and need to be "broken in" before everything will move smoothly.

[@duckweedy]

Presumably that is why all pieces can be taken out easily and replaced. Main thing is that when repairs happen it doesn't need too much work to get it back into performance mode.

[@fawode]

I'm also concerned about the fact that if the machine moves a lot during world tour, it will make it change a bit in a lot of places, maybe Martin should build and dismantle it several time before touring

The perpetual movement of the marble are parts of what a marble machine is. The mmx wouldn't be a real one if it just used marble like that, there would be no point in doing it like that, just build a pneumatic/lever one instead. The elevation mechanism are the soul of the machine.

[@RahLoh]

with the 1 to 4 divider relying on swinging freely until full, any other vibrations through the machine could effect it! if its going to with with 3 marbles waiting for the 4th to trigger it? maybe this could be fixed by having the 5th marble in the cue activate the divider? instead of a counterweight you want a trigger!

[@KnowArt]

Yes, redesign of this divider seems needed. This look vulnerable, as whenever one marble gets stuck at the stairs it will eventually lead to the divide-by-four to stop working on all channels at once, instead of just that one blocked channel. Or did I miss something? Maybe the divider works different than I can see

[@ODDnanref]

It's a bit more resilient than that I think. If the length of tube is long to fit an exact number (no marble half in) or leave the last marble out of the tube by a large number then it just gets pushed to the next one or simply ignored. Sure you have one les channels but it should still work.

[@ameunier41]

@@ODDnanref can the other channel be filled when one is full?

[@ODDnanref]

@@ameunier41 Like I said, it depends on how the marbles end up. I rewatched the video and in this case a marble got stuck while attempting to enter the channel. The pusher (whatever it is called, that makes the marbles enter the channels) got stuck on returning to rest until another marble pushed the stuck marble further back. A full channel, might not prevent marbles from being delivered to other channels. It is the whole reason why he has modules on the top of the machine and why he wants marbles flush. If the a similar effect can be achieved on the 4 way splitter channels then it might not matter. Either way, this discussion is purely hypothetical as he is reworking on that entire part of the machine.

[@ameunier41]

I think it's the impact from the incoming marble that cause the chaos. Raising the angle would make it worse.

There are a lot of moving parts in that area. Steeper angle will give more force, but it will also increase the pressure on the stairs.

@@Temperans Exactly, that's the point. It looks like the marbles don't actually fall in fast enough, getting caught on the edges of the stairs

@@L3K1P The thing to consider with that is raising the divide by 4 raises the front sloping pipe which raises the marble divider. Needing to raise it too much could cause a redesign of a large part of the machine.

The current system is quite close to working, is beautiful and may take less time to get working than starting anew. Using a stiff rubber, silicone or felt instead of sheet metal strips to guide the marbles into the stair would do a lot for reducing noise. Adding curvature to that strip, conforming to the shape of the marble instead of a flat strip may also help in preventing the marbles from moving to the side as they enter they fish stair. Also instead of the tape on the bottom fish stair attaching a larger guide to the pipes covering both the side of the pipes and the bottom fish stair might work better. I'm curious, how many marbles are in the system in total? Is there a way to calculate the likely hood that the staircase occasionally going up with only 2 or 3 marbles would cause a channel to be empty and unable to play a note? Would adding more marbles to the system make it more resilient? I've been following this epic since the very beginning and am starting to feel the melancholy one feels towards the end of a great book. The machine really feels like it is getting close.

I think he is also using the machine a lot during the last year, which make me thing that by the end of the project this problem will have comes up and will be assesed

[@DeFaulty101]

Don't scrap the divide by 4, it seems so close to perfect function! Also, if you have the funds, I would advise getting a second CNC machine to forever cut your CNC time in half.

[@jacobpalomarez5349]

I feel like the removal of the divide by four is a bit premature. It seems like it was working fine. The focus should really be on critical marble fails and not noncritical ones.

[@joshuasims5421]

Balancing the four lane marble pickup was truly inspiring.

[@fredofredofredo]

Martin please don't go crazy trying to get it perfect. The hard truth is it'll never be perfect, since you'll need to disassemble and reassemble it many times and many external variables could affect it. I'd suggest you try and get the other channels done and whack any apparent moles that affect it greatly. From then on try and "debug" it and squash any other problems that pop up. But I feel like it's totally fine for it to drop some marbles here and there. I do believe in this project and I do believe in you being able to deliver it, but I'd rather see it playing in a year rather than not drop any marbles in who knows how many years.

[@chungonion]

Agree, I think Martin is a bit obsess on not letting any marbles falling from the machine and also obsess on making the divided by 4 stairs picking up all 4 marbles at all times It do pile up a bit however the stacked up marbles are very unlikely to overflow at the rear of the pipe, as someone mentioned, with 30 channels or so, those will also pickup by other channels before reaching the pipe that lead to the divided by 4 steps. Also, the marbles will not fall out of the machine simply because of not having marbles on the steps~

Your engineering is continuing to improve. Taking a problem one at a time is the only way to really know what is going on. Well done Martian !

[@richardgregory4640]

No-oooo! Leave it as it is. You could spend forever going back and redesigning everything to make it marginally better. If it works then leave it be. Sometimes good enough has to be good enough.

[@kaltenbach.alexander]

The slow-mo is stunning. Even MORE!

[@kaltenbach.alexander]

I love how alien the machine looks in the close up angles. At times the clear pipes are very hard to see, and it looks as if the marbles are floating, beautiful! 11:30

I may be alone on this one but if you want a perfect, tight note playing machine you could just open a DAW on your computer and program in the exact notes. This machine you are building is not perfect, but it has character. It being a bit whacky and having some "silly" marble paths is the reason so many people decided to follow this journey. Those individual parts are the reason why this musical instrument is so interesting in the first place.

[@Tyguy370x]

I love watching your videos Martin, your attention to detail is so inspiring

[@detheagle3746]

Can't wait for the next big test! Hopefully we'll get to see it this week. I'm not really sure why the "divide-by-4" is nessaccary? Why couldn't it just be a basin like where the conveyor picks up the marbles? Sure, the farthest tube would fill up quicker than the rest and it wouldn't be even, but that would remove the need for balancing and it would remove the noise. And, the rest of the set up wouldn't need to be changed, so it would be a relatively quick fix I think.

[@zorod5475]

The conveyor use to also have a divider. The basin is a recent change.

[@InventorZahran]

What about adding a felt pad to dampen the DivideX4's noise?

[@detheagle3746]

@@zorod5475 And that's why I'm saying remove the "divide-by-4" and put in a basin? ​ @InventorZahran Could work but I'm not sure there's room, so it's have to be totally redesigned (probably) and if so, it'd just be quicker to slap a basin in instead

Giving up is not an option, we all are supporting you and not a single person agrees that you should give up (that I've seen). Please, just keep going, I'm a patron supporter, and I support you and your work because it's a thing that should be in this world. It's unique, and nobody has the time and the mindset to make something this complicated in today's society, but you. You have the brains, the financial support, the emotional support of thousands of people, and a world tour to look forward to. Don't give this up. ♥

RUST - I don’t seem to remember you addressing rust prevention and I’m so worried the MMX will be in and out of the tour van and will be rusting very quickly! Please calm my nerves and let us know what and how this can be addressed. I noticed parts of the marble divider has some surface rust.... 😧

At 8:13 5 marbles went through! I don’t think it happened again though so it probably won’t be an issue!

More mables getting through is an advantage over not enough marbles getting through.

@@zorod5475 that’s true, but if you want 4 to go through every time it’s not so good.
