8:20 -> me at 10:30 p.m. still doing homework and watching this
Answer: none of the above
He said hi to everyone so i just wanna say HELLO.
watching this and knowing its not going to be used at all.... :)
And then Martin invented the clock again and then this video became pointless
@sehhi vooty But this looks WAY cooler
installed in the MMX surely the overall vibration of the MMX would provide the required jog and prevent them getting stuck in the first place? Just a thought :-)
why not make the plywood one as close as you can get to original then put plastic plating or any other nonstick material on the inside of the gate
What site was he using at 7:43 ?
So if some of the gates tilting backward is causing a problem it sounds like them not being vertical is a problem unless it is 100% required.
maybe)?
Esta muy jodido ....ouuuhhh yeaaaahhhh
This is difficult to watch. Too much nonsense.
we love it
Your test is very different compared to your actual 3D implementation. Friction for sticking depends on the force (grams in your units) and surface area. Your "2D" test designs have smaller contact area than your 3D designs which have contoured profiles which grip with the same force but increased contact area, hence more likely to get stuck. Good luck.
I'm still mad at you that it took me almost one month to accidentally find the second channel
"I have a small scale here[...]" for small scale experiments? bdum-tsss
It is not Marbe Machine X anymore, It is Meme Machine X now! ;D
All we have is time, you’re having fun and learning lot’s, your dream is awesome enjoy the journey. You feed Wilson through the nose...😳
So if some of the gates tilting backward is causing a problem it sounds like them not being vertical is a problem unless it is 100% required.
put them there to Level the machine to a level "standard" before each performance. One Design! One Angle!
New pressure design for marble machine, new haircut for Martin 😁
Nice. He could have had this z-solution in November 2020. The priciple was posted 8th November last year by Jens#6124 on the Wintergatan Discord channel into the mmx community section.
Have you tried (or do you have space for) a spiral track?
Use some grqphite
9:14
You have been testing the gates out of MMX context, ie on the bench. Stuck marbles seem to free themselves with the smallest jog, in one instance a very light tap. When installed in the MMX surely the overall vibration of the MMX would provide the required jog and prevent them getting stuck in the first place? Just a thought :-)
Someday, when I am old and gray, I will say: "I was there when Martin started the Marble Machine X". It still won't be finished but that's not really the goal anymore; it's now about ingenuity and experientation.
I think the 'slow descent into madness' subplot is what I really enjoy the most about your show.
This NOworld journey for me is so enjoyable - part of me asks, "Does this have to be finished?". Looking forward to completion, but will surely miss the journey that got us there.
Sir, I salute your engineering skills, bravo!
The problem is gonna be that eventually the hard steel bearings will cause indents into the much softer wood, which leads to the decrease in output force of the marbles , but also causes them to jam much more often.
I'm still mad at you that it took me almost one month to accidentally find the second channel
Martin: Weekly videos is too much! I need to do fewer videos Martin 2 months later: DAILY VIDEOS IS PRETTY DOPE
Why not attach cam behind the track that will shake the marbles loose if they get stuck?
Have you also considered trying different materials? I think aluminum or some sort of plastic have different friction coefficients to plywood and might also have a significantly influence to the marble flow... Especially for the last question mark design with nylon or similar you might have other results...
And what about dust or other garbage in marble pressure gates?
One Design! One Angle! Chant it from the roof top people! ! You keep saying you want One gate and track that is the same across the the whole machine. That way you don't have to make a custom one for each track. One gate would be great. One design leave you with only needing a few spares around on hand for a tour. But ... some of the gates leans back at an angle. There is your Mole you designed in. Keep all gate the same angle, just direct the marbles using the wire tracks to hit the mark.. One Design! One Angle! Chant it from the roof top people! ! Ps. You put levelers on the machine. Do you plan to set the Machine at a 30 degree backwards angle one day and 22.5 forward the next day, No you put them there to Level the machine to a level "standard" before each performance. One Design! One Angle!
чëткий вариант! круто. жду новых видосов.
what you wshould be mesuring is the amount of pressure per ball added
Use some grqphite
What if you introduce some kind of vibration or oscillation on purpose, to overcome the issue with the marbles getting stuck? just to prevent them sticking nad maintain minimal amount of kinetic energy at all times
9:16 --> nerve break down
PMA hodler? Are you into cryptocurrency, Martin? (I am...)
You sound swedish. Or norsk (I either don't know or don't remember what "norsk" is in english, but if I'm even close to right, you know what I mean). edit: The name of your channel further proves my theory.
Did you just say. "Beta Test"
"Marbles are evil, lets do 30" lolol
Sir, I salute your engineering skills, bravo!
great work. Resist the urge to over-optimize. Go with #4--less than 100g of weight to resist, and doesn't get stuck.
I have an idea ! Tu veux utiliser des lames ressort (+ feutre ?) pour ralentir les billes, réglable par vis. D'une manière générale, une buté mobile. Plus une bille arrive vite sur la lame, plus sont énergie sera absorbé, donc ça devrait, aussi, réguler la vitesse.
@wintergatan you have dragged on this for too long. Tried many solutions and they all have the same issue: marbles getting stuck under pressure. Have you considered adding vibration to the marble gate system? The marbles usually get going by a slight nudge from another marble. You can probably try putting some sort of mechanical vibrator that can be powered with the machine drive train or even some sort of hammer that strikes each channel when the marble gate closes. I worked at a pharmaceutical plant where they had a similar issue feeding small tablets into a container using a queue not unlike the marble channels in the MMX. The solution was to add a small and simple pneumatic hammer that was in sync with the machine feeding cycle. Each time the machine fed tablets to the container, the hammer stroke several times in quick succession to make sure that tablets did not get stuck. That solution would not work in the MMX due to noise concerns but the idea is the same, use vibration. This would also work for the pickup section of the fish stair. Hope this helps.

Random question, could you have a "shaker"? something that repetitively hits or moves the channels? Either a bar that taps the back of the channel or shifts it to cause some vibration.
O long time no see
MARIO!!
ever thought of a graphite lubricator mecnanism that continually applies graphite as a dry lube to the marbles???
If there is some sort of solidworks for these designs, that would be great for testing before CNBC.
Don’t worry about it taking so long. I believe many of us are makers at heart and love to learn with you. Of course I want to see the final machine one day but that would mean the journey would kind of be over. Sad day 🤣 While we‘re at it, I am so so so impressed how your skills and personality have evolved over the course of that project. Oh, and can you make some music on the machine for us?
I have just had this idea... Maybe it can help. When being played, the MMX constantly vibrates and moves around. Whenever a marble gets stuck in these gates it really doesn't need much to make it fall through. So maybe, and that is a big maybe, you don't really have to care about them being stuck just a little and while they are built into the machine everything runs smoothly. So I think you should do a test with the gates built into the machine. If you are lucky none in a couple thousand will get stuck...
You didn't tilt the two question-mark-paths. If you tilt them in the way you mount them on the machine, the marbles will actually have to go *upwards* which will get them always stuck, if the marble lane feeding it is running dry!
don't dent or mar as easily. Wood will need some finishing done to deal with the same conditions.
9:14 Gunde Svan plays Mario?
I believe tin the ?! The vertical path on the right should not be completely vertical. The marbles gets stuck when the center of the bottom rightmost marble, is pushed further right, than the center of the top rightmost marble. If the path forces the bottom rightmost marble's center to always be further left, than the top one, then it should never get stuck (as long as the width of the track doesn't allow for a similar problem. But try to add a small wedge for the bottom marble, forcing it a little bit further left.
just and idea. why do you need the zig zag vertical. culd it not just aswell be horizontal. that way the slope would be the same but the pressure bleedof wuld still work. and you could make all the gates in one piece of playwood. seams like it would work
14:05 "Wilson, food time!" was the most adorable thing I've seen this week!
marbles are evil
Hi Martin, can we that don’t have engineering experience help in any kind of way? (except being member of the channel of course)
You need lateral force, and force ball rotation, also consider changing wood type for more friction. The you need a Peogressive zig zag design thats get closed in a logarithmic way.
Have you tried making the wooden surface smoother? Reducing friction should work.
Why dont u use another material with less friction than wood, cause this is the main reason they get stuck
Marbles = Evil --- > Evil Machine X ?
I found you because of the second channel. Thankful for it!
I have a question, why didnt you tried to angle the other designs beside the first one
Discordians are the followers of the Principia Discordia, not users of Discord!
cool, but why is this on my recomended?
I was wondering where the daily updates went! I wasn't subscribed here. Life is good!
PMMA Hodler? Are you trying to tell us something? ;-)
still waiting for that monster stand up and eat you....
po, de boa, ja virou um negocio muito lucrativo rpa ele isso. toda a hora ele "cria" alguma coisa e atrasa mais ainda ....está me cheirando marmelada
14:05 "Wilson, food time!" was the most adorable thing I've seen this week!
"Marbles are evil." -"Marble-Machine" Martin, 2021
You know Martin, if you're willing to use math, you can calculate the exact amount of pressure in a very satisfying and not overly-complicated way. Then you can call yourself an engineer with no reservation.
New haircut :)
Martin, the vertical exit, though pleasing to look at, might provide too much of a pressure drop at the very end. The pressure has to go somewhere and I think it’s amplifying the friction against the 90 degree wall, even worse when the gate is angled. There might be a sweet spot, less than vertical, where the pressure is being reduced, but not enough to cause the friction to overcome gravity. If, of course, we still believe in physics. 🙂 Love this content!
why dont you place magnets around the edge of your test table so they dont keep rolling on the floor?
You seem very happy ^-^
You also have to take into consideration the amount of vibration going through the gates during use, and how much vibration it takes to unstick the ball bearings. I'm fairly certain the machien will be vibrating enough to prevent them from sticking during operation. Part of the sticking is probably also related to the the compressibility and friction of the wood, where the ball bearings are pressing and sticking into the end grain of the wood. If you can get a block of HDPE, try making a sample gate out of it, instead of plywood. You could also try coating the bearing path with some kind of lubricant like a spray-on lithium grease or silicon grease/oil
on part 5, change the angle where it get stuck. Friction on the wood is to big
Have you ever tried with a material with less friction?
couldnt you do the marble channel in a different material?
9:13 are you okay?
How about a double spiral channels?
Where did his hair go
seems like the reason the question mark is getting stuck is the static friction between the wood and marble, since the pressure from above is high enough to make the marble stick. If friction is the issue, some graphite lubrication might solve the problem nicely. another potential solution would be to make this part out of clear acrylic (like the conveyor belt) which at a glance seems like it would have a lower coefficient of static friction with the marbles than wood, and offers some aesthetic appeal
HAHAHA xD I love your humor! The Mario reference was AMAZING!
I love your song star machine 2000
I can't wait for the new machine to be finished!
9:14 looks like... he lost his... marbles
happen in normal operation. You need to measure successive falls of the marbles ... and you might need a sideways escape in your testing to enable this.
I love the new format 😍
im finally able to watch this video now that ive binged everything from winergatan 2
4:16 I see you are a fellow investor...
If you increase the first bend of the question mark one with the radius of the marble it might eliminate the marbles getting stuck! Because it seems the two marbles fit fairly perfectly in that turn! I think that the marble that gets stuck finds enough surface area to get stuck on in the second turn with the additional pressure of the second marble which find enough surface area against the back wall with the pressure from the weight of the remaining marbles, causing that first marble to get stuck in the first place. I think that if there was more area between those two turns then they wouldn't get stuck as easily.
I was wondering where the daily video was from the second channel :P
Perhaps the lack of pressure is what causes it to get stuck
Angled table seems too realistic, what about a table with a bunch of marble size holes that empty to a funnel that pumps marbles into a container nearby?
me: "you can't convince me. the best youtube moment is--*" martin: ****9:14****
The haircut looks great! :D
5:45 Now you make it like this: |_ |_ |_ |_ what about this: / \ / \ the right angles are for me not that simple. But with the second version you will even by mounting it 20° rotated not have a hill in that the marbels have to climb if the bottom side as in your design is near horizontal it can easy be tilted back so the marbles (with nearly no pressure) have to climb.
