  • 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!

  • 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.

  • 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!

  • 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

  • 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

  • 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.

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.

  • Go with the tracks that have the highest pressure below 100. You don't want to go with the lowest pressure, those are the ones most likely to get stuck. You said anything below 100 was acceptable, so why not take anything below that threshold? Imagine that you had a rocket engine that you wanted to keep below 500 celsius. You have one orcket engine that maxes out at 400C. Another one barely goes above 50C. If you disregard all other factors, the 50C engine would be best. But then you'll realize that the 50C engine isn't firing correctly and you didn't account for that because you were only looking at temperature. Same goes for the tracks. You need it to make sure that the marbles will come out more than anything else. Keep the pressure within acceptable limits, but not too low, or you're losing your guarantee that a marble will always come out.

    trevdaktrevdakVor Tag
  • The more pressure gets relieved, the more pressure there will be between the marble and one side of the path, the more likely a marble is to get stuck against the side. I see a trade-off :)

  • I saw once, a manufacturer that produced steel ball bearings like yours. The process is incredibly simple and reminded me of rock companies that filter aggregate using different sized screens. The hot steel balls roll down a ramp of two steel rails. The gap between the two rails changes and "filters" out different sized ball bearings. They don't all make it into the same baskets. Some that are border line do make it. The companies are more accepting of certain tolerances so they can remain profitable. Your machine is most likely more strict about the sizes that fit and those that don't. I probably didn't see you talk about this already, however I wanted to ask, have you checked the size of each of your marbles? The infrequent occurrence makes me think there is a random marble that is a different size. It keeps coming back around at random times and that accounts for the sticking marble. Keep going!

  • Watching this video made think that the marble gates are a critical part of the MMX, and you mention that some gates are inclined. These prototypes show that some designs are good when vertical, but when inclined they fail. Considering the assumption of the marble gate being critical is correct - it seems so and you have been testing for the optimum gate design, not the optimum inclination - why not consider all the marble gates vertical and design what is around them in function of the gate instead of getting the critical part inclined in function of less critical parts? Again, considering that the gates are indeed the most critical part in regards to the neighbour parts.

  • Well you are trading pressure for friction. No surprise it is getting stuck when the pressure is reduced that much. Maybe making the wavy channel longer so that this "pressure reduction" will be more spread out among the marbles would result in less friction per individual, preventing such situations?

  • I do not understand having over rotation while marbles are inside the tubes. When marbles are touching each other, the back of marble “A” will be rotating the opposite direction of the front of marble “B” directly behind it. This would cause friction between the two marbles. Over rotation is beautiful on the top section but I cannot understand using it in any section where the marbles are in contact with each other. Maybe someone on here can help me understand. 🤷‍♂️

  • Romans 3:23 states: "For all have sinned, and come short of the glory of God;". We are all sinners, that have committed at least one sin in our lives, which earns us an eternal punishment in Hell. Revelation states 21:8 "But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.". God sent his Son, Jesus, to Earth as a perfect sinless sacrifice. To take on all the sins of the world; both past, present, and future sins. Shedding his blood on the cross as a blood atonement for all sins. After dying on the cross, he rose from the dead on the 3rd day and rose to Heaven. To show life after death. To show everlasting life through Jesus's sacrifice. John 14:6 states: "Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.". Romans 10:13 states "For whosoever shall call upon the name of the Lord shall be saved.". Eternal life in heaven is just one prayer away. All you have to do is believe that Jesus Christ, the Son of God, died on the cross for your sins. As an atonement for your sins. And rose from the grave on the 3rd day. Ask Jesus to save you of your sins and give you eternal life in Heaven. Salvation is a free and everlasting gift from God. Please don't let pride drag you into eternal punishment in Hell, but ask Jesus to give you eternal life in Heaven. If you're getting a strong feeling of resistance while reading this, it's because Satan doesn't want you to get saved. He wants you to resist, and think it's not real. He wants you in Hell for all eternity with him. Hell is not a fun place, like worldly people like to imagine. It's everlasting torture with no relief. I'm only taking the time to text this, because I want to get the message out. There are so many distractions in life keeping people from witnessing to other people. Keeping people from thinking about salvation. Keeping everyone from thinking about life after death. Please, ask Jesus into your hearts to save you of your sins and cleanse you from all unrighteous. Ask him for a place in Heaven, and he will save you from eternal damnation in Hell.

  • Over-rotation in the gates is completely pointless. It doesn't reduce the pressure on the moving parts, all it does is slow the movement of the marbles down, which is not a good thing when you're playing very fast.

  • Regarding your concerns about marbles getting stuck due to a non-90° angle, couldn't you 'just' carve the channels at an angle, so that they remain in the proper angle compared to the ground rather than the wood in their blocks? Alternatively cut their outside profile to match the required angles instead of 90°? Think of it like a compass, where the needle (your carved track) stays in place despite turning the outside (the exterior of the block). While this means you'd have to match the right block with the right track on assembly, they should maintain their performance. (If it's made with some tolerances for the machine standing at an uneven floor.)

  • I think I see what is happening. Where it jams is where two adjacent marbles are pressed against the same side of the channel. In the original prototype, at the second bend, the marble on the corner was pressed against the upper/outer wall, and the marble before it was pressed against the inner/lower wall. That meant that both wanted to rotate in the opposite direction to start falling, and were therefore helping each other. (A clockwise cog drives an anticlockwise cog.) Here, the two marbles that jam want to rotate the same way as each other, and so they resist each other's movement.
