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.

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.

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 :-)

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.

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...

Junkboy888 Vor 4 Tage

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!

Luis R Vor 5 Tage

@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.

Orlando B00m Vor 5 Tage

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...

Martin W Vor 5 Tage

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!

Martin Fyhn Vor 5 Tage

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.

KanonOC Vor 5 Tage

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

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.

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.

Larison Johnson Vor 6 Tage

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!

James Daniels Vor 6 Tage

why dont you place magnets around the edge of your test table so they dont keep rolling on the floor?

Lennart Krüger Vor 6 Tage

You seem very happy ^-^

Ian Adams Vor 6 Tage

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

Geoff N Vor 6 Tage

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

Lòriethalion Isilgor Mithredel Vor 6 Tage

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.

trevdak Vor 6 Tage

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.

Janne Peltonen Vor 6 Tage

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 :)

J. C. Vor 6 Tage

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!
