This video is amazing. I definitely agree that companies need to start planning ahead and improving their spring systems (or they could just put the perfect springs in their cubes in the first place...). Your channel has got to be one of the most informative channels in cubing, keep it up dude!

thanks!! perfect springs are hard to do I guess, since everyone likes cubes a bit different. I don't know what's the deal with the yuxin red springs since it's just accepted that that one is bad, but most cubes get it somewhat right. for example, the gts2 is universally liked but speedcubereview prefers mf3rs2 springs in the gts2. a spring compression system would make that easily accessible to anyone with a gts2.

Actually, isn't the GES system just the same with this concept? Just that the tension of the GES is the screw tension and the different GES nuts are the different spring strength. So maybe GAN came out with this idea some time ago.

Great vid and explanation! I've just started playing around with springs in 3D Printed puzzles and definitely encountered the difficulty of choosing the right ones and of the right length. I wonder if you could do something similar but adjust the spring torsionally... only a small amount but fix both ends and wind it in or out. That would give you the same travel distance but different force perhaps.

@JPerm

Thanks! I was thinking that travel distance is not a huge deal for speedcubes, but possibly matters for other puzzles if there is a lot of forced flexing involved. What kinds of puzzles are you making that involve springs?

I've only done 3x3's based off the original Rubik's cube mechanism so far but they turn well enough, the springs help overcome the roughness of the 3D Printed parts. With the right tension they're surprisingly resilient. You're right though, for speedcubes the amount of movement would already be quite small.

That's one of your best videos, it's literally amazing. You explained some concepts of physics ahd told us about springs, a really important part of cubing. And yes, I needed a year to comment this.

A very good video! Now I have finally understood the system, which I find very amazing after your AMAZING explanation w/ physics. I just couldn't stop smiling when I realised that this system was this useful, when being compared to the GAN system. Hats off!

Awesome video!!. Been looking for an explanation of the GTS3M tensioning system. Alway putting out quality videos

This is a really great explanation. I was looking up how to adjust my cube and now I understand how the adjustment system actually works and why it works that way because of the physics of the mechanism. Thanks!

Brilliant video. Your explanation was very well done and made a complicated topic MUCH easier to understand. Well done, thank you JP!

AWESOME video. I just ordered the GTS3 M a couple of days ago and it's arriving tomorrow, and I can't wait to try out MoYu's new cubing innovations. 😃

J Perm, thanks for all your helpful and interesting videos. I know that the GTS3 came out two years ago and that this video is also two years old, but I still would like to share some thoughts about the separate mechanism for adjusting the spring pre-compression. With conventional speed cubes, adjusting the screw has the effect of adjusting both slack and spring compression, which are separate attributes that are coupled by virtue of design. In speed cubes generally, the distance from the head of the screw to the center of the cube is somewhat greater than what is needed to accommodate the dimension of the cube. I.e., there is some slack, the exact amount determined by the adjustment of the screw. The springs take up the slack, thereby supplying the slackened cube with needed rigidity. The spring is held in place by the head of the screw, and at the other end it pushes against the base of the center square piece, such that the six center square pieces are pushed inward toward one another. Without the springs, the edge and corner pieces would potentially fall out, depending on the amount of slack. Corner cutting wouldn't be possible without slack. But too much slack can make the corner pieces prone to flip, especially if the spring force isn't strong enough to help prevent this from occurring. In the design used by most all speed cubes, the spring force weakens slightly when you increase the slack, because when you turn the screw out (counterclockwise) to increase the slack, this reduces the amount of pre-compression of the spring. Notwithstanding that this effect is not great, it is undesirable for the spring force to automatically weaken in conjunction with an increase in slack. MoYo's innovation provides a separate means to adjust the spring pre-compression, independently of the slack adjustment, such that it is possible to offset the effect that slack adjustment has on the spring pre-compression. Inside each of the center square pieces, there is a small cup made of clear plastic, round with a flat bottom. You rotate the cup counterclockwise using the supplied tool, and as you turn it, the cup works its way out along a ratcheting ramp, until you go one step beyond the position where the cup is as far out as it goes, at which point it jumps fully back into the interior of the piece. Since the base of this cup supports the bottom of the spring, this mechanism allows for fine-tuning the spring force, independently of the slack adjustment. This is moderately useful, however I think it is important to note that this mechanism permits just enough variation of the spring pre-compression to compensate for the variation caused by the slack adjustment, which is typically a small variation, except possibly when the slack is reduced to nearly nothing, and then depending on how carefully the center square piece was designed. At the other end of the slack adjustment range, it is difficult to discern the effect that this separate adjustment has on the rigidity of the cube. Swapping out the springs remains the only means by which it is generally possible for the owner to adjust slack and rigidity each independently of the other and according to personal preference. Given a choice between a cube with this innovative mechanism vs. a cube that includes extra sets of springs, I would hands down take the one with the extra springs.

Good explanation!!!!!!!!!!!! I always know there is a different between tensioning screw and changing spring, but not know exactly why!!! Wonderful!!!!!!!!

Great video dude, you got everything right, this was what I actually needed to show everyone why my GTS 3 is better than other cubes

Wow, you are so good at explaining. I mean i never knew what springs are for and the animations look very cool as well. Your videos are so helpful and full of information.

Thank you j perm, this is the answer I've been looking for!

Thanks JPerm. Youre the only one in You Tube who explained what the dual system does to a cube.

I could point out some mistakes in the physics, that no one cares about, but it doesn't matter. You got the point, and explained it perfectly. It was easy to understand, and very well illustrated. Nice video man :D

Great video. I *ABSOLUTELY* agree with everything you said! I had always been looking for a stable cube that could still corner cut well and be fast. The GTS3 has accomplishes this in super convenient way to adjust the tension of the cube and I love it. Ironically however, I still wasn't satisfied with my cube even on the 8th setting so I actually did end up having to swap the springs for MF3RS2 springs. (Apparently I like my cubes to have really strong springs) Now I just have it set on the 3rd setting and I'm absolutely loving it.

Great video. Thanks.

I always thought about this while tensioning my cube!

This video was a great overview of the physics of springs in the cube and how they work, but you should’ve mentioned the S6-S9 system of the Gans 356S V2. It was very overlooked and worked very good for customizing that cube, and S6 helped the stability of this cube, which is already very flexible.

Great video!

Very good video!!

The intro was very good!

When i first watched this vid i didnt really understand the physics explaination then i rewatched it and actually focused on it, it makes sooo much sense

5 years later, people are complaining about moyu not updating their compression system

Just had a discussion on Reddit. One thing you forget here is that when you click the adjustment thingie out, you are actually lifting the inside bottom of the center closer to the screw while compressing the spring. Now assume you could move the center out 3mm with setting 0, and setting 7 is 1mm further out. That means the center will be able to travel only 2mm. You could imagine the same without springs. The more you lift the inside of center, the shorter it will move. Now, a standard M screw like M2, M3 etc they have a pitch of 0.5mm - That means it will turn 0.5 mm in or out by one full 360 degree turn. If we assume difference between min&max click/setting is 1mm (looks close), then that is exactly 8 quarter turns on an M2 screw. And we have a clicks. So to have exactly the same distance on min&max on the side of the center closer to the core, you would have to turn as many 1/4 turns on the screw than you to on the adjustment thing. Then distance from core to underbelly of corner is the same. Imagine no springs. Then adjusting the click system out to where it touches the screw at setting 7 and you will have one distance from center. Then moving it to setting 0, you can pull the center 1mm further away from core. So from a physics point of view, the screw must be turned in unison with the click thing.

thanks, i learned a lot about cube physics

GREAT VIDEO !!!

Awesome one

I know some people might have been confused about the distance getting bigger but the spring decreases in size, which seems countertuitive but it just means the absolute valued distance from which the spring is at rest... great vid and think its a great innovation by moyu

Really great vidéo, thank you !

I watched this video 3 months ago when I started cubing and it seemed like a different language. Now I actually understand it!! Progress!!

Very interesting video I recently got into cubing so I appreciate all of your input. This system kind of reminds me of the shocks system on a car. I'm into Nitro RC so once you spoke about the spring settings it began to make alot of sense between the two hobbies granted we can both use silicone oil for the springs to aid with compression and reduce spring noise but its very interesting to see the comparisons between the two how they have similar effects. Stiffer for more bounce back and loose for easier movement. Great work J Perm, maybe dabble across some shock info on RC it might surprise you!

no cubes were harmed, I put the springs back in. the gts3 on the right still has crazy loose tensions though

I have an entire spring theory section in my GTS3 review where I tried to kept the spring force as constant as possible (ie the distance between the bottom of the spring compression system and the top of the screw, basically the x of F=kx, k never changes in my experiment because no spring swaps are involved) but I had the spring compression system first set at level 0 in the first part of my experiment and then level 8 in the next part, and there was a huge difference in corner cutting. I presented my point slightly differently, starting from the equation and then talking about screw tensions at a later point. Your spring theory video is much better than mine, much more detailed, all I did was put in the F=kx equation and compare the 2 extreme settings. 9:30, I just memorize my desired level of the spring compression system (level 4) and then compare the height of the screw head with the height of the blue plastic rim of the compression system (I keep them at the same height), didn't find it troublesome to set up at all. 9:48 I did the compressed spring mod to a bunch of cubes (BoChuang, MeiYu, ShengShou 8, YuXin Blue, but not yet to an WuQue), the ShengShou 8x8 and YuXin Blue turned out the best, especially the Blue since people would use thunderclap springs but I just permanently compressed the stock springs without having to hunt for thunderclap springs. I would probably do it to the classroom MF8 eventually. 10:51, I wonder if we put MF3RS2 springs or any stronger springs into the GTS3, the range that the compression system has to offer would sink into the green area and occupy less of the blue area. That defeats the whole purpose of overcoming the need to swap the springs, but if MoYu could make new batch GTS3s or simply do that in a future cube as the stock setting, it would be the next advancement for the spring compression system.

So about your corner cutting experiment, does it agree with what I said? Which is that screw depth has an effect on corner cutting while the spring strength is not really important. Someone commented about using mf3rs2 springs with success, I don't plan to try it since I like the highest setting already but yeah it's definitely a great idea that I didn't even think of when making this video!

@laiscube

6 жыл бұрын

I think it agrees. My experiment was about screw depth. I didn't understand screw depth at first, I just read MoYu's promotional material and they said "adjust the elasticity", so I went with their terms. But after watching your video, I think my experiment is actually the animation at 2:35 of your video but with a spring added, I just kept the spring force as constant as I can to make the experiment fair, and no one can blame the difference in corner cutting on it because I didn't change it. 2:35 is like the level 0 in my experiment and 2:40 is like the level 8. In my experiment, I pushed the spring compression system upward from level 0 to 8, and then tensioned the screw upward by the same amount, which is the screw depth, and then it improved the corner cutting drastically.

Anti-Ridge Club unite! But I do agree, the spring system was a great idea. Even better than the GES nuts from GAN.

Great video. My cube has that system and has no instruction or explanation of adjustment. Absolutely mind boggling why a product like this is boxed with no instructions.

Very usefull👍🏽

Not to be pedantic, but to clear up something that may be a bit confusing: In Hooke's Law, the "distance" is referring to how much it's moved from it's relaxed position (so you can increase the force exerted by the spring by compressing it OR by putting it under tension by pulling it apart). This video is great, but seemed a bit confusing to say the distance was increasing when compressing the spring with the new system. :)
