RS3 M Core Screws Coming Out?

[Brandonius]

I got a Moyu RS3 M 2020 yesterday, and I'm loving it. It clicks with my turning style like no other cube has, and is easily going to be my main. However, something annoying has been happening lately. 3 times now, as I'm turning the cube, the screw inside the red center that attaches it to the core of the cube has come out! I managed to catch this on video (it's an mp4 - not sure how to share it), and I'm wondering if anyone has advice. The screw isn't stripped out, which leaves me to believe the problem is with the core.

I also saw that a few people on the cubicle mentioned they had this same problem. I'm hoping there is a workaround because the cube is incredible. Is there another core I can substitute, is anyone else having this problem?

Thanks for any help

Not sure, make sure to check that the screw isn’t getting stuck inside the centre when turning, and in that case, it’s a stripped core
. Either try get a replacement from your local shop or try blu tacking or something

I think I might have the same issue, on the red side too no less. I emailed The Cubicle to see what they could do.

STRIPPED CORE SOLUTIONS: I think this is what u have

Solution 1 (Recommended)

1. Get a plastic Bag
2. Cut a 2x2 Square
3. Unscrew the loose side
4. Screw it back in with the plastic bag covering the screw’s threads

Solution# 2

1. Unscrew one side
2. Put a small toothpick in the hole.
3. Cut the part of the toothpick that is sticking out from the hole
4. Screw the screw back in with the toothpick still there

If you still dont get it, I can post a video online and give you the link later.

Can you please upload your video in google drive, make it public, and share the link with us so we have more knowledge of the problem?

my rs3 2020 doesent have this problem so idk

I wanted to say that I lubed the core with traxxas 50k and the red side which is the one that loosened has lube all over the center cap. Maybe the lube leaked down and loosened the screws? Honestly I'm not sure what's going on in that center.

My only other cube to have this core issue was the MF3RS, which interestingly enough is in the same line.

Did you try the plastic bag trick?

I personally haven't had this problem with my RS3M 2020, but I have had a similar problem with my Gan 354M. After turning the white face, the ges nut would slowly come out. The only solution I found was to tighten the ges nut more than I usually would, so if you don't mind a tighter cube, that could work.

I got a replacement core from cubicle being delivered

Yes I tried tightening my cube as a whole and it seems this has mostly prevented the loosening. Well for now, idk how it'll hold up after many solves

Another reason I am with the cubicle
did you know rick astley only made 12$ off of rickroll in 2010 because someone elso wrote it for him?

I tried the plastic bag trick and it seems to work. However my yellow side is also falling off. I mean the yellow side will loosen and the whole layer will pop off in a massive cube explosion. It's crazy

I've been trying to figure out why the RS3M 2020 has such bad spring noise, and I noticed that the springs seem to go "crooked", that is they're not perfectly vertical due to their large diameter. Combined with the fact that the springs have a large diameter about the size of the screw head, the end of the spring actually rubs against the side of the screw head instead of the bottom like normal. I think this could've been avoided by choosing springs with a smaller diameter.

You can see what I'm talking about in this picture on the left side of the screw head. The spring does not stay centered.

I have crooked springs too yet it works fine

Having the center caps on kinda muffles the sound. Maybe I should just fill my center pieces with cotton balls to muffle the sound lol

That does actually work with normal pieces to make a cube quieter, not sure about pieces with moving parts inside...

I got my replacement core and I still have this issue

Maybe I should just do the grocery bag / teflon tape thing because it worked the last time I used it

Moyu and tesla are quite alike. They offer awesome products for cheap prices, but they have factory quality control problems.

since when is tesla cheap?

 

[SH03L4C3]

not cheap, but they are working on a good electric car for only 25000.
Moyu made the RS3M

One solution to prevent core stripping.
