[Help Thread] Roux Discussion and Help

Thanks, I will check out those links.

I guess the other thing I need to do is set aside some time to just play with block building in an untimed fashion so I can just casually browse around for pairs and how to join them.

This is also a very good (if not an excellent) block trainer:
http://cubegrass.appspot.com/block_trainer/
(If you don't work with those colors, just turn your cube before).

I can see in the javascript this line where it would be easy to adjust the color scheme:
var color_scheme = {"U": "#FFFFFF", "F": "#00FF00", "R": "#FF0000", "B": "#0000FF", "L": "#FF8000", "D": "#FFFF00", " ": "#808080"};

But, even if I copy down the html and javascript files it makes a call to an external get_block.php which I have not been able to figure out how to get access to. Does anyone know who maintains this page? It would be quite a bit more useful to the community if you could work with your own color orientation and this should be pretty easy to do.

Edit: Ah, nevermind. I got it working. If you want to host your own version of block_trainer with your personal color orientation, here's what you do:

1. Download the 3 files - block_trainer.html, block_trainer.js, and jquery.js and put them in a directory together.
2. Edit block_trainer.js and make two changes:
2a. Change this line:
var url = "get_block.php?levels=" + levels_list + "&block=" + block_suffix;
to this line (which adds the server address to get_block.php since it's not local):
var url = "http://cubegrass.appspot.com/block_trainer/get_block.php?levels=" + levels_list + "&block=" + block_suffix;
2b. Edit the color_scheme line to your personal tastes. This is the way it comes, with white on top and green in front:
var scheme = {"U": "#FFFFFF", "F": "#00FF00", "R": "#FF0000", "B": "#0000FF", "L": "#FF8000", "D": "#FFFF00", " ": "#808080"};
And this is changed to what I'm currently using with blue on left and yellow on top. It seems that a lot of Roux users put blue or green to the left:
var color_scheme = {"D": "#FFFFFF", "R": "#00FF00", "F": "#FF0000", "L": "#0000FF", "B": "#FF8000", "U": "#FFFF00", " ": "#808080"};

You're done! Now just open the block_trainer.html in your browser and enjoy.

Just as a simple question, is it better to use a short alg with rotations or a slightly longer alg with no rotations? (Eg the H4 CMLL vs the equivalent case in CLL or COLL)

depends on the alg. I know this is roux, but G-perm (R U R' y' R2 u' R U' R'U R' u R2) Or F U F' L2 u' L' U' L U L u L2. Which is faster? Depends on the alg and your personal preference
 
After finishing learning EG1 for 2x2, I decided it was time to fix up my CMLLs. While I was at it, I thought that I might as well learn an eo preserving and flipping alg for each. Most of them, as guroux said, are just an added M move at the beginning and end (usually cancelled into r and r'), but for others, I learned new no flip CMLLs or nice COLLs. The one I am stuck at is F 3sexy F'. I cannot find any way to efficiently make this case flip edges. Its an L4C case ***....
 
Got my first sub-30 average of 12 last night practicing Roux blocks, twice. This is just for the blocks stage, not the whole cube.
 
With Roux I average around 20-22 seconds, and I am almost at that sub 20 mark. Could anyone perhaps tell me what I need to improve on? Thanks. Here are my splits:
First Block: 3-4 seconds
Second Block: 7 seconds
CMLL (I know most of CMLL, but not all.): -2 seconds
LSE: mid 5 - low 6

If someone could give me a few tips, that would be great! :)

also, these 3 cases:
R U2 R’ U’ R U R’ U’ R U R’ U’ R U’ R’
l’ U’ L’ U R U’ L U x’
R’ U2 R’ D’ R U2 R’ D R2

your splits should add up to your average, so you have to count recognition time with it. but from what i can see, cmll is probably your best step. you should work most on second block and lse.
 
First block Ao12: ~5.64
Second block: ~6.61 (although there would probably be observation even though I tried to avoid it)
F2B:~12.95
2B inspection:~1
CMLL: ~4.44
LSE:~5.14
CMLL+LSE: ~9.72
CMLL+LSE inspection: negligible
Total inspection time: 2.04 (worked out by deducting from my ao50- i averaged around 23/24 when I took these.

Note: I don't know full CMLL so I'm working on that.

My typical tps is around 2.5. Fastest I ever go in a solve is 5.

So, what should I work on next?

2.5 should be the tps of a 20 second solver. and 5 tps is that of a 10/sub10 second solver. idk how fast you are, but i suppose the first thing to do is make sure your not using useless moves. 50 stm on average is a good goal i think.

50 moves is pretty unrealistic for a 20 second solver, i don't think i do 50 in a speedsolve.

I am a 23 second Ao50er (my signature is a liar) although my global average is likely more like 21-22 (but sometimes I just screw up so some). I usually average 55-65 STM during a speedsolve (apart from H-cases and headlights i still use 2-look CMLL) and about 2.5 tps. The highest I ever think I held during a speedsolve was something like 4-4.5 during my 14.56 ex-PB (This is still my full step PB) but, for obvious reasons, i consider this to be somewhat of an anomaly.
 
Apologies if this is the wrong place for this, but long story short a friend pointed me to Roux when I said I wanted to learn how to solve a 3x3 and I wasn't able to pick it up at the time. Now that I have loads of free time I'm trying to learn again but I get stuck at Step 3. I've mostly been following Waffle's guide, though I've also referenced others, and I always seem to find myself not in any of the 7(?) corner cases. I try applying different algs just to see where they get me and one corner is always off. I also make attempts on my brother's cube (not that he knows how to solve them either) and I always end up with one corner off and I doubt we coincidentally broke and reassembled our cubes in the same way. I don't have enough intuition right now to try and orient the last corner correctly without messing everything up.
Here are pics of a current attempt. https://imgur.com/a/kLnhQ
I'm sure I'm overlooking something incredibly simple. Thanks in advance.
 
Your cube has in fact been reassembled incorrectly. You can either take it apart and reassemble, or twist the FLU corner so that blue is facing up, and then manually swap two corners that are diagonal from each other

EDIT: actually just do the twist

that's impossible case, you must have accidentally twisted one of the corners.
