Block building. My move count is quite high, and I end up placing on edge and finishing the block with pairs, CFOP style.

I kinda use ZZF2L for blockbuilding.

First Block
z2 y' U D R' F' R D' inserting edge, removing pair, inserting pair. | You just have to add an edge: z2 x D' M' D
y M2 F M' F2 L F' L2 pair + insert | often it is better to build the pair at a position, where you are able to insert it with one move: y U2 F' R U'

Second Block
R' U2 R U M U' M' U' first pair + insert... | try to combine M and R moves: U r' U2 r U'
R2 U M U' M2 U2 r U r' second pair + insert. | You can bring corner and edge in a better position with: R' U' R' and insert with U' R U R'

CMLL
2-Look, Nothing to say

LSE
Would have done same here


My First Block for that configuration:
z2 x D' M' D M U' R B' (7)

Do you guys have a specific way to do blocks every time or is that just stupid?

Not really; more like specific ways to do certain situations, like pairing up corners with edges. See this for example:
http://grrroux.free.fr/method/Step_2.html

Of course, these are all intuitive during the solving, and not pre-learned.

What is moo? i have heard of it a few times but i have no idea what it is.

 

[kcl]

What is moo? i have heard of it a few times but i have no idea what it is.

M' U M if I'm not mistaken. I use M' U' M just because I do m slices with my right hand..

oh, i see. moo is just the M'/M U/U' M'/M that you do to finish orienting the edges.

Impossible cases - the number of swaps must be even, correct?

So I was checking out Roux, coming from CFOP, and I got to L6E and I was totally stuck. A little bit of intuition and a few slices later, and I had all but 2 edges solved. Particularly, the UF and UL edges.

The edges were NOT oriented correctly, nor were they correctly permuted (as previously stated). My question is, since the laws of cubing dictate that there can only be an even number of swaps, how can only 2 edges be be switched? Does it have to do with the edges being oriented incorrectly?

Also, note that the cube was not tampered with (i.e. no twisted corners, edges, etc.) I know this because after I took a picture of the cube, I scrambled it and solved it.

Thanks for any answers!

You didn't roux correctly...

Also, it might be that you had one block wrong somewhere, but still looking correct because of having the same color piece in.

Yes, the number of swaps is always even, would you mind showing us the picture?

If the cube didn't pop, then what you described did not happen.

 

[YddEd]

For the Roux part..
When the UF and UL edges do this = U M' U M' U2 M' U M'
I put the edges in UB and UL which would mean I would do M' U M' U2 M' U M'

Two flipped edges, nothing weird about that -.-

These are flipped edges, or mis-oriented edges. So, this is not an impossible case, you did Step 4a) wrong in Roux, when you didn't oriented all the edges correctly (or mixed up the orientation in a later step).

"since the laws of cubing dictate that there can only be an even number of swaps" - this is true, although, your case is not a swap of two pieces. It's a flip of two pieces.
See: http://www.speedsolving.com/wiki/index.php/Laws_of_the_cube
You confuse Rule 1 with Rule 2.
