Ok, I need some help. I can build the first three layers. I know how to make the yellow cross on top. But then everytime I have two edges that heve two colors instead of one. Is there an easy way to switch the left face yellow/green with the right face yellow/red?

Try to pair all edges after having solved the centers, and then start doing 3x3 reduction. The only annoying things that could happen then are OLL and PLL parity.

You're looking for the middle case in the Pair Edges section.

About the parity cases in this file, I see 4 PLL parity images but only 2 algoritms. I don't get that. Right now I have only two corner pairity. How do I howld my cube and which algoritm?

 

[Kattenvriendin]

Can you show us a picture?

I assume by the way that the underside of the image is the front of the cube. What happens if you do the algorithm that way?

The four images are the main parity cases. Doing one of the algorithms brings the cube into a position that is solveable like a 3x3. Long story short, when you get to PLL, if you don't see a usual PLL case, do one of the parity algs and then solve the PLL.

[Endgame]

hold the bad corners on ULF and UFR

then
r2 U2 r2 Uw2 r2 U2 Uw2

now recognize the PLL case, it'll most likely be a T-perm

 

[MarcelP]

r2 U2 r2 Uw2 r2 U2 Uw2 ... Nope, sorry, that messes up the cube..

 

[Endgame]

r2 U2 r2 Uw2 r2 U2 Uw2 ... Nope, sorry, that messes up the cube..

then do it right and it won't

 

[ThomasJE]

r2 U2 r2 Uw2 r2 U2 Uw2 ... Nope, sorry, that messes up the cube..

Remember that r2 is the inner slice, not outer and inner layers; that's Rw2.

I have tried multiple times.. Now I just did:

(Rw2 R2') U2 (Rw2 R2') Uw2 (Rw2 R2') Uw2 and I think I have a 3 X 3 PLL case now..

 

[MarcelP]

Thanks man! I did not know about the r2 notation. I figured that was R2.. LOL

that's the algorithm i gave you but without cancellations

 

[MarcelP]

Thanks Nick.

Btw, I just did a real nice one on a brand new cube.

It's my new Type C V. Very nice cube. Not really fast yet but it feels like you have a lot of controle.

Nice! One thing - your OCLL alg was R U2 R2 U' R2 U' R2 U2 R. Try executing it as R U2' R2' U' R2 U' R2' U2' R with all the R's as one fluent 'back and forth' movement. Also, why don't you try reconstructing your own solves? It can be quite fun to watch your own moves on camera frame by frame. If you want any tips, Brest and chrissyD are two other well known reconstructors. A good place to start is by looking here. The only change is that instead of using Media Player Classic, Brest uses Avidemux now. Good luck!

 

[Kattenvriendin]

And fun.. Avidemux is free!

I use it too.. easy proggie

I am fiddling with the 4x4 now too.. forgot about the r2 and Rw2.

r2 = two quarter turns inner right layer
Rw2 = two quarter turns both right layers

^ Correct?

>.<

Now Marcel.. get a 7x7.. imagine the notation of that one.. LOL

 

[MarcelP]

Try executing it as R U2' R2' U' R2 U' R2' U2' R with all the R's as one fluent 'back and forth' movement.

I just can't do a double flick with my left hand. I know it sounds stupid bu I just can't

Also, why don't you try reconstructing your own solves?

I wish I could. But betwee 3 hours travelling to work, fulltime job, family with small children, night school there is only so much time that I can spend on cubing. It that time I rather cube than reconstruct.

Just a matter of practice
Your rapid improvement is a testament to "practice makes perfect"

What I do: R U2 R2 U' R2’ U' R2 U2 R

Executed as
R U2 – right hand
Now regrip with right hand: index/middle finger on UR edge, thumb on DR edge and keep them there for all three the R2’s “back and forth part”
R2 – don’t let go
U' – left index (
R2’ – don’t let go
U' - left index finger
R2 – now let go for the final part
U2 R - right hand

I suggest playing with the initial grip and direction of the R2’s and see what suits you best.

I can't do left double flick either. I do the same as Cubenovice except for the first R U2 I actually perform as
R U' (right hand... do U' with right thumb)
U' (left hand)

Nice! You're definitely getting faster, and your TPS and HTM are much better. Your first pair was quite slow; it should be around 30-40% of the whole F2L; it took 53.5%. So maybe try to improve on 1st pair lookahead.
