Last 2 Centers on BIG cubes

[hawkmp4]

By big, I mean, bigger than 5x5x5. I can efficiently solve the centers on everything up to a 5x5, but any bigger than that I get completely stuck on the last two centers, usually I only have 5 or so pieces that need to get moved over...but I can't do it. Are there any strategies for doing this? Or is the best advice you can give to bash my head against the wall until I figure it out for myself?

Most people basically use the 'Niklas' commutator: RU'L'UR'U'L'U. For the centers, you replace the Rs and Ls with the inner slices that the piece you need to replace.

So...what pieces does that target? I'm sorry but its kinda vague...

 

[masterofthebass]

Try it out and see what happen

Wow. I had serious issues reading that...its early. I missed a prime or two in there.
Thanks! That's incredibly helpful.

Edit:
Nevermind. Its not doing at all what I thought it would...are you sure you have that algorithm right?

 

[masterofthebass]

woops i'm sorry i have the last L an L'. It should just be L

Srry this is a super dead thread (8 years old...wow!) but I'm getting into big cubes more and the algorithm that you show works, but where do you put the centers that you want to swap?

Crazybadcuber does a variation of this in this video. I found it very helpful.

Sooo... how would you solve the 'edge-centers' ? Is there some special Niclass for that?

If by edge-centers you mean center pieces on the edge of the center, then that video should explain it. If you mean edge pieces near the center, you'll need to watch a separate tutorial on last 4 edges, CrazyBadCuber has a good one.
