Is it possible to solve all jumbling after doing cubeshape? So the rest of the solve will be jumble-move free. Otherwise it would be really hard to come up with algs for the rest of the cube.
Well, it's definitely possible. All you need to do is make sure that each orbit has exactly one of each color. But I'm not sure how practical it is to try to see that. Still, it's an interesting idea. I might just try a solve that way now.Is it possible to solve all jumbling after doing cubeshape? So the rest of the solve will be jumble-move free.

I believe it is possible to have all center pieces in the correct orbits (or at least appear so) and still require jumbling to solve: if a single edge/center is flipped it can be fixed with UR+ FL+ UF FL- UR- FR+ UL+ UF UL- FR- UF. I don’t know another way to flip a single edge piece, but I’ve reached that position several times.Well, it's definitely possible.

I think you mean UR+ FL+ UF FL- UR- FR- UL- UF UL+ FR+ UF.I believe it is possible to have all center pieces in the correct orbits (or at least appear so) and still require jumbling to solve: if a single edge/center is flipped it can be fixed with UR+ FL+ UF FL- UR- FR+ UL+ UF UL- FR- UF.

But all the centers are in the same orbits that they were in before that algorithm. You’re right about switching two corners. My point is that I don’t believe there is a way to fix this position without jumbling:I think you mean UR+ FL+ UF FL- UR- FR- UL- UF UL+ FR+ UF.
But I wouldn't really consider that flipping the edge. That's swapping two sets of centers, plus an extra UF move. I say that because as is, you've also swapped two corners. If you leave off the UF, you have 4 centers that have swapped, and all the corners and the edge are still unchanged.
And dealing with those is as easy as doing that algorithm to fix it. And that is just a variant of what I was talking about before, where you have to convert a 2-cycle into a 3-cycle. Doing that algorithm essentially bypasses the need for it by swapping both. So technically, you were completely right - you do need jumbling to solve at the end. But it sure makes it easier to handle the end of the solve, at least from my perspective. Putting the pieces in the correct orbits at the beginning gives you a lot less restrictions so it's pretty easy to move them in. The only thing that makes it of questionable value is that it's hard to keep track of keeping all six colors in each orbit at the beginning.
I agree with your basic point (and I agreed with that in my previous post). But it still seems like there's a possible benefit to putting all the pieces in the right orbit before doing the rest of the solve, since the jumbling necessary at the end is pretty straightforward and easy. But I still doubt it would actually help someone who's really good at the puzzle.But all the centers are in the same orbits that they were in before that algorithm.

You’re right. Switching two corners can only be done with jumbling so you don’t see that in my pure PL4C alg list(corner aren’t effected by jumbling)My point is that I don’t believe there is a way to fix this position without jumbling.
I think I may have misunderstood your initial question.You’re right. Switching two corners can only be done with jumbling so you don’t see that in my pure PL4C alg list(corner aren’t effected by jumbling)
I actually wonder if such people exist right now XD. If such people do exist though, I would like to know whether my points are correct.I still have my doubts that anyone who was really good at the puzzle would find this faster than a more layer-by-layer solve.
No you haven’t. You are talking about exactly what I am asking for, which is center pieces effected by jumbling moves. I am asking that if there is a way to correct all center orbits, or even better, getting rid of all jumbling moves(you just proved that impossible)before solving the cube after cubeshape.I think I may have misunderstood your initial question.
This site recommends correcting all center orbits before the rest of the solve: https://www.jaapsch.net/puzzles/helicopter.htmNo you haven’t.

Do you have a flipped edge center(the piece with two small triangles on it) somewhere else on the cube?Hi, I'm new to the community. I have a problem with my first solve of the curvy copter and need a pll for two corners. The situation is weird and maybe you'll have a solution for this.
No, but during my solve one edge center fell out and I've put it back. Maybe I made a mistake there (I think it was the orange-white center piece).Do you have a flipped edge center(the piece with two small triangles on it) somewhere else on the cube?
Yes, that's the problem. Can you take the edge center DIRECTLY BETWEEN those two wrong corners out and FLIP it and stick it back?No, but during my solve one edge center fell out and I've put it back. Maybe I made a mistake there (I think it was the orange-white center piece).
Of course, done. What's the next step?Yes, that's the problem. Can you take the edge center DIRECTLY BETWEEN those two wrong corners out and FLIP it and stick it back?
Now just watch this video at 12:32 and this is the exact alg you need:Of course, done. What's the next step?
