Learning Petrus (but stuck?)

[hiitsaaron]

So I'm learning Petrus. Just got it down to solving the FTL, then I'll work on 'the rest'. I'm just solving the FTL, and getting my speed up, but at the moment I'm stuck here:

The focus here is putting the yellow-purple-blue corner (L, top left), with the blue-yellow face (F, top middle). Now, there were no bad edges.. however it wouldn't work if I did the algorithm F U2 F' (from the position pictured) as the blue-yellow face is now inverted.

What would I do in a situation like this without starting all over again?

Need better pictures. Very hard to see what you're talking about.

Is there somewhere online I can like set a rubik's cube so you guys can see it?

Thanks, but what is 'y'?

 

[hawkmp4]

y is a rotation in the direction of U. So y' is in the direction of U'.

Ahh, so spinning the whole cube clockwise. Thanks!

Ok, so it happened again. Is there a reason why this is happening? I could just remember the algor., but it's happened twice now, and I wanted to cut down on my time. Haha.

Can we get better picture now?

So the issue you're having is that the corner is pointing up in the U face, correct? That is, pink is your D face color, and you have a corner that belongs in the D face with pink on top on U? Er.. purple. Looks pink in the picture.

If I'm getting this correctly, then you'r EO isn't done. All cases should be solvable with only R U moves.
We really need to see this better ;-;

 

[hiitsaaron]

Ok. I'll explain better: I'm rotating the F face (red arrow), so the yellow blue piece sites in the bottom half of the green dotted area. Then I'll rotate the U face twice, so the yellow-blue-purple sits in the top half of the green dotted area, so now they are a pair.

Then I'll take them and place them into the blue dotted area to complete my F2L.

However, the problem is that the yellow-blue middle piece is inverted, so I can't do this. I've had this problem a few times now, just wondering how to avoid it, or if it's a common problem that I haven't heard about.

Thanks.

Er.. purple. Looks pink in the picture.

Yeah, sorry. I'm using purple and pink interchangeable.

Yeah, just as I thought, your EO isn't done.

I'm not sure what EO means?

The bad edges step. You're not done with it.

 

[poorshooter]

eo should be edge orientation.
step 3 of petrus, turning (or orienting) bad edges into good edges

is this where you're having trouble with?

Oh ok. That would make sense. What I recall as 'fixing all bad edges', is that you are able to make 2 crosses.. say you had white and blue faces 'free', all edges with respective colours would be 'touching' the middle piece..

Or have I got that wrong?

1. Don't bump.

2. basically yes. go here: http://lar5.com/cube/fas3.html

Why are people so picky about bumping on these forums?

 

[Kirjava]

People only care about bumping if you're not contributing anything worthwhile to a thread.
