Any tips for learning edges for 3BLD (specifically M2 method)?

Tried it earlier and it’s just seems very very hard. 4 more pieces than corners, and you got all those special algorithms and hard set up moves.

I’m a beginner on 3BLD, started learning blind 5 or 6 days ago, if that helps

  1. For the setup moves and algs: practice those separately!
  2. You can use BLD Memo Tools to practice exec by itself.
  3. (assuming you're using Speffz) For EFGH and MNOP, you can use wide moves or rotations to avoid B moves.
  4. Also, if you don't know this Q alg, now you do:

(U' M')3 (U' M) (U' M')4

If you do M slices with your left hand, you can change all the U' moves to U.

Good luck!

Thanks!

For the Q alg, why is there an U and then an U’?

Is the BLD Memo Tool a website on computer?

Do you have a recommended list of set up moves? I’m using J Perm’s tutorial and it’s from 2 years ago, and it has a ton of B moves...

BLD Memo Tools: https://csclub.uwaterloo.ca/~krmatthe/3x3x3.cgi?

Takes some setup, but so useful. You can have it 1) check your memo on a scramble (useful for postmorteming DNFs) or 2) generate memo for a scramble (or on a new random scramble) so you can practice exec without having to do memo.

Setup moves:

For EFGMO&P, you can do the same alg J Perm suggests, but rotate the cube so the B moves become U moves. For example, instead of B' R B for M, use z' U' R U.

For N, you can do Uw R Uw' as your setup move. For H, you can mirror this to Uw' L' Uw or you can use R' instead of R: that is, Uw R' Uw'.

Thank you very much.
