Hi,

I just successfully solved 2^4 BLD with macros using MPUlt v1.06. A screenshot, the log file, and the macro-definition file can be found in this folder (I hope this link is permanent):

http://games.groups.yahoo.com/group/4D_Cubing/files/Nan%20Ma/BLD2_4/

I used macros extensively. I even included the setup moves in macros to avoid clicking mistakes. As a result, once memo is done, the solving was very fast. The memo time was ~24 min and the solving time was ~2 min. I had two pitiful DNFs before the success. In the first attempt I didn’t memorize the orientation of a piece correctly. In the second attempt I clicked a re-orientation macro when I should click a permutation macro in the last step.

I would like to thank Matt for his warning about the reorientation step. I’m sure you will make a BLD solve without macro very soon, if not already done one.

I had a breakthrough on my understanding of reorientation when I talked to Raymond Zhao. His suggestion was inspiring. I’ll hold the trick to avoid spoiling.

I agree that it’s more fun to figure it out yourself first, and considering BLD in 4D was certainly one of the more interesting experiences I have had with these puzzles. Can you tell me what systems you use for solving and memorising? Using a very basic system for either will hinder your attempts at 4D BLD, but neither do you need an advanced system. Personally on 3x3x3, I use 3-cycles to solve (mostly BH, which is fairly easy if you know how to use commutators), and letter pair images/journeys for memorising.

Firstly, make sure the twist speed is slow enough that you can easily follow the twists you make, and verify that every twist is what you intended. Secondly, if you need to reorient one or two pieces in place and think of doing it as CW or CCW from a certain viewpoint, make sure that its the same viewpoint you use for deciding which algorithm to use for the reorientation. I had 2 pieces left after placing all the pieces which were in place but misorientated with one sticker solved in each. I tried to rotate them the wrong way (I memorised and recalled correctly, but memorised it from the wrong viewpoint and therefore CW and CCW were switched), and then made a mistake in the algorithm by doing one of my twists in the wrong direction and didn’t notice. I guess I was out of practice a little, but that’s no excuse. Next attempt should be a success at last, unless I make any more silly errors.
