I know that, by now, almost all endgame crafters already have a 100% rotation that they like for one-star crafts, but I wanted to share mine anyway. Even though I have max melds, the new accessories, and all Artisan tools, 95% of my crafts are one-star items (or i45-49, which is similar). So, I wanted a one-button macro that would succeed 100% of the time with no food, even with a Poor condition on Byregot's Blessings, so I wouldn't have to pay attention at all when crafting (previously, my 100% macro was 17 steps, requiring two macro buttons, and it was only ~90% on a Poor condition Byregot's).

Using a crafting simulator, this rather odd macro was the most optimal one I could come up with that was only 15 steps:
  1. Inner Quiet
  2. Steady Hand II
  3. Basic Touch
  4. Innovation*
  5. Basic Touch
  6. Basic Touch
  7. Advanced Touch
  8. Great Strides
  9. Steady Hand
  10. Ingenuity/Ingenuity II**
  11. Advanced Touch
  12. Great Strides
  13. Byregot's Blessing
  14. Careful Synthesis II
  15. Careful Synthesis II

* Innovation is here because I could not fit it later. Using one Steady Hand and one Ingenuity for both final touch actions was difficult to arrange, and the simulator I was using showed that Ingenuity increased the touch actions far more than Innovation would. If I moved the Innovation to just before the Steady Hand, it would buff the Advanced Touch, but that was less of a gain than hitting the three earlier Touches. So, oddly enough, this placement was an optimal way to eke out as much Quality as possible without spending Durability.

** Ingenuity was good enough for me when I first made this macro. I was getting 101 progress with Careful Synthesis II under Ingenuity, and I could make it with my 348 CP. Then, when I made and melded my Demimateria equips, my CP shot up enough (by 6) that I could switch Ingenuity for Ingenuity II. The advantage to Ingenuity II is it saves me a cross-class skill slot so I don't have to juggle skills between three-star and non-three-star crafts.
