In Honkai: Star Rail's Alchemy Commission, you'll find a few Courier Cycranes that will reward you with coveted Chests if you manage to follow them to their destination. However, one of the Courier Cycranes on the first floor is broken, so you need to fix it by solving an Abacus Circuitry puzzle. If you're having trouble getting the modules to align correctly, follow my walkthrough below to solve it.

There are a few ways you can solve this Abacus Circuitry puzzle, but I highly recommend you follow this guide exactly as-is from start to end. You can click on the Reset button on the bottom left of the screen if you make a mistake.

Once that's done, click on the lowest green module, which will now also have an S symbol. Then, rotate clockwise two times so that all the symbols are aligned according to the second image above.
Click on the upper green module once again. This time, you need to rotate clockwise once so that the symbols shift positions. Reference the second image above for what it should look like at this point.
Lastly, click on the lower green module and rotate clockwise once to line up all of the computing modules in the correct positions. Doing so will complete the puzzle, and the Cycrane will finally be able to fly again. Don't forget to Investigate the Cycrane and follow it to its destination to receive a Bountiful Treasure reward.
