Single Rod Achievement in The Talos Principle II

*MISSABLE*

Note that I have marked this achievement as missable because there have been reports that, if you don't do this on your first completion of this puzzle, resetting the puzzle and trying again won't unlock this achievement. To be safe, unless/until I have definitive confirmation that you can get this achievement on a reset puzzle, I highly recommend just doing this on your first time through this puzzle.

"Seesaw" is main puzzle 8 in E2 - Wooded Plateau.

This achievement wording is more straightforward: there are two connectors in this puzzle, and you need to complete it by only using one - doesn't matter which one. This can be tricky to figure out how to line up the lasers, but it's quick to do once you know how (obviously). See the video below for how to set up the connections and line it up.
