-> **NOTE:** Ideally, the magnets should be inserted to have opposite polarity, that is to say if you were to remove the magnet mounts and hold them opposite each other, they should attract one another without attempting to flip orientation. Mounting them differently has been a source of issues in the past.
+> **NOTE:** The magnets should be inserted to have their polarity aligned, that is to say **if you were to remove the magnet mounts and hold them opposite each other, they should attract one another without attempting to flip orientation**. Mounting them differently may cause cross-axis interference, which can (and probably will) lead to erratic stick behavior. The NaxGCC firmware is especially sensitive to this.

 - If after the measurement phase is done, the stick output is backwards on one or both axes, you probably were trying to make the stick _output_ match the other stick, instead of moving the physical stick into the notch indicated by the other stick. Mash `A` a bunch to finish the calibration and start again.

+- If after the measurement phase is done, your stick does not perfectly move between `-100` and `100`, but instead seems to be somewhat offset (either vertically or horizontally), you may need to ensure that the magnets you're using are mounted to have their polarity aligned. Consult the [magnet mounting](./assembly.md#magnet-mounting) section of the hardware assembly guide for more information.
