AUX schemtics

[SGr33n]

Hi, I just figured out that the 2 pices pcb have a different pin names for AUX connector. 1 picece: G S AG 2 pieces: G A1 AG

Now I'm using the 2 pieces and I have to connect the X Endstop Switch, but the readme tells I have to use G and S. Would it be the same with A1 in place of S on the 2 pieces board?

Thanks!
