[Grbl_Esp32 Issue#493] Squaring support with multiple limit pins… how?

I understood that squaring is interesting if you have a double gantry system. What I basically did:

1. Put 4 axis on my board
2. Wired 4 limit switch pins on my board

Now, what I want to do is assign an X-Y-Y2-Z configuration. So I defined Y DIR/STEP and Y2 DIR/STEP.

#define USEGANGEDAXES
#define YAXISSQUARING

Next, I set the homing mask to:

#define HOMINGCYCLE1 ((1<AXIS)|(1<AXIS))

What I understood would happens is that when you home, both limit switches for Y and Y2 would eventually get hit… So, I tried to configure that:

#define YLIMITPIN GPIONUM32
#define Y2LIMITPIN GPIONUM35

To my surprise, doesn’t seem to be how it works… What is the proper way to do this?
