What point i have to pick for M671?

Hi,

I am configuring the printer, and I am configuring the Homing, for this I have to enter the coordinates of the leadscrews... But I don't know what the exact coordinates are. there are two options, the linear rail coordinate or the pivot point coordinate.

I suppose that those coordinates will be on the point X=0 and Y=0, if I define it as the center of the bed, they will be on this point....

@peirof it’s the point the bed pivots around, so point B.
