1) I measure the distance for the red led to light (3 mm for me)
2) I adjust the place of the sensor 3 mm higher than the hot end touching a A4 paper
3) I adjust the offset to be perfect basing on this https://build3dparts.com/wp/?page_id=551
I does not work so good to me, so I adjust it going back to z0 and counting the mm needed to be good.
