Can I have bending correction with BED_LEVELING_METHOD = 1 and GRID_SIZE = 2 ?
I've read that you can make use of bending correction (ABC) only with the 3 measurement points.
But I'd like to confirm if it is exclusive of this method or I can apply it for a grid = 2 (four measurements points).
Bending correction creates a correction plane that is build with a plane going through the 3 z-probe points. But it can be used for any measuring method. Just be aware that it is a plane. So if your bed rotates around a middle axis it will not work. Only if it bends the more you go to outside like these cantilevered beds.
