When printing large or multiple objects on my MINI, I always find the outer corners of the bed the have the filament sticking less or not at all to the bed than the middle of the bed. I believe it has something to do with the small 4x4 bed leveling grid on the mini which makes the offset between points larger than what is applicable with the bed leveling. It would be good if there could be an option to change the bed leveling to a larger grid like the MK3 which has 5x5 and 7x7.

Describe the expected functionality
An option in a menu that changes the mesh bed leveling grid to a larger size for more precise and accurate mesh leveling. Changes the default 4x4 to 5x5 or 6x6 similar to the MK3

good idea man, has anyone picked up on this ?

I agree.
Prusa, please, for the love of all that is holy, fix the bed leveling.
I am having the same problems as DhruvMada05, the outer perimeter of the bed has horrible issues with the PETG filament sticking to the bed.
Its driving me absolutely insane and makes the printer useless.
