esamwise Hello, I hav ethe same issue.
My 3.0 BL Touch works, it does teh leveling, but it doesn't correct at all the plate level.
If one side of my bed is too low, for example 1mm lower than the 3 other sides, the print is KO on this side.
So the BL Touch can do an auto level, but it doesn't compensate the differences between the 9 points it has touched 🙁
