I've been trying for a long time to configure the BLTouch correctly on an Ender 3 and I only get results that have no sense. I already have another Ender 3 with a BLTouch configured that works fine. But this is giving me this mesh:
How is it possible that the corners are fine and the center is not?
Also, printing with that mesh I get these results:
The correction does not even correspond to the mesh. I try to align correctly BLTouch with nozzle, change wires, adjust screws... Any ideas?
