Dann such mal in den Configs nach: [bed_mesh]
#mesh_min:
# Defines the minimum X, Y coordinate of the mesh for rectangular
# beds. This coordinate is relative to the probe's location. This
# will be the first point probed, nearest to the origin. This
# parameter must be provided for rectangular beds.
#mesh_max:
# Defines the maximum X, Y coordinate of the mesh for rectangular
# beds. Adheres to the same principle as mesh_min, however this will
# be the furthest point probed from the bed's origin. This parameter
# must be provided for rectangular beds.
