# # # Klipper Adaptive Meshing # # #
# Heads up! If you have any other BED_MESH_CALIBRATE macros defined elsewhere in your config, you will need to comment out / remove them for this to work. (Klicky/Euclid Probe)
# You will also need to be sure that [exclude_object] is defined in printer.cfg, and your slicer is labeling objects.
# This macro will parse information from objects in your gcode to define a min and max mesh area to probe, creating an adaptive mesh!
# This macro will not increase probe_count values in your [bed_mesh] config. If you want richer meshes, be sure to increase probe_count. We recommend at least 5,5.
