# # # 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.

### This section allows control of status LEDs your printer may have.
variable_led_enable: False # Enables/disables the use of status LEDs in this macro.
variable_status_macro: 'status_meshing' # If you have status LEDs in your printer (StealthBurner), you can use the macro that changes their status here.
### This section configures mesh point fuzzing, which allows probe points to be varied slightly if printing multiples of the same G-code file.
variable_fuzz_enable: False # Enables/disables the use of mesh point fuzzing to slightly randomize probing points to spread out wear on a build surface, default is False.
variable_fuzz_min: 0 # If enabled, the minimum amount in mm a probe point can be randomized, default is 0.
variable_fuzz_max: 4 # If enabled, the maximum amount in mm a probe point can be randomized, default is 4.
### This section is for configuring a mesh margin, which allows the probed mesh to be expanded outwards from the print area.
variable_margin_enable: False # Enables/disables adding a margin to the meshed area to pad a mesh out for specific needs, default is False.
variable_margin_size: 5 # Size in millimeters to expand the mesh outwards from the print area in all directions.
### This section is for those using a dockable probe that is stored outside of the print area. ###
variable_probe_dock_enable: False # Enables/disables the use of a dockable probe that is stored outside of the print area, default is False.
variable_attach_macro: 'Attach_Probe' # Here is where you define the macro that ATTACHES the probe to the printhead. E.g. 'Attach_Probe'
variable_detach_macro: 'Dock_Probe' # Here is where you define the macro that DETACHES the probe from the printhead. E.g. 'Dock_Probe'
### This section is for those who are using Moonraker's Update Manager for KAMP, or want a more verbose macro. ###
