Klipper Adaptive Meshing & Purging is an extension that allows you to generate a mesh only in the area you really need it: where you print!

Since the mesh area will be smaller, the mesh can be much more dense. Imagine making a 3x3 mesh, but the size of a 3DBenchy!

KAMP also works if prints are started directly through the printer screen by checking the Calibration box before starting printing.

More info about KAMP here: Github


Note: This procedure must be repeated if you update the firmware or if you restore the printer to default settings.


Installation

  • Make sure you have followed this Installation Helper Script section before.

  • In the script, enter in [Install Menu] by typing 1 and validate with Enter and install Klipper Adaptive Meshing & Purging:


Configuration

  • Open moonraker.conf file:

    • On original Fluidd Web Interface go to Configuration icon on the left side.
    • On original Mainsail Web Interface go to Machine tab on the left side.

  • Search [file_manager] section and change value of enable_object_processing setting to True like this:

    # Set to 'True' if you use KAMP
enable_object_processing: True

  • Then, click on SAVE AND RESTART button in the top right corner.

  • Open printer.cfg file and add this line to enable KAMP:

    [include KAMP_Settings.cfg]

  • Then, click on SAVE AND RESTART button in the top right corner.

  • Open gcode_macro.cfg file, search macro named [gcode_macro START_PRINT] and:

    • Replace CX_PRINT_LEVELING_CALIBRATION command by these: 
      BED_MESH_CLEAR
BED_MESH_CALIBRATE
    • Replace CX_PRINT_DRAW_ONE_LINE command by these: 
      SMART_PARK
M109 S{extruder_temp}
M190 S{bed_temp}
LINE_PURGE

    Like this:

    [gcode_macro START_PRINT]
variable_prepare: 0
gcode:
  WAIT_TEMP_END
  CLEAR_PAUSE
  {% set g28_extruder_temp = printer.custom_macro.g28_ext_temp %}
  {% set bed_temp = printer.custom_macro.default_bed_temp %}
  {% set extruder_temp = printer.custom_macro.default_extruder_temp %}
  {% if 'BED_TEMP' in params|upper and (params.BED_TEMP|float) %}
  {% set bed_temp = params.BED_TEMP %}
  {% endif %}
  {% if 'EXTRUDER_TEMP' in params|upper and (params.EXTRUDER_TEMP|float) %}
  {% set extruder_temp = params.EXTRUDER_TEMP %}
  {% endif %}

  {% if printer['gcode_macro START_PRINT'].prepare|int == 0 %}
    {action_respond_info("not prepare.\n")}
    PRINT_PREPARE_CLEAR
    CX_ROUGH_G28 EXTRUDER_TEMP={extruder_temp} BED_TEMP={bed_temp}
    CX_NOZZLE_CLEAR
    ACCURATE_G28
    BED_MESH_CLEAR
    BED_MESH_CALIBRATE
  {% else %}
    PRINT_PREPARE_CLEAR
  {% endif %}
  SMART_PARK
  M109 S{extruder_temp}
  M190 S{bed_temp}
  LINE_PURGE

    Note: In case you don't define acceleration values in your slicer, it's necessary to add this command under the line _LINE_PURGE to load the default acceleration from the printer.cfg file:

    SET_VELOCITY_LIMIT ACCEL={printer.configfile.settings.printer.max_accel}

  • Then, click on SAVE AND RESTART button in the top right corner.

  • Open the moonraker.conf file and enable this lines by removing # before (or add this lines if you don't have them) to have future updates, like this:

    # Remove '#' from the lines below if you use KAMP
[update_manager KAMP-for-K1-Series]
type: git_repo
channel: dev
path: /usr/data/KAMP-for-K1-Series
origin: https://github.com/Guilouz/KAMP-for-K1-Series.git
primary_branch: main
is_system_service: False

  • Then, click on SAVE AND RESTART button in the top right corner.

  • Also make sure Label Objects setting is enabled in your slicer.

    • For OrcaSlicer: In Others tab, check Exclude objets setting
    • For Creality Print: Under Parameter Config, check Exclude Objets setting in Experimental tab

  • It's done. You have now Adaptive Meshing when printing starting, the hotend which is parked next to the printing area during heating and the optimized purge line next to the printing area.


In case you use Prusa Slicer, it's also needed to add more macros in your gcode_macro.cfg file:

[gcode_macro DEFINE_OBJECT]
gcode:
  EXCLUDE_OBJECT_DEFINE {rawparams}

[gcode_macro START_CURRENT_OBJECT]
gcode:
  EXCLUDE_OBJECT_START NAME={params.NAME}

[gcode_macro END_CURRENT_OBJECT]
gcode:
  EXCLUDE_OBJECT_END {% if params.NAME %}NAME={params.NAME}{% endif %}

[gcode_macro LIST_OBJECTS]
gcode:
  EXCLUDE_OBJECT_DEFINE

[gcode_macro LIST_EXCLUDED_OBJECTS]
gcode:
  EXCLUDE_OBJECT

[gcode_macro REMOVE_ALL_EXCLUDED]
gcode:
  EXCLUDE_OBJECT RESET=1
