Intelligented Default Bed-Mesh

Intention

You can slice your model once and then print it on any build-plate you want without having to reslice it

Installation

SSH into you pi and run:

cd ~
wget -O - https://raw.githubusercontent.com/LynxCrew/Intelligent_Default_Mesh/master/install.sh | bash

then add this to your moonraker.conf:

[update_manager intelligent_default_mesh]
type: git_repo
channel: dev
path: ~/intelligent_default_mesh
origin: https://github.com/LynxCrew/Intelligent_Default_Mesh.git
managed_services: klipper
primary_branch: master
install_script: install.sh

you also need to add

[save_variables]
filename: ~/database.cfg

to your printer.cfg

What it does:

You can persistently save which mesh you are currently using by calling SET_DEFAULT_MESH DEFAULT_MESH=<name>. If you call BED_MESH_PROFILE LOAD=default INTELLIGENT=1 TEMPERATURE_EXTRUDER={EXTRUDER_TEMP} TEMPERATURE_BED={BED_TEMP} FILAMENT_PROFILE='{FILAMENT_PROFILE}', instead of the profile called default, the profile you saved will be loaded together with a predefined z-offset for that profile, temperature and filament.

Config Reference:

[gcode_macro _MESH_VARIABLES]

Here you set the general offset to be applied for the given mesh name default: -0.1 would apply a z-offset of -0.1 if the mesh 'default' is loaded

[gcode_macro _TEMPERATURE_OFFSETS_EXTRUDER]

Here you can set different offsets for different Extruder temperatures The lowest temp will act as a lower bound (if the given temp is below that, the offset will still be used, so lets say you define 210: -0.1 and print at 200C, you will still get -0.1) Similar the highest temp will act as an upper bound If the printing temp is between two specified temperatures, the script will do a linear interpolation

[gcode_macro _TEMPERATURE_OFFSETS_BED]

Same as above, just for the bed

[gcode_macro _FILAMENT_OFFSETS]

Filament profile specific offsets, set the name of the filament profile as the key and the offset will be used when the profile name is passed to the command

[gcode_macro _MAX_BED_TEMPS]

Can be used to specify max temps for build plates and check them in start_print for example

Example usage:

[gcode_macro START_PRINT]
gcode:
  {% set BED_MESH_PROFILE = params.BED_MESH_PROFILE|default('default')|string %}
  {% set BED_TEMP = params.BED_TEMP|default(60)|float %}
  {% set EXTRUDER_TEMP = params.EXTRUDER_TEMP|default(215)|float %}
  {% set FILAMENT_PROFILE = params.FILAMENT_PROFILE|default('None')|string %}
  BED_MESH_PROFILE LOAD={BED_MESH_PROFILE} INTELLIGENT=1 TEMPERATURE_EXTRUDER={EXTRUDER_TEMP} TEMPERATURE_BED={BED_TEMP} FILAMENT_PROFILE='{FILAMENT_PROFILE}'
