Let me preface by saying I don’t know a lot about coding in Python (or whatever language Klipper macros are written in) and have basically learned what I know based on the existing macros in the config file. Using this knowledge, I am trying to create a custom macro for bed mesh calibration that uses the Marlin and RRF G29 command with a few parameters. The problem is that I get an error message when trying to parse the second parameter of the command and I need assistance. I’ve tried passing the parameter with “=”, double quotes, and single quotes, but none of them seem to work. The latest revision of the macro definition is listed below, so any help will be greatly appreciated:
[gcode_macro G29]
variable_mesh_state: -10
variable_mesh_profile: "none"
# Command formats:
# G29: Calibrates bed mesh and saves it under profile name ratos
# G29 S-1: Clears bed mesh
# G29 S0: Same as G29
# G29 S1 P'Profile Name': Calibrates bed mesh and saves it under chosen profile name
# G29 S2 P'Profile Name': Loads Bed mesh profile
# G29 S3 P'Profile Name': Removes specified bed mesh profile
gcode:
{% set x_homed = 'x' in printer.toolhead.homed_axes %}
{% set y_homed = 'y' in printer.toolhead.homed_axes %}
{% set z_homed = 'z' in printer.toolhead.homed_axes %}
{% if params.S is defined %}
{% set mesh_state = params.S|default(-10)|float %}
{% endif %}
{% if params.P is defined %}
{% set mesh_profile = params.P|default('none')|replace("'", "") %}
{% set decoded_msg = "Mesh Profile Name: " ~ mesh_profile %}
RESPOND MSG={decoded_msg}
{% endif %}
{% if mesh_state == 3 %}
{% if mesh_profile != 'none' %}
RESPOND MSG={mesh_profile}

{% else %}

{% else %}

{% elif mesh_state == 1 %}
{% if mesh_profile != 'none' %}

{% else %}

{% endif %}

It’s not clear how you’re trying to call this macro. The comments at the beginning of the macro about command formats aren’t correct as macro parameters aren’t passed like S1, it would have to be S=1.
I was able to work around the error by renaming the macro to CALIBRATE_MESH instead of G29 and using full names for the parameter variables (STATE and NAME) instead of single letters like S and P. For some reason, using single letter parameters only captures a single character when that parameter is provided (so if I provide parameter P as P’Hot’, it only captures the first single quote as the parameter value. When I try P=Hot, it captures the = as the value). Also, using G29 as the macro name does not seem to work no matter what the parameter variables are called, even though Klipper natively does not have G29 implemented.
My new macro now also includes adaptive mesh leveling, so this one macro handles all the bed mesh leveling requirements when I call it in my rather complex START_PRINT and END_PRINT macros, based on how I slice my print.
The new macro is listed below:
