Trying to use your macros.cfg, but every time i get Move exceeds maximum extrusion (1.011mm^2 vs 0.640mm^2). I use CURA. What should i do? Thank you!

You can add this to your extruder section in the printer config.

max_extrude_cross_section: 5

hello, to avoid pass over to negative positions, I edited Line_Purge.cfg, macro.

`
gcode:

{% if display_parameters == True %}
  { action_respond_info("adaptive_enable : %d" % (adaptive_enable))  }
  { action_respond_info("z_height        : %f" % (z_height))  }
  { action_respond_info("purge_amount    : %f" % (purge_amount))  }
  { action_respond_info("line_length     : %f" % (line_length))  }
  { action_respond_info("flow_rate       : %f" % (flow_rate))  }
  { action_respond_info("x_default       : %f" % (x_default))  }
  { action_respond_info("y_default       : %f" % (y_default))  }
  { action_respond_info("distance_to_object_y : %f" % (distance_to_object_y))  }
{% endif %}

{% if adaptive_enable == True %}
    {% set all_points = printer.exclude_object.objects | map(attribute='polygon') | sum(start=[]) %}
    {% set x_origin = (all_points | map(attribute=0) | min | default(x_default)) %}
    {% set y_origin = (all_points | map(attribute=1) | min | default(y_default)) %}
    {% set x_origin = ([x_origin, 0] | max) %}
    {% set y_origin = ([y_origin, 0] | max) %}
{% else %}
    {% set x_origin = x_default | float %}
    {% set y_origin = y_default | float %}
{% endif %}
{% set nozzle_dia = printer.configfile.config.extruder.nozzle_diameter | float %}
{% set cross_section = nozzle_dia * z_height | float %}
{% set purge_move_speed = (cross_section * flow_rate) * 60 | float %}
{% set travel_speed = (printer.toolhead.max_velocity) * 60 | float %}

# Garantir que a posição de purga em Y não é negativa
{% set y_purge_position = ([y_origin - distance_to_object_y, 0] | max)+ 3 %} #>>>>>>>>>>avoid go to negative positions + y 3mm <<<<<<<
