Gcode macros to change strip led colors while extruder (and bed) reach temperatures

Macros
1

Finally I have my GCODE to: set (in START_PRINT) the extruder and BED temperature and WAIT for them, and while waiting, I can change neopixels strip led colors…

[gcode_macro START_PRINT]
###come usare con cura per esempio: start_print B={material_bed_temperature_layer_0} H={material_print_temperature_layer_0} L={layer_height} S={speed_travel}
default_parameter_B=70
default_parameter_H=230
default_parameter_L=0.2
default_parameter_S=100

  {% endif %}

[gcode_macro check_temp_1]
gcode:
  {% set wipe_count = 1000 %} #1000 seconds, but if extruder temp is ok, in a 1 seconds it reach the 1000 value !!!
  {% for wipe in range(wipe_count) %}
