######################################################################

# M600: Filament Change. This macro will pause the printer, move the
# tool to the change position, and retract the filament 50mm. Adjust
# the retraction settings for your own extruder. After filament has
# been changed, the print can be resumed from its previous position
# with the "RESUME" gcode.

# Pressure Advance test macro by drawing 20 simple lines
#
# Adapted from: https://www.reddit.com/r/VORONDesign/comments/sjdiol/pressure_advance_testing_macro_klipper/
# to suit home-made free ABL that requires a pause after homing to manually retract the probe.
#
# To do that, the process is divided into 2 macros:
#
# - PA_INIT to bring bed and extruder up to temperature, then home.
#   eg. PA_INIT BED_TEMP=65 EXTRUDER_TEMP=205
#   After homing, the ABL can be manually retracted
#
# - PA_CAL to start the Pressure Advance test.
#   eg. PA_CAL PA_START=0.01 PA_STEP=0.01 NZL=0.4
#   This will draw 20 lines using different PA values
# 
# To use, simply include in printer.cfg:
#
#   [include pa_macro.cfg]

# [gcode_macro PA_INIT]
# gcode:
#   {% set BED_TEMP = params.BED_TEMP|default(60)|float %}
#   {% set EXTRUDER_TEMP = params.EXTRUDER_TEMP|default(190)|float %}
#   M140 S{BED_TEMP} ;Start heating bed
#   M190 S{BED_TEMP} ;Wait for bed to reach temp before proceeding
#   M104 S{EXTRUDER_TEMP} ;Start heating extruder
#   M109 S{EXTRUDER_TEMP} ;Wait for extruder to reach temp before proceeding
#   G28 ;Home all axes and pause with audio alert
