# Filament Change
######################################################################

# 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]
