## Customization:
##   1) copy the gcode_macro _CLIENT_VARIABLE (see below) to your printer.cfg
##   2) remove the comment mark (#) from all lines
##   3) change any value in there to your needs
##
## Use the PAUSE macro direct in your M600:
##  e.g. with a different park position front left and a minimal height of 50
##    [gcode_macro M600]
##    description: Filament change
##    gcode: PAUSE X=10 Y=10 Z_MIN=50
##  Z_MIN will park the toolhead at a minimum of 50 mm above to bed to make it easier for you to swap filament.
##
## Client variable macro for your printer.cfg
#[gcode_macro _CLIENT_VARIABLE]
#variable_use_custom_pos   : False ; use custom park coordinates for x,y [True/False]
#variable_custom_park_x    : 0.0   ; custom x position; value must be within your defined min and max of X
#variable_custom_park_y    : 0.0   ; custom y position; value must be within your defined min and max of Y
#variable_custom_park_dz   : 2.0   ; custom dz value; the value in mm to lift the nozzle when move to park position
#variable_retract          : 1.0   ; the value to retract while PAUSE
#variable_cancel_retract   : 5.0   ; the value to retract while CANCEL_PRINT
#variable_speed_retract    : 35.0  ; retract speed in mm/s
#variable_unretract        : 1.0   ; the value to unretract while RESUME
#variable_speed_unretract  : 35.0  ; unretract speed in mm/s
#variable_speed_hop        : 15.0  ; z move speed in mm/s
#variable_speed_move       : 100.0 ; move speed in mm/s
#variable_park_at_cancel   : False ; allow to move the toolhead to park while execute CANCEL_PRINT [True/False]
#variable_park_at_cancel_x : None  ; different park position during CANCEL_PRINT [None/Position as Float]; park_at_cancel must be True
#variable_park_at_cancel_y : None  ; different park position during CANCEL_PRINT [None/Position as Float]; park_at_cancel must be True
## !!! Caution [firmware_retraction] must be defined in the printer.cfg if you set use_fw_retract: True !!!
#variable_use_fw_retract   : False ; use fw_retraction instead of the manual version [True/False]
#variable_idle_timeout     : 0     ; time in sec until idle_timeout kicks in. Value 0 means that no value will be set or restored
