variable_use_custom_pos   : True ; use custom park coordinates for x,y [True/False]
variable_custom_park_x    : 5.0   ; custom x position; value must be within your defined min and max of X
variable_custom_park_y    : 320.0   ; custom y position; value must be within your defined min and max of Y
variable_custom_park_dz   : 10.0   ; custom dz value; the value in mm to lift the nozzle when move to park position
variable_retract          : .60   ; 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        : .70   ; 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   : True ; 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
variable_runout_sensor    : "filament_switch_sensor filament_sensor"    ; If a sensor is defined, it will be used to cancel the execution of RESUME in case no filament is detected.
#                                   Specify the config name of the runout sensor e.g "filament_switch_sensor runout". Hint use the same as in your printer.cfg
# !!! Custom macros, please use with care and review the section of the corresponding macro.
## These macros are for simple operations like setting a status LED. Please make sure your macro does not interfere with the basic macro functions.
## Only  single line commands are supported, please create a macro if you need more than one command.
