description: A purge macro that adapts to be near your actual printed objects
variable_adaptive_enable: True # Change to False if you'd like the purge to be in the same spot every print
variable_z_height: 10 # Height above the bed to purge
variable_purge_amount: 40 # Amount of filament in millimeters to purge
variable_line_length: 50 # Overall desired length of purge line in millimeters, around 1/5th of X axis length is a good starting value
variable_flow_rate: 35 # Desired flow rate in mm3/s (Around 12 for standard flow hotends, around 24 for high flow hotends)
variable_x_default: 115 # Default X location to purge. If adaptive_enable is True, this is overwritten
variable_y_default: 251 # Default Y location to purge. If adaptive_enable is True, this is overwritten
variable_distance_to_object_y: 10 # Y distance in millimeters away from the print area for purging. Must be less than or equal to y_default if adaptive_enable is False
### This section is for those who are using Moonraker's Update Manager for KAMP, or want a more verbose macro. ###
variable_display_parameters: True # Display macro paramters in the console, useful for debugging the SETUP_LINE_PURGE call, or more verbosity.
