# Goal: Happy Hare supporting MACRO configuration
#
# (\_/)
# ( *,*)
# (")_(") Happy Hare Ready
#
#
# Supporting set of macros supplied with Happy Hare can be customized by editing the macro "variables" declared here.
#
# This configuration will automatically retained and upgraded between releases (a backup of previous config files will
# always be made for your reference). If you want to customize macros beyond what is possible through these variables
# it is highly recommended you copy the macro to a new name and change the callback macro name in 'mmu_parameters.cfg'
# That way the default macros can still be upgraded but your customization will be left intact
#
# PERSISTED STATE ---------------------------------------------------------
# Happy Hare stores configuration and state in the klipper variables file.
# Since klipper can only be a single 'save_variables' file, if you already
# have one you will need to merge the two and point this appropriately.

# Parking and movement controls:
# Happy Hare defines 7 operations that may require parking. You can specify
# whether to park for each of those operations both during a print and
# standalone (not printing) with Happy Hare or when HH is disabled:
#
# enable_park_printing
# This is a list of the operations that should result in toolhead parking
# while in a print. There are really two main starting points from which
# you can customize. If using the slicer to form tips (and toolchange is
# over the wipetower) you don't want to park on "toolchange" but you would
# want to on "runout" which is a forced toolchange unknown by the slicer.
# Typically you would also want to park at least on pause, cancel and
# complete if not done elsewhere
#
# enabled_park_standalone
# List of the operations that should result in toolhead parking when not
# printing, for example, just manipulating the MMU manually or via
# Klipperscreen. Really it is up to you to choose based on personal
# workflow preferences but this defaults to just 'pause,cancel'
# (i.e. disabled for toolchange)
#
# enabled_park_disabled
# List of the operations that should result in toolhead parking when MMU is
# disabled (MMU ENABLE=0) and using Happy Hare client macros. Note that only
# pause and cancel can occur in this mode and would typically be enabled
#
# The operations are as follows:
# toolchange - normal toolchange initiated with Tx or MMU_CHANGE_TOOL command
# runout - when a forced toolchange occurs as a result of runout
# load - individual MMU_LOAD operation
# unload - individual MMU_UNLOAD/MMU_EJECT operation
# complete - when print is complete (Happy Hare enabled)
# pause - a regular klipper PAUSE
# cancel - a regular klipper CANCEL_PRINT
#
# It is possible to call the parking macro manually in this form should you wish
# to include in your macros.
#
# _MMU_PARK FORCE_PARK=1 X=10 Y=10 Z_HOP=5
#
# restore_xy_pos
# Controls where the toolhead (x,y) is returned to after an operation that
# invokes a parking move:
# last - return to original position before park (frequently the default)
# next - return to next print position if possible else last logic will be applied.
# In print this reduces dwell time at the last position reducing blobbing
# and unnecessary movement. Only applied to "toolchange" operation
# none - the toolhead is left wherever it ends up after change. In a print the
# next gcode command will restore toolhead x,y position
#
# Notes:
# - The starting z-height will always be restored, thus the different between 'next'
# and 'none' is the z-height at which the (x,y) move occurs and the location of
# of any un-retract
# - The default parking logic is a straight line move to the 'park_*' position.
# To implement fancy movement and control you can specify your own
# 'user_park_move_macro' to use instead of default straight line move
#
# Retraction can be used to optimize stringing and blobs that can occur when
# changing tools and are active only during a print.
# IMPORTANT: For toolchanging the config order would be:
# 1. In mmu_parameters.cfg configure extruder dimensions like
# 'toolhead_extruder_to_nozzle',etc. These are based on geometry.
# 2. In mmu_parameters.cfg tweak 'toolhead_ooze_reduction' only if necessary
# so that filament _just_ appears at the nozzle on load
# 3. Only then, adjust retraction to control stringing and blobs when
# changing tool in a print

variable_toolchange_fan_speed : 50 ; Fan speed % if using fan_assist enabled
# Step 2 - Nozzle Separation
# The filament is then quickly separated from the meltzone by a fast movement

variable_unloading_speed_start : 80 ; Speed in mm/s for initial fast movement
variable_unloading_speed : 18 ; Speed in mm/s for slow move to cooling zone
# Step 3 - Cooling Moves
# The cooling move allows the filament to harden while constantly moving back
# and forth in the cooling tube portion of the extruder to prevent a bulbous
# tip forming. The cooling tube position is measured from the internal nozzle
# to just past the top of the heater block (often it is beneficial to add a
# couple of mm to ensure the tip is in the cooling section. The cooling tube

# material like PLA to burn off persistent very fine hairs. To work the
# depth of insertion is critical (start with it disabled and tune last)
# For reference the internal nozzle would be at a distance of

variable_cooling_zone_pause : 0 ; Pause if cooling zone after dip in ms. Default 0
