# Include servo hardware definition separately to allow for automatic upgrade
[include blobifier_hw.cfg]
##########################################################################################
# Sample config to be used in conjunction with Blobifier Purge Tray, Bucket & Nozzle
# Scrubber mod. Created by Dendrowen (dendrowen on Discord). The Macro is based on a
# version, and Nozzle Scrubber is made by Hernsl (hernsl#8860 on Discord). The device is
# designed around a Voron V2.4 300mm, but should work for 250mm and 350mm too. This
# version only supports the assembly on the rear-left of the bed. If you decide to change
# that, please consider contributing to the project by creating a pull request with the
# needed changes.
# IMPORTANT: The rear-left part of your bed becomes unusable by this mod because the
# toolhead needs to lower down to 0. Be sure not to use the left-rear 130x35mm.
# The goals of this combination of devices is to dispose of purged filament during a
# multicolored print without the need of a purge block and without the flurries of
# filament poops consuming your entire 3D printer room. The Blobifier achieves that by
# purging onto a retractable tray which causes the filament to turn into a tiny blob
# rather then a large spiral. This keeps the waste relatively small. The bucket should be
# able to account for up to 200 filament swaps (for the 300mm V2).
# The Blobifier uses some room at the back-left side of your printer, depending on your
# printer limits and positions. (usually max_pos.y - toolhead_y and brush_start +
# brush_width + toolhead_x). If you do place objects within this region, Blobifier will
# skip purging automatically. It does this by extending the EXCLUDE_OBJECT_* macro's, so
# make sure you have exclude objects enabled in your slicer.
# If your using Blobifier in conjunction with the filament cutter on the stealthburner
# toolhead, you can place the pin at max_pos.y - 7 (e.g., max pos y is 307, place it at
# 300). The pin will then poke through the cavity in your toolhead. (Be careful with
# manually moving the toolhead. I have broken many filament cutter pins)
# It is advised to use the start_gcode from Happy Hare. Then you will be able to fully
# and efficiently use this mod. Check the Happy Hare document at gcode_preprocessing.md
# in the Happy Hare github for more details.

variable_brush_accel: 0
# Blobifier sends the toolhead to the maximum y position during purge operations and

#
# Goal: Happy Hare MMU hardware config file with config for MMB11 MCU board
#
# (\_/)
# ( *,*)
# (")_(") Happy Hare Ready
#
#
# Notes about setup of common external MCUs can be found here:
# https://github.com/moggieuk/Happy-Hare/blob/main/doc/mcu_notes.md
#
# Note about "touch" endstops: Happy Hare provides extremely flexible homing options using both single steppers or
# synced steppers. The "touch" option leverages stallguard and thus requires the appropriate 'diag_pin' and stallguard
# parameters set on the TMC driver section. If you have the diag_pin exposed, it is harmless to define this because
# they will only be used when explicitly needed and configured.
#
# Touch option for each stepper provides these benefits / possibilities (experimental):
# - on extruder stepper allows for the automatic detection of the nozzle!
# - on selector stepper allows for the automatic detection of filament stuck in the gate and subsequent recovery
# - on gear stepper allows for the automatic detection of the extruder entrance
#
# These sound wonderful right? They are, but there are caveats:
# - Some external MCUs are terrible at detecting stallguard and often result in an "undervoltage error"
# It is generally possible to get selector touch (TMC2209) tuned especially if you set 'stealthchop_threshold'
# to a value greater than homing speeds and less than move speed. I.e. the stepper runs in stealthchop mode when
# homing. [klipper experts will know that it switches the chip mode automatically to stealthchop and then back for
# Stallguard2 support, however the automatic switching back to spreadcycle at the end homing move seems to provoke
# the error condition and setting 'stealthchop_threshold' appropriately avoids this condition. More than you wanted
# to know I'm sure!
# - I have not had much luck with touch (stallguard) on the gear stepper with EASY-BRD and ERB MCUs and you really
# want the extra torque of spreadcycle so adjusting 'stealthchop_threshold' is not really an option
# - Enabling on the extruder stepper is viable but you will likely have to change jumpers on your main mcu to expose
# the DIAG pin for whichever driver the extruder stepper is connected to.
#
# In summary, "touch" homing with your MMU is an advanced option that requires patience and careful tuning. Everything
# works with regular endstops and there are workaround options for certain homing points (like extruder entry) in
# the absence of any endstop. I'm really interested in creative setups. Ping me on Discord (moggieuk#6538)
#
# See 'mmu.cfg' for serial definition and pins aliases
#
# HOMING CAPABLE EXTRUDER (VERY ADVANCED) -----------------------------------------------------------------------------
# With Happy Hare installed even the extruder can be homed. You will find the usual 'endstop' parameters can be added
# to your '[extruder]' section. Useless you have some clever load cell attached to your nozzle it only really makes
# sense to configure stallguard style "touch" homing. To do this add lines similar to this to your existing
# '[extruder]' definition in printer.cfg.
#
# [extruder]
# endstop_pin: tmc2209_extruder:virtual_endstop
#
# Also be sure to add the appropriate stallguard config to the TMC section, e.g.
#
# [tmc2209 extruder]
# diag_pin: E_DIAG # Set to MCU pin connected to TMC DIAG pin for extruder
# driver_SGTHRS: 100 # 255 is most sensitive value, 0 is least sensitive
#
# Happy Hare will take care of the rest and add a 'mmu_ext_touch' endstop automatically

chain_count: 9 # Need number gates x1 or x2 + status leds
color_order: GRBW # Set based on your particular neopixel specification (can be comma separated list)
# MMU LED EFFECT SEGMENTS ----------------------------------------------------------------------------------------------
# Define neopixel LEDs for your MMU. The chain_count must be large enough for your desired ranges:
# exit .. this set of LEDs, one for every gate, usually would be mounted at the exit point of the gate
# entry .. this set of LEDs, one for every gate, could be mounted at the entry point of filament into the MMU/buffer
# status .. these LED. represents the status of the MMU (and selected filament). More than one status LED is possible
# logo .. these LEDs don't change during operation and are designed for driving a logo. More than one logo LED is possible
#
# Note that all sets are optional. You can opt to just have the 'exit' set for example. The advantage to having
# both entry and exit LEDs is, for example, so that 'entry' can display gate status while 'exit' displays the color
#
# The animation effects requires the installation of Julian Schill's awesome LED effect module otherwise the LEDs
# will be static:
# https://github.com/julianschill/klipper-led_effect
#
# LED's are indexed in the chain from 1..N. Thus to set up LED's on 'exit' and a single 'status' LED on a 4 gate MMU:
#
# exit_leds: neopixel:mmu_leds (1,2,3,4)
# status_leds: neopixel:mmu_leds (5)
#
# In this example no 'entry' set is configured. Note that constructs like "mmu_leds (1-3,4)" are also valid
#
# The range is completely flexible and can be comprised of different led strips, individual LEDs, or combinations of
# both on different pins. In addition, the ordering is flexible based on your wiring, thus (1-4) and (4-1) both represent
# the same LED range but mapped to increasing or decreasing gates respectively. E.g if you have two Box Turtle MMUs, one
# with a chain of LEDs wired in reverse order and another with individual LEDs, to define 8 exit LEDs:
#
# exit_leds: neopixel:bt_1 (4-1)
# neopixel:bt_2a
# neopixel:bt_2b
# neopixel:bt_2c
# neopixel:bt_2d
#
# Note the use of separate lines for each part of the definition,
#
# ADVANCED: Happy Hare provides a convenience wrapper [mmu_led_effect] that not only creates an effect on each of the
# [mmu_leds] specified segments as a whole but also each individual LED for atomic control. See mmu_leds.cfg for examples
#
# (comment out this whole section if you don't have/want leds; uncomment/edit LEDs fitted on your MMU)

# 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
# - x,y parking coordinates can be negative if your printer can handle it
#
# 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

# Step 2 - Nozzle Separation
# The filament is then quickly separated from the meltzone by a fast movement
# before then slowing to travel the remaining distance to cooling tube. The
# initial fast movement should be as fast as extruder can comfortably perform.
# A good starting point# for slower move is unloading_speed_start/cooling_moves.
# Too fast a slower movement can lead to excessively long tips or hairs
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
# length is then the distance from here to top of heatsink (this is the length
# length of the cooling moves). The final cooling move is a fast movement to
# break the string formed.

# Step 4 - Skinnydip
# Skinnydip is an advanced final move that may have benefit with some
# 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

# Happy Hare needs a reference "homing point" close to the extruder from which to accurately complete the loading of
# the toolhead. This homing operation takes place after the fast bowden load and it is anticipated that that load
# operation will leave the filament just shy of the homing point. If using a toolhead sensor this initial extruder
# homing is unnecessary (but can be forced) because the homing will occur inside the extruder for the optimum in accuracy.
# You still should set this homing method because it is also used for the determination and calibration of bowden length.
#
# In addition to an entry sensor "extruder" it is possible for Happy Hare to "feel" for the extruder gear entry
# by colliding with it. This can be done with encoder based collision detection, the compression of the sync-feedback
# (aka buffer) sensor or using "touch" (stallguard) on the gear stepper. Note that encoder collision detection is not
# completely deterministic and you will have to find the sweetspot for your setup by adjusting the TMC current reduction.
# Note that reduced current during collision detection can also prevent unecessary filament griding.
#
# Possible extruder_homing_endtop names:
# collision - Detect the collision with the extruder gear by monitoring encoder movement (Requires encoder)
# Fast bowden load will move to the extruder gears
# mmu_gear_touch - Use touch detection when the gear stepper hits the extruder (Requires stallguard)
# Fast bowden load will move to extruder_homing_buffer distance before extruder gear, then home
# extruder - If you have a "filament entry" endstop configured (Requires 'extruder' endstop)
# Fast bowden load will move to extruder_homing_buffer distance before sensor, then home
# filament_compression - If you have a "sync-feedback" sensor with compression switch configured
# Fast bowden load will move to extruder_homing_buffer distance before extruder gear, then home
# none - Don't attempt to home. Only possibiliy if lacking all sensor options
# Fast bowden load will move to the extruder gears. Option is fine if using toolhead sensor

# It is possible to define highly customized loading and unloading sequences, however, unless you have a specialized
# setup it is probably easier to opt for the built-in toolhead loading and unloading sequence which already offers a
# high degree of customization. If you need even more control then edit the _MMU_LOAD_SEQUENCE and _MMU_UNLOAD_SEQUENCE
# macros in mmu_sequence.cfg - but be careful!
#
# An MMU must have a known point at the end of the bowden from which it can precisely load the extruder. Generally this
# will either be the extruder entrance (which is controlled with settings above) or by homing to toolhead sensor. If
# you have toolhead sensor it is past the extruder gear and the driver needs to know the max distance (from end of
# bowden move) to attempt homing
#
toolhead_homing_max: 40 # Maximum distance to advance in order to attempt to home to defined homing endstop
# IMPORTANT: These next three settings are based on the physical dimensions of your toolhead
# Once a homing position is determined, Happy Hare needs to know the final move distance to the nozzle. There is only
# one correct value for your setup - use 'toolhead_ooze_reduction' (which corresponds to the residual filament left in
# your nozzle) to control excessive oozing on load. See doc for table of proposed values for common configurations.
#
# NOTE: If you have a toolhead sensor you can automate the calculation of these parameters! Read about the
# `MMU_CALIBRATE_TOOLHEAD` command (https://github.com/moggieuk/Happy-Hare/wiki/Blobbing-and-Stringing#---calibrating-toolhead)
#
toolhead_extruder_to_nozzle: 72 # Distance from extruder gears (entrance) to nozzle
toolhead_sensor_to_nozzle: 62 # Distance from toolhead sensor to nozzle (ignored if not fitted)
toolhead_entry_to_extruder: 8 # Distance from extruder "entry" sensor to extruder gears (ignored if not fitted)
# This setting represents how much residual filament is left behind in the nozzle when filament is removed, it is thus
# used to reduce the extruder loading length and prevent excessive blobbing but also in the calculation of purge volume.
# Note that this value can also be measured with the `MMU_CALIBRATE_TOOLHEAD` procedure
#
toolhead_residual_filament: 0 # Reduction in extruder loading length because of residual filament left behind
# TUNING: Finally, this is the last resort tuning value to fix blobbing. It is expected that this value is NEAR ZERO as
# it represents a further reduction in extruder load length to fix blobbing. If using a wipetower and you experience blobs
# on it, increase this value (reduce the quantity of filament loaded). If you experience gaps, decrease this value. If gaps
# and already at 0 then perhaps the 'toolhead_extruder_to_nozzle' or 'toolhead_residual_filament' settings are incorrect.
# Similarly a value >+5mm also suggests the four settings above are not correct. Also see 'retract' setting in
# 'mmu_macro_vars.cfg' for final in-print ooze tuning.
#
toolhead_ooze_reduction: 0 # Reduction in extruder loading length to prevent ooze (represents filament remaining)
# Distance added to the extruder unload movement to ensure filament is free of extruder. This adds some degree of tolerance
# to slightly incorrect configuration or extruder slippage. However don't use as an excuse for incorrect toolhead settings
#
toolhead_unload_safety_margin: 10 # Extra movement safety margin (default: 10mm)
# If not synchronizing gear and extruder and you experience a "false" clog detection immediately after the tool change
# it might be because of a long bowden and/or large internal diameter that causes slack in the filament. This optional
# move will tighten the filament after a load by % of current clog detection length. Gear stepper will run at 50% current
#
toolhead_post_load_tighten: 60 # % of clog detection length, 0 to disable. Ignored if 'sync_to_extruder: 1'
# ADVANCED: Controls the detection of successful extruder load/unload movement and represents the fraction of allowable
# mismatch between actual movement and that seen by encoder. Setting to 100% tolerance effectively turns off checking.
# Some designs of extruder have a short move distance that may not be picked up by encoder and cause false errors. This
# allows masking of those errors. However the error often indicates that your extruder load speed is too high or the
# friction is too high on the filament and in that case masking the error is not a good idea. Try reducing friction
# and lowering speed first!

#

#
# Often it is useful to increase the extruder current for the rapid movement to ensure high torque and no skipped steps

# If your MMU has a dc motor (often N20) controlled respooler/assist then how it operates can be controlled with these
# settings. Typically the espooler will be controlled with PWM signal. This will be at the maximum at speeds equal or
# above 'espooler.max_stepper_speed'. The PWM signal will scale downwards towards 0 for slower speeds. The falloff being
