# Servo configuration -----------------------------------------------------------------------------------------------------
servo_up_angle: {servo_up_angle} # Default: MG90S servo: Up=30 ; SAVOX SH0255MG: Up=140
servo_down_angle: {servo_down_angle} # Default: MG90S servo: Down=140 ; SAVOX SH0255MG: Down=30
# Gear stepper load/unload speeds ------------------------------------------------------------------------------------------
# Long moves are faster than the small ones and used for the bulk of the bowden movement
# 100mm/s should be "quiet" with the NEMA14 motor or a NEMA17 pancake, but you can go lower for really low noise
long_moves_speed: 150 # mm/s. Conservative value is 100mm/s, Max around 300mm/s
short_moves_speed: 50 # mm/s. Conservative value is 35mm/s. Max around 100mm/s
# Logging ------------------------------------------------------------------------------------------------------------------
# log_level & logfile_level can be set to one of (0 = essential, 1 = info, 2 = debug, 3 = trace, 4 = developer)
# Generally you can keep console logging to a minimal whilst still sending debug output to the ercf.log file
# Increasing the console log level is only really useful during initial setup to save having to constantly open the log file
log_level: 1
logfile_level: 3 # Can also be set to -1 to disable log file completely
log_statistics: 1 # 1 to log statistics on every toolchange, 0 to disable (but still recorded)
log_visual: 1 # 1 log visual representation of filament, 2 shortened KlipperScreen friendly, 0 disable
startup_status: 0 # Whether to log tool to gate status on startup, 1 = summary, 2 = full, 0 = disable
# Bowden tube movement -----------------------------------------------------------------------------------------------------
# Base value for the loading length used by the auto-calibration macro. Please use a value SMALLER than the real reverse
# bowden length (by about 30-40mm). This is ONLY used during calibration, and has no impact on normal running after calibration
calibration_bowden_length: {calibration_bowden_length}
#
# If you are getting "timer too close" errors, increase the number of moves used during long loading and unloading moves
num_moves: 1 # Number of moves to make when loading or unloading bowden
#
# If enabled, the driver will "believe" the encoder reading and make correction moves to bring the filament to the desired
# end of bowden position. This is useful is you suspect slippage on high speed loading (but requires accurate encoder)
# If disabled, the gear stepper will be solely responsible for filament positioning in bowden (requires minimal friction)
apply_bowden_correction: 0
# Filament homing, loading and unloading controls -------------------------------------------------------------------------
# If you have a toolhead sensor for filament homing:
toolhead_homing_max: 35 # Maximum distance to advance in order to attempt to home to toolhead sensor (default 20)
toolhead_homing_step: 1.0 # Step size to use when homing to the toolhead sensor (default 1)
#
# Options without toolhead sensor (but still needed for calibration with toolhead sensor)
extruder_homing_max: 50 # Maximum distance to advance in order to attempt to home the extruder
extruder_homing_step: 2.0 # Step size to use when homing to the extruder with collision detection (default 2)
#
# For accurate homing and to avoid grinding, tune the gear stepper current reduction (currently TMC2209 only)
# To ensure no skipping during fast tip-forming moves, tune the extruder current increase (currently TMC2209 only)
extruder_homing_current: 40 # Percentage of gear_stepper current (20%-100%) to use when homing to extruder homing (100 to disable)
extruder_form_tip_current: 100 # Percentage of extruder current (100%-150%) to use when forming tip (100 to disable)
#
# How far (mm) to run gear_stepper and extruder together in sync on load and unload. This will make loading and unloading
# more reliable and will act as a "hair pulling" step on unload. These settings are optional - use 0 to disable
# Non zero value for 'sync_load_length' will synchronize the whole homing distance if toolhead sensor is installed
sync_load_length: 10 # mm of synchronized extruder loading at entry to extruder
sync_unload_length: 10 # mm of synchronized movement at start of bowden unloading
#
# This is the distance of the final filament load from the homing point to the nozzle
# If homing to toolhead sensor this will be the distance from the toolhead sensor to the nozzle
# If extruder homing it will be the distance from the extruder gears (end of bowden) to the nozzle
#
# This value can be determined by manually inserting filament to your homing point (extruder gears or toolhead sensor)
# and advancing it 1-2mm at a time until it starts to extrude from the nozzle. Subtract 1-2mm from that distance distance
# to get this value. If you have large gaps in your purge tower, increase this value. If you have blobs, reduce this value.
# This value will depend on your extruder, hotend and nozzle setup.
home_position_to_nozzle: 72 # E.g. Revo Voron with CW2 extruder using extruder homing (62 with toolhead sensor)
#
# Advanced and optional. If you regularly switch between sensorless and toolhead sensor or you want to optimize extruder
# unload when using toolhead sensor you can override 'home_position_to_nozzle' with these more specific values
# (Note that the difference between these two represents the extruder to sensor distance and is used as the final
# unload distance from extruder. An accurate setting can reduce tip noise/grinding on exit from extruder)
#extruder_to_nozzle: 72 # E.g. Revo Voron with CW2 extruder using extruder homing
#sensor_to_nozzle: 62 # E.g. Revo Voron with CW2 extruder using toolhead sensor homing
# Selector gate positions -------------------------------------------------------------------------------------------------
# The position of each gate (tool) on the selector. See the manual for setting these values
colorselector: 2.3, 23.3, 44.3, 70.4, 91.4, 112.4, 138.5, 159.5, 180.5
#
# Optional position of the filament bypass (special version of separator block). Comment out or set to 0 to disable
#bypass_selector: 122.8 # Set to your measured position
# This group of settings collectively form the default gate map which can be updated with the `ERCF_SET_GATE_MAP` command
# or similar commands that determine gate status. They must all be the same length at the number of gates (0 .. n)
# Note that these are the defaults and will be overriden by saved values in ercf_vars.cfg.
#
#
# Whether gate has filament available (1=available, 0=empty). If not specified or commented out all gates are unknown (but available)
#gate_status: 1, 1, 1, 1, 1, 1, 1, 1, 1
#
# Similarly this specifies the material type present in the gate. If not specified for commented out the name will be empty
#gate_material: PLA, ABS+, ABS, ABS, PLA, PLA, PETG, ABS, ABS
#
# Similarly this specifies the color of the filament in each gate. If not specified for commented out the color will be default
#gate_color: red, orange, yellow, green, blue, indigo, violet, ffffff, black
# The default mapping for tool to gate. If not specified or commented out the mapping will default to Tx = Gate #x
# This must be the same length at the number of gates.
# Note that this will be overriden by a saved value in ercf_vars.cfg. ERCF_RESET_TTG_MAP will revert to these default values
tool_to_gate_map: 0, 1, 2, 3, 4, 5, 6, 7, 8
# Options and Features ----------------------------------------------------------------------------------------------------
# Selector operation. If configured for sensorless homing ERCF can detect blocked filament path and try to recover automatically
# Sensorless still requires the physical endstop switch to be configured as the endstop on the (non intuiative) GEAR stepper
sensorless_selector: {sensorless_selector} # 0 = use only a physical endstop, 1 = use advanced sensorless selector homing
enable_clog_detection: {clog_detection} # 0 = disable, 1 = static length clog detection, 2 = automatic length clog detection
enable_endless_spool: {endless_spool} # 0 = disable endless spool, 1 = enable endless spool (requires clog detection)
# If endless spool is turned on, you should define a list of EndlessSpool groups here, one entry for each gate in your ERCF
# when filament runs out on a gate, it will switch to the next gate with the same group number
# for example, if set to 1, 2, 3, 1, 2, 3, 1, 2, 3 on a 9 cart ERCF, and a runout occurs on gate #0
# the ERCF will switch to using gate #3 and then gate #6 automatically remapping the tool as it goes.
# Note that this will be overriden by a saved value in ercf_vars.cfg if modified with ERCF_ENDLESS_SPOOL_GROUPS command
#endless_spool_groups: 1, 2, 3, 1, 2, 3, 1, 2, 3
# Advanced: ERCF can auto-initialize based on previous persisted state. There are 5 levels with each level bringing in
# additional state information requiring progressively less inital setup. The higher level assume that you don't touch
# ERCF while it is offline and it can come back to life exactly where it left off! If you do touch it or get confused
# then issue an appropriate reset command (E.g. ERCF_RESET) to get state back to the defaults.
# Enabling `startup_status` is recommended if you use persisted state at level 2 and above
# Levels: 0 = start fresh every time (the former default behavior)
# 1 = restore persisted endless spool groups
# 2 = additionally restore persisted tool-to-gate mapping
# 3 = additionally restore persisted gate status (filament availability and color)
# 4 = additionally restore persisted tool, gate and filament position!
