# This file serves as documentation for config parameters of
# additional devices that may be configured on a printer. The snippets
# in this file may be copied into the main printer.cfg file. See the
# "example.cfg" file for description of common config parameters.
#
# Note, where an extra config section creates additional pins, the
# section defining the pins must be listed in the config file before
# any sections using those pins.


# Z height probe. One may define this section to enable Z height
# probing hardware. When this section is enabled, PROBE and
# QUERY_PROBE extended g-code commands become available. The probe
# section also creates a virtual "probe:z_virtual_endstop" pin. One
# may set the stepper_z endstop_pin to this virtual pin on cartesian
# style printers that use the probe in place of a z endstop. If using
# "probe:z_virtual_endstop" then do not define a position_endstop in
# the stepper_z config section.
#[probe]
#pin: ar15
#   Probe detection pin. This parameter must be provided.
#x_offset: 0.0
#   The distance (in mm) between the probe and the nozzle along the
#   x-axis. The default is 0.
#y_offset: 0.0
#   The distance (in mm) between the probe and the nozzle along the
#   y-axis. The default is 0.
#z_offset:
#   The distance (in mm) between the bed and the nozzle when the probe
#   triggers. This parameter must be provided.
#speed: 5.0
#   Speed (in mm/s) of the Z axis when probing. The default is 5mm/s.
#samples: 1
#   The number of times to probe each point. The probed z-values will
#   be averaged. The default is to probe 1 time.
#sample_retract_dist: 2.0
#   The distance (in mm) to lift the toolhead between each sample (if
#   sampling more than once). The default is 2mm.
#samples_result: average
#   The calculation method when sampling more than once - either
#   "median" or "average". The default is average.
#samples_tolerance: 0.100
#   The maximum Z distance (in mm) that a sample may differ from other
#   samples. If this tolerance is exceeded then either an error is
#   reported or the attempt is restarted (see
#   samples_tolerance_retries). The default is 0.100mm.
#samples_tolerance_retries: 0
#   The number of times to retry if a sample is found that exceeds
#   samples_tolerance. On a retry, all current samples are discarded
#   and the probe attempt is restarted. If a valid set of samples are
#   not obtained in the given number of retries then an error is
#   reported. The default is zero which causes an error to be reported
#   on the first sample that exceeds samples_tolerance.
#activate_gcode:
#   A list of G-Code commands to execute prior to each probe attempt.
#   See docs/Command_Templates.md for G-Code format. This may be
#   useful if the probe needs to be activated in some way. Do not
#   issue any commands here that move the toolhead (eg, G1). The
#   default is to not run any special G-Code commands on activation.
#deactivate_gcode:
#   A list of G-Code commands to execute after each probe attempt
#   completes. See docs/Command_Templates.md for G-Code format. Do not
#   issue any commands here that move the toolhead. The default is to
#   not run any special G-Code commands on deactivation.


# BLTouch probe. One may define this section (instead of a probe
# section) to enable a BLTouch probe. (Note! This bltouch module may
# not work correctly with some BLTouch "clones"!) A virtual
# "probe:z_virtual_endstop" pin is also created (see the "probe"
# section above for the details).
#[bltouch]
#sensor_pin:
#   Pin connected to the BLTouch sensor pin. This parameter must be
#   provided.
#control_pin:
#   Pin connected to the BLTouch control pin. This parameter must be
#   provided.
#pin_move_time: 0.675
#   The amount of time (in seconds) to wait for the BLTouch pin to
#   move up or down. The default is 0.675 seconds.
#pin_up_reports_not_triggered: True
#   Set if the BLTouch consistently reports the probe in a "not
#   triggered" state after a successful "pin_up" command. This should
#   be True for a genuine BLTouch; some BLTouch clones may require
#   False. The default is True.
#pin_up_touch_mode_reports_triggered: True
#   Set if the BLTouch consistently reports a "triggered" state after
#   the commands "pin_up" followed by "touch_mode". This should be
#   True for a genuine BLTouch v2 and earlier; the BLTouch v3 and some
#   BLTouch clones require False. The default is True.
#x_offset:
#y_offset:
#z_offset:
#speed:
#samples:
#sample_retract_dist:
#samples_result:
#   See the "probe" section for information on these parameters.


# Bed tilt compensation. One may define a [bed_tilt] config section to
# enable move transformations that account for a tilted bed.
#[bed_tilt]
#x_adjust: 0
#   The amount to add to each move's Z height for each mm on the X
#   axis. The default is 0.
#y_adjust: 0
#   The amount to add to each move's Z height for each mm on the Y
#   axis. The default is 0.
#z_adjust: 0
#   The amount to add to the Z height when the nozzle is nominally at
#   0,0. The default is 0.
# The remaining parameters control a BED_TILT_CALIBRATE extended
# g-code command that may be used to calibrate appropriate x and y
# adjustment parameters.
#points:
#   A list of X,Y coordinates (one per line; subsequent lines
#   indented) that should be probed during a BED_TILT_CALIBRATE
#   command. Specify coordinates of the nozzle and be sure the probe
#   is above the bed at the given nozzle coordinates. The default is
#   to not enable the command.
#speed: 50
#   The speed (in mm/s) of non-probing moves during the calibration.
#   The default is 50.
#horizontal_move_z: 5
#   The height (in mm) that the head should be commanded to move to
#   just prior to starting a probe operation. The default is 5.


# Mesh Bed Leveling. One may define a [bed_mesh] config section
# to enable move transformations that offset the z axis based
# on a mesh generated from probed points. Note that bed_mesh
# and bed_tilt are incompatible, both cannot be defined.  When
# using a probe to home the z-axis, it is recommended to define
# a [homing_override] section in printer.cfg to home toward the
# center of the print area.
#
#  Visual Examples:
#   rectangular bed, probe_count = 3,3:
#               x---x---x (max_point)
#               |
#               x---x---x
#                       |
#   (min_point) x---x---x
#
#   round bed, round_probe_count = 5, bed_radius = r:
#                  x (0,r) end
#                /
#              x---x---x

#              x---x---x
#                    /
#                  x  (0,-r) start
#
#[bed_mesh]
#speed: 50
#   The speed (in mm/s) of non-probing moves during the
#   calibration. The default is 50.
#horizontal_move_z: 5
#   The height (in mm) that the head should be commanded to move to
#   just prior to starting a probe operation. The default is 5.
#bed_radius:
#   Defines the radius to probe for round beds.  Note that the radius
#   is relative to the nozzle's origin, if using a probe be sure to
#   account for its offset.  This parameter must be provided for round
#   beds and omitted for rectangular beds.
#min_point:
#   Defines the minimum x,y position to probe when for rectangular
#   beds. Note that this refers to the nozzle position, take care that
#   you do not define a point that will move the probe off of the bed.
#   This parameter must be provided for rectangular beds.
#max_point:
#   Defines the maximum x,y position to probe when for rectangular
#   beds. Follow the same precautions as listed in min_point. Also note
#   that this does not necessarily define the last point probed, only
#   the maximum coordinate. This parameter must be provided.
#probe_count: 3,3
#   For rectangular beds, this is a comma separate pair of integer
#   values (X,Y) defining the number of points to probe along each axis.
#   A single value is also valid, in which case that value will be applied
#   to both axes.  Default is 3,3.
#round_probe_count: 5
#   For round beds, this is integer value defines the maximum number of
#   points to probe along each axis. This value must be an odd number.
#   Default is 5.
#fade_start: 1.0
#   The gcode z position in which to start phasing out z-adjustment
#   when fade is enabled.  Default is 1.0.
#fade_end: 0.0
#   The gcode z position in which phasing out completes.  When set
#   to a value below fade_start, fade is disabled. It should be
#   noted that fade may add unwanted scaling along the z-axis of a
#   print.  If a user wishes to enable fade, a value of 10.0 is
#   recommended. Default is 0.0, which disables fade.
#fade_target:
#   The z position in which fade should converge. When this value is set
#   to a non-zero value it must be within the range of z-values in the mesh.
#   Users that wish to converge to the z homing position should set this to 0.
#   Default is the average z value of the mesh.
#split_delta_z: .025
#   The amount of Z difference (in mm) along a move that will
#   trigger a split. Default is .025.
#move_check_distance: 5.0
#   The distance (in mm) along a move to check for split_delta_z.
#   This is also the minimum length that a move can be split. Default
#   is 5.0.
#mesh_pps: 2,2
#   A comma separated pair of integers (X,Y) defining the number of
#   points per segment to interpolate in the mesh along each axis. A
#   "segment" can be defined as the space between each probed
#   point. The user may enter a single value which will be applied
#   to both axes.  Default is 2,2.
#algorithm: lagrange
#   The interpolation algorithm to use. May be either "lagrange"
#   or "bicubic". This option will not affect 3x3 grids, which
#   are forced to use lagrange sampling.  Default is lagrange.
#bicubic_tension: .2
#   When using the bicubic algorithm the tension parameter above
#   may be applied to change the amount of slope interpolated.
#   Larger numbers will increase the amount of slope, which
#   results in more curvature in the mesh. Default is .2.
#relative_reference_index:
#   A point index in the mesh to reference all z values to. Enabling
#   this parameter produces a mesh relative to the probed z position
#   at the provided index.


# Tool to help adjust bed leveling screws. One may define a
# [bed_screws] config section to enable a BED_SCREWS_ADJUST g-code
# command.
#[bed_screws]
#screw1: 100,100
#   The X,Y coordinate of the first bed leveling screw. This is a
#   position to command the nozzle to that is directly above the bed
#   screw (or as close as possible while still being above the bed).
#   This parameter must be provided.
#screw1_name: front screw
#   An arbitrary name for the given screw. This name is displayed when
#   the helper script runs. The default is to use a name based upon
#   the screw XY location.
#screw1_fine_adjust:
#   An X,Y coordinate to command the nozzle to so that one can fine
#   tune the bed leveling screw. The default is to not perform fine

# g-code command.
#[screws_tilt_adjust]
#screw1: 100,100
#   The X,Y coordinate of the first bed leveling screw. This is a
#   position to command the nozzle to that is directly above the bed
#   screw (or as close as possible while still being above the bed).
#   This is the base screw used in calculations.
#   This parameter must be provided.
#screw1_name: front screw
#   An arbitrary name for the given screw. This name is displayed when
#   the helper script runs. The default is to use a name based upon

#   counter-clockwise decrease.
#   Accepted values: CW-M3, CCW-M3, CW-M4, CCW-M4, CW-M5, CCW-M5.
#   Default value is CW-M3, most printers use an M3 screw and
#   turning the knob clockwise decrease distance.

# Multiple Z stepper tilt adjustment. This feature enables independent
# adjustment of multiple z steppers (see stepper_z1 section below) to
# adjust for tilt. If this section is present then a Z_TILT_ADJUST
# extended G-Code command becomes available.
#[z_tilt]
#z_positions:
#   A list of X,Y coordinates (one per line; subsequent lines
#   indented) describing the location of each bed "pivot point". The
#   "pivot point" is the point where the bed attaches to the given Z
#   stepper. It is described using nozzle coordinates (the XY position
#   of the nozzle if it could move directly above the point). The
#   first entry corresponds to stepper_z, the second to stepper_z1,
#   the third to stepper_z2, etc. This parameter must be provided.

#   indented) that should be probed during a Z_TILT_ADJUST command.
#   Specify coordinates of the nozzle and be sure the probe is above
#   the bed at the given nozzle coordinates. This parameter must be

#retry_tolerance: 0
# if retries are enabled then retry if largest and smallest probed points
# differ more than retry_tolerance.
# Note the smallest unit of change here would be a single step. However if you
# are probing more points than steppers then you will likely have a fixed
# minimum value for the range of probed points which you can learn by observing
# command output.


# Moving gantry leveling using 4 independently controlled Z motors.
# Corrects hyperbolic parabola effects (potato chip) on moving gantry
# which is more flexible.
# WARNING: Using this on a moving bed may lead to undesirable results.
# If this section is present then a QUAD_GANTRY_LEVEL extended G-Code
# command becomes available. This routine assumes the following Z motor
# configuration:
# ----------------
# |Z1          Z2|
# |  ---------   |
# |  |       |   |
# |  |       |   |
# |  x--------   |
# |Z           Z3|
# ----------------
# Where x is the (0,0) point on the bed
#[quad_gantry_level]
#gantry_corners:
#   A newline separated list of X,Y coordinates describing the
#   two opposing corners of the gantry. The first entry corresponds to
#   Z, the second to Z2.
#   This parameter must be provided.
#points:
#   A newline separated list of four X,Y points that should be probed
#   during a QUAD_GANTRY_LEVEL command.

#max_adjust: 4
#   Saftey limit if an ajustment greater than this value is requested
#   quad_gantry_level will abort.
#retries: 0
#   number of times to retry if the probed points aren't within tolerance
#retry_tolerance: 0
#   if retries are enabled then retry if largest and smallest probed points
#   differ more than retry_tolerance


# Printer Skew Correction.  It is possible to use software to correct
# printer skew across 3 planes, xy, xz, yz.  This is done by printing
# a calibration model along a plane and measuring three lengths.  Due
# to the nature of skew correction these lengths are set via gcode. See
# skew_correction.md and G-Codes.md in the docs directory for details.
#
#[skew_correction]


# In a multi-extruder printer add an additional extruder section for
# each additional extruder. The additional extruder sections should be
# named "extruder1", "extruder2", "extruder3", and so on. See the
# "extruder" section in example.cfg for a description of available
# parameters.
#[extruder1]
#step_pin: ar36
#dir_pin: ar34
#...
#shared_heater:
#   If this extruder uses the same heater already defined for another
#   extruder then place the name of that extruder here.  For example,
#   should extruder3 and extruder4 share a heater then the extruder3
#   config section should define the heater and the extruder4 section
#   should specify "shared_heater: extruder3". The default is to not
#   reuse an existing heater.
#deactivate_gcode:
#   A list of G-Code commands to execute on a G-Code tool change
#   command (eg, "T1") that deactivates this extruder and activates
#   some other extruder. See docs/Command_Templates.md for G-Code
#   format. It only makes sense to define this section on
#   multi-extruder printers. The default is to not run any special
#   G-Code commands on deactivation.
#activate_gcode:
#   A list of G-Code commands to execute on a G-Code tool change
#   command (eg, "T0") that activates this extruder. See
#   docs/Command_Templates.md for G-Code format. It only makes sense
#   to define this section on multi-extruder printers. The default is
#   to not run any special G-Code commands on activation.


# Support for cartesian printers with dual carriages on a single
# axis. The active carriage is set via the SET_DUAL_CARRIAGE extended
# g-code command. The "SET_DUAL_CARRIAGE CARRIAGE=1" command will
# activate the carriage defined in this section (CARRIAGE=0 will
# return activation to the primary carriage). Dual carriage support is
# typically combined with extra extruders - use the SET_DUAL_CARRIAGE
# command in the activate_gcode / deactivate_gcode section of the
# appropriate extruder. Be sure to also use that mechanism to park the
# carriages during deactivation.
#[dual_carriage]
#axis:
#   The axis this extra carriage is on (either x or y). This parameter
#   must be provided.

# Heater and temperature sensor verification. Heater verification is
# automatically enabled for each heater that is configured on the
# printer. Use verify_heater sections to change the default settings.
#[verify_heater heater_config_name]
#max_error: 120
#   The maximum "cumulative temperature error" before raising an
#   error. Smaller values result in stricter checking and larger
#   values allow for more time before an error is reported.
#   Specifically, the temperature is inspected once a second and if it
#   is close to the target temperature then an internal "error
#   counter" is reset; otherwise, if the temperature is below the
#   target range then the counter is increased by the amount the
#   reported temperature differs from that range. Should the counter
#   exceed this "max_error" then an error is raised. The default is
#   120.
#check_gain_time:
#   This controls heater verification during initial heating.  Smaller
#   values result in stricter checking and larger values allow for
#   more time before an error is reported. Specifically, during
#   initial heating, as long as the heater increases in temperature
#   within this time frame (specified in seconds) then the internal
#   "error counter" is reset. The default is 20 seconds for extruders
#   and 60 seconds for heater_bed.
#hysteresis: 5
#   The maximum temperature difference (in Celsius) to a target
#   temperature that is considered in range of the target. This
#   controls the max_error range check. It is rare to customize this
#   value. The default is 5.
#heating_gain: 2
#   The minimum temperature (in Celsius) that the heater must increase
#   by during the check_gain_time check. It is rare to customize this
#   value. The default is 2.


# Idle timeout. An idle timeout is automatically enabled - add an
# explicit idle_timeout config section to change the default settings.
#[idle_timeout]
#gcode:
#   A list of G-Code commands to execute on an idle timeout. See
#   docs/Command_Templates.md for G-Code format. The default is to run
#   "TURN_OFF_HEATERS" and "M84".
#timeout: 600
#   Idle time (in seconds) to wait before running the above G-Code
#   commands. The default is 600 seconds.


# Multi-stepper axes. On a cartesian style printer, the stepper
# controlling a given axis may have additional config blocks defining
# steppers that should be stepped in concert with the primary
# stepper. One may define any number of sections with a numeric suffix
# starting at 1 (for example, "stepper_z1", "stepper_z2", etc.).
#[stepper_z1]
#step_pin: ar36
#dir_pin: ar34
#enable_pin: !ar30
#step_distance: .005
#   See the example.cfg for the definition of the above parameters.
#endstop_pin: ^ar19
#   If an endstop_pin is defined for the additional stepper then the
#   stepper will home until the endstop is triggered. Otherwise, the
#   stepper will home until the endstop on the primary stepper for the
#   axis is triggered.


# Stepper phase adjusted endstops. To use this feature, define a
# config section with an "endstop_phase" prefix followed by the name
# of the corresponding stepper config section (for example,
# "[endstop_phase stepper_z]"). This feature can improve the accuracy
# of endstop switches. Add a bare "[endstop_phase]" declaration to
# enable the ENDSTOP_PHASE_CALIBRATE command.
#[endstop_phase stepper_z]
#phases:
#   This specifies the number of phases of the given stepper motor
#   driver (which is the number of micro-steps multiplied by four).
#   This setting is automatically determined if one uses a TMC driver
#   with run-time configuration. Otherwise, this parameter must be
#   provided.
#endstop_accuracy: 0.200
#   Sets the expected accuracy (in mm) of the endstop. This represents
#   the maximum error distance the endstop may trigger (eg, if an
#   endstop may occasionally trigger 100um early or up to 100um late
#   then set this to 0.200 for 200um). The default is
#   phases*step_distance.
#endstop_phase:
#   This specifies the phase of the stepper motor driver to expect
#   when hitting the endstop. Only set this value if one is sure the
#   stepper motor driver is reset every time the mcu is reset. If this
#   is not set, then the stepper phase will be detected on the first
#   home and that phase will be used on all subsequent homes.
#endstop_align_zero: False
#   If true then the position_endstop of the axis will effectively be
#   modified so that the zero position for the axis occurs at a full
#   step on the stepper motor. (If used on the Z axis and the print
#   layer height is a multiple of a full step distance then every
#   layer will occur on a full step.) The default is False.


# Heater cooling fans (one may define any number of sections with a
# "heater_fan" prefix). A "heater fan" is a fan that will be enabled
# whenever its associated heater is active. By default, a heater_fan
# has a shutdown_speed equal to max_power.

#heater: extruder
#   Name of the config section defining the heater that this fan is
#   associated with. If a comma separated list of heater names is
#   provided here, then the fan will be enabled when any of the given
#   heaters are enabled. The default is "extruder".
#heater_temp: 50.0
#   A temperature (in Celsius) that the heater must drop below before
#   the fan is disabled. The default is 50 Celsius.
#fan_speed: 1.0
#   The fan speed (expressed as a value from 0.0 to 1.0) that the fan
#   will be set to when its associated heater is enabled. The default
#   is 1.0


# Controller cooling fan (one may define any number of sections with a
# "controller_fan" prefix). A "controller fan" is a fan that will be
# enabled whenever its associated heater or any configured stepper
# driver is active. The fan will stop, whenever an idle_timeout is
# reached to ensure no overheating will occur after deactivating a
# watched component.

#static_value:
#   If this is set, then the pin is assigned to this value at startup

#   This parameter can be used to alter how the 'value' and
#   'shutdown_value' parameters are interpreted for pwm pins. If

# containing two pins and then set "pin=multi_pin:my_fan" in the
# "[fan]" section - on each fan change both output pins would be
# updated. These aliases may not be used with stepper motor pins.

#diag1_pin:
#   The micro-controller pin attached to the DIAG1 line of the TMC5160

#   to configure this.

# Homing override. One may use this mechanism to run a series of
# g-code commands in place of a G28 found in the normal g-code input.
# This may be useful on printers that require a specific procedure to
# home the machine.
#[homing_override]
#gcode:
#   A list of G-Code commands to execute in place of G28 commands
#   found in the normal g-code input. See docs/Command_Templates.md

#   then it will invoke the normal homing procedure for the printer.
#   The commands listed here must home all axes. This parameter must
#   be provided.
#axes: xyz
#   The axes to override. For example, if this is set to "z" then the
#   override script will only be run when the z axis is homed (eg, via
#   a "G28" or "G28 Z0" command). Note, the override script should
#   still home all axes. The default is "xyz" which causes the
#   override script to be run in place of all G28 commands.
#set_position_x:
#set_position_y:
#set_position_z:
#   If specified, the printer will assume the axis is at the specified
#   position prior to running the above g-code commands. Setting this
#   disables homing checks for that axis. This may be useful if the
#   head must move prior to invoking the normal G28 mechanism for an
#   axis. The default is to not force a position for an axis.


# Support manually moving stepper motors for diagnostic purposes.
# Note, using this feature may place the printer in an invalid state -
# see docs/G-Codes.md for important details.
#[force_move]
#enable_force_move: False
#   Set to true to enable FORCE_MOVE and SET_KINEMATIC_POSITION
#   extended G-Code commands. The default is false.


# A virtual sdcard may be useful if the host machine is not fast

# standard sdcard G-Code commands (eg, M24).
#[virtual_sdcard]
#path: ~/.octoprint/uploads/
#   The path of the local directory on the host machine to look for

# between a set of configured temperature/voltage (or
# temperature/resistance) measurements to determine the
# temperature. The resulting sensor can be used as a sensor_type in a

#   prefix. Use this to define default values for g-code parameters.
#   For example, if one were to define the macro MY_DELAY with gcode
