# This file serves as documentation for config parameters. One may
# copy and edit this file to configure a new cartesian style
# printer. For delta style printers, see the "example-delta.cfg"
# file. For corexy/h-bot style printers, see the "example-corexy.cfg"
# file. Only common config sections are described here - see the
# "example-extras.cfg" file for configuring less common devices.
# DO NOT COPY THIS FILE WITHOUT CAREFULLY READING AND UPDATING IT
# FIRST. Incorrectly configured parameters may cause damage.
# A note on pin names: pins may be configured with a hardware name
# (such as "PA4") or with an Arduino alias name (such as "ar29" or
# "analog3"). In order to use Arduino names, the pin_map variable in
# the mcu section must be present and have a value of "arduino".
# Pin names may be preceded by an '!' to indicate that a reverse
# polarity should be used (eg, trigger on low instead of high). Input
# pins may be preceded by a '^' to indicate that a hardware pull-up
# resistor should be enabled for the pin.
# The stepper_x section is used to describe the stepper controlling
# the X axis in a cartesian robot.
[stepper_x]

# Step GPIO pin (triggered high). This parameter must be provided.
dir_pin: ar55
# Direction GPIO pin (high indicates positive direction). This
# parameter must be provided.

# is 5mm.
#second_homing_speed:
# Velocity (in mm/s) of the stepper when performing the second home.
# The default is homing_speed/2.
#homing_positive_dir:
# If true, homing will cause the stepper to move in a positive
# direction (away from zero); if false, home towards zero. The
# default is true if position_endstop is near position_max and false

# Diameter of the nozzle orifice (in mm). This parameter must be
# provided.
filament_diameter: 3.500
# The nominal diameter of the raw filament (in mm) as it enters the
# extruder. This parameter must be provided.
#max_extrude_cross_section:
# Maximum area (in mm^2) of an extrusion cross section (eg,
# extrusion width multiplied by layer height). This setting prevents
# excessive amounts of extrusion during relatively small XY moves.
# If a move requests an extrusion rate that would exceed this value

# nozzle_diameter^2
#max_extrude_only_distance: 50.0
# Maximum length (in mm of raw filament) that a retraction or
# extrude-only move may have. If a retraction or extrude-only move
# requests a distance greater than this value it will cause an error
# to be returned. The default is 50mm.
#max_extrude_only_velocity:
#max_extrude_only_accel:
# Maximum velocity (in mm/s) and acceleration (in mm/s^2) of the
# extruder motor for retractions and extrude-only moves. These
# settings do not place any limit on normal printing moves. If not
# specified then they are calculated to match the limit an XY
# printing move with a cross section of 4.0*nozzle_diameter^2 would
# have.
#pressure_advance: 0.0
# The amount of raw filament to push into the extruder during
# extruder acceleration. An equal amount of filament is retracted
# during deceleration. It is measured in millimeters per
# millimeter/second. The default is 0, which disables pressure
# advance.
#pressure_advance_lookahead_time: 0.010
# A time (in seconds) to "look ahead" at future extrusion moves when
# calculating pressure advance. This is used to reduce the
# application of pressure advance during cornering moves that would
# otherwise cause retraction followed immediately by pressure
# buildup. This setting only applies if pressure_advance is
# non-zero. The default is 0.010 (10 milliseconds).
#
# The remaining variables describe the extruder heater.
heater_pin: ar10
# PWM output pin controlling the heater. This parameter must be
# provided.
#max_power: 1.0
# The maximum power (expressed as a value from 0.0 to 1.0) that the
# heater_pin may be set to. The value 1.0 allows the pin to be set
# fully enabled for extended periods, while a value of 0.5 would
# allow the pin to be enabled for no more than half the time. This
# setting may be used to limit the total power output (over extended
# periods) to the heater. The default is 1.0.

# Analog input pin connected to the sensor. This parameter must be
# provided.
#pullup_resistor: 4700
# The resistance (in ohms) of the pullup attached to the
# thermistor. This parameter is only valid when the sensor is a
# thermistor. The default is 4700 ohms.
#adc_voltage: 5.0
# The ADC comparison voltage. This parameter is only valid when the
# sensor is an AD595 or "PT100 INA826". The default is 5 volts.
#smooth_time: 2.0
# A time value (in seconds) over which temperature measurements will
# be smoothed to reduce the impact of measurement noise. The default
# is 2 seconds.
control: pid
# Control algorithm (either pid or watermark). This parameter must
# be provided.
pid_Kp: 22.2
# Kp is the "proportional" constant for the pid. This parameter must
# be provided for PID heaters.
pid_Ki: 1.08
# Ki is the "integral" constant for the pid. This parameter must be

# is to use the same value as max_power.
#pwm_cycle_time: 0.100
# Time in seconds for each software PWM cycle of the heater. It is
# not recommended to set this unless there is an electrical
# requirement to switch the heater faster than 10 times a second.
# The default is 0.100 seconds.
#min_extrude_temp: 170
# The minimum temperature (in Celsius) at which extruder move
# commands may be issued. The default is 170 Celsius.
min_temp: 0
max_temp: 210
# The maximum range of valid temperatures (in Celsius) that the
# heater must remain within. This controls a safety feature
# implemented in the micro-controller code - should the measured
# temperature ever fall outside this range then the micro-controller
# will go into a shutdown state. This check can help detect some
# heater and sensor hardware failures. Set this range just wide
# enough so that reasonable temperatures do not result in an
# error. These parameters must be provided.
# The heater_bed section describes a heated bed (if present - omit
# section if not present).
[heater_bed]
heater_pin: ar8
sensor_type: EPCOS 100K B57560G104F
sensor_pin: analog14
control: watermark
#max_delta: 2.0
# On 'watermark' controlled heaters this is the number of degrees in
# Celsius above the target temperature before disabling the heater
# as well as the number of degrees below the target before
# re-enabling the heater. The default is 2 degrees Celsius.
min_temp: 0

# Print cooling fan (omit section if fan not present).
[fan]
pin: ar9
# PWM output pin controlling the fan. This parameter must be
# provided.
#max_power: 1.0
# The maximum power (expressed as a value from 0.0 to 1.0) that the
# pin may be set to. The value 1.0 allows the pin to be set fully
# enabled for extended periods, while a value of 0.5 would allow the
# pin to be enabled for no more than half the time. This setting may
# be used to limit the total power output (over extended periods) to
# the fan. If this value is less than 1.0 then fan speed requests
# will be scaled between zero and max_power (for example, if
# max_power is .9 and a fan speed of 80% is requested then the fan
# power will be set to 72%). The default is 1.0.
#shutdown_speed: 0
# The desired fan speed (expressed as a value from 0.0 to 1.0) if
# the micro-controller software enters an error state. The default
# is 0.
#cycle_time: 0.010
# The amount of time (in seconds) for each PWM power cycle to the
# fan. It is recommended this be 10 milliseconds or greater when
# using software based PWM. The default is 0.010 seconds.
#hardware_pwm: False
# Enable this to use hardware PWM instead of software PWM. The
# default is False.
#kick_start_time: 0.100
# Time (in seconds) to run the fan at full speed when first enabling
# it (helps get the fan spinning). The default is 0.100 seconds.
# Micro-controller information.
[mcu]
serial: /dev/ttyACM0
# The serial port to connect to the MCU. If unsure (or if it
# changes) see the "Where's my serial port?" section of the FAQ. The
# default is /dev/ttyS0
#baud: 250000
# The baud rate to use. The default is 250000.
pin_map: arduino
# This option may be used to enable Arduino pin name aliases. The
# default is to not enable the aliases.
#restart_method:
# This controls the mechanism the host will use to reset the
# micro-controller. The choices are 'arduino', 'rpi_usb', and
# 'command'. The 'arduino' method (toggle DTR) is common on Arduino
# boards and clones. The 'rpi_usb' method is useful on Raspberry Pi
# boards with micro-controllers powered over USB - it briefly
# disables power to all USB ports to accomplish a micro-controller
# reset. The 'command' method involves sending a Klipper command to
# the micro-controller so that it can reset itself. The default is
# 'arduino' if the micro-controller communicates over a serial port,
# 'command' otherwise.
# The printer section controls high level printer settings.
[printer]
kinematics: cartesian
# This option must be "cartesian" for cartesian printers.
max_velocity: 500
# Maximum velocity (in mm/s) of the toolhead (relative to the
# print). This parameter must be specified.
max_accel: 3000
# Maximum acceleration (in mm/s^2) of the toolhead (relative to the
# print). This parameter must be specified.
#max_accel_to_decel:
# A pseudo acceleration (in mm/s^2) controlling how fast the
# toolhead may go from acceleration to deceleration. It is used to
# reduce the top speed of short zig-zag moves (and thus reduce
# printer vibration from these moves). The default is half of
# max_accel.
max_z_velocity: 25
# For cartesian printers this sets the maximum velocity (in mm/s) of
# movement along the z axis. This setting can be used to restrict
# the maximum speed of the z stepper motor on cartesian
# printers. The default is to use max_velocity for max_z_velocity.
max_z_accel: 30
# For cartesian printers this sets the maximum acceleration (in
# mm/s^2) of movement along the z axis. It limits the acceleration
# of the z stepper motor on cartesian printers. The default is to
# use max_accel for max_z_accel.
#square_corner_velocity: 5.0
# The maximum velocity (in mm/s) that the toolhead may travel a 90
# degree corner at. A non-zero value can reduce changes in extruder
# flow rates by enabling instantaneous velocity changes of the
# toolhead during cornering. This value configures the internal
# centripetal velocity cornering algorithm; corners with angles
# larger than 90 degrees will have a higher cornering velocity while
# corners with angles less than 90 degrees will have a lower
# cornering velocity. If this is set to zero then the toolhead will
# decelerate to zero at each corner. The default is 5mm/s.
