klipper/config/example.cfg

# 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.

# 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_pin: ar29
#   Step GPIO pin (triggered high)
dir_pin: !ar28
#   Direction GPIO pin (high indicates positive direction)
enable_pin: !ar25
#   Enable pin (default is enable high; use ! to indicate enable low)
step_distance: .0225
#   Distance in mm that each step causes the axis to travel
max_velocity: 500
#   Maximum velocity (in mm/s) of the stepper
max_accel: 3000
#   Maximum acceleration (in mm/s^2) of the stepper
endstop_pin: ^ar0
#   Endstop switch detection pin
homing_speed: 50.0
#   Maximum velocity (in mm/s) of the stepper when homing
homing_retract_dist: 5.0
#   Distance to backoff (in mm) before homing a second time during homing
homing_positive_dir: False
#   If true, homes in a positive direction (away from zero)
homing_stepper_phases: 0
#   One may optionally set this to the number of phases of the stepper
#   motor driver (which is the number of micro-steps multiplied by
#   four). When set, the phase of the stepper driver will be used
#   during homing to improve the accuracy of the endstop switch.
homing_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). This setting is used with
#   homing_stepper_phases and is only useful if that parameter is also
#   configured.
#homing_endstop_phase: 0
#   This specifies the phase of the stepper motor driver to expect
#   when hitting the endstop. This setting is only meaningful if
#   homing_stepper_phases is also set. 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, but homing_stepper_phases is set, then
#   the stepper phase will be detected on the first home and that
#   phase will be used on all subsequent homes.
