klipper-dgus/config/generic-replicape.cfg

# This file contains an example configuration for the Replicape rev B3
# board. To use this config, one must compile and install the
# micro-controller code for the "Beaglebone PRU", and then compile and
# install the micro-controller code a second time for a "Linux
# process".

# NOTE: Klipper does not alter the input/output state of the
# Beaglebone pins and it does not control their pull-up resistors.
# Typically the correct settings are automatically applied when the
# Beaglebone detects the Replicape board, but if changes are needed
# they must be specified in a "device tree overlay" or via the
# config-pin program.

# See the example.cfg file for a description of available parameters.

# The "replicape" config section adds "replicape:stepper_x_enable"
# virtual stepper enable pins (for steppers x, y, z, e, and h) and
# "replicape:power_x" PWM output pins (for hotbed, e, h, fan0, fan1,
# fan2, and fan3) that may then be used elsewhere in the config file.
[replicape]
revision: B3
#   The replicape hardware revision. Currently only revision "B3" is
#   supported. This parameter must be provided.
#enable_pin: !P9_41
#   The replicape global enable pin. The default is !P9_41.
host_mcu: host
#   The name of the mcu config section that communicates with the
#   Klipper "linux process" mcu instance. This parameter must be
#   provided.
#standstill_power_down: False
#   This parameter controls the CFG6_ENN line on all stepper
#   motors. True sets the enable lines to "open". The default is
#   False.
stepper_x_microstep_mode: spread16
#   This parameter controls the CFG1 and CFG2 pins of the given
#   stepper motor driver. Available options are: disable, 1, 2,
#   spread2, 4, 16, spread4, spread16, stealth4, and stealth16. The
#   default is disable.
stepper_x_current: 0.5
#   The configured maximum current (in Amps) of the stepper motor
#   driver. This parameter must be provided if the stepper is not in a
#   disable mode.
#stepper_x_chopper_off_time_high: False
#   This parameter controls the CFG0 pin of the stepper motor driver
#   (True sets CFG0 high, False sets it low). The default is False.
#stepper_x_chopper_hysteresis_high: False
#   This parameter controls the CFG4 pin of the stepper motor driver
#   (True sets CFG4 high, False sets it low). The default is False.
#stepper_x_chopper_blank_time_high: True
#   This parameter controls the CFG5 pin of the stepper motor driver
#   (True sets CFG5 high, False sets it low). The default is True.
