# 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
# endstop will home until the endstop on the primary stepper for the
# axis is triggered.
# 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. In the event of an MCU
