### [smart_effector]
Smart Effector. One may define this section instead of `[probe]` to enable
the SmartEffector-specific features. This also enables
[runtime commands](G-Codes.md#smart-effector) to adjust the parameters of
the Smart Effector at run time.
```
[smart_effector]
pin:
# Pin connected to the Smart Effector Z Probe output pin (pin 5). Note that
# pullup resistor on the board is generally not required. However, if the
# output pin is connected to the board pin with a pullup resistor, that
# resistor must be high value (e.g. 10K Ohm or more). Some boards have a low
# value pullup resistor on the Z probe input, which will likely result in an
# always-triggered probe state. In this case, connect the Smart Effector to
# a different pin on the board. This parameter is required.
# control_pin:
# Pin connected to the Smart Effector control input pin (pin 7). If provided,
# Smart Effector sensitivity programming commands become available.
# probe_accel:
# If set, limits the acceleration of the probing moves (in mm/sec^2).
# A sudden large acceleration at the beginning of the probing move may
# cause spurious probe triggering, especially if the hotend is heavy.
# To prevent that, it may be necessary to reduce the acceleration of
# the probing moves via this parameter.
# recovery_time: 0.4
# A delay between the travel moves and the probing moves in seconds. A fast
# travel move prior to probing may result in a spurious probe triggering.
# This may cause 'Probe triggered prior to movement' errors if no delay
# is set. Value 0 disables the recovery delay.
# Default value is 0.4.
#x_offset:
#y_offset:
# Should be left unset (or set to 0).
z_offset:
# Trigger height of the probe. Start with -0.1 (mm), and adjust later using
# `PROBE_CALIBRATE` command. This parameter must be provided.
#speed:
# Speed (in mm/s) of the Z axis when probing. It is recommended to start
# with the probing speed of 20 mm/s and adjust it as necessary to improve
# the accuracy and repeatability of the probe triggering.
#samples:
#sample_retract_dist:

#samples_tolerance:
#samples_tolerance_retries:
#activate_gcode:
#deactivate_gcode:
#deactivate_on_each_sample:

### [smart_effector]
Several commands are available when a
[smart_effector config section](Config_Reference.md#smart-effector) is enabled.
Be sure to check the official documentation for the Smart Effector on the
[Duet3D Wiki](https://duet3d.dozuki.com/Wiki/Smart_effector_and_carriage_adapters_for_delta_printer)
before changing the Smart Effector parameters. Also check the
[probe calibration guide](Probe_Calibrate.md).
#### SET_SMART_EFFECTOR
`SET_SMART_EFFECTOR [SENSITIVITY=<sensitivity>] [ACCEL=<accel>]
[RECOVERY_TIME=<time>]`: Set the Smart Effector parameters. When `SENSITIVITY`
is specified, the respective value is written to the SmartEffector EEPROM
(requires `control_pin` to be provided). Acceptable <sensitivity> values are
0..255, the default is 50. Lower values require less nozzle contact force to
trigger (but there is a higher risk of false triggering due to vibrations
during probing), and higher values reduce false triggering (but require larger
contact force to trigger). Since the sensitivity is written to EEPROM, it is
preserved after the shutdown, and so it does not need to be configured on
every printer startup. `ACCEL` and `RECOVERY_TIME` allow to override the
corresponding parameters at run-time, see the
[config section](Config_Reference.md#smart-effector) of Smart Effector for
more info on those parameters.
#### RESET_SMART_EFFECTOR
`RESET_SMART_EFFECTOR`: Resets Smart Effector sensitivity to its factory
settings. Requires `control_pin` to be provided in the config section.
### [stepper_enable]
The stepper_enable module is automatically loaded.
