Example klicky-z-calibration configuration for the Voron 2.4 with Klicky probe (don't forget to include it in your klicky-probe.cfg)

klicky-z-calibration.cfg

[z_calibration]

## update these variable according to the documentation here https://github.com/protoloft/klipper_z_calibration
## you then should call CALIBRATE_Z as one of the last lines on your PRINT_START to set the Z offset dinamically

#   The X and Y coordinates (in mm) for clicking the nozzle on the
#   Z endstop.
nozzle_xy_position: X,Y
#   The X and Y coordinates (in mm) for clicking the probe's switch body
#   on the Z endstop.
switch_xy_position: X,Y
#   The X and Y coordinates (in mm) for probing on the print surface
#   (e.g. the center point) These coordinates will be adapted by the
#   probe's X and Y offsets. The default is the relative_reference_index
#   of the configured bed_mesh. It will raise an error if there is no
#   probe_bed site and no bed_mesh with a relative_reference_index
#   configured.
#bed_xy_position: X,Y
#   The trigger point offset of the used switch.
#   This needs to be fined out manually. For more details go to 
#   https://github.com/protoloft/klipper_z_calibration#switch-offset
#   "So, with a smaller offset value, the nozzle is more away from the 
#   bed! The value cannot be negative."
switch_offset: 0.45
#   The maximum allowed deviation of the calculated offset.
#   If the offset exceeds this value, it will stop!
#   The default is 1.0 mm.
max_deviation: 1.5
#   The number of times to probe each point. The probed z-values
#   will be averaged. The default is from the probe's configuration.
#samples: default from "probe:samples" section
#   The maximum Z distance (in mm) that a sample may differ from other
#   samples. The default is from the probe's configuration.
#samples_tolerance: default from "probe:samples_tolerance" section
#   The number of times to retry if a sample is found that exceeds
#   samples_tolerance. The default is from the probe's configuration.
#samples_tolerance_retries: default from "probe:samples_tolerance_retries" section
#   The calculation method when sampling more than once - either
#   "median" or "average". The default is from the probe's configuration.
#samples_result: default from "probe:samples_result" section
#   The distance in mm to move up before moving to the next
#   position. The default is two times the z_offset from the probe's
#   configuration.
clearance: 7.5
#position_min: default from "stepper_z:position_min" section.
#   The moving speed in X and Y. The default is 50 mm/s.
speed: 200
#   Speed (in mm/s) of the Z axis when lifting the probe between
#   samples and clearance moves. The default is from the probe's
#   configuration.
#lift_speed: default from "probe:lift_speed" section
#   The fast probing speed (in mm/s) used, when probing_first_fast
#   is activated. The default is from the Z rail configuration.
#probing_speed: default from "stepper_z:homing_speed" section.
#   The slower speed (in mm/s) for probing the recorded samples.
#   The default is second_homing_speed of the Z rail configuration.
#probing_second_speed: default from "stepper_z:second_homing_speed" section.
#   Distance to back off (in mm) before probing the next sample.
#   The default is homing_retract_dist from the Z rail configuration.
#probing_retract_dist: default from "stepper_z:homing_retract_dist" section.
#   If true, the first probing is done faster by the probing speed.
#   This is to get faster down and the result is not recorded as a
#   probing sample. The default is false.
probing_first_fast: true
#   If true, the first probing is done faster by the probing speed.
#   This is to get faster down and the result is not recorded as a
#   probing sample. The default is false.

start_gcode: Dock_Probe_Unlock
#   A list of G-Code commands to execute prior to each calibration command.
#   See docs/Command_Templates.md for G-Code format. This can be used to
#   attach the probe.
before_switch_gcode: Attach_Probe
#   A list of G-Code commands to execute prior to each probing on the
#   mag-probe. See docs/Command_Templates.md for G-Code format. This can be
#   used to attach the probe after probing on the nozzle and before probing
#   on the mag-probe.
end_gcode: Dock_Probe
#   A list of G-Code commands to execute after each calibration command.
#   See docs/Command_Templates.md for G-Code format. This can be used to
#   detach the probe afterwards.
