Resonance Measurement
configure → other settings → Advanced options → Measuring Resonances
Select printer (moving print bed or static print bed)
connect sensor to sonic pad
Connect sensor to print head via bracket
Test takes about 3 minutes
detach sensor from print head and connect to print bed
sonic pad will reboot

disable slicer acceleration control (cura etc)

klipper added input_shaper section in printer.cfg

# [resonance_tester]
# accel_chip: adxl345
# accel_per_hz: 70
# probe_points:

[input_shaper]
#shaper_type_x = mzv
#shaper_freq_x = 56.4
#shaper_type_y = mzv
#shaper_freq_y = 36.2

  Determine if your printer has Z_HOMING_HEIGHT set. 
This setting raises the Z-axis on any homing event to avoid collisions. 
You can check your printer firmware configuration or in a resting state issue the command G28 X0 Y0 in the command terminal and observe if the Z-axis is raised, and by how much. This value is used for Z_HOMING_HEIGHT.
  The Save Frequency setting determines how often the plugin will write the current state information to disk in seconds. Lower values (0.3-0.5) provide greater accuracy at the expense of a greater number of disk writes. Larger values risk missing a greater number of commands.
  Klipper firmware. You must have the [force_move] section with the enable_force_move=true option in your Klipper configuration. Check the appropriate box in the settings. If [safe_z_home] is set, use the z_hop value as Z_HOMING_HEIGHT.
