Describe your issue:

Hello, I used TEST_RESONANCES AXIS=X followed by save_config for automatic Input Shaping of the X axis. Similarly, TEST_RESONANCES AXIS=Y followed by save_config for the Y-axis. When I opened the printer.cfg file, I found that at the bottom there are:

#*# [input_shaper]
#*# shaper_type_x = ei
#*# shaper_freq_x = 40.8
#*# shaper_type_y = mzv
#*# shaper_freq_y = 34.8

Is that all for Input Shaping?

Am I supposed to remove all the #*#? I recall that in other topics, we were told not to uncomment those green information under save_config but if the Input Shaping data are commented, how Klipper knows and uses the result of Input Shaping?

A confusion is that a youtuber used TEST_RESONANCES AXUS=X and TEST_RESONANCES AXUS=Y for Input Shaping. Then, he manually analyzed the data and created a [input_shaper] section in printer.cfg. Then, entered values for these four parameters without # at the beginning of each line.

That are the results of the measurement. Klipper puts those things there.

Also:

#*# <---------------------- SAVE_CONFIG ---------------------->
#*# DO NOT EDIT THIS BLOCK OR BELOW. The contents are auto-generated.

Can Klipper read those measurements given that they have # at the beginning of the line?
What is #*# anyway?

@printeruser ,

The #*# is how Klipper denotes saved configuration variables. Klipper can and does read those lines without an issue.
