Vibration graph creation - IndexError: index -1 is out of bounds for axis 0 with size 0

[Henk72]

K-Shake&Tune module branch

• [X] I confirm using the main branch

Version

v2.5.0-7-gb42e377a

Describe the bug and expected behavior

When running vibration analysis the printer is measuring correctly, but the scripts that make a graph .png file fail with attached error. This happens on my Ender5Pro. On the Ender3v2 all is working as expected.

Could this be related to the fact that the Ender5Pro homes against the max values of the axis (corner right/back) instead of the the Ender3v2 which homes in corner front left (0,0).

Additional information and klippy.log

Got exactly same error on ender 3 with K-Shaketune 2.6.0. Might be some cache issue, it was working fine until it randomly stopped working

Getting also this error message.

I'm not sure about the origin of this error message since it should be an impossible case... Can you share the CSV file that produce this error?

Hi,

I have the same problem,

printer.cfg [stepper_x] ... position_endstop:260 ... [stepper_y] ... position_endstop: 150 ...

Klippain-version: v2.6.0-2-g312a9c9f Klipper-version: v0.12.0-115-gb98375b3

I retested today with the latest version. I got next error again

"motor_fr, motor_zeta, motor_max_power_index = compute_mechanical_parameters(motor_vibration_power, freqs) File "/home/pi/Ender5Pro_data/config/K-ShakeTuneJos/scripts/common_func.py", line 81, in compute_mechanical_parameters"

"idx_below = np.where(psd[:max_power_index] <= half_power)[0][-1] IndexError: index -1 is out of bounds for axis 0 with size 0"

I have attached the most recent .csv file from all the generated ones.

@hrvat94 your issue is different and it's because you have updated Shake&Tune to v2.6 and will need to also update Klipper to a more recent version. This will fix your issue. I hid your comment to keep the topic on the current issue.

@Henk72 and @hemasi3d can you give me the full set of CSV files in a zip archive ?

[Henk72]

Dear Frix-x,

This is my full set of CSV files zipped. The problem happens on the Y-axis of the Ender5Pro. No issues on my Ender3v2. vibrations.zip

Hello, this was fixed in v3 and should not happen anymore :)
