Vibration graph creation - IndexError: index -1 is out of bounds for axis 0 with size 0 about klippain-shaketune HOT 8 CLOSED

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

from klippain-shaketune.

Getting also this error message.

from klippain-shaketune.

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,

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 ?

from klippain-shaketune.

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.
