Questions about the input shaping plugin

@gixxerfast that's strange... I did the same test and it works. You are on 3.4 B6? Can you confirm via M122?

@gixxerfast strange. I have done the manual method of Klipper for getting the frequency of the ringing. Can you try this aswell.
-
@pcr I'll see if I can do that a bit later if I find the instructions
It doesn't look like "MZV" is working very good here
Also seem like the plugin is leaving the last m593 setting. I could end with a M593 "none" or the before-value instead.

@gixxerfast
From the photos it looks like either the commands failed or there were other settings preventing the modes from working.Watch the console/display for any errors. It looks like those commands are fine but I've had errors returned for copy/pasted commands that include quotation marks. Alternatively, you can verify the IS mode is being set correctly by running "M593" in the console during each 5mm part of the print.
I don't know what your other settings are so I'll state the following:
For testing the IS modes you should first be sure pressure advance has been disabled, set your accelerations (M201,M204) to 10000 for X&Y and jerk (M566) to 300 for X&Y. The print speed should be between 50-80mm/s (too slow and ringing artifacts are too close together, but too fast and they start getting smeared out and less pronounced).Hopefully this is helpful

Did you get anywhere with this? I am in exact same boat (1LC+6HC on latest stable RRF 3.4.0)
-
@leobg and @Gixxerfast both RRF and the input shaping plugin have changed substantially since the original posts 6 months ago. Please try using RRF 3.4.0 or 3.4.1rc1 and the latest input shaping plugin, and start a new thread if the problem persists.
Additionally, tThe snapshot of the graph in the original post was lacking the frequency scale, so I can't tell how the configured M593 parameters relate to the graph.

Friends,
I have the accelerometer installed and I speak the readings successfully using the imput shaping plugin 3.4.0 b1.
after reading without input modeling, I apply some modeling to analyze the result, and they don't look good, I don't know if I'm doing something wrong or my mechanics are not good enough.
I'll put images in the correct order, from the data collections made by the plugin.
the interesting thing is that the plugin simulates the expected result with the input modeling, in these simulations the results seem very good, but when I collect data using the input modeling the actual results collected are not as good as the simulations.No shaper

please help me understand if i'm doing something wrong or there might be something wrong with my firmware.
I'm using jerk of 300mm/min and accelerations of 3500mm/s2the accelerometer is fixed this way
Thank you for your help!

@rodokas in the screen shot of your configuration file,
- the M593 is prepended with a semicolon,
- You are using upper case for the algorithm in the P parameter
- ou are using a colon to separate the decimal point in the F parameter. The former means the command is not read at all, the latter is not the right way to input the value.
Change
;M593 P"ZVDDD" F40,9to
M593 P"zvddd" F40.9and try again.

@rodokas Hi friend, thanks for trying to help. where you mentioned that you have ; I was in tests, and I'm using the plugin, that screenshot was just to show how it's placed because the accelerometer code.
I'm doing everything inside the plugin, so at this point I don't need to worry about the 593 in the config.
all tests inside the plugin also go wrong. -
@rodokas I can only work with what I see (-;
