Measure_linear_vibrations_range ERROR!

was doing some testing....

measures_linear_vibrations_range axis=x vmin=50 vmax=300 step=25

measures_linear_vibrations_range axis=x vmin=50 vmax=300 step=25

Tests ran fine, and generated three graphs in the /home/pi/printer_data/config/linear_vibration folder peak_frequencies_logscale2023-03-15T10:54:15.207785.png peak_frequencies2023-03-15T10:54:15.207744.png relative_power2023-03-15T10:54:14.725170.png Then the machine reset with an error see attached klippy log c-a-p (attached here) printer.cfg section was simply

accel_chip: adxl345
x_min: 50
x_max: 450
y_min: 50
y_max: 450
output_directory: /home/pi/printer_data/config/linear_vibration/

accel_chip: adxl345
x_min: 50
x_max: 450
y_min: 50
y_max: 450
output_directory: /home/pi/printer_data/config/linear_vibration/

and there are three files there in that directory as listed above. This is RO v2 on a VC500. Test appeared to (mechanically) run fine. I'm not sure why it would come up with the typical orange text system error...fix and reset screen (parts cooling fan sent to full power etc needing a reboot to continue) anyone run into this? or is the 'range' test not functional under R) v2?

Your adxl345 isn't responding try ACCELEROMETER_QUERY

ptegler•2y ago

accelerometer values (x, y, z): -296.082377, -666.185348, 10955.165621 isn't ther a noice test? noise

Axes noise for xy-axis accelerometer: 15.192091 (x), 15.945923 (y), 24.867745 (z)

miklschmidt•2y ago

Nothing wrong there

ptegler•2y ago

as previously mentioned...test ran then messed up at the end. Is it three, or four graphs?

miklschmidt•2y ago

Is it possible it lost connection midway? Is the wire/connectors properly secured etc?

ptegler•2y ago

perhaps a spot of hot glue on the connector

miklschmidt•2y ago

But the error in your klipper.log says "gcode.CommandError: Unable to obtain 'adxl345_status' response"

ptegler•2y ago

(to make sure is stays connected) Internal error on command:"MEASURE_LINEAR_VIBRATIONS_RANGE" 1:15 PM Klipper state: Shutdown 1:15 PM output written to /home/pi/printer_data/config/linear_vibration/peak_frequencies_logscale2023-03-15T13:15:14.278438.png 1:15 PM output written to /home/pi/printer_data/config/linear_vibration/peak_frequencies2023-03-15T13:15:14.278397.png 1:15 PM output written to /home/pi/printer_data/config/linear_vibration/relative_power2023-03-15T13:15:13.818979.png

ptegler•2y ago

basically the same as before. Three new files,then errors

ptegler•2y ago

possible .py file corruption?

miklschmidt•2y ago

There's nothing wrong with the .py file then the parser would error out. This here is an adxl345_status error, as in, it can't query your adxl345. Not sure why. It's not impossible it's a bug, but it doesn't look that way. @MarschallMarc any ideas?

ptegler•2y ago

does seem odd as the first three run just fine

miklschmidt•2y ago

indeed

ptegler•2y ago

data query anyway... perhaps a faulty ADXL? status query not working vs data query but you'd think it would query completion status between runs

miklschmidt•2y ago

There's another thread here with a guy reporting the exact same problem

ptegler•2y ago

saw that

miklschmidt•2y ago

So it's probably a bug 😄

ptegler•2y ago

crap.

miklschmidt•2y ago

Yeah we'd need to wait for upstream fixes from @MarschallMarc

ptegler•2y ago

surprised noone else has hit it. Wahts the diff in the single run vs this 'range' run

miklschmidt•2y ago

I believe i promised him to run it on my machine, but i didn't do that yet

miklschmidt•2y ago

ptegler•2y ago

...t'was where I started 🙂 I remembered though you'd incorporated it in V2 let go run the 'single' and see what it does

ptegler•2y ago

will have to check my wires/chip

marschallmarc•2y ago

I didn't check it with the latest klipper updates, so might be sth going on there Promised might be too strong, but you agreed to do it 😋 That one however is not related to my stuff, I think It basically sais what is happening

ptegler•2y ago

wires all good.... ran single ..got the error above.... re-ran 'range' and it repeated as first proposed in this thread

marschallmarc•2y ago

This can also be when it errors out. It doesnt handle it well that we lock the device but don't release it on error I cannot read the file on my mobile rn, but I will see if there is an earlier error happening

ptegler•2y ago

full log...should show all attempt errors ( single vibe and range vibe attempts

klippy14.log

marschallmarc•2y ago

Klipper really needs a mode where it does less logging... Every freaking second full status report is insane

ptegler•2y ago

yep the mcu updates are nuts

marschallmarc•2y ago

Its an error with the plot in matplotlib Invalid axis z

ptegler•2y ago

wow

marschallmarc•2y ago

Yep, line 422 Which is caused by different versions of matplotlib between what was installed when I developed it and which is installed now Easy fix though @miklschmidt #debuggingCodeUsingASmartPhoneButWhy

miklschmidt•2y ago

What do? 😄

marschallmarc•2y ago

Well, basically just read the matplotlib docu and correct the plot command. It was the py2 vs py3 thingy here... its just a command to set the ticklables thats going rouge In my next life I will learn to use the answer button, I swear

miklschmidt•2y ago

the plot command? so a change to the plugin? that requires commit access to your repository 😄

marschallmarc•2y ago

I will just do it

miklschmidt•2y ago

Very nice! 😄

marschallmarc•2y ago

so ppl can also just use the update button and its ok

miklschmidt•2y ago

indeed

marschallmarc•2y ago

just need to setup a new klipper pi quickly to test before release 😛

ptegler•2y ago

just updated Klipper now a different error! klippy.log

ptegler•2y ago

x homed and it just stopped. Now neither single nor range run

blacksmithforlife•2y ago

perhaps your wiring has gone loose? It happened to me, after all the high speed movements the wires near my soldering had stress cracked and broken off

ptegler•2y ago

just finished ohming out my harness...tugged and wiggled...no breaks good continuity . Rebooted (full power down/power up) Homed all axis ran MEASURE_AXES_NOISE just to test. All was well. Ran measure_linear_vibrations axis=x vmin=50 vmax=300 step=25 No error this time, but it only wrote one file. The final multi spike graph that it was not running before. Carriage only made one pass

ptegler•2y ago

repeated the entire routine...same thing. Now it only runs one X axis move and prints one graph

printer3.cfg

klippy15.log

ptegler•2y ago

klippy log shortened to just the last reboot see attached. making litle to no sense as all this worked. I was getting 3 graphs, then would F up on the fourth. Now I'm only getting the four

ptegler•2y ago

just ran the 'range'

ptegler•2y ago

only wrote three files

ptegler•2y ago

@miklschmidt Q? an 'update' would over-write any possible bad *.py file is included in an update correct? Just wondering if i have a bad TF card or something else is going on. belt tension, adxl noise test and input shaper all work just fine. It's just the linear vibration stuff that is a no-go. I saw the Klipper update, but didn't seem to change anything. or--- am I jumping the gun...updates/corrections still in process?

miklschmidt•2y ago

yes. You don't have bad python files though, it wouldn't make it as far as it does. Like marc said there's a bug in the linear vibration plugin, he will fix it.

ptegler•2y ago

tnx...guees that was what i was wondering..the most recent (earlier this afternoon) Klpper update was not/did not include the fix.

miklschmidt•2y ago

No, like i said it's a plugin You can see it in the update manager

ptegler•2y ago

👍

miklschmidt•2y ago

There'll be an update to this as soon as marc gets it done. That'll fix it.

marschallmarc•2y ago

Yep, but the wrong ID thingy I am pretty sure does not come from my plugin. That's hardware related

ptegler•2y ago

that's been straightened out at this end. After testing the wiring for faults, I'd plugged it back in wrong. Belt tension, adxl noise, input shaper all work properly , so i'm comfortable the ADXL itself is fine. thanks for your attention to all this MM !

blacksmithforlife•2y ago

I hate plugs that allow you to plug them in wrong

ptegler•2y ago

instead of duponts, I've recently considered flyleading a XL or PH connector to that ADXL board for that very reason as I usually pull back those wires to reduce umbilical weight when the ADXL is not needed

miklschmidt•2y ago

I use JST-XH on all of mine

ptegler•2y ago

hehe one of many stacks....

ptegler•2y ago

any progress on fixing this plug-in? bump? Is this RO v2 included asset being fixed? or is it a dead effort? I see on github, a few others have seen this issue as well (fortuh graph does not run)

miklschmidt•2y ago

@MarschallMarc

marschallmarc•2y ago

Its on my this weeks todo list

ptegler•2y ago

Thanks for the update!

Joao Barros•2y ago

If confirmation was needed, I'm being bitten by the same issue too

marschallmarc•2y ago

Fixed

Joao Barros•2y ago

Thanks, will test tonight 🙂

ptegler•2y ago

just updated....it all works now thanks for the efforts @Marschall Marc

marschallmarc•2y ago

More to come with that one. A few ideas brewing 😛

genetic-orange•2y ago

hello marc, there are also instructions on how to interpret the graphs

marschallmarc•2y ago

Adding a few features within the next 2 to 3 weeks, after that I will do that. but to be honest, on some things we will learn over time seing more data over time as well 😄

tg73•3mo ago

@Marschall Marc @miklschmidt I'm trying to use measure_linear_vibrations_range (mlvr) with the current updated ratos 2.1 rc. After the command writes 3 graph images, klipper shuts down. The 3d plot shown in the klipper_linear_movement_analysis (klma) readme is not generated. I've tried both main and development branches of klma, same behaviour. Please let me know if you'd rather see this as a separate issue. It appears to originate with this exception (klma development branch):

marschallmarc•3mo ago

I cannot verify the issue, as I am away from printers for a couple of more days at least. It looks like the plot fails, because the data are not as the plot function expects them. It is possible that the latest klipper version is not compatible, I did not track the changes. If generating the graphs for IS still works as expected, it very well may be an issue with klma (never saw this acronym before :P). However, I cannot imagine this being a hard fix, if it is the case. There is not much complexity to it

tg73•3mo ago

Thanks for the prompt reply! Other graphs (regular klipper ones and klippain shake tune) work as expected. I might try to comment out the offending graph generation for now - I am a coder, but not python and notably I don't have domain familiarity. Kinda-fixed/fudged by me in https://github.com/tg73/klipper_linear_movement_analysis/tree/fix-np. The 3d chart is now generated but lacks colour per velocity. But it doesn't crash. Just a sticking plaster applied dumbly without understanding the consequences.

marschallmarc•3mo ago

Thanks. I will have a look, I would prefer to not lose features on PR though. To be perfectly honest, I almost remember nothing about the implementation :kekw:
