X11 plus weird sound from motor

[papa_seleckis]

Yes, Sure you can, Okay I will redo the calibration.

[amilcarlucas]

Please use the files I provided.

Okay, I made everything you suggested, and looks really better than it was. what would be next step ?

[amilcarlucas]

The temperature calibration results are correct now.

I fixed a lot of stuff and created a “X11_plus” template on the tool. Please download install and use the latest 0.6.0 version

On the component editor:

Telemetry > FC Connection > Protocol - I think you want Mavlink 2
Battery > Specifications either the Chemistry is wrong or the voltage per cell are not correctly set.

I fixed a lot of stuff in the component editor please review it and re-do the configurations starting on file 05

I think the battery monitor BATT_AMP_PERVLT and BATT_VOLT_MULT are wrong.

I advise against EK3_SRC1_POSZ,3 and FS_EKF_ACTION

After re-doing all the steps 05 to 19 (and skipping 11) you can start on the 20 file.

and add a “vehicle.jpg” file with a photo of the vehicle.

After that send me the updated x11.zip file again

[papa_seleckis]

I have been updated your program, and now just turn on till components. i press save and start and ir turning off. I will fix telemetry, And about batt_amp_pervlt I don’t have device to measure it correctly. Okay, i will fix ek3 too. So now after all those I should takeoff from the ground?

@papa_seleckis

press save and start and it turning off

Thanks for the report, it was a python 3.10 issue. I have fixed it now. Download the new version

Here is information on how to calibrate.

Calibrate Amperes (Amperes per Volt) in Battery monitor settings without Amp Meter

Basic, only for dummies… I do not garantee this is the safest and accuratest way, but sometimes, with small light drones, like my test drone, it’s difficult to use the Ampmeter tool, values displayed fluctuate too much. This example for 3S 11.1V 3300mAh battery Full charge your battery. Connect to MP, select INITIAL SETUP…Optional Hardware…Battery Monitor and type your battery capacity (3300mAh). Look at the value in the field Amperes per Volt (default is 17) and remember it. Using a telemet…

Do not takeoff without correcting the points explained above and re-doing all the steps 05 to 19 (and skipping 11)

@amilcarlucas Hello again, Look like I pretty much done as much as I understand and could. I’m wondering later about quick tune, i saw there is for VTOL. can i use it? And I saw pid adjustment.py. I never used scripts before, how I could do so and which one would be okay, for my copter? Here is file.

zip: x11.zip

[amilcarlucas]

The Quicktune is for both VTOL aeroplanes and multicopters.

Yes, you can use it, it works great.

@papa_seleckis

And I saw pid adjustment.py

You do not need to use it because you did change the parameters by hand. I assume you tested the parameter changes you did in the 15_pid_adjustment.param file that I created with the values you had in the 0000087.bin file.

@papa_seleckis

I never used scripts before, how I could do so?

Again the trick is to read the 20_quick_tune_setup.param documentation links in the top of the ArduPilot Methodic Configurator and watch the video.

Thanks for the updated file.

[amilcarlucas]

Please:

1. delete your x11 vehicle directory
2. Download a new SW version from: Release Development Build · ArduPilot/MethodicConfigurator · GitHub
3. Install it
4. start the software and use the “X11_Plus” template to create a new “X11” vehicle directory
5. redo the steps bellow

I corrected some information in the following files:

• vehicle_componetns.json
• 07_esc.param
• 08_batt1.param
• 12_general_configuration.param
• 13_logging.param
• 14_motor.param
• 20_quick_tune_setup.param

[papa_seleckis]

I redid those, and the one thing on battery i didn’t do this is voltmultiplier, because of the power brick, i used to see that 26V not 2, and it will be harder for me. So i keep at 12.02. That’s works for me best. What our next step? Takeoff maybe? X11.zip | Files.fm.

[amilcarlucas]

@papa_seleckis

So i keep at 12.02

You do you mean? Please explain better.

You need to correct the voltmultiplier and the currentmultiplier and send me the corrected files.

The tool tells me that the last file that you uploaded is 14 but I think you need to also upload 17, 18 and 19.

After all that flight 20 is possible.

[papa_seleckis]

Here you go, I corrected everything, That one should be alright, I mean. So now i can takeoff ? X11.zip | Files.fm.

[amilcarlucas]

No you did not, the batt1 file has not changed

And is your MOT_THST_HOVER 0.2 or 0.13? That is not clear and is important for step 19

Did you fly for at least 30 seconds in ALT_HOLD mode in order for the FC to learn the MOT_THST_HOVER value?

Read section 3 again if you are unsure.
Impatience crashes vehicles.

@amilcarlucas Hello my friend, I got to takeoff and it was some problems, copter almost crashed and I got ek3 lane switch, but everything fine. After i put hover and made notch filter change, I took off Put althold and he started to lose position, random ups and downs, so I want to know what was source of that? What made him to do like this?

bin: 00000010.BIN and 2 other files

[dkemxr (Dave)]

@papa_seleckis

so I want to know what was source of that?

Not jumping into the tuning process here just observations and perhaps you have only touched the surface of this process in 3 days, but there is no Attitude or Rate logging. But there sure is a lot of Throttle Output oscillation…

Causing Motor Output jitter:

And, not that you can set the Notch Filter at this poor state of tune but there is no throttle data in the log for the filter analysis.

[amilcarlucas]

1. Voltage monitoring seams to be working, have you tested it with a multimeter?

2. Current Monitoring is not working. What current sensor do you have? How have you calibrated it?

3. Logging options are not fully correct:
   Add INS_RAW_LOG_OPT = 9 in the 13_logging.param file (set bits 0 and 3)
   upload the file to the FC.

4. I am not sure that MOT_THST_EXPO is correct for that Hobbywing ESC

5. What did you change in the notch filter? I do not see any Notch changes in the files.

[papa_seleckis]

1. Yes i measure it with multimeter. 2. I don’t have opportunity to measure current like I saw in the video. 3. I have been added your file to configurator. 4. this is not a T-Motor esc, this is hobbywing motor with esc already. 5. Yeah, I wasn’t made changes in your file, but it was in bin, I have been changed REF. X11.zip | Files.fm.

[papa_seleckis]

Okay, I see, We saw some thing going with eyes but little bit, seemed later it fixed it self, but after I put those values mot_thst_hover it happend with those ekf, sooo what I should do next? try to bring back values ir try another time?

[amilcarlucas]

2. If you do not have a current monitor, disable it.
   If you do have one, calibrate it and configure it. Almost all multimeters can measure at least 10A

Please change parameters only with the GUI, so that the files get saved. That is the point of this exercise!

Address point number 2 and provide an edited .zip file whenever you change a parameter.

Yes, I can extract the parameters from the .bin file, but I do not want to.

[papa_seleckis]

Okay, will do, I will change when i will be at home. So after fix number 2 I should go to test and takeoff?
