Crowsnest uninstall and reinstall issues | Mainsail | Page 1

Hey community. I was trying to setup, what should have been a fairly simple C920 USB camera to work on my Voron 2.4 running Klipper/Mainsail/Fluid/Crowsnest. I apologize if I am not using the correct terms.

The camera would come up at first, but then stop working. The log file say this at the bottom:

[01/10/23 15:15:04] crowsnest: V4L2 Control:
[01/10/23 15:15:05] crowsnest: No parameters set for [cam 1]. Skipped.
[01/10/23 15:15:05] crowsnest: Try to start configured Cams / Services...
[01/10/23 15:15:05] crowsnest: INFO: Configuration of Section [cam 1] looks good. Continue...
[01/10/23 15:15:06] crowsnest: Starting ustreamer with Device /dev/video0 ...
[01/10/23 15:15:06] crowsnest: ERROR: Start of ustreamer [cam 1] failed!
[01/10/23 15:15:07] crowsnest: ... Done!

I found the info on the github page so I tried to unistall crowsnest, but it would not because the dir was not empty? So, I tried to manually remove files/directories, etc. I tried the uninstall instructions, but was getting error as well. I tired to execute the make new build command and I get errors as well (see below):

pi@voron205:~ $ cd ~/crowsnest
pi@voron205:~/crowsnest $ make buildclean
make: *** No rule to make target 'buildclean'. Stop.
pi@voron205:~/crowsnest $

I am looking to get back to the correct crowsnest state (new install) so hopefully I can get a simple USB webcam to work. Any help would be greatly appreciated.

Cheers,

As a follow up, I am not the most savvy when it comes to SSH…so please be patient with me, if I ask follow up questions or say, “I am not sure how to do that”. However, I am always eager to learn!

First of all, doesnt matter how savvy you are on terminal/ssh as long you type exactly what is mentioned/asked for

#

Which OS do you use?

#

Please show output of ls -l ~/crowsnest

#

If its possible please attach the last full log you can grab

Yep, hold a sec

Ok, I see. You are using MainsailOS 0.7.1

#

So, why did you try to install? Its there by default...

This error says it cant find your USB Cam

Yes, correct. I tired to uninstall using the commands on the github page, but it kept saying dir not empty, could not unistall. so I manually went in a started removing the dir's and files to attempt to get rid of the /crowsnet dir and all the files.

Is there an easy way to remove all crowsnest files/data and install it from scratch to get back to the default state?

sudo rm -f /etc/systemd/system/crowsnest.service
sudo rm -f /etc/logrotate.d/crowsnest

#

In your crowsnest.conf use for the device: section device: /dev/v4l/by-id/usb-046d_HD_Pro_Webcam_C920_AE6F6E5F-video-index0

Should be in klipper_config or printer_data/config/ next to your printer.cfg location

Are you referring to looking for them in mainsail or via ssh?

vernal arrow Jan 10, 2023, 7:14 PM

#

crisp kernel This happends some time, no worries, use ```sudo rm -rf ~/crowsnest```

that seemed to work...no errors. asked me for your PI PW and then returned to the next line.

#

in mainsail, I do not see a crowsnest.config file:

#

I used SSH and looked in both dir, no crowsnest.config file.

crisp kernel Jan 10, 2023, 7:30 PM

#

Only shown 10 entry per page maybe?

#

Poosible you have multiple pages there

#

But, first reinstall, you might have it deleted already

vernal arrow Jan 10, 2023, 7:40 PM

#

I switched it to 100 and still nothing.

#

Run these commands?
git clone https://github.com/mainsail-crew/crowsnest.git
cd ~/crowsnest
sudo make install

ok...we are back..here is what I see:

crisp kernel Jan 10, 2023, 7:47 PM

#

Now you should have the mentioned crowsnest.conf

vernal arrow Jan 10, 2023, 7:47 PM

#

I typed in C920 for the name and saved. Correct..it is there now

#

Is there anything else I need to adjust or modify to keep it working?

#1062401023081193633 message Remember to set this!

section device: /dev/v4l/by-id/usb-046d_HD_Pro_Webcam_C920_AE6F6E5F-video-index0

crisp kernel Jan 10, 2023, 7:48 PM

#

If not /dev/video0 might change on reboots and then your picture disappears

#

Show your crowsnest.conf after change please

vernal arrow Jan 10, 2023, 7:49 PM

#

I will show you the file with the changes, before I save it

#

#

can I increase the resolution here to 1920X1080?

crisp kernel Jan 10, 2023, 7:51 PM

#

There are two space between device: and /dev/... Remove one

vernal arrow Jan 10, 2023, 7:51 PM

#

I did..sorry about that

crisp kernel Jan 10, 2023, 7:52 PM

#

vernal arrow can I increase the resolution here to 1920X1080?

You could try, depends on Pis connection, on ethernet no problem on wifi might function but you have to test

vernal arrow Jan 10, 2023, 7:52 PM

#

Ok..its connected to a Pi 4B on wifi

crisp kernel Jan 10, 2023, 7:53 PM

#

Try it if you get a kind of laggy, dia show it might overwhelm your wifi connection

vernal arrow Jan 10, 2023, 7:53 PM

#

ok..saved the config file restarted and I am back to where I was before, 0 fps in the webcam window with a black screen.

crisp kernel Jan 10, 2023, 7:54 PM

#

check for typos

#

sometimes that x in the resolution gets a wierd x lookalike symbol

#

But have to be lowercase x

vernal arrow Jan 10, 2023, 7:55 PM

#

hmm..ok hold on

#

that was it...I had a X

crisp kernel Jan 10, 2023, 7:56 PM

#

👍

vernal arrow Jan 10, 2023, 7:56 PM

#

going to power it down and turn it back on and check

crisp kernel Jan 10, 2023, 7:56 PM

#

Feel free, but I predict it will work 😉

vernal arrow Jan 10, 2023, 7:56 PM

#

@ 1920x1080, getting about 10fps...might turn it down a bit

crisp kernel Jan 10, 2023, 7:57 PM

#

Yes, that might be a Wifi limitation

vernal arrow Jan 10, 2023, 7:57 PM

#

might try 1080x768?

crisp kernel Jan 10, 2023, 7:57 PM

#

go 1280x720@15FPS

vernal arrow Jan 10, 2023, 7:57 PM

#

ok..will do. booting up now

#

@crisp kernel , you have been amazing!! Thank you for your help today!! I was getting so discouraged.

#

btw, do I need a webcam.txt file?

crisp kernel Jan 10, 2023, 7:58 PM

#

You're welcome mainsail_heart

crisp kernel Jan 10, 2023, 7:59 PM

#

vernal arrow btw, do I need a webcam.txt file?

No, that is deprecated

vernal arrow Jan 10, 2023, 7:59 PM

#

k...i will delete.

#

we are rockin' and rollin'! WOOT

#
