I have just switched from crowsnest to spyglass and when I run the script I get the above. Help is much appreciated. I'm trying to get my pi cam v3 wide to work on my printer

[B1ueOne]

Solved after reinstalling crowsnest and uninstalling it by hand. However, a new issue arose:

Stop crowsnest.

Failed to acquire camera: Device or resource busy

That means the cam is currently used by a different service. I'm wondering, why you swapped from crowsnest to spyglass.

[B1ueOne]

Stop crowsnest.

Failed to acquire camera: Device or resource busy

That means the cam is currently used by a different service. I'm wondering, why you swapped from crowsnest to spyglass.

Because I can't get my pi cam v3 to work with crowsnest, no matter what I try

[mryel00]

RuntimeError: Failed to start camera: Input/output error

This indicates that you ase using a touchscreen and a cam. Those won't work well together. This issue should be fixed for some instances on Bookworm.

[mryel00]

Because I can't get my pi cam v3 to work with crowsnest, no matter what I try

This won't be different with spyglass then, as you already saw with the new issue.

[B1ueOne]

I've uninstalled KlipperScreen and Crowsnest completely, however I'm still getting the same errors.

Either it's RuntimeError: Failed to start camera: Input/output error if I have dtoverlay=vc4-fkms-v3d or it changes to Failed to acquire camera: Device or resource busy when I have dtoverlay=vc4-kms-v3d

[mryel00]

Disconnect the screen. Changing the mentioned dtoverlay will most likely activate and deactivate touch and rotation of the screen. No idea why you get the resource busy, but it's like I said, it signals that something else is using the cam. Maybe you got the spyglass service installed?

[B1ueOne]

I physically disconnected the screen as you suggested, no change sadly.

I installed spyglass as described with:

cd ~/spyglass
make install

and added the following to my moonraker.conf:

[update_manager spyglass]
type: git_repo
channel: beta
path: ~/spyglass
origin: https://github.com/roamingthings/spyglass.git
managed_services: spyglass

Not sure what I could have done wrong here

[mryel00]

Just to be sure run the following commands and get me the output of each one.

sudo systemctl stop crowsnest
sudo systemctl disable crowsnest
sudo systemctl stop spyglass
~/spyglass/run.py

Also send your `/boot/config.txt

Delete the last two lines from your /boot/config.txt. The run command shows that it's working as intended, so start the spyglass service again with sudo systemctl start spyglass. Then edit the spyglass.conf in your webui to either use the default urls of your UI or use the default urls of spyglass to add them in the UI, as described here

[B1ueOne]

I added the Webcam to the UI as described, however I only get a blank, white image

/webcam/?action=stream
/webcam/?action=snapshot
MJPEG-Streamer

[mryel00]

There is a typo in your stream url

[B1ueOne]

It doesn't work either with

/?action=stream /?action=snapshot

if that is what you mean

[mryel00]

#### Stream URL (STRING)[default: /stream]
STREAM_URL="/?action=stream
#### NOTE: use format as shown below to stay MJPG-Streamer URL compatible
## STREAM_URL="/?action=stream"

There is a typo in your config. There is a missing "

[B1ueOne]

Ah. Fixed it. However, I'm afraid it still only shows a blank white image. At this point I just want the camera to work any way possible. I've been at it all day trying to troubleshoot.

[B1ueOne]

The run command shows that it's working as intended, so start the spyglass service again with sudo systemctl start spyglass.

Are you sure? I still had errors in the text I've posted above:
