Logitech c920

I have my C920 on the printer and the autofocus is drivin me crazy. Is there a way to dissable autofocus on klipper, mainsail?...

You could try to add custom flags ins crowsnest.conf
custom_flags:
I don't remeber exactly how but I managed to set a fixed focus for my c920 in this way. Maybe you can find more details on the web
Anyhow, this cam didnt work for me since I've got only kinda 3 or 5 FPS from it, so I switched camera model

for what its worth @argusz

my c920 crowsnest.conf looks like :

#### crowsnest.conf
#### This is the default config after installation.
#### It is also used as the default config in MainsailOS.
#### For details on how to configure this to your needs, see:
#### https://github.com/mainsail-crew/crowsnest/blob/master/README.md

the v4l2ctl section is what you change, after you do that, either restart crowsnest, or your host/pi because sometimes it needs to reload everything.

Thank You. Mine endet up looking like this:

v4l2ctl: focus_automatic_continuous=0,focus_absolute=0

and it works ok. Now the autofocus is not longer jumping all around.....
