Add a usb webcam, pi camera, or camera to your 3d printer! Watch and monitor your 3d printer from the comfort of your couch! Adding the ability to view your 3d printer live can bring your setup to another level. In this video we use Crows Nest to handle all of the camera operations. This installation requires Klipper firmware and a front end choice of either Fluidd or Mainsail.

Commands:

Install Crows Nest from the terminal line of your Klipper host device(paste this as a single block of commands)-

cd ~
git clone https://github.com/mainsail-crew/crow...
cd ~/crowsnest
sudo make install

Reboot the mcu (if you didn’t have Crows Nest perform it for you) -

sudo reboot -f

crowsnest.conf file path variations for Klipper/moonraker (Edit file: ~/printer_data/systemd/crowsnest.env)-

Single instance/old moonraker-
~/klipper_config/crowsnest.conf

Multi instance/old moonraker-
~/klipper_config/printer1/crowsnest.conf

Multi instance/new moonraker-
~/printer_1_data/config/crowsnest.conf

crowsnest.conf log path variation(make edit to log path in crowsnest.conf)-

Old Klipper/moonraker(multi and single instance):
~/klipper_logs/crowsnest.log

Updated Klipper/moonraker(multi instance):
~/printer_1_data/logs/crowsnest.log

Find device id for camera (try this one first)-
ls -l /dev/v4l/by-id

Find device id for cameras returning the same address(ties address to USB port. If the camera changes port you will need to find the new address)-
ls -l /dev/v4l/by-path

*additional info: I wanted to add a few extra pieces of information that user Jeffrey Griffis provided.
for those multi instance users who NAMED their profile instances in KIAUH (i.e if you chose to give the instance a specific name while installing, not the name you give it on your front end). Then your folders will not be called "printer_data_1" and instead be called the specific name you chose and then the instance number "_1" "_2" and so on.

also when naming your camera you may only give it a single word name. "cam logiPro" is fine, but "cam logi Pro" is not. underscores can(and should) be used to connect multiple words together as a single word. (ie. cam logi_pro_ender_3)
