By default, no webcam other than the original Nebula can be added to the ender.
I just happened to have an old webcam, so I searched on reedit and found a simple script to fix the operation of other webcams.
- In the ender settings, enable root access.
- In putty connect via ssh to the ender by local IP and the login credentials are displayed in the root tab on the printer.
- type the following commands one by one in the terminal:
cd /etc/init.d
wget http://openk1.org/static/k1/scripts/S50non_creality_webcam
chmod 755 S50non_creality_webcam
/etc/init.d/S50non_creality_webcam restart
