I've been spending some time modding my Prusa i3 MK2 3D printer before I get into some heavy printing.
My latest modification is installing a Raspberry Pi 3 powered OctoPrint. I also got a endoscope (usb 2.0 camera) mod so that I can view and record my prints.
I am using a Raspberry Pi 3 as the brain, flashed with Octoprint Version: 1.3.1 (master branch).
The camera above shows up as 1e4e:0110 Cubeternet. To get it to work you need to edit /boot/octopi.txt and add camera_usb_options="-r VGA -f 10 -y" to get the camera working. Once you make this change you need to reboot your Pi. I have confirmed this to work with the USB camera above.
For the Raspberry Pi mount, I only printed the back place as I need full access to the GPIO inputs and I don't want to be taking the front cover off all the time. There are covers with the GPIO pins exposed but I prefer it this way.
I also made sure my debian distro is up to date using using apt-get update && upgrade.
Once I get through a few prints I will post the recording of the endoscope camera.
