Using a Raspberry Pi + Octopi to manage your printer

The image should appear on the Control tab.

In Chrome, try "http://octopi.local"

Chrome can be very aggressive about searching instead of visiting local network sites.

Any idea why the video works in safari but not chrome? when I use the IP that is.

Also the video is delayed about 4 seconds and seems chopy, is this normal? is it because I am using a usb camera and if I used the pi cam it would be much more fluid since that uses a different data bus? Is it that the default is 10 fps? Do folks up that?

Your video should be pretty smooth if viewing from inside the LAN, but across the internet I have found it is very choppy and lags quite a bit behind the actual print. I haven't found a cure for the laggy performance across the internet when connecting directly to the Pi, but if you remote into a local computer to the Pi (from the internet) and connect to the Pi from there it is smooth and immediate. I have also changed the frame rate to 20fps from the default 10fps although it was quite smooth at 10fps. You can edit video resolution and fps (either USB camera or a Pi cam) in the /boot/octopi.txt file.

Remoting into a local computer to connect to the Pi also solves my problem of allowing protected access to print viewing for me since I can control username and password to the remotes easily. I'm using virtual machines through Hyper-V and my 2012 server and have 3 virtual Win 8.1 machines setup for this so I can allow multiple viewing access at once. I have them setup so when logging into the VMs it has restricted access to the VM and opens Chrome and logs into the Pi automatically so my friends just enter a username and password at the login screen and OctoPrint starts immediately. And even with 3 logged in it is very smooth video.

BTW, you don't need a server for this. If you have a Win8 machine at home you can have Hyper-V and one VM running concurrent with your console session. It's a free addon to Windows 8 and 8.1 (but you will need a license for the virtual machine OS... but you can use the Win 8.1 Enterprise evaluation for 120 days for free or use the Windows 10 technical preview for free if you prefer). So with Windows 8 Hyper-V you can have 2 people using the Win8 machine at the same time.

The difference with the video streaming is night and day when logged in from a LAN source rather than across the internet, even though you are remoting into a computer from the internet. Maybe there is a way to get the Pi server to handle internet connections better and I just haven't found it yet. But this makes a big difference for me.
