OctoPrint is better than ever - time for an updated install guide!

I have tried latest version on rpi2,i still like repetier host more. …for now
It responses faster,maybe more user friendly,better communication. In my case.
I’m tempted to buy one do run octo on, but part of me still thinks that the Pi Zero will run it in the near future. Ugh can’t decide what to do
Dont wait,buy it now. Zero is to weak to run octo.
The Zero is actually plenty powerful to run OctoPrint (remember, it actually has more grunt than the B+), but you are going to need an additional hub to get any usable amount of USB ports.
Ah right, one USB port… meaning either WiFi or the printer 
Or a hub.
Or get your soldering iron! http://hackaday.com/2015/12/12/solder-more-usb-ports-to-the-raspberry-pi-zero/
@Julien_Dodokal , I’m honestly waiting for the C.H.I.P. – bluetooth/wifi on board already, usb port available, lipo circuitry so I can do cool things like detect power outage and stop print, etc. By the time you add anything to the pi zero, you’re already over the $8 price point, so why not?
@ThantiK It makes sense, but I doubt Octoprint works on it?
@Julien_Dodokal OctoPrint will run on practically any hardware that can run python - and since the C.H.I.P. uses a regular ARM core, it will definitely run OctoPrint. Just not the OctoPi image directly.
@Julien_Dodokal , what Tom said. It runs Linux. It will run OctoPrint. It’s faster than the original raspberry pi which ran octoprint just fine.
Thing is, even if it didn’t have an ARM core – it’s made in Python. I’m sure OctoPrint could run on MIPS, ARM…practically anything that Python could be compiled on as long as it was fast enough.
Right now the C.H.I.P. isn’t available to end users, only kernel developers. But should be available soon. Honestly I can’t wait.
@ThantiK I preordered 2 during their $8 special. Looks like I’m not getting it until spring or summer though. Let me know if you make any progress with it.
@raykholo Mine is supposed to be here early 2016.
You can hook up the printer to the UART on the Pis GPIO rather than going through USB (it’s only a USB to UART adapter on the printer board anyway). I’ve used it like this for years now without problem.
But honestly the speed difference for the Pi2 is worth the few quid.
@Thomas_Sanladerer what’s the black board behind the Pi2 there?
I’m running Octoprint on a QNAP NAS, works as a charm.
@Liam_Jackson the two black boards are the Beaglsbone Black and the LeMaker Guitar ( http://wiki.lemaker.org/LeMaker_Guitar ) - review coming soon!
@Thomas_Sanladerer ah from the banana guys! Looks interesting, I like the idea of shoving that SOM onto a print board. If they can hit the $25 point. SOMs don’t tend to be as cheap as SBCs these days!
