Hello to who is reading this, I hope you will be able to explain this to me.  I have a printer Ender 2 pretty cool so far!


#Running Rasbian Stretch Installed the OctoPrint server as per instructions;
cd ~
sudo apt-get update sudo apt-get install python-pip python-dev python-setuptools python-virtualenv git libyaml-dev build-essential git clone
https://github.com/foosel/OctoPrint.git cd OctoPrint virtualenv venv
./venv/bin/pip install pip --upgrade
./venv/bin/python setup.py install
mkdir ~/.octoprint
sudo usermod -a -G tty pi
sudo usermod -a -G dialout pi
You should then be able to start the OctoPrint server: pi@raspberrypi ~ $
~/OctoPrint/venv/bin/octoprint serve * Running on
# Works OK so far In my learning curve I also installed OctoPrint directly onto the Pi, seemed more problems to do that.
Also the server app started right up on the first shot the two times I installed it where the other didn't. so I ran with this direction.
# I use the VNC viewer through my Netbook. Hard wired (Local) the Pi and my netbook. Each have wireless connections to the internet through the wifi router. As I was learning this connected through the wifi router (in the beginning) it wasn't stable enough dropping off a lot (Older Router) I wanted guaranteed connection so I enabled my local connection and plugged it in.
arp -a
Wireless>>> Gateway Router
                                   1.149 Pi 1.159 Netbook
                                   1.196 Phone
                                   1.255 Not sure
Local >>>> Netbook connected local to Pi OctoPrint
Server address is      
Time Lapse is located at, (shared to the address)
So the deal is the printer comes with a cat already sliced into the g-code needed to make it. I have made several, and it's pretty cool fun to watch but I have projects I want to make but they are in .stl   The issue is there are no instructions (Clear to follow and understand) as to how to install/use/configure/setup the CURA that is (or isn't) installed in the OctoPrint.  I go to the wrench follow down to the Plugin CURA 15.04 that I believe is installed as I see it there, I can find empty Folders in the file manager under CURA I can find LOTS of information on EVERYTHING BUT using 15.04 in the OctoPrint App. where is the path?  Path to what folder or is it a file? be the path? One instructions was pretty clear, "if file doesn't exist just make it"   well DUH how do you do that? Zip nothing, two weeks cannot find one thread that has simple to follow instructions that give click by click field by field entries that will allow me to use to learn how to slice within the OctoPrint.  I was smart enough to follow the directions to get the Raspberry running, OctoPrint installed and printing, I can read and understand the english language but none of anything I am reading works let alone make sense. Can you help? I'm tired of the CAT  I want to move on and make other things but can't due to lack of understanding or the lack of decent instructions that are to the point, step by step.  Click here, enter this, do next, simple  simple simple and explain what to do if you have to do it, like "just make it" explain how with the description, not have to jump to 5 different subjects to get to to understand "Oh click on that too enter "  thanks in advance, very frustrated so much of a curve to get to do what seems like a simple thing.  Add to all of this (almost forgot) that I did try this>>>

That is what I get and I cannot find any instructions I can follow  PLEASE HELP!!!!!

    Hi @digitheadman , welcome to the community! 

    Hopefully, you'll be able to find some help here to get your Ender 2 printer working, but I think it is good to mention that Ultimaker developed Cura, mainly for Ultimaker 3D printers (and also made it free for others to use). The Ender is not one of our products, nor is Octoprint. We might be able to help with getting you sorted, but if Creality wants its users to be able to use Cura, it is up to them to provide the profile and instructions. We have developed the platform. While reading your post, I had the idea this may not be entirely clear, that's why I mention it. 


    Unfortunately, I don't have the technical knowledge to help, but we have many experts here who do. Good luck!

    Cura and CuraEngine are two different things. CuraEngine is the software that does the actual slicing, Cura is a frontend for it. You can use OctoPrint as a frontend of CuraEngine, as you are trying. Note though that due to a change in architecture, the version of CuraEngine that is compatible with OctoPrint as a frontend is around 3 years old. Also note that slicing is a processor-intensive activity; the raspberry pi is "somewhat" underpowered for the task.


    A better solution would be to use Cura on a "regular" computer, and use the OctoPrint connection plugin to send prints directly to OctoPrint from inside Cura. That way you don't have to compile that old version of CuraEngine.


    If you still want to go the OctoPrint on raspberry pi route, I think you can get more support on http://discourse.octoprint.org/
