Octoprint (3D print server) on Omega2+
İNDEX OF/CONSOLE ERROR
When I make 192.168.3.1 it gives this error and it is not an IP conflict problem. Why do I get this error? How do we fix it? I'm waiting for your help
@ayhan-uçar Stop spamming in every single thread you can find, you twat
@Jason-Allred I did forget to add the
opkg install python-devpart. I'll run through everything else I did on a clean system to figure out what else I missed. I will point out that netifaces is where the hangup was. Whatever I am missing here got it to install.
@Jason-Allred Try running
pip install --upgrade setuptoolsthen netifaces should work.
@Jeff-Karney Also having troubles with netifaces installing (for Octoprint 1.3.1), all versions 0.10.X wont install (thought i would try it out), followed all the steps mentioned in this post. What firmware are you using on the omega 2+?
Im currently running b160. If your interested the output from pip is http://pastebin.com/pCyhgxpP it looks like python cant find the compiler as its missing the cache_cc directory. Did you set any environment variables to point to the GCC compiler?
Is it ok if I power my omega2+ via the USB A port? In other words, it's getting its power form the 3D printer's USB connection. It's working just fine, I'm just wondering if I am setting myself up for problems later on. It certainly makes for a cleaner install.
I originally had it powered via the microUSB from my laptop but then I went to power the omega2+ from a USB power adapter plugged into the power bar. I noticed that when I unplugged the microUSB power cable, it stayed on.
My printer is the Kodama Trinus3D which is running a proprietary variant of Marlin (I think).
@Jason-Taylor: It seems you have a non-standard USB port on your 3D printer. Usually an USB client port does not feed back power to the host. Assuming your 3d printer can provide enough current, you can totally run you Omega2 off the printer power without an extra power supply.
@Jeff-Karney Like @Ben-Murphy from a month ago, I'm having issues installing OctoPrint 1.3.1 - first when doing the
pip install --upgrade setuptools, and then when when running
pip install netifaces. I've just updated to b160, on an Omega2+. Any ideas as to what's going wrong?
@Jason-Taylor I have finally soldered up an adapter board so I can use my Omega2+ as a OctoPrint server, and since the Omega2+ consumes around 180-250ma, and the Kodama Trinus is a bit naught and backfeeds down the USB line (have they not heard of a diode?), I decided to have it power from the Trinus's USB, since I was connecting to it to control the printer. Seems to be coping just fine! Now I just have to work out how to upgrade OctoPrint, as I'm current stuck with the v1.0.0 as the alternate instructions for 1.3.1 didn't work for me.
I also have the problem with netifaces installing OctoPrint 1.3.1or OctoPrint 1.3.2.
There's a solution?
This post is deleted!
See if this fixes the compile problem.
ln -s /usr/bin/gcc /usr/bin/ccache_cc
This is amazing!! Can't wait to try it out!
@Alan-Brand Well, I ran that command, but I'm not sure yet. I was initally getting out of memory errors, so I added a 256MB swap file, and then kept going, and now I'm getting a "IOError: [Errno 28] No space left on device"??? Hello... there's only 13.3G of free space on the micoSD? :-O :gun:
Edit: Monkey behind the keyboard then realises that he had stupidly and willfully skipped instructions from earlier, and said error message was a result of not enough space in /tmp. Error message could have pointed that out though! :-O
Later Edit: I can now confirm that after a) adding some swap memory b) following the instructions properly and possibly c) doing the
ln -s /usr/bin/gcc /usr/bin/ccache_ccsuggested by @Alan-Brand that I have OctoPrint 1.3.1 installed and running. I see 1.3.2 is now out and about, but I haven't tried it out just yet. ;)
Even Later Edit: Ok, decided to download and roll out OctoPrint 1.3.2 since I'm fiddling around with stuff. Configured without a hickup, and is now running happily. Instead of the root user patch, you are better off using the bypass option that is present now in OctoPrint... so instead of adding
/etc/rc.localyou want to add
octoprint serve --iknowwhatimdoing &The same would apply to 1.3.1, and as far back as whenever that option was introduced.

I gave up using o2+ for octoprint.
A person at a local hackerspace ported octoprint to another board he is testing which has a mega and a chip running some sort of lede. His github is here
Maybe there is something you guys can also use for the O2+, I am going to see if I can get one of these boards and make my life easier.
I am able to run 1.3.4.
mount -o remount,size=200M /tmp ==> To increase /tmp
ln -s /usr/bin/gcc /usr/bin/ccache_cc ==> to install
sed -i 's/Häußge/H./g' /root/OctoPrint-1.3.4/src/octoprint/util/comm.py
sed -i 's/exit("You should not run OctoPrint as root!")/pass/g' /root/OctoPrint-1.3.4/src/octoprint/server/init.py
Also, swap I did it in USB. Creating a swap file in SD card (ext4 format) was not working for me.
I seem to be having a memory issue on the "pip install -r requirements.txt" step.
ANy ideas how to combat this?
Got 1.3.5 to run, together with Cura.
There are quite some hacks, but hope this is useful for you. Start from the comment of Jeff Karney (11 Mar 2017) - and do create the swap file of 512MB !
Continue Octoprint Installation
Replace step 3 with the following steps...
cd /root wget https://github.com/foosel/OctoPrint/archive/1.3.5.zip unzip 1.3.5.zip
Make sure everything can compile
ln -s /usr/bin/gcc /usr/bin/ccache_cc
Install all dependencies
cd OctoPrint-1.3.5 pip install -r requirements.txt
Fix unicode we can't deal with in the code
sed -i 's/Häußge/H\./g' /root/OctoPrint-1.3.5/src/octoprint/util/comm.py sed -i 's/Häußge/H\./g' /root/OctoPrint-1.3.5/src/octoprint/plugins/virtual_printer/virtual.py
Start octoprint from command line (see article on how to auto-restart it on boot)
octoprint serve --iknowwhatimdoing &
opkg install make
Download Cura legacy
cd /root wget https://github.com/Ultimaker/CuraEngine/archive/legacy.zip unzip legacy.zip
Here's a hack I found-out I needed since make failed (forgot how)
echo "#undef LIBC_HAS_BACKTRACE_FUNC" > /usr/include/execinfo.h
Then we can build Cura (it's long on the Omega2+)
cd CuraEngine-legacy make
For some reason ld can't find the static libraries for c and stdc++ and the build fails. I couldn't fix this directly, but what I did was to remove the
--staticfrom the last build line and this works.
so if your build fails with:
/usr/bin/ld: cannot find -lstdc++ /usr/bin/ld: cannot find -lc collect2: error: ld returned 1 exit status
then run this (or remove the
--staticfrom the last output of make):
g++ build/bridge.o build/comb.o build/gcodeExport.o build/infill.o build/inset.o build /layerPart.o build/main.o build/optimizedModel.o build/pathOrderOptimizer.o build/polygonOptimizer.o build/raft.o build/set tings.o build/skin.o build/skirt.o build/slicer.o build/support.o build/timeEstimate.o build/modelFile/modelFile.o build/ut ils/gettime.o build/utils/logoutput.o build/utils/socket.o -o build/CuraEngine -Lbuild/ -lclipper -flto
Give Octoprint the path to Cura
Run the Octoprint wizard: open
http://omega-xxxx.local:5000where xxxx are the 4 last digits of your Omega2+ mac address
In the Cura Configuration step input the Octoprint setup Wizard CuraEngine:
Path to CuraEngine:
However, I can't seem to connect to the 3d Printer. I've tried all the manual settings and baud rates but I get a 'Timeout while trying to connect to the printer' message.

I know the last reply to this topic is from nearly a year ago, but just wanted to report that I just installed OctoPrint v1.3.9 on my Omega2+ with the latest 0.2.1 (b199) firmware (had 0.2 or the last of the 0.1 line and OctoPrint 1.0.0 when I used it last), and it seems to be working fine with my Kodama Trinus printer just fine... Thanks to all the posters who suggested the swap memory, python-dev/gcc and octoprint serve --iknowwhatimdoing workarounds / updates to the instructions... after some fumbling around I was able get it all working! ;)
