Octoprint (3D print server) on Omega2+



  • Tried installing 1.3.1 with cache & gcc. Got stock on a netifaces error. Either upgrading pip or installing python-dev seemed to get past that.

    pip install --upgrade pip
    opkg install python-dev --force-overwrite
    pip install netifaces



  • 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-dev part. 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 setuptools then 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.



  • Hi,
    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_cc suggested 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 octoprint & to /etc/rc.local you 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

    https://github.com/robinjanssens/OctoPrint-for-MiCaBoard

    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.
    https://pastebin.com/xS4i0a2C
    ANy ideas how to combat this?
