Octoprint (3D print server) on Omega2+

  • P

    @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?

    See if this fixes the compile problem.
    ln -s /usr/bin/gcc /usr/bin/ccache_cc

    @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? 😮 🔫

    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! 😮

    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?

    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 &

    Install Cura

    Install prerequisites

    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 --static from 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 --static from 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:5000 where 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: /root/CuraEngine-legacy/build/CuraEngine

    @Theodore-Marescaux and @Jeff-Karney - thanks so much for the updated script. I've got Octoprint 1.3.5 working on my Omega 2+.

    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.

    ----- Terminal Log -----
    Connecting to: /dev/ttyACM0
    Changing monitoring state from 'Offline' to 'Opening serial port'
    Connected to: Serial<id=0x232abc0, open=True>(port='/dev/ttyACM0', baudrate=115200, bytesize=8, parity='N', stopbits=1, timeout=10.0, xonxoff=False, rtscts=False, dsrdtr=False), starting monitor
    Changing monitoring state from 'Opening serial port' to 'Connecting'
    Send: N0 M110 N0*125
    Recv: ?
    There was a timeout while trying to connect to the printer
    Changing monitoring state from 'Connecting' to 'Offline'
    Connection closed, closing down monitor

    ----- Close Terminal Log -----

    Any ideas?

    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! 😉

    First thank all contributor

    1.Change the package repository

    vi /etc/opkg/distfeeds.conf

    uncomment below line

    src/gz reboot_base
src/gz reboot_packages

    2.Setting SD Card As a expanding storage ( I use 2GB mini SDcard , Because out of space error)

    opkg update
opkg install fdisk e2fsprogs block-mount

    after install

    umount /dev/mmcblk0p1
mkfs.ext4 /dev/mmcblk0p1
umount /dev/mmcblk0p1
mkdir /mnt/SD
mount /dev/mmcblk0p1 /mnt/SD

    (will get some error like : can’t umount just ignore it)

    tar -C /overlay -cvf - . | tar -C /mnt/SD/ -xf - 
umount /mnt/SD

block detect > /etc/config/fstab

    Auto Load on system boot

    vi /etc/config/fstab

    change option target '/mnt/mmcblk0p1' to option target '/overlay'
    and option enabled '0' to option enabled ‘1'

    reboot

    after reboot you can verify if you /overlay is mounted properly by running df

    mkdir /overlay/tmp
rm -rf /overlay/tmp/*
cp -a /tmp/* /overlay/tmp/
umount /tmp
[ $? -ne 0 ] && {
umount -l /tmp
}
mount /overlay/tmp/ /tmp

    after reboot expand /tmp folder on the Omega , will get some error like : can’t umount just ignore it)

    3.Install C++ Lib & Python

    opkg update
opkg install gcc make 
opkg install python python-pip unzip
opkg install python-dev --force-overwrite

    4.Setting Swap memory (Because When install will get out of memory errors)

    https://docs.onion.io/omega2-docs/extending-omega-memory.html

    First insert your usbdisk

    opkg install swap-utils

    after install create swapfile on usb

    dd if=/dev/zero of=/tmp/mounts/USB-A1/swap.page bs=1M count=512

    Need Waiting a while

    mkswap /tmp/mounts/USB-A1/swap.page
swapon /tmp/mounts/USB-A1/swap.page

    Use free to check if success get swap

    5. Install Octoprint

    pip install --upgrade setuptools

    show some information to upgrade pip

    pip install --upgrade pip
pip install --upgrade setuptools

    Download octoprint & install
    You can get all version here
    https://github.com/foosel/OctoPrint/releases

    Prepare Install

    cd /root
wget https://github.com/foosel/OctoPrint/archive/1.3.9.zip
unzip 1.3.9.zip
cd OctoPrint-1.3.9

ln -s /usr/bin/gcc /usr/bin/ccache_cc

    Start Install

    pip install -r requirements.txt

    Some Unicode Fixed / User Role Fixed

    sed -i 's/Häußge/H\./g' /root/OctoPrint-1.3.9/src/octoprint/util/comm.py
sed -i 's/Häußge/H\./g' /root/OctoPrint-1.3.9/src/octoprint/util/virtual.py
sed -i 's/Häußge/H\./g' /root/OctoPrint-1.3.9/src/octoprint/plugins/virtual_printer/virtual.py

sed -i 's/exit("You should not run OctoPrint as root!")/pass/g' /root/OctoPrint-1.3.9/src/octoprint/server/__init__.py

    If has no error.
    Congratulation !
    Almost Success!

    6.Server Start

    octoprint serve --iknowwhatimdoing &

    Need Waiting Server to Start / console will show some infor & some warning information / Just Ignore
    Use browser to connect
    http://omega-[your id].local:5000

    If connect Ok.
    Now You can remove usb disk and connect to 3d printer.
    Success!!

    Print the case
    https://www.thingiverse.com/thing:2068124!

    Sometimes Factory Reset Clean All to Install Will Help , if you get some stange error

    https://docs.onion.io/omega2-docs/factory-reset.html

    I got Octoprint 1.5.1 to work with my Omega2+. Instructions are basically the same as @Ming-Chou-Cheng wrote, but I had to change some minor things. I'll post details if anyone is interested, let me know.
