Octoprint (3D print server) on Omega2+

ErBussola

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 Mond

This is amazing!! Can't wait to try it out!

Peter Feerick

@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.

Mitchell Reiff

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?

Theodore Marescaux

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!

Ming Chou Cheng

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
