Testers (who own a 3D printer) will be required before we start, please post interest here if you can assist us with testing.

[Yury-MonZon]

Sorry, forgot to reply. I'm in!

[kurtjcu]

Sounds interesting, I have a few printers and pi3/pi2/orangePi to test with, Let me know how i can help. :)

[tobyrobb]

I'm in also , have pi zero w's and a Pi 3 running Diet-pi, and printers.

[Fourdee]

Thanks guys, i'll pop this into v154 and take a look.

Does not run under root, simply terminates with a warning:

Suggestion:

• You should not run OctoPrint as root!
  should be more informative on why the process was terminated, and, cannot be run under root native.
  E: OctoPrint can not be run under root. You can however override this at your own risk with --iknowwhatimdoing

octoprint serve --iknowwhatimdoing

You may need to add the pi user to the dialout group and tty so that the user can access the serial ports:

sudo usermod -a -G tty pi
sudo usermod -a -G dialout pi
from https://github.com/foosel/OctoPrint/wiki/Setup-on-a-Raspberry-Pi-running-Raspbian

Works fine, even autoupdates itself. In our case we could create another user i.e. octo.

Thanks 👍

We dont have a pi user in DietPi. We do have a dietpi user which has same permissions as pi user:
https://github.com/Fourdee/DietPi/blob/4f7f27f49dd2329dc4b8a670896af188d3bf7037/dietpi/func/dietpi-set_software#L171-L197

Although, dietpi user is still under testing, is not implemented as the user for any of our software installations at the moment:
https://github.com/Fourdee/DietPi/issues/896https://github.com/Fourdee/DietPi/issues/896

Root for now, plans to change that in the future :)

[Fourdee]

Available for testing in our testing branch, please see link below for instructions on how to setup an installation with this branch:

@Yury-MonZon @kurtjcu @tobyrobb Would appreciate any assistance with testing this software, please see section above for instructions.

[Yury-MonZon]

Great news! Thanks!
Any plans to add mjpeg-streamer for octoprint? It is much more useful with it included, ie online viewing etc...
Installation details are in the doc I mentioned before.

[kurtjcu]

Awesome. I will have a try with some orange Pi Zero's.

Have been testing on my OrangePi Zero (h2) and is working well. So far only small prints (up to 2 hours) no problem. Interface runs well (including sync layer view for whole print).

I did try to install curaengine to be able to slice on the Zero, however i failed.
I used https://github.com/foosel/OctoPrint/wiki/Cura-Integration as a guide. The first section(use pre compiled file) seemed to be going well until i tried to load a config file. I presumed this was because the verification process was failing due to compiled file not matching my architecture. I tried to follow the make instructions, and made sure I had the 15.06 branch, however make was complaining about no target, and I am afraid that is as far as I got, my compiler Foo is not strong enough for this one...

Things to note:

• python-wxgtk2.8 is not available from repo so I changed to python-wxgtk3.0.
• make sure have cura engine <= 15.06 as octoprint does not support higher versions.

+1 on the capability to stream, I think video is what makes octoprint a complete package.

P.S. Love the project over all, keep up the good work.

[Fourdee]

No joy on mjpg-streamer unfortunately. Won't make it for v154. Although not a solution, we do offer software titles for RPi camera which could be used in tandem:
http://dietpi.com/phpbb/viewtopic.php?f=8&t=5#p48
http://dietpi.com/phpbb/viewtopic.php?f=8&t=5&start=100#p6610

I'll mark this as completed for now. If we get enough requests to add curaengine, i'll create a separate ticket.

[Yury-MonZon]

mjpeg-streamer is working on my orange pi zero with ordinary webcams. It wasn't easy though. What if I'll post my installation logs - will it help? Or it is abandoned completely? Thanks for your work!

[Fourdee]

@Yury-MonZon

What if I'll post my installation logs - will it help?

Worth a shot 👍
Please post them here and we'll test it.

[Yury-MonZon]

I've checked my .bash_history and it looks like I installed mjpeg-streamer-experimantal according to this guide https://github.com/foosel/OctoPrint/wiki/Setup-on-a-Raspberry-Pi-running-Raspbian
without raspicam module - I needed it for ordinary usb webcams (Logitech at the moment).

Please, help me on which files do you need from my system in order to help. I can take the whole system image if you like.

[Fourdee]

@Yury-MonZon

Thanks 👍

mjpeg-streamer-experimantal according to this guide https://github.com/foosel/OctoPrint/wiki/Setup-on-a-Raspberry-Pi-running-Raspbian

Thats fine, i'll check the above and attempt install again.

[Fourdee]

Reopened, attempt: https://github.com/foosel/OctoPrint/wiki/Setup-on-a-Raspberry-Pi-running-Raspbian#webcam

Fails as RASPICAM still has umet deps:

* PLUGIN_INPUT_RASPICAM , Raspberry Pi input camera plugin (unmet dependencies)

Ok, still unable to get this to work for RPi camera module (https://github.com/Fourdee/DietPi/issues/854#issuecomment-317025315). Plan was to automatically install for that device.

For non-RPi camera module cameras, the following should do it:

apt-get install -y build-essential git subversion libjpeg8-dev imagemagick libav-tools cmake
git clone https://github.com/jacksonliam/mjpg-streamer.git --depth=1
cd mjpg-streamer/mjpg-streamer-experimental
export LD_LIBRARY_PATH=.
make -j $(nproc --all)

As we can't get the RPi cam to compile, i'll leave this for now and mark as closed.

[Win-doze]

I don't know if this will help someone but I managed to compile mjpg-streamer for the raspberry pi camera. I came across this webpage https://github.com/AmedeeBulle/octoprint-containers/issues/1 and found if I installed libraspberrypi-dev using 'apt-get install libraspberrypi-dev' before trying to 'make' I got the missing input file and could stream video from the raspberry pi camera.

[MichaIng]

@Win-doze
Thanks for figuring this out

@Fourdee
Worth to give it another try by times?

[Win-doze]

@MichaIng
Still working on it but I have put this into rc.local to get mjpg-streamer to start up on booting my pi zero w:
/root//mjpg-streamer/mjpg-streamer-experimental/mjpg_streamer -o "/usr/local/lib/mjpg-streamer/output_http.so -p 8090 -w ./www" -i "/usr/local/lib/mjpg-streamer/input_raspicam.so -x 1280 -y 720 -fps 15"
and in octoprint used the following:
http://LOCAL.LAN.IP.ADDRESS:8090/?action=stream for stream
http://LOCAL.LAN.IP.ADDRESS:8090/?action=snapshot for snapshot

I am not skilled enough to get it to work using localhost or 127.0.0.1, so if my IP address changes it breaks!
If anyone knows how to do this more elegantly feel free to chip in!

[MichaIng]

@Win-doze
Instead of rc.local, as this runs as a daemon (right) we should create a separate systemd unit that is started by DietPi-Services right before OctoPrint.

Hmm strange that localhost or loopback IP does not work in OctoPrint to access mjpg_streamer. If we don't find a way, we could add a StartExecPre job to the mjpg_streamer systemd unit that updates the IP in OctoPrint settings. But I need to know where exactly this can be done.
But actually the moved docs about this also state to use the loopback address: https://community.octoprint.org/t/setting-up-octoprint-on-a-raspberry-pi-running-raspbian/2337

I will update the topics header to mjpg_streamer feature request.

[soemarko]

I've sort of cobble together a bunch of ideas to solve this for myself. Similar to @Win-doze, I added /root/mjpg-streamer/mjpg-streamer-experimental/mjpg_streamer -i "/root/mjpg-streamer/mjpg-streamer-experimental/input_uvc.so" -o "/root/mjpg-streamer/mjpg-streamer-experimental/output_http.so -p 5001" to rc.local -- let me know where should I put this instead, but this works for now.

For the URL part, I've locked down the ip address from the router side for my pi as it's running pi-hole as well, but I don't even use it, I just use the local name as the url, so for me, the streaming URL is http://printerpi.local:5001/?action=stream (also, I can confirm neither 127.0.0.1 nor localhost works).

Hopefully DietPi will be able to natively support this soon.

[MichaIng]

@soemarko
Thanks for sharing. I think the localhost/127.0.0.1 issue is something we need to forward to mjpg-streamer devs. Did anyone try to access the stream via browser from the Pi itself, using either localhost:5001 or 127.0.0.1:5001? E.g. Chromium should be able to view it.
Perhaps there is some settings switch that disables local access by default, as it is expected to be an overhead to access a stream that is produced by a local camera, via TCP instead of directly or something?
