Setting up OctoPrint on a Raspberry Pi running Raspbian or Raspberry Pi OS

https://docs.octoprint.org/en/master/configuration/config_yaml.html

@user8374585 Works great, thanks for that.

I've followed the tutorial and when I run the serve command this is the last I see:

I'm assuming it's supposed to be running, but when I go to 127.0.0.1:5000 or http://raspberrypi:5000/ the browser just keeps loading forever and nothing happens.

Updated 2020-11-03 to use Python 3 instead of 2 for installation.

shouldn't this be
python3 -m venv venv
to properly use python 3 instead of defaulting back to python 2?

You are right, I thought I'd added the --python=python3 to it, but yes by default that will create the venv using Py2. Will have to test it later today, to make sure there are no extra dependency steps etc.

Post has been updated to address this issue, now uses venv

Having done an absolute **** tonne of research and work on this, I finally got the correct info to get RPi_Cam_Web_Interface working with Octoprint :smiley:

Install settings for RPi_Cam_Web_Interface:

Cam subfolder: html
Autostart: yes
Server: nginx
Webport: 8080
User: Your username here
Password: your password here
jpglink: yes
php: 7.3

Webcam settings for Octoprint:

Stream url: http://your ip here/html/cam_pic_new.php
Snapshot url: http://your ip here/html/cam.jpg
Path to FFMPEG: /usr/bin/ffmpeg

The main benefit of this is being able to have security on the camera feed.

I've not actually done a build yet to test these (still building my printer) but if someone could test? Everything looks fine from Octoprint settings but the proof is in the pudding so to speak.

So stumbled across this in a forum.
Alot cooler than i thought.

Wondering if anyones used it in ubuntu or on android os?

I have an older UDOO board i would like to apply to my workspace. Has lvds and camera support.

Ubuntu is easy, pretty much just substitute the user pi for whatever you setup on ubuntu. Can't commend on android OS.

Hi.
I've installed OctoPrint on Raspbian OS Desktop and all seems to work fine, but when I go to Pluguin manager says:

The pip command could not be found or does not work correctly for this installation of OctoPrint - please consult the log file for details and if necessary configure it manually. No installation and uninstallation of plugin packages is possible while pip is unavailable.

I've checked python2 and python3 and both have pip installed. Any idea?

PS: I want to say thanks who updated this installation guide.

Are there any details to be found here? Please upload the octoprint.log.

Here you have..

I fixed the problem as I seen the log.

I'm setting this up on a debian linux laptop, so I'm not using a Pi. I'm providing this info for others if they run into this issue.

I had issues with the haproxy configuration since things apparently change after a certain version. I'm running version 2.2.9-1

While this probably doesn't affect the Pi, it might eventually.

I got these warnings and errors:

[WARNING] 051/085546 (3107) : unexpected character 'i' after the timer value '15min', only (us=microseconds,ms=milliseconds,s=seconds,m=minutes,h=hours,d=days) are supported. This will be reported as an error in next versions.

I fixed it by changing the haproxy.cfg to:

global
        maxconn 4096
        user haproxy
        group haproxy
        daemon
        log 127.0.0.1 local0 debug

defaults
        log     global
        mode    http

        option  dontlognull
        retries 3
        option redispatch
        option http-server-close
        option forwardfor
        maxconn 2000
        timeout connect 5s
        timeout client  15m
        timeout server  15m

        bind :::80 v4v6
        use_backend webcam if { path_beg /webcam/ }
        default_backend octoprint

backend octoprint

        option forwardfor
        server octoprint1 127.0.0.1:5000

backend webcam
        http-request replace-path /webcam/(.*) /\1
        server webcam1  127.0.0.1:8080

I found these changes at Making OctoPi build on Ubuntu 64bit so we have 64bit builds · Issue #711 · guysoft/OctoPi · GitHub

I have installed OctoPrint according to the guide at the top of this page and everything appeared to go without any errors or warnings. I setup autostart according to the guide and the service starts on bootup and can be restarted, stopped and started by the appropriate commands. The only problem is when opening the web interface I get nothing. No feedback no nothing. It just times out. I have been using OctoPrint for 4 or 5 years and always installed from the octopi image. This time I did not want to erase my pi. The browser I am using is running another instance of OctoPrint on a seperate rPi. I am using winSCP and Putty to investigate as these are headless

The command "ps -ef | grep -i octoprint | grep -i python" returns:
pi 1966 101 4.3 144592 38796 ? Ssl 15:56 0:04 /home/pi/OctoPrint/venv/bin/python3 /home/pi/OctoPrint/venv/bin/octoprint
pi 1981 0.0 1.7 22644 15344 ? R 15:56 0:00 /home/pi/OctoPrint/venv/bin/python3 -m pip --version
The command "curl -D - localhost:5000" puts out more than 100 pages of HTML.

Hopefully someone may take a look at this info and be able to help an old man out. Thanks for any insight provided.
