OctoPrint webpage freezes (Setup on a Raspberry Pi running Raspbian)

  • I have been using a software called OctoPrint that allows you to control your printer in your Browser. For sake of simplicity I have used Octopi, a preinstalled image with OctoPrint, but now I would like to make some changes, and I decided to build OctroPrint by myself, the instructions for building it are here: https://github.com/foosel/OctoPrint/wiki/Setup-on-a-Raspberry-Pi-running-Raspbian. The problem is that when I follow the first commands:

    sudo apt-get update
    sudo apt-get upgrade
    cd ~
    sudo apt-get install python-pip python-dev python-setuptools python-virtualenv git libyaml-dev build-essential
    git clone https://github.com/foosel/OctoPrint.git
    cd OctoPrint
    virtualenv venv
    ./venv/bin/pip install pip --upgrade
    ./venv/bin/python setup.py install
    mkdir ~/.octoprint
    sudo usermod -a -G tty pi
    sudo usermod -a -G dialout pi

    And then I start the octoprint server


    The webpage of Octoprint freezes

    enter image description here

    I don't know if this is fixed in later commands, but I would like to get a sense of how all fits together before continue. It doesn't look that is the browser (I am capable to visit other websites without any problems), so is maybe Octoprint? How can I fix this? Did anyone have this problem before? Thanks in advance

    The output in the console is:

    Do any errors pop up in the console? Press F12 and go to a console tab/menu, paste any errors you see. There might be an issue connecting to a machine. Do you have the machine turned on?

    I just added the output in the console. The raspberry pi is turned on. Also I forgot to say that the website is fine when is loading, but after 3 or 4 seconds, it freezes

    1. You mentioned you started with the stock OctoPI build/installation but didn't mention that everything works without your changes. 2. Have you tried making your improvements one at a time to find out where the freezing web-page is introduced?

    I am not making any improvements yet. I am just following the steps of https://github.com/foosel/OctoPrint/wiki/Setup-on-a-Raspberry-Pi-running-Raspbian, and I am stuck in that step

  • Is it the Raspberry Pi that locks up, or just the webpage? If the whole thing becomes unresponsive I would consider reviewing your overclocking settings. If you've set one of the higher overclocking values in the config script, this can often lead to random lockups. If you don't see the config script every time you boot the Pi, you can access it by typing the following into a terminal window.

    sudo raspi-config

    You can find out how to change the overclocking settings from the config script in this guide
