OctoPrint is an open-source 3D printing server that allows users to manage and control their 3D printers remotely. It is widely popular among 3D printing enthusiasts for its powerful features and ease of use. The OctoPrint team is constantly working on improving the software, which means that new updates are released frequently. In this article, we will learn about updating OctoPrint and some code examples for customizing it to our needs.
Updating OctoPrint
The process of updating OctoPrint is relatively simple. The following steps will help you update OctoPrint to its latest version:
Step 1: SSH into your Raspberry Pi using a terminal (e.g. PuTTY). Enter your login credentials and navigate to your OctoPrint installation directory.
Step 2: Enter the following command to download the latest version of OctoPrint:
wget https://github.com/foosel/OctoPrint/archive/master.zip
Step 3: Unzip the downloaded file using the following command:
unzip master.zip
Step 4: Now, remove the old installation by running the following command:
rm -rf OctoPrint-<version>
Replace "version" with the version number of your current OctoPrint installation.
Step 5: Copy the new installation files to the installation directory using the following command:
cp -r OctoPrint-master/* ./
Step 6: Run the following command to upgrade any dependencies that come with OctoPrint:
~/oprint/bin/pip install --upgrade -r requirements.txt
Step 7: Finally, restart OctoPrint using the following command:
sudo service octoprint restart
And that's it! Your OctoPrint installation is now updated to the latest version.
Customizing OctoPrint with Code Examples
OctoPrint is highly customizable, and the best part is that you can achieve this by writing your own plugins and adding them to the OctoPrint instance.
For example, let's say you want to customize the look of the OctoPrint web interface. You can achieve this by creating a custom CSS file and linking it to OctoPrint. Here's an example of how you can do this:
Step 1: Create a new file named custom.css in the /home/pi/.octoprint/static/css/ directory.
Step 2: Add the following CSS code to the custom.css file:
/* Custom styles for OctoPrint */
body {
background-color: #333;
color: #fff;
}
h1 {
font-size: 24px;
font-family: 'Arial', sans-serif;
}
.btn-primary {
background-color: #28a745;
color: #fff;
border-color: #28a745;
}
.btn-danger {
background-color: #dc3545;
color: #fff;
border-color: #dc3545;
}
This code will change the background color of the page to #333, the font size of all the h1 tags to 24px, and change the primary and danger button colors.
Step 3: Link the custom.css file to OctoPrint by editing the /home/pi/.octoprint/config.yaml file and adding the following code:
appearance:
custom_css:
- /static/css/custom.css
This code links the custom.css file to OctoPrint and specifies its location.
Step 4: Restart OctoPrint by running the following command:
sudo service octoprint restart
Now, when you access the OctoPrint web interface, you should see the changes you made reflected in the UI.
Conclusion
OctoPrint is a fantastic tool for managing and controlling 3D printers remotely. Updating OctoPrint is a straightforward process that ensures that you have the latest features and bug fixes. Customizing OctoPrint is also a simple process, and you can achieve a lot by writing your own plugins and adding them to the OctoPrint instance. With this article, you should now have a good understanding of how to update OctoPrint and customize it to your needs.
