Many enthusiasts use Octoprint as their preferred 3D printer controller, and for good reason. With the help of an open-source web interface and OctoPi software, 3D printers can now have intelligent capabilities without having to upgrade their hardware. Octoprint allows users to update the firmware of their 3D printer, view a webcam feed, start printing tasks, and remotely check the temperature of their machine.
The fact that Octoprint works with a wide range of popular 3D printer brands is one of the main reasons aficionados adore it. It's not limited to a PC either. It can be installed on Linux or Windows, but it can also be run on a small device like a Raspberry Pi. For the software, Octoprint suggests using Raspberry Pi 3B, 3B+, 4B, or Zero 2 hardware. Using Raspberry Pi Zero and Zero W is discouraged.
An SD card that can serve as the boot disc is required in order to install OctoPi on a Raspberry Pi. This implies that an external reader or a PC with an SD card slot are required. However, take note that backing up your data is advised since installing OctoPi on an SD card will erase everything from the device.
Installation Process
Via the Raspberry Pi Imager, the OctoPi is installed. This software, which is available on the Raspberry Pi website, enables users to install the official operating system.
Use these procedures to install the OS's OctoPi branch:
- Insert the SD card you want to use for the project.
- Open Raspberry Pi Imager.
- Under Operating System, click Choose OS.
- Scroll down and select the Other Specific-Purpose OS option.
- Click 3D Printing.
- Select OctoPi from the list of options.
- Click OctoPi Stable.
- Back in the main Raspberry Pi menu, click the Choose Storage option.
- Select the SD card you want to install OctoPi on.
There are a few parameters you may wish to change before starting the writing process. Click the cog icon located in the lower right corner of the Raspberry Pi Imager window to access these settings. From here, you may configure a username and password, enable SSH, and set the hostname of the device. You must provide the password and SSID for your connection on this page in order to setup a wireless LAN connection.
First Time Setup
The Octoprint browser menu can be accessed in several ways. Entering the hostname you entered during installation into your browser's address bar is the simplest method. However, this requires Bonjour to be supported on your PC. Additionally, you can use http://octopi.local and http://( the IP address of your Pi ).
- When you access Octoprint for the first time, you will be greeted with a setup wizard.
- The first page will give you a box to input the system's username and password. Setting this up keeps the printer from being used by other individuals on your network freely.
- On the next page, click Test Host & Port and Test Name Resolution to verify your online connectivity is working with the default settings. If not, you may need to tweak the settings.
- Next up, the setup wizard will ask you if you want to enable features such as having Octoprint check if the internet is available when booting and collecting anonymous usage data.
- The final setup page will ask you to input the name and model of the 3D printer you are accessing with Octoprint.
- Select OctoPi from the list of options.
- Under the Print Bed and Build Volume tab, input the print volume, form factor, and other specifications of the 3D printer. You can adjust the options under the Axes and Hotend and Extruder tabs if needed.
Let's do this now!
Once you get to the main Octoprint tab, guys, click Save Connection Settings in the top left and then click Connect. In this article, I wanted to show you what to do and how to do it. Correct information is only now available on techdataz.com. Now to start printing you must upload the files by dragging them directly into the Octoprint window.
How to Install Plugins
How To Install Octoprint On A Raspberry Pi; Plugins In this article, I wanted to explain how you can further customize your Octoprint installation. Some allow the user to adjust the appearance of the web interface, while others, such as Octodash, allow you to add new features and customize it yourself, such as allowing the user to set up a touchscreen interface on your 3D printer. Actually, dear readers, there are two ways to install Octoprint plugins. The simplest way is to use the Plugin Manager in Octoprint. I've explained how to do this below:
- Open Octoprint's Settings in the web interface.
- Select Plugin Manager from the dropdown on the left.
- Click Get More at the top right of the window.
- On this menu, you can search for Plugins in the Plugin Repository.
- To install one, click the blue Install button to the right of the plugin's title. (You can also enter a plugin URL or upload a file directly from the same menu.)
Plugins can also be installed using a command line. How To Install Octoprint On A Raspberry Pi Every plugin will have a section on the Command Line mentioned on its page. Transfer that line to your Raspberry Pi, copy it, and run it. The file will then be downloaded and installed from the internet.
