How to Install OctoPrint on Raspberry Pi Operating System

In this era of innovations, we have a 3-D printer from which we can print the 3D model’s design from the computer, in the hardware form. These three-dimensional printers are very useful especially for visualizing the models of different projects in the form of prototypes. Now a question arises in the mind what Octoprint is and how it is related to the above discussion of 3D printing; so in this write-up we will explore the information about the OctoPrint with its installation on the Raspberry Pi 4.

What is an OctoPrint

The Octoprint is a tool that is used mostly in Raspberry Pi devices and it controls as well as manages the printing-related tasks of the 3D printer. It is an open-source tool that means anyone can access it without paying any cost and can use it to monitor the printing jobs of the 3D printer. Moreover, we can control the accessibility of the 3D printer using the OctoPrint tool and also record the 3D printer jobs.

How the OctoPrint image is burned on USB

To use the OctoPrint on the Raspberry Pi board, we have to download the image file of the OctoPrint from its official website and download the stable version of the OctoPrint:

Once the image is downloaded, we can download the Raspberry Pi imager from its official website to burn the image of OctoPrint either on the USB or the MicroSD card:

Launch the Raspberry Pi imager when it is downloaded successfully:

Click on the “CHOOSE OS” button and assign the path of the downloaded image file of the OctoPrint:

Now choose the SD card or USB on which you want to burn the image of OctoPrint and then click on the “Write” button to burn the image on the SD card/USB:

After the image of OctoPrint has been burnt on the SD card/ USB, a message will be displayed and click on “Continue”:

How to set up the OctoPrint on Raspberry Pi

To use the WiFi on the OctoPrint, we have to configure it, for this purpose, we will connect the USB with the PC and find out the file with the name of “octopi-wpa-supplicant”:

Now go to the line of “# WPA/WPA2 secured” and remove the “#”, then replace the “Put your SSID name” with the wifi name and “SSID password” with the password of your wifi router:

Scroll down the page and there will be country names written in the file, remove the hash(#) sign of the country where you are using the OctoPrint, as we are living in the United States, so we will remove hash from it:

Close the file after saving the changes and to use the Webcam, open the file with the name “octopi”:

Remove the “#” from the start of line 24 of the file:

Also, remove the “#” from the mentioned two lines in the “Configuration of camera HTTP output”:

Once done save the changes in the file and connect the SD card /USB with the Raspberry Pi 4 and connect the Raspberry Pi with your 3D printer.

Note:  After booting the Raspberry Pi open http://octopi.local in the browser, the Octoprint dashboard will appear: follow the onscreen instructions.

Conclusion

OctoPrint is a tool that is used to manage and control the printing jobs of the 3D printer attached to the Raspberry Pi device. We can print the 3D models of different designs to visualize the hardware prototypes of the projects. In this write-up, the method of installing the OctoPrint and its configuration on the Raspberry Pi 4 has been explained.
