If you have a 3D printer without an IP connectivity (e.g. ethernet / wi-fi), but you’d like to gain some remote control and monitoring, then OctoPrint will help you. Essentially, you connect a Raspberry Pi to your 3D printer via a USB cable, and then that enables you to control your printer via a web interface and/or mobile application. For more information on OctoPrint, please visit https://octoprint.org/.
Before you get started, please make sure you have the below:
- Raspberry Pi (ideally a Pi 4B, but the Pi 3B/3B+ will work)
- Micro SD card (minimum 32GB)
- The ability to read Micro SD cards via your computer
Installing OctoPrint and OctoPi
Download the OctoPi image from https://octoprint.org/download/
Download and install the Etcher application from the Balena website.
Connect your Micro SD card to your computer, but do not format it if you’re prompted to do so.
Click ‘Flash from file’, and select the OctoPi image that you downloaded in step 1.
If your Micro SD card is not selected in the middle section, click change, and select it.
Click the ‘Flash’ button, and wait until it’s completed installing.
If asked if you want to allow changes to be made to your computer, select ‘Yes’.
Wait for the installation to complete, it can take a little while, depending on the speed of your card.
When the installation has finished, visit http://octopi.local in your browser to start using OctoPrint.
