How to Set Octopi to Remote 3D Printing

3D printing a thing, sometimes consumes a lot of days. Leaving a 3D printer printing alone can waste filament because of unexpected printing error, or even lead to safety issues. Using Octopi to run remote 3D printing can be a good approach. Now, let’s learn how to set Octopi to fulfill remote 3D printing, real-time monitoring, time-lapse photography and auto power cut-off.

Items needed for Octopi 3D printing

1. Raspberry PI

2nd generation Raspberry Pi or above is recommended to run this program. It’s better to use the 4th Raspberry PI for the best performance. 

Note Raspberry Pi 2B has no WLAN card. If you want wireless connection, please purchase a WLAN card and Ralink 3070 is recommended.

2. SD card for writing in Octopi operation system, system file and print file storing.

3. Power adapter for Raspberry Pi

2.5 – 3V power adapter is the best or exclusive adapter for Raspberry Pi is recommended.

8. Card Reader

 

Software Download Prepare for Octopi 3D Printing

1. Download the latest firmware from Octoprint official website: https://octoprint.org/download/.

2. Visit https://www.balena.io/etcher/ and install Etcher (versions for Mac and Windows available )
