To print stuff on your 3D printer you either handle those nasty sd-cards :/ or you have a pc attached to your printer running all the time.

To “FIX” this i decided to set up a raspberry pi with octoprint and have this always attached to the printer.

I baught the Raspberry Pi 3 and followed the very detailed instructions on the octoprint website in the download section.

I have done this on my mac so i didn’t need a sd formatting or iso install tool. After downloading the octopi iso basically just open the terminal an follow the steps:

identify the sd card
diskutil list
in my case its disk3 I reference the number from now on as #
next unmount
diskutil unmountDisk /dev/disk#
next copy the image
sudo dd bs=1m if=image.img of=/dev/rdisk# conv=sync
this may take a while

Then and this is really important they dont just kid around by saying this (i ignored it the first time :/ )

Configure your WiFi connection by editing code class="highlighter-rouge" octopi-network.txt on the root of the flashed card when using it like a thumb drive. Important: Do not use WordPad (Windows) or TextEdit (MacOS X) for this, those editors are known to mangle the file, making configuration fail. Use something like Notepad++, Atom or VSCode instead or at the very least heed the warnings in the file.

And then you should be up and running! I had no problems what so ever! It even autodetected my logitech webcam for the survaillance feature and timelaps feature!

Don’ forget to print your own Raspberry Pi Case 🙂
