Here's what's worked for me. As always, YMMV.

Writing this down for my own history just as much as it might help someone else. I've done two nine machines so far this way. Hope this helps someone!

• Hardware used: EBB36 v1.1 + U2C v1.2
• CAN wiring: Get FEP Wire. Used to recommend 18 Gauge for Power, reclaimed twisted pair from CAT-5 or CAT-6 cable for CAN-H, CAN-L, but I've also received failures eventually from my CAT-6 cable. It's not rated for the movement. Get better cables.
  • I recommend this one from KB-3D if you want something ready to go

Ensure wiring is setup properly.

Easy way to remember: Ensure power is correctly wired on each end (it's different) and then pair CAN-L with GROUND below, and CAN-H with 24V below in each of the connectors. Image references below.

Arch Linux ARM 64 on Raspberry Pi 3 B+ With Full Disk Encryption And SSH Unlock: 2018 Edition

There are multiple ways to get a full disk encrypted arch linux system on raspberry. In this tutorial, we will install a 64-bit arch linux armv8 system, using dropbear as ssh server for remote pre-boot unlocking of the root filesystem. However, it will still be possible to unlock and use the pi as usual, with a keyboard and monitor. We will also create an unencrypted partition in the installation process, usable as a rescue system.

Differences to the 32-bit arch linux arm version:

• probably better performance
• can run 64-bit software
• comes without the proprietary video-driver blobs

After purchasing a humble book bundle, go to your download page for that bundle. 
Open a console window for the page and paste in the below javascript

this fork downloads all formats and does so without using jquery (since that didnt work for me)

note that if you are in chrome, chrome will not download the pdfs for you by default, to fix this
Settings (chrome://settings) --> Advanced --> Privacy and security --> Content settings --> PDF documents --> Download PDF files instead of automatically opening them in Chrome --> Turn ON
