The instructions describe how to set the printer up with Repetier-Host. Ex-parrot uses Octoprint. Print time can take hours, so I decided to use Octoprint as well, installed on a Raspberry Pi, so that my MacBook won't be tied down while printing.
I'm using the latest version of Octoprint (1.2.5). I tried installing the latest version of Cura (15.06.03), but the option for non-Ultimaker printers seems to have been removed, so downgraded to 15.04.2, which is working well.
Below are screenshots of the settings which Ex-parrot recommended to me. I've done about a half dozen prints so far and haven't felt the need to make any changes. Comments with suggested tweaks are welcome.
