Need help installing Cura


Info: Acer, Extensa 5230E, 2.30GHz x2, 1.9Gb memory, 64 bit, Ubuntu 14.04 LTS, Trusty

Just Received my TAZ 5, my first 3D printer, I’ll start off by saying I know absolutely zero about Linux. I installed Ubuntu on a old laptop I had laying around and downloaded the pre-compiled package “cura_17.10-7457_amd64.deb” to my desktop, I double click this file and a window pops up “Ubuntu software center” and I click install. After that is finished I find an icon “Cura” under “search your computer and online sources” when I click this nothing happens.

Also I stumbled across how to use the Terminal and tried my best to follow the direction how to install it that way but I get an error message. See below. What am I doing wrong?

Your help is greatly appreciated,

If you don’t know linux well, why did you choose as a platform for Cura? Are you shooting for a “dedicated” workstation for printer control? If so, an alternative would be Octopi (Octoprint).

Install Cura on your normal PC/laptop, slice your projects, then upload to Octoprint via web interface. Fire off the print and monitor via webcam interface.

There are some instructions here…

Good luck!
