$ wget -qO - https://download.alephobjects.com/ao/aodeb/aokey.pub | sudo apt-key add -

If using Ubuntu Trusty or an earlier version:

$sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak && sudo sed -i '$a deb http://download.alephobjects.com/ao/aodeb jessie main' /etc/apt/sources.list && sudo apt-get update && sudo apt-get install cura-lulzbot

ERROR: Cura depends on python-wxgtk3.0 which cannot be installed on Ubuntu Trusty. Solution:

$ sudo apt-add-repository ppa:adamwolf/kicad-trusty-backports
$ sudo apt-get update
$ sudo apt-get install cura

ERROR: When installing on Ubuntu Xenial, there was an error of dependency: "cura-lulzbot : Depends: libssl1.0.2 but it is not installable, Depends: libreadline7 but it is not installable". Solution: Edit /etc/apt/sources.list and modify the alephobjects repository from stretch to jessie:

deb http://download.alephobjects.com/ao/aodeb jessie main

It is necessary to add user to dialout group. Use usermod (a guide).

Usage:

$ sudo usermod -G GROUP-NAME USER-NAME

Check the groups before executing the command!

$ groups
$ sudo usermod -g USER -G USER,adm,cdrom,sudo,dip,plugdev,lpadmin,sambashare,dialout USER

Note: Replace USER by your user account. All groups must be included in the -G option.

Configure 3D Printing (Cura) †

For configuring 3D printing, read the User Manual where the usage of Cura is also written.

Left click: select the object, etc.
Right click: popup menu.
Right drag: Rotate the view.

Select "Overhang" view (right top) to see the contacting surface.
Select "Layers" view to see the trajectory of the hot end.
Use "Print support structure" when the model contains floating parts (no structure underneath).
When you change the material, find a configuration for the material from the pull-down menu. Change "Material ease of use" and "Material".

Special Tool Head †

Special tool head (LulzBot Mini Flexystruder Tool Head) is necessary when printing a material such as NinjaFlex. We have the tool head. For replacing the tool head, read the instruction.

Running Cost †

The cost of PolyLite PLA is approx. 4,100 JPY/kg. So the cost of a 10 g object is 41 JPY. NinjaFlex is more expensive: 11,500 JPY/kg.
