Cura LulzBot Edition is a Free Software 3D printing solution offered through our code repositories.
System requirements and the End User License Agreement can be found on LulzBot.com/Cura.
Cura LulzBot Edition version 2.6.66 contains firmware standardized for use with all LulzBot Mini 3D Printers, and contains important bug fixes. However, once your firmware has been updated to 184.108.40.206, GCode files sliced with earlier versions of Cura LE will no longer be compatible and will have to be re-sliced using the latest version of Cura LE. We recommend using the latest firmware included within Cura LulzBot Edition to maximize long-term compatibility. Users that need to use existing GCode files can restore compatible firmware (220.127.116.11 or below) through Legacy Cura LulzBot Edition v21.08.
The commands below will delete the older slicing profiles and 3D printer settings from previous versions of Cura LulzBot Edition. Back up the files and folders listed below first if any customizations have been made.
Open a terminal.
Run the following commands:
cd; rm -rf ~/.cache/cura-lulzbot ~/.config/cura-lulzbot ~/.local/share/cura-lulzbot
In order to use your favorite package manager you'll need to add our package repository (repo) public key to your local machine and our repo to your sources.list file. Use the following command to list display your Ubuntu version:
Add our repository public key to your local Ubuntu machine by running:
wget -qO - https://download.alephobjects.com/ao/aodeb/aokey.pub | sudo apt-key add -
In a terminal send the following command:
If using Ubuntu Trusty or an earlier version:
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak && sudo sed -i '$a deb http://download.alephobjects.com/ao/aodeb jessie main' /etc/apt/sources.list && sudo apt-get update && sudo apt-get install cura-lulzbot
If using Ubuntu Xenial, Zesty and Artful:
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak && sudo sed -i '$a deb http://download.alephobjects.com/ao/aodeb stretch main' /etc/apt/sources.list && sudo apt-get update && sudo apt-get install cura-lulzbot
If using Ubuntu Bionic, Cosmic, and Disco:

If you encouter errors, repeat the commands one by one:
Make a backup of your sources.list file:
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
Add the repo location to the end of the sources.list file (change the deb version to match your local system):
sudo sed -i '$a deb http://download.alephobjects.com/ao/aodeb jessie main' /etc/apt/sources.list
Refresh the package manager information (aptitude users replace "apt-get" with "aptitude"):
sudo apt-get update
Install Cura from our repository (aptitude users replace "apt-get" with "aptitude"):
sudo apt-get install cura-lulzbot
If you prefer to use one of our precompiled Cura packages, download the appropriate .deb file for your system architecture from one of three archives:
Once downloaded, in a terminal navigate to the directory containing the file and send the following command:
sudo dpkg -i cura-lulzbot-version.deb
If you have trouble connecting to your LulzBot 3D printer, you may need to add your user account to the dialout/tty serial access group. In a terminal, send the following commands:
sudo usermod -a -G tty $USER
sudo usermod -a -G dialout $USER
Log out of your current session and once you log in again, you should have port access.
