We’ve been secretly, in a completely none secret way, working on a customized Cura for use with the LulzBot TAZ and the coming LulzBot Mini. The changes have been mostly in graphics and quick-print settings. Credit is still owed to David Brahm for developing Cura, as Cura LulzBot Edition is still largely the reliable software developed by David with Ultimaker.
You can download the most recent revision packages of Cura LulzBot Edition at http://devel.lulzbot.com/mini/software/cura/packages/current/. You can also find the source at https://github.com/alephobjects/Cura/tree/AO-build.
The software is still in an early testing phase but is largely usable. If you do find any bugs or issues please submit them to the github page, https://github.com/alephobjects/Cura/issues. There is ongoing work so make sure to check back on updated revisions on devel.lulzbot.com that may include fixes to your found issues.
To use the customized quick-print settings you will need to run through the Add new machine configuration wizard. Selecting the LulzBot TAZ or Mini in the configuration wizard will load customized quick-print settings for the selected printer.
If you have any questions, feel free to ask here or post an issue on Github.
