Firmware Notes:

We recommend using the latest firmware included within Cura LulzBot Edition to maximize long-term compatibility. Users that need to use old GCode files can restore compatible firmware ( or below) through Legacy Cura LulzBot Edition v21.08.

Cura LulzBot Edition versions 2.6.69 and above contain firmware standardized for use with all LulzBot Mini 3D Printers, and contains important bug fixes. However, once your firmware has been updated to or beyond, 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.

Cura LulzBot Edition version 2.6.69 includes proposed LulzBot TAZ 5 slicing profiles with built-in filament temperature settings. Marlin Firmware 1.1.5 and later removes the built-in filament temperature presets from the Graphical LCD Controller menu. Users that prefer to use the filament temperature presets included with some legacy firmware can use the firmware included within Legacy Cura LulzBot Edition v21.08.
