I've slowly been learning some of the cool features on this new 3D printer. One really neat thing is filament run-out sensing. If you run out of filament the printer will stop. Change in new material, press a button and this will pick up where it left off just like nothing happened.
I've been printing filament stands while using up some of my very old filament that's been out in the open for at least a year. So as the spool runs out swap in a new spool. Even if I do not have the same color.
That is the result of running out twice.
The control software also has a feature where I can tell the printer to stop at a given layer in the print. This allows you to say insert a nut into a cavity for a captured piece of hardware or to change colors of your filament.
The more I learn about this machine the more blown away I am at it's capabilities.
