MMU2 for finishing almost empty spool
Does anybody have tried printing with almost empty spools for the MMU2 automaticly change when ending one ?
I didn't see any post or guide explaining how to do but it's sell as a posibility.
I did sliced a part in Single mode and start a print with a short piece of filament but it passed the FINDA and nothing happened.
(By the way why the printer didn't stop at least ?)
I think that for an effective change you still need a little purge tower for ramming and get a sufficient pression in the nozzle when loading a new filament, but if you slice in Multi material with a single part, there's no purge tower.
So how are we supposed to do ?
Thanks

In firmware, turn on auto depletion

Thanks, I tried but it didn't work.
I sliced in single mode and in MM mode but none worked, the filament pass the FINDA and nothing happen.

You have to activate the filament sensor too.

Really ?
I thought it was no more used, for anything.
Is it reliable for this application ? lol
So how does it work, when it detects the end of a filament, it extrudes till it passes the bondtech, then load a second filament that will push the previous one ?
What happen during this operation ? Is the head place in a corner ? Cause you will need a pause the time to load a new filament and I'm sure a little underextrusion during the transition.
Whatever, I will try soon, thanks for answering !
This application is really interesting and anounce in the PRUSA's video but they didn't explain how to use it... at least not in the handbook...
