Ok,

Everything is working fine until you re-use a filament previously used and unloaded. When it unloads the filament you have a filament's end which is not clean at all, and doesnt match the requirement: "the tip is sharp, and there are no bumps or bends which could negativelyaffect the movement of the filament strand. Use sharp pliers to cut the tip of the filament".

So when you re-load it, its ok in the FINDA, but sometimes it just failed in the nextruder part... so it can not load it, so you can't continue printing, the filament is not pushed enough so the gear can catch it...

Of Course you can push it manually, but it is very painful to do.

Why the MMU didn't cut the end of the filament when it remove it from the nextruder to change to another one? Doing that the filament will be clean and easy to get it loaded again in the nextruder.

Currently we are preparing a clean filament end to load all the buffer and MMU, but after one usage of the filament and unload the end of this filament is no more clean at all...
