Unloading filament - it gets stuck every single time

Hello, I just got my new Mini+ (I decided to have the assembled model instead of the kit this time).

Loading filament is a great feature, but all the headache starts when unloading filament. I only used Prusament filaments with this Mini+ and the issue is that when I select unload filament, it gets stuck on the extruder section, most of the time. So what I have to do is to disassemble the extruder to find out the filament stuck in there. This is really frustrating.  Sometimes, after the unloading process, I can pull the filament, but I really have to apply force, a hard pull, then I hear some crack noise and the filament comes out. 

Why is this happening? I like the automated filament load/unload, but did I get a lemon printer ? or is there a way to adjust it so the filament does not get stuck on the extruder?


Thank you

This trouble is a combination of extruder design (which is pretty basic), tension lever setting (is guess & try thing) and filament scrubs that collect on grab gear over the time (also related to tension lever setting).
Because your Mini is new, I think it's enough if you try to adjust tension level. If that doesn't help, then take extruder apart and check filament path in detail.

Mini+ with Bondtech upgrade & modified firmware...

If this is a new, fully assembled printer than take the issue to Prusa Support.
