I recently got a CR-10 Mini and its my first printer. I was completely unable to print the little cat it comes with preinstalled on the SD card due to this issue. I was able to slice a Benchy with Slic3r and it printed (Very stringing, still need to mess with settings).

The problem I'm having is that when it heats up the nozzle, some of the filament comes out. I am able to clean it off before it starts though. But on the way from the auto-home to the center, the filament comes spilling out very quickly and when it gets to where it starts to print, It won't stick, and it creates a huge jumbled mess.
