Prusa Mini purge ok but does not extrude when printing

Hello,

Having an issue with the Prusa mini. I can unload the filament ok and reload it just fine. When reloading, the filament purges just fine. However, when I print nothing comes out of the nozzle. See attached videos. Any help will be greatly appreciated. Thank you.

Does extruder stepper motor rotate when you print? Have you tried to make factory reset?

Time to narrow things down...

As @bogdanh suggested, is the extruder working during the print?

A clog? Try some cold pulls 

Nozzle too close to the sheet? Post a picture of your first layer calibration. Use this method instead of built-in, easier to interpret: https://forum.prusaprinters.org/forum/original-prusa-i3-mk3s-mk3-assembly-and-first-prints-troubleshooting/life-adjust-z-my-way/

Slicer settings okay? Are you printing at too cold a temperature? You can save the project as a 3mf file from PS's File menu, ZIP it, and upload it here, so the good folks here can check your settings?

Beyond that, I can't really think of any other reason.
