Posted · filament coming out of the nozzle seems too thick

the first prints I did (with PLA) are very smooth when I touch the surface. After few days (the first filament coil not half consumed) I begin to get under extrusion problems: nothing printed, or only a part of the printing.

I made several "atomic method" in order to clean the nozzle, also, I tightened the filament feeder, and now, the filament coming out of the nozzle seems to be very thick: when the print is finished, the surface is not smooth: with my nail, I can move some filaments on the surface of the print,

Please see this video: http://www.softysoft.fr/_3dprint_problem.mp4

Thanks for help.

Best regards
