Lately I have been printing a figurine and after 1/4 of the print the proccess went on but the filament stopped flowing out and the nozzle was way above the print so it stopped at some point. There was no big clog on it, just the tip was a little covered so I cleaned it and started again (maybe it was because of uncleaned nozzle). Trying the same print, did 3/4 and the same thing happened. What should I do? Here are photos of it
