I have just assembled my new 3d printer and it was working good , i have printed 3 or 4 times , one of my prints is the picture above but suddenly it stopped extruding ,i unscrewed the 2 fans to move the hotend a little bit then i reprinted any of the files on SD but nothing worked also i set a small magnet in the extruder motor but i found that it rotated slightly as in the video so how can i solve my problem , thanks.

the motor gear in the bondtech pair, should be fastened with an M3x2 mm grub screw facing the flat on the Motor shaft

Hello,
there may be a blockage in the hotend. Try cleaning the nozzle. It is best to heat the hotend to 260 degrees C. and use a nozzle needle. If this does not help, remove the nozzle and see if the hotend is blocked with a piece of filament. This can be pushed through carefully with a 1.5mm wire. The problem often occurs when printing PLA.
Statt zu klagen, dass wir nicht alles haben, was wir wollen, sollten wir lieber dankbar sein, dass wir nicht alles bekommen, was wir verdienen.

Hi, i removed the nozzle and i saw the hotend but nothing blocked inside it , also while removing the nozzle i removed the upper screw and i found the bondtech gear is not stable , it moves freely , was this the reason ? or may be the problem in the motor itself , Thanks

Thanks A lot, it prints again, the problem was that the bondtech gear unscrewed .
