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.

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 .
