Ok so i recently got a Flexystruder and i got it setup and the software setup and updated the firmware though if i try to print with ninjaflex i have to push the filament in myself and i can see it trying to extrude the filament but it just isnt. Even when i push the filament inside myself it wont even print right or like a normal printer would because it extrudes in a weird way where it does extrude for about 10 seconds, then stops, then starts again. I completley followed the directions to install this thing and i wanna know whats wrong with it. Note that i have tried higher temperatures and it still didnt work ---

It sounds like the hobbed bolt is grinding your fillament out. You’ll want to call support probably. It could be a hotend to extruder body allignment issue, a thermistor not reporting the correct temperature issue, bore lock due to unusually large ninjaflex (rare but i have seen that before) or something else. ---

Will filament extrude if the toolhead is above 5cm above the bed? If yes, then the autolevel is not working correctly. Try cleaning the nozzle and touch points.
