My extruder damage the filament

[qdshombre]

Hello,
the filament does not go down because the engine is not running down. when I change the direction of rotation , the engine is running up.
my tension on the card is 0875 V.
what's the problem ?
no problem with 3m test filament, now it no longer works.
thank you
