so i swapped the wireds i mixed up and the hot end heated up to 350 not the 220 i told it to (at least thats what the screen said) i then swapped them back and got the same thing. I just bought a new hot end becasue it looked like the plastic never heated up enough but now i dont know what is wrong and why it is saying 350. also the filament is not comig out. now the plastic not looking like it was heating up enough may have been the filament (i have solutech gray and blue) i dont know if i should put the old hot end backing since i know it works but telll me what you think i should do
