so, i just got my first 3d printer. it’s an anet a8. after much research I ordered with it a pair of mostfets. assembly went well enough. trouble is on first power up the extruder started heating up and didn’t stop. the temperature is tracked properly up to 280C but afterwards it goes to def, i’m pretty sure it keeps heating after def. does anybody have any advice on what I can check for a solution? I’ve googled and forum crawled, there was one similar post but it was a dead end post from a couple years ago.
