Hi,
I'm having some trouble heating my extruder, which, until now, was working perfectly alright. It would rise up to 240 C in a minute, and now it's struggling to touch 185 C. When i heat the extruder, it rises with ease quickly, as it approaches 150 C, it starts slowing down drastically, and when it goes up to 185 C it almost stops rising. The increase is only about 0.2 every 2 seconds. I measured the output going into the extruder and it was about 11 volts throughout.
Would anyone have any insight on this?
