Hey guys, I am very new to 3d printing and assembled my printer myself. It worked great for the first 2 prints but now I am having all sorts of issues with my extruder. First off when heating up to the desired temp (210) it just keeps heating up till I unplug it for fear of it getting too hot. Once I get it to the temp I need by lossening the wire of the extruder to the mainboard, once it starts printing the extruder drops in temperature to about 185.
