Just as the title says, the hotbed works fine and it'll go all the way to the desired temp. But the extruder, the important bit from what I understand, doesn't do diddly, just cruising at room temperature no matter what I do. I've tried unplugging the thermistor and plugging it back in, but other than that I'm not much of an electrician to see if the thing is actually getting power. Everything else works fine, except the heating for the extruder. Any tips? I just finished building this thing, and please, for anyone trying to help me, speak to me like I'm a complete novice because I have no idea what I'm doing when it comes to 3D printers. Computers are my game, printers of any kind are my bane.
