Extruder not heating up
Not sure what happened but I tried changing the extruder temperature in the g code and then the extruder slowly cooled and didn't heat up again. I even reinstalled repetier host and still nothing has changed, the extruder just won't heat. Wiring i know is fine as it was working earlier.
Also I tried reseting to default settings with G-code M102 and M101 commands and now I have lost everything that used to be shown in the g-code preview.
Very concerned, printers been fine until now plus I have an assesed 3D printing competition in a couple days at my university. :S
