Does anybody know what this cable is for (thought it is supposed to be for an aditional fan?)?
I Just calibrated the printer and was up to heat the printhead an feeding it with the filament - but the printer does not exttrude the filament. Any Ideas, someone?
it is just blinking red blue :/
If it reaches the 200+ degrees its just beeping one time - not exttruding and the temperatur falling back again:
The red/black wire is actually a ground wire ( as per a previous note somewhere on the forum). They recommend that you connect it to a metal part/screw on the extruder.
