Hi All.Does anyone know the specs for the thermistor in the early Cocoon Create.Tried a couple from eBay and still getting fault. Temp display jump to Def/215.Problem started with printer loosing power halfway through longish print (sometimes). thermistor read open circuit and can't see any info on the thing, maybe my eyes?No printer for 3 weeks now, getting withdrawal's.Any pointers appreciated. Roy.
