I'd like to hear some discussion too about other hotends. I have a J-Head and a Magma and the Magma jammed so many times that I just put it in the "drawer of forgotten" things, never to come out again. I've been seeing this guy push his Prometheus (
http://igg.me/at/Prometheus-Hot-End/x/6004956 ) hotend that has an adjustable "cool zone." It looks very interesting but is a bit pricier than other hotends.
So yea, any Makerfarm users here using other hotends besides the ones Colin has available when we order the printers?
