MakerFarm Prusa i3v 10" - And So It Begins!

... One thing you need to make sure of is that your hotend cooling fan is running all the time when the hotend is up to temp. Otherwise you will melt your extruder base and your hotend will become plugged up because the filament melts way to far up in the heat break area.

tfast, note that this also applies to shutting the printer off. Don't turn it off while the hot end is still hot. After the heater is shut off, leave the hot end fan running until the hot end temperature is somewhat near ambient temperature before shutting off the printer.

Also note that the e3dv6 hot end is sensitive to the amount of retraction. Multiple people have had similar jamming issues with initial uses of the e3dv6 until they back off on the retraction. IIRC, e3d suggest no more than 1mm retraction length. More than that and you risk pulling too much melted filament out of the hot end heat chamber and into the heat break or hot end heatsink. It'll expand when it cools and can form a plug that jams everything up.

Remember how I warned you that there's a lot of figure out and learn?
