How is that E3D V6 coming out. I just started having jams printing PLA. And the prints are not coming out great.

Ive gotten a couple jams but it was my own fault for trying to print so hot that the pla was expanding a great deal as soon as it hit the heat break... Once i cooled it down to a more reasonable temp it worked just fine :-) silly me trying to print pla crazy hot(250) to get a higher shine out of it...
It has otherwise been a great hotemd that i have had little to no trou le out of at all...
In a year of printing and maybe 10kg of filament, I haven't had a jam yet with my three hexagons. What I do wish for is better ooze control. In a dual extruder setup, it's very difficult to prevent ooze from the non-printing nozzle--especially with long layer times, models that leave one extruder idle for many layers and specialty filaments like NinjaFlex.
Is the E3Dv6 better than the Hexagon in this respect, or is it just a feed/jam improvement?
I haven't had enough calibrated dual printing prints to give you an honest answer yet.
I've got 2 hexagon hotends, 3mm with 0.4 nozzle .. I chose the Hexagon over the e3d because it was cheaper and there was no ptfe lining tube. my previous hotend had the lining and it caused all sorts of problems
When i moved from a traditional hot end to the e3d i was able to cut my ooze control settings in half. The hot zone on the e3d is so sharp and short its not funny. I have way better control with it. I dont know how it compares to the hex however. As for the ptfe, its not in the hot zone so neve gets exposed to real high temps. I had an all metal v5 and i can say the ptfe liner is way better.
1.75 for me. i would imagine that 3mm would be worse in any situation or hot end. ooze is all from pressure. a higher mass of heated expanding plastic makes for more pressure and more pressure that needs to be relieved.
