V2 Hot end upgrade setup

Recommended Posts

So apparently there is only one way to mount this according to UM.

I am assuming the flange part has to be flush with the aluminium block when mounted. If this is true then the nozzle with screw part stick out the bottom and is not flush with the bottom of the aluminium block as before. And vice versa, if you mount the nozzle flush, the flange is not flush on the aluminium block.

My questions is which way is this "one way to mount" the correct way? And honestly I think I will still use teflon tape just in case its as good as the original "easy to mount" hot end.

Hi Danluc,

Despite what they say, there is more than one way to mount it... But if you look at the pictures on the wiki it should be pretty clear. http://wiki.ultimaker.com/Hot_end_v2

The flange should go against the PEEK part, leaving a gap between the PEEK and the Aluminium block. There should be no gap between the nozzle and Aluminium block.

I've had the V2 nozzle for a while now and have not had any leakage, with no teflon tape. I did have some on leakage the previous hot-end version. The design of this nozzle should reduce the opportunity for leakage because of where the joins are. I think it is still possible for some leakage to occur on this one, but it is much less likely. In any event, it was never much more than a cosmetic issue as I'm not aware of a little leakage around the nozzle causing any serious harm for anyone.

I didn't look in the right place thats for sure. Thanks for the link.

I will put teflon at the nozzle, below the flange and above it just in case. Printing with white look like crap when you get the leaks of black burnt PLA.

Also there is no way I will be replacing the wooden parts and taking all that apart lol especially since I'm making another printer. But I will give it a try soon.

PS: The easiest way to make sure the tube doesn't pop out is replacing that collar with any quality one like from a 1/4" SMC push connect pice so I think above the PEEK it will stay the same for now.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
