I ordered this part:

http://www.ebay.com/itm/151942829352?_t … EBIDX%3AIT

One concern I have in fitting it on the Davinci 1.0 is how to secure and center properly the 6mm pipe into the 8mm hole on the Davinci carriage. I guess an upper and lower nut and some thermal material ? Centering is of concern if later I will do the same on a Duo. What adapter sleeve would I use to fill the 1mm all around ?

Buy muffler repair tape from an automotive store and use it to build up the section of pipe that fits in the heat break.

What steel screw, the height probe ? On the Duo, both heads are the same, one has the screw/probe installed, one just has an empty hole.

So far works great. I really like the temperature responsiveness on the new head.

The auto level (steel screw) probe. So there was only one probe screw installed in your printer. It does make scenes you would only need one. It's amazing the difference in hotends lengths. I wish I found this thread before buying a E3d hotend it would have saved me a lot of work.

There is a fair bit of work involved but I reckon it's worth it for the increase in print quality and compatibility with other filament types.

Yes, the Duo has only one probe, on the right side head.

I am still going to convert one of my 1.0's as scobo suggested just to explore the possibilities. I am thinking to change out at some point the right head on the Duo and get another head set as spare parts since who knows how long XYZ will offer them for sale.

So far it works very well, but I used ABS and Cycoloy home made filaments only, no HIPS yet.

I believe it's worth the trouble just so you can change the tip. Mine was worn down at a angle and the filament was coming out at the same angle. So I removed the assembly and sanded the tip and cleaned the hole. What a major difference in print quality it was back to new. I will never use AUTO level again after that mess. Manual level has 5 points to check and is much more accurate.

Head replaced. So far so good.

An interesting observation is the difference in size and shape of the old vs new heads. I would say the thermal mass of the new head would be almost half of the old one and it heats a lot quicker. Maybe better temperature control and less heat creep so maybe that is why they claim it can print PLA ? I guess I will test that later.

Check out the pictures, note also the much more pointed nozzle. Interesting, maybe it will be worthwhile to change the right side head also.

Have you got a link for that hotend please. I have problems with my left one so I don't use it anymore.
And your one looks like a easy swop over.  Nice mod dude.

http://us.store.xyzprinting.com/?cateId=0&navId=2 select the Duo heads. They do not sell the heads only, just with the board. Expensive.

That's what I thought. It doesn't have the little metal stub the auto cal uses either.
Be interested to hear how it performs.

But there is a hole for the steel screw it's has been removed or never installed. The old hotend has the steel screw in it. Hopefully he will respond so we can find out for sure.

Edit: I see that he did respond.

Is that the MK8 hotend ?
Looks nice, and I see you're still using the stock thermistor.

No, it is a new Davinci head I purchased as a spare (paranoia). It is expensive and you have to purchase it with the entire board.

Sorry for the confusion. I just fitted it temporarily until I receive the MK8 so I can cntinue printing. The dual heads w/ board are $160 plus shipping at the XYZ store and i bought one a while back since I had a feeling probably that would be a part I might need in the future, having 3 Davinci printers (one duo and two 1.0's)

That's not a V8. That's the upgraded hotend for the Duo 2.0. I just looked at mine and it's the same.

A V8 ???
Think you've got the wrong forum mate.
