(UMO) Dual extrusion heads different heights

Recommended Posts

Posted · (UMO) Dual extrusion heads different heights

I have a Ultimaker original and I have put the second extruder on but the second is much higher than the other and when I losened it alittle it stated leaking I cant tighten the other anymore to make it higher I was going to try heat proof lock tight and make it so I can loosen it with out leakage to make it level but I was wondering if anyone had any ideas first :) and I have also tryed Teflon tape aswell.

I think on the vimeo assembly video they explain to use the upper screws to change the alignment

There's a simple solution for the head heigh if the Ultimaker method doesn't work for you.

Get a pen, cut the spring in half and place it on the upper part of the aluminum peek holder (the one that it's 4mm tall and has 8mm tall because the screw areas. I just did yesterday on my mod to allow me adjust 2 heads that have 0.7 different height (probably because one peek has many hours and the other it's brand new). This way, with the springs you can do a more selective tension adjustment by using the upper screws. But for UMO standard head you should add 4 springs, since you don't want the heads to have a bad angle. If the springs you use are 'too tall' you can cut them a bit.

BTW I have not tried this on standard UMO dual extrusion, I done it on my working progress magnet changer based on the idea and designs of Foehnsturm -> Link to the forum post

Anyhow if you unscrew the tube/nozzle yes, it will leak for sure.

EDIT: Don't try this on the standard UMO head block. The only way to make it work it's by adding something to keep the preasure of the screw... It's hard to explain, but if you put the springs where I said it will make the ptfe isolator to move and that will make a leak (inside the peek). So to have perfect adjust on dual heads (on the kit experimental) you can only play with the upper screws. The springs could work, but doing more changes than what I said.

    • "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.
