Did you consider using a carbon fiber square rod instead of a steel one?

 

If I remember well he did, and it did bend quite fast. But don't take my word for it

Wonder why there isn't any more discussion after August 7,2017? This is a fantastic design and topic.

Gudo and I wanted to give an update on the status of the ZGE So, long read ahead! (but interesting) Why we made it Gudo and Neotko are moving forward this extruder because we are always pursuing

A fast overview of Gudo's ZGE, sorry for the bad sound quality but the holidays are almost over! Also, Gudo passed me the BOM of the ZGE, so you guys can start collecting stuff for it. I person

Hi all! Hi amedee !

The" carbon square rod was the first thing I tested, it had immediately delaminated under the extrusion torque , also, it would not have been compatible as a rolling way for the slider bearings.

Hi Gudo,

Looks great !! Do you only work with direct drive now or do you sometimes switch between the 2 systems?

greetings

Ed

You could do that, if you design a different top head and a holder for the extruder top. I thought about that long ago but it really doesn't make sense to go back to bowden when you use DD. It just works great.

Hi to all,

Hi Ed

Thanks ! If go back to the Bowden system it means that the DD doesn't work as well as it. That's far from being the case, as neotko wrote, the ZGE in addition with the Bondtech gears just works so great that you will not want to use the Bowden again ;)

Indeed, I see no reason to go back. I still have to adjust my slicer parameters to get everything dialed in properly, but in the worst case, the ZGE performs at least as well as the Bowden setup.

If you would need to go back (e.g. in case you broke something like the stepper holder and need to reprint it), it is quite easy, you just need to remove the custom hot-end cover plate and re-install the Bowden. It is not practical to switch back and forth, but if you have to, it should not take more than 10 minutes.

Did I miss something? Are the STL files already available?

I have read this thread a few times, but I do not find anything about the files.

Just to know if I can start with the adjustments.

    This is one of the best upgrades I have put on my UMO+ so far...after switching to the UM2 printhead. It just works...without hazzle...and with flexible filaments. I even managed to use up all of the "crappy" Ultimaker filament that came with my printer (the faulty batch that snaps as soon as you look at it) :D

    I think this should be a standard for new printers, at least for single nozzle printers. But it might be complex with dual nozzles.

     

    Maybe only the coupling halfway close to the head should not be there, it adds complexity.

    Gudo made a version for dual, very doable for um3 style dual. He also made de design for a BCN 3D style. It could even be great for prusa style to weight (but ofc that machines problem is the bed weight Y moves)

    It is...we are at least a few who are using this extruder on our Ultimakers and it works great :)

     

    The main reason why the discussion stopped is that the creator is, sadly, no longer alive :(

    are you purely saving the motor's weight with this? so in case of a pancake 160g? (still a lot but i'm curious!)

    The purpose is to reduce inertia. Each gram less improves print quality, because you get less vibration, less "ringing" around corners, less overextrusion at corners (the nozzle can accelerate and decelerate faster), and you can print faster. A drive motor weights a lot, compared to the rest of the head. If the head is lighter, the gantry can also be made lighter, which further improves print quality.

    Hi all!

     

    First of all, that's an amazing contraption 🙂

     

    In your experience, with what filament hardness should one switch to a direct drive on the UM3? I am looking to get printing with NinjaTeks Eel filament (Shore 90A) but not sure if this would require an upgrade like the Zero Gravity direct drive.

     

    Thanks for any and all insights!

    Added Gudo XY Core for UM2GO that has a couple of little treassures

     

    - Adds a smooth rod to the X for extra rigidity
    - Has his Bed BELT driven mod. I never tested this, but he was Very happy with this, very interesting mod treassure. This mod can be used on any UMO+ UM2 as long as you have the motor (bondtech style one for force) and you adjust the belt size etc.

    - Gudo also included a couple of extra images of how to assemble stuff, very important to have at hand for a build of either version
