What kind of objects? I'm running out of test to do, last test atm is doing retraction calibration and seems 0.3mm retraction for my 1.75mm um2 head is more than enough to avoid any stringing at 225C 0.2 layer 70mm/s
That's the test just finished right now.
If you have any object to print, and tell me the speed/layer/temperature I could do more stress test with it.
Also, I agree, this delivers less blobs, much more exactitude from extrusion since the filament doesn't flex, and ofc, this shows how on my other bowden umo+2 I need 3.00 retractions to avoid stringing but with gudo zge I only need 0.3mm. That clearly shows how much delay there's on a bowden vs a dd. I'm so amazed with the prints with flexibles, check my twitter, I been doing lots of tests and prints this past days.

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

gudo and neotko congratulations on an ingenious and apparently very successful design! I've been a long term 'lurker' on the forums here, and have been using an Ultimaker 2 Extended since soon after they were released to make architectural models. I was a long time user of Makerbots before the Ultimaker and see the Bowden tube system as the only downside of what is otherwise a much better machine than any of the Makerbots. We often print extrusions that vary only small amounts in the x and y over the duration of a print, such as walls, boxes, towers etc. As such the inherent inaccuracy of the elastic Bowden tube is very noticeable, particularly with layer heights of say .3. We need to print relatively large things quickly and neatly and don't care too much about strength. I think generally the 3D printer market doesn't cater very well to us architects.
I would be extremely interested to see a bill of materials and print geometries for this 'add-on' and would be equally excited if you were to offer it as a commercial product. I've come out to join the forum to ask this; I hope you'll welcome me aboard the Ultimaker forum train!
Thanks for your hard work.
