Check this printer quality and videos.. 150mm/s and that quality? Duet3D + Corexy + stable frame = woa.
What do you think @jonnybischof ? The prints and videos are quite impressive. Ofc I can't be more a fan of the duet3d, the steppers and the easy configuration of the board are just awesome (IMO).
The build looks awesome indeed!
Probably very tedious and complex to build (so, not a good idea to sell these as diy kits) but the result is really impressive. It's close to what I wanted to build for my third prototype. But I didn't even get past assembling the aluminum frame - it was too much of a pain to get everything assembled perfectly.
He used 1515 extrusions which I would personally find to be too flimsy - But that's only until the panels are mounted. Note that Misumi 1515 and 2020 rails cost pretty much the same - smaller is less common which makes 2020 the better choice for price / performance ratio:
HFS3-1515-375 is 1.61 EUR
HFS5-2020-375 is 1.71 EUR
HFS5 is more than 2.5 times as strong as HFS3.
I also use M4 screws instead of M3, because they are infinitely stronger, but not much larger. Note that I usually tighten my frame screws "quite" a lot... xD
His printhead and extruder drive are huge. Really impressive that he can still achieve high speeds. I wonder how much of a difference it can be when you have a much smaller and lighter printhead.

I would love to see a zge on that or a 60grms pancake motor.
Making a tension system on the corexy is much eaythan the um since it has only 2 belts that tight near the hotend. The problem is the find the right amount of tension. About how to calculate that there’s no much info.
I like the basics of the design, but i also dislike some things. For example, why use no top plate like in the UM design? That would make sure that it is square and add quite a lot of rigidity. Also, i would not trust that single rail with being rigid enough with a large head like that, i would at least add a small aluminium profile.
Man I would love to buy a frame or have access to cnc stuff to make something like this. In the end there’s really very few places to just click/buy a setup like that. And nearby fablabs here in Madrid are very weak. So no option to go cnc a frame to save cash.
Or the most important missing skill for me, being able to design it.
Indeed a top part could add more stability, weight always help also.
I would be just really happy to be able to print at 100mm/s without the ugly rigging I get at 50-70 but ofc my printers frames are wood.
I have begun collecting parts for a DICE, and it will be built with high-quality parts only, so HIWIN rails etc. Recieved the water jet cut parts a few weeks ago, and i have a order with René for the water cooling parts
That one will most probably be able to print at 100mm/s without any noticeable ringing

Yeah that's pretty small and compact. I like that design.

What about when those belts settle in and wear a bit/stretch?
That should only happen if you use belts beyond their rated loads (or have some really crappy belts). If not - they aren't supposed to stretch noticeably.

Where did you order the plates from?
All the interesting 3D-printers I have found requires plates to be cut. And I don't have tools for that, nor do I know any place where it doesn't cost a fortune to have them made.
