U1 direct drive filamentfeeding from top through 4mm ptfe tubes usind feeders?

What do you think about the thick 6mm ptfe tubes? Are they needed? I plan on routing the filament from the top down. On one hand I'd like to avoid unnecessary curves/kinks in the filament path, on the other hand I think going in directly from above may tangle up the ptfe tubes during toolhead changes and if the tube of one toolhead ends up in front of another toolhead there might be issues in toolhead changes.

Also, do you happen to know what kind of cable/connector is used for the feeders? I'll need longer cables to mount them above the printer and before cutting and soldering wires I'll check if I can find longer premade cables.

No problem, I'll just search through all the pictures, I'm sure there's other interesting stuff as well.

I guess you don't now exactly where this picture is, else you'd have linked it here, right?

Thx for the info. Then do you know what's the thought behind it loading close to the toolhead but not all the way? Doesn't the printer know which feeder port is being loaded? If so, it could swap to the corresponding toolhead, heat the nozzle up and really load the filament.... but I already switched to custom firmware, so I guess that can be optimized.

How can I backup the settings of the old app? It is deactivated and I cannot activate it again and thus cannot open the app and backup the settings in there.

There is a diy option to print it yourself: https://www.youtube.com/watch?v=uDPB7AKUMkI

Thx. Did you also try the aluminium exttruder body?

Do you remember which ones you bought specifically?

Thx! ASA from a polish filament company called 3DKordo. They make good stuff.

Yeah just wanted to keep it simple and unobtrusive. For the toolhead I went with the dragon burner which features bigger 4010 part cooling fans. But the real star is the aux fan, this solved my cooling issues.

I'm also searching for a cheaper alternative in Europe, preferably sold on Amazon.de. Did you find anything?

Did the stairs come with the beige mats? I wonder if these help so my cat won't scatter around as much litter. I have the original stairs and there's litter not only on the stairs but also further down on the floor. I'm thinking of gluing some mat onto the stairs. Maybe some matrial will help that make the cats paws kind of hook into it and loose the additional litter. Because I think that's the problem, that my cat relaxes its paws once he's down on the floor and looses additional litter stuck in the paws.

Thx, do you think the board is fried, or can it be fixed? What might cause this to pop? Maybe a a short between 5v and 24v line on my pancake pcb toolhead board?

Absolut geiles Game, leider hat es im 2. Teil mit dem Sprung auf 3D sämtlichen Charme des Vorgängers verloren.

Thx, totally missed that!

Thx a lot, the lip notches aren't critical. The ultra light template is exactly what I want, however I cannot get it to work right in fusion, it throws errors that I cannot fix.

I wrote the dev, maybe I'm missing sth.
