Hi,
habe eine PM geschickt.

I think it depends on the model. I printed watertight models with Cura 2.4 on the UM2+ without problems.

Hi Sima,
and welcome to the forums!
This sounds like either a temporary problem or a bug. Take a look at this guide and reset your Cura settings:
https://ultimaker.com/en/resources/20499-reset-cura-2-1
If it happens again, look inside the "cura.log" file for any hints as to why this happens.

Hi,
I don't know what "Custom 4" is but I assume it is a printing profile in Cura.
You can export a profile by accessing the settings, selecting profiles and then the profile and "export".
If the maker space uses Cura 2.4, you could save you entire configuration including the model on the buildplate as a project. For this just access "File" and then "Save project".

On my Mac Cura 2.4 does not behave weirdly. CPU consumption is normal or else I'd hear it when the spin up.
Sometimes they do but only for very complex models.

Hi,
and welcome to the forums!
If you want to print with PVA and a BB core, you need to tell Cura which extruder to use for support material.
If by contrast you want to print with two AA cores, then check out the manual section about merging models.

I leave Cura open over several days too - on the Mac. After working on print settings I usually minimize it and start the print. If I need to change print settings, I access Cura, change settings and start another print (sometimes over network sometimes with the USB stick). So far I didn't notice anything unusual. But I'll keep an eye on it.
Is it just a display problem or does the changed setting(s) match the preview in the layer view?

Hi, and welcome to the forums.
I doubt Cura would run on a Raspberry Pi properly (if it starts at all due to the OpenGL version maybe).
Usually the workflow when preparing files for printing is to run the slicer (Cura for example) on a desktop computer and then use the resulting .gcode file to print on a 3d printer.
You could use the Raspberry Pi with something like OctoPrint:
But if you have no experience with 3d printing, I wouldn't recommend it yet.
As for the USB stick - as long as the computer where Cura runs on recognizes the stick, you should be fine.

I have a weird problem with the Olsson Ruby. Printed only PLA with it and it worked fine until now. Suddenly it wouldn barely extrude and would grind down filament. At first I thought it might be the coupler.
Fun fact: I haven't changed the coupler ever since I've installed the extrusion upgrade kit... So this thing was super durable.
However, I changed the coupler, inspected the bowden tube, the feeder (no obstructions) and the Olsson block.
It would still not work. The Olsson Ruby nozzle looks absolutely fine. Since it has a translucent tip, it is pretty easy to see through and it is completely clear. The inner walls look fine too.
If I mount another nozzle, the extrusion is fine.
Any ideas? Did I miss something?
Btw. that's how the filament tip looks like after performing a couple of atomic pulls (perfectly clean)
-
Could be a bad temperature sensor which reports false readings and the heater does not heat up the nozzle properly. The pattern on the vertical walls look somewhat regular which tells me that it is recurring at some point even though it happens on different layers.
-
Oh man... now I get it
-
Well I think this would even beat S3D's custom supports...
-
@rreh: Das Problem wurde behoben und wird mit dem nächsten Firmwareupdate verteilt.
-
Hast du ein Foto vom schlechten Druckergebnis und vom Modell? Falls niemand ein fertiges Profil hat, könnten wir das Standardprofil zusammen verbessern.
-
I did select "Custom printer".

Hi,
Sometimes Cura creates way more support than a model needs because some overhangs further up the model trigger it. One could play with the "support overhang angle" but that might not always be optimal.
I have this following case:
The image at the top shows the extra support that I don't need.
The second image shows my solution to it - create a box and assign it with "per object settings" the "support mesh" setting. Also enable support for the box and disable support for the main object (the model is the ASP Explorer from the game Elite Dangerous).
The third image shows the layer view where there is only support merged into the main model where the box was before.
This is great and works perfectly. But I was wondering if it could be automated by Cura. Like an option to define the portion of the object where the bottom is located and then cut the model there, duplicate it and enlarge that bottom part and define it as support mesh. Kinde like what I did with the "support box" but with a thickened version of the bottom part of the model.
What do you think?

Ja schon, so wie du den Startvorgang beschrieben hast, dann sieht es so aus dass dieser nicht ausgeführt wird. Steht es in der .gcode Datei auch drin?
-
Das heisst der Start-Gcode wird nicht ausgeführt. Hm, keine Ahnung was da los ist. Vielleicht kann ein UMO+ Besitzer was dazu sagen.
-
Nein, ganz normales PLA verwendet. "Das Filament" heisst die Marke.
Lade einfach das Projekt in Cura 2.4, dann kannst du sehen welche Einstellungen ich gemacht habe. Bin vom "fast" profil ausgegangen und habe die Layerhöhe sowie an der Geschwindigkeit noch etwas geändert.

Ok habs gedruckt.

Nice work! Do you have a parts list or some detailed instructions?
-
Hi, and welcome to the forums.
I never tried the plugin with raft but I think this might be the problem. Try to print a simple object without raft and validate your idea about pausing at the right layer height.
-
Maybe it would be an idea to try to fix your problems with Ninjaflex? I bet there are some people around here who have successfully printed with it on the UM2. Speaking of which - do you have the Ultimaker 2 or the Ultimaker 2+? It makes a difference since the feeder was changed in the upgraded model which helps when printing with flexible materials.
Warum aktiviert der UM3 den 2. Extruder, obwohl Support nicht enabled ist?

So weit ich weiss ist das ein Bug in Cura und wird mit der nächsten Version hoffentlich behoben sein.
