Most of these issues are coming from the graphics driver. I cannot say exactly why or which driver solves the problem, because I am a Mac user, but I read a lot about these issues and it was always the graphics driver.
So even if you think you are up2date with your driver, check if there is another driver or option.

Yes, I am referring to the image size and even if you think it has or should be 24mm there could be a problem when exporting the object as STL and importing into Cura. I have seen some STLs which have in Cura only 1mm or less and I was zooming in extremely to see the object. Something I need to scale up the object to 1000% to have in a proper size.
It depends on the CAD software you use or the designer has used. Sometimes they use different units (inches, mm) and then after export and import you get these very small objects in Cura.
There is also an option in Cura to scale up very small object during the import, but it never worked for me. You could also try to set the option in the preferences to "select the object after import" then you don't have to search for the object after import and you can go directly to the scale tool on the left and try what happens after you scale up it something bigger.

I think if you don't print regularly Ninaflex or even softer materials, then you should be fine with the default feeders.
-
Yes, it could help maybe with softer materials, but I don't know it. The softest material, I have ever used was TPU and this was no problem, also not for the UM3 feeder.
On the other hand, you would also have the e steps problem when changing the feeder. You can set the e steps with ssh into the printer and change the values there, but you have to do it everytime you make an update.
-
I see no need to update the feeders from the S5 because they are great and a big upgrade from the UM3.
The S5 feeder gears are already hardened to print with abrasive materials and the lever to fully open the feeder tension is also a big advantage to the UM3 feeder.
What advantages do you expect to use the Bondtech on the S5?

Looks not so good, but be happy that nothing more happened.

21 minutes ago, Kevig said:
i noticed:
- rotating the object 90 degrees seems to solve the problem
(did not try smaller rotations or 180 rotation)
- re-clising changed the location of the shift, not the ax
- the problem occeurs often the layer before or after a change in design
(ie i had a keychain with cutout characters, the layer after the characters shifted or with a fanduct exactly at the end of a internal screw hole)You have a problem with your printer hardware, loose belt, loose pulley or something like that. Check the tension of your belts, check if the belt itself is ok. I am sure you have some play on one axle and due to a direction change, the layer will be slightly shifted a little bit.
-
We cannot predict what's the problem, so post more information and upload the Cura project file.
-
Maybe your object is so small that you cannot see it? I have this from time to time when loading STL files from someone else.
-
For me, it looks like that the distance between bed and nozzle it to high and therefore the material will not be squished enough into the bed. Have you leveled your bed correctly?
What are your other settings? Line Width, Nozzle size, Layer Height, First layer Height? Would be much easier if you would post your Cura project here.
Do you see the problem already in the layer view in Cura?

Ich habe noch nie die Zeit gemessen, aber träge ist das ganze schon auch bei mir, aber nicht so schlimm, dass es besonders störend wäre. Vielleicht habe mich auch schon einfach daran gewöhnt 🙂

In the last months I tried several storage solutions for my the print cores, but either they didn't fit or it was not practical. Most storage solutions have the problem, that they are open and dust can easily get into the core which is not good at all.
Some days ago I had an idea, to put my print cores in an Ikea Skadis container mounted on my pegboard. Inside this container, I designed a print core holder which is based on @ultiarjan version and holds 3 cores per container.
Here are some pictures:
The cores are now stored in a safe place, protected from dust and can be easily accessed.

And finally, the redesigned version which fits into the Skadis container:

Das muss nicht unbedingt helfen, denn ich hatte auch mit High Sierra keinerlei Probleme mit damals 3.4 oder 3.51 (wenn ich mich jetzt nicht irre). Cura 3.6 habe ich unter 10.13 nicht mehr versucht, weil da schon alle auf 10.14 upgedatet waren.
Irgendwer hat hier auch berichtet, dass er mit einem aktuellen Macbook Pro 2018 und Mojave Performance Probleme hat.
Was ich immer noch nicht verstehe, warum es bei manchen geht und bei anderen wieder nicht. Unter Windows lasse ich mir das noch einreden, da gibt es viele Komponenten (Graifkkarten) die unterschiedlich sein können, aber gerade beim Mac ist das eigentlich kein wirkliches Thema.
-
Warum es auf manchen Macs zu solchen Problemen kommt, ist mir auch ein Rätsel. Man vermutet irgend eine Library die da mit hineinspielt, das allerdings eher auf noch älteren Versionen von MacOS.
Bei mir läuft Cura 3.6 und 4.0 beta ohne Probleme auf einem iMac und 2 Macbook Pros jeweils mit dem aktuellen Mojave.

I will give it a try soon. Maybe a mosquito net could also work, let's see what I find. But you are right those wedding veils are super thin and maybe the best to print such things on.
-
Amazing 🙂
Have you used a special fabric? I think it must be very thin?

That's fine!
And a happy new year 🙂

Try to set the minimum layer time to something higher, maybe 10sec and print slower.
A 5mm part is really small and as you said, the previous layers could not cool down enough.
It can also help if you print 2 or 3 parts at once.
-
Looks good, please give us some more details about how to print on fabric. I will try it also next year.

Ok I see, I also tried to add a UM2+ to my Cura and I have the same behavior. It is strange because with my UM2Go I can choose from several profiles, but the UM2 has no dropdown to select the nozzle.
I am out of ideas, but I am sure there is a way. Here are a lot of users with a UM2+ so, let's wait if some else jumps in with a hint.
-
You should have more than one profile, if not then there is something wrong.
Do you have more profiles if you choose the 0.4 nozzle?
-
Puh, auf Anhieb wüsste ich jetzt nichts, aber das muss nicht heissen, dass es nichts gibt. Schau einmal ob du über die Suche etwas findest.
-
Der Aufwand hält sich in Grenzen, der Druckkopf ist ja schon komplett zusammengebaut. Aber ob das in den Original passt bzw. ohne weitere Umbauten kann ich dir nicht beantworten.

Warum diese Teile nicht wieder bei iGo3D anfragen?
Habe mit iGo eigentlich nur gute Erfahrungen gemacht.

You find the option to turn off the auto drop in the preferences of Cura.
