On some materials with higher viscosity the z hop literally pulls the filament out of the hotend, especially with larger nozzle diameters. In such cases I recommend to switch off the z hop. I do this for instance with UM Nylon and get significant better results without the z hop.

Don't forget to check the print head cable, i.e. the cable going from the print head to the board.

You mean using a few GB for a simple small STL is not normal?
The situation should get better in 6 days. -
@Oj00, may I ask which of the two bearings in the printhead lost a ball?

I can't say much about lifetime of the UM3 printcore teflon inliner as I did not yet had to change a core due to degradation. However, I might not be the one with the most print hours on his UM3 and I do not print abrasive material.
Printing with advanced materials like PC, which I like a lot, gives you certainly a harder job at cleaning the cores on the outside (nozzle) and makes also regular cold pulls a bit more significant. The silicon pad @sandervg wrote about are indeed done relatively fast when printing materials at 250-260°C. Of course you can relatively easy and inexpensively replace them but at some point a pad from a more heat resistant material would be welcome...

firmware version?

Do you have the same effect when you put it into the other slot?
-
Ah - what a pity. So I guess there is no reasonable possibility to get a feedback from the GPU if it has drawn "purple-ish with a white sort-of X-ray vibe" or not. So one would have to implement a control algorithm for the model then.
On the other hand one can just make oneself used to check the x-ray vision before print.

Ja, gibt es. Nimm doch dazu bitte Kontakt mit Deinem Reseller auf. Der hat sie entweder an Lager oder kann sie Dir besorgen.
-
Well, a 3D printer could be made more intelligent, maybe just not for the same price.
I assume the x-ray view has some kind of drawing routine in which is decided to draw certain parts in red, right? This would have to be used as an output somehow to trigger a message as suggested by the OP.

Wegen der Reihenfolge: Da kommt ein Optimizer-code in der nächsten Cura Version zum Einsatz. Der wird die Perimeter Linien optimieren, aber vorerst noch keine Mischung von Perimeter und Infill zulassen. Ist aber für die Zukunft auch angedacht.

Gibt's schon, wenn Du auf Aliexpress schaust. Da weiss man halt nie so genau was man bekommt.
Ansonsten ist es natürlich eine Frage der Verbreitung eines Druckers. Der Ultimaker 2+ ist natürlich schon deutlich weiter verbreitet als der UMO+.
-
Do you happen to have a short video of that awful noise?
-
I recommend to newbies to check the Cura ressource pages on the Ultimaker website, in your case especially this one here: https://ultimaker.com/en/resources/49701-dual-extrusion

Yes, for the time being one should always keep a copy of the written text in the clipboard or somewhere else before hitting the post button. I understand your anger, had the same problem a few times recently.

Well, UM does the minical test print that comes with the printer indeed with the included bb core. Usually they clean it before shipping. But it should just be black PLA, so very easy to remove by heating the core up to 150 deg and wipe it with a (thick enough) piece of cloth.

Diagnosis will stay in, even in release until further notice. It helps with analyzing problems more quickly. Maybe it's an idea to have it enabled only when Developer mode is switched on?
That would make more sense to me, similar with Android - flip a switch and you can debug and diagnose more.
Fully support that idea!
edit: to be more precise, things like the nfc reader test are useful to the standard user as well while the stress tests are usually not needed. So not the whole diagnosis menu would have to disappear in non-dev mode.
-
It's quite easy to my experience to rotate the wheel a bit while pushing at and to screw it up like that. Maybe I'm just more clumsy than average.
May I ask what the need is to remove it? Does it bother there?
-
So if you screw the z offset calibration up you have to do the whole manual bed leveling in future as a punishment, do I get this right?
edit: I would rather suggest to drop the z offset at the manual bed levelling wizard and add an input request at the z calibration if the user wants to do a manual bed leveling before the z offset calibration (continue-skip-selection). To me it sounds not logical to have the xy offset calibration in the calibration menu and the z offset as part of the manual bed leveling procedure in the build plate menu.
edit2: I hope one of the minor bugfixes is removing those stress tests from the diagnosis menu which are imho something that is not needed in an end user firmware. It's ok to have them in test versions of course.

Maybe some sanding?

Du kannst eine UM2+ Düse verwenden wenn Du einen eigenen Fanduct druckst der weniger weit runter reicht. Stelle einfach sicher dass Düse und Messinggewinde von oben sich sicher innerhalb des Alublocks berühren.
-
You cannot really hide it with a radial symmetrical part. You may want to try to print it at a lower temperature. This will lead to less leakage during the time it stands still while changing the z height.

This should answer the question: https://ultimaker.com/en/resources/44677-maximum-build-volume-ultimaker-2-plus-ultimaker-3

Heating the plate quicker?

I put a cardboard onto the plate while preheating. This reduces radiation losses to almost zero and heating up is a bit quicker.
