With an idling Cura 2.7 and a connected printer printing stand-alone prints from USB key. the memory of Cura seems to increase over time. Can anybody confirm similar observations?

The OP asks for material profiles in the firmware, not Cura profiles.
And yes, it asks for override of the material if you sliced with a material different than currently loaded in the machine. But you are not able to load materials that are not Ultimaker branded ones. In that case you need to select material close to the one you are loading. E.g. choose nylon when you load POM, choose CPE when you load NGEN, choose ABS or CPE when you load PETG, etc.

Switch the core or material of the second extruder. You probably have not-pva & bb-04 nozzle selected there.
Actually I had, but removing it, assigning an other core and material and switching back did the trick! Like I said, not performing up to par. But this fixes my problem, thank you for your help.

How to reset the print profiles / material profiles.
By deleting the Cura folder in ~\Appdata and reinstalling Cura, I do not get the profiles back I used to have in older Cura versions. The Ultimaker PLA filaments came with 3 profiles: fine, normal and draft, I now only see fine. What happened with the rest?
P.S.: I know that the material/print profile section in not performing up to par, but I just can't understand where all the default print profiles have gone to. I ran into a lot of problems when creating non-Ultimaker filament materials in Cura. E.g. the print profiles for custom materials are not "adhering" to the custom material you created. I already reported this.

Somehow I posted a reply, but that does not show...
So here we go again... A little shorter now, sorry for that.
Delrin is POM. I use Nylon for loading. I adapted the profile to a lower temperature, lower speed and lower or no fan speed.
I have not tried it with PVA, I don't know if it is similar to nylon which does work with PVA.
-
AFAIK that is not possible, just load the material into the UM3 with a similar material profile. In Cura you can create other materials and hopefully a custom print profile (bearly as it is bugged), up to now you are required to fill out every option yourself each time you slice a model. The print will use this material then when printing. Since 2.6.2 I get a message just before printing that I'm not printing in e.g. nylon, but you can skip that as I have the sliced model setup to print POM. I have not tried 2.7 yet, so I don't know if the material and print profile bugs are fixed. I haven't had the time to look it up in the code myself.

I have not used this for two versions, so I am sure you caught a bug.
Let's hope the devs pick it up. I master many programming languages but Python is not among them yet (coarse is planned for next year). I already got the sources from Git, if I find some time I will look into it.
Thanks for your posts to make clear that it is probably a "feature" in the code rather than me failing to understand adding profiles.

I am not sure I follow the last comment about things not listed for the new material. I have material profiles for all my specialty filaments (T-Glase, Ninjaflex, etc) and can choose those materials in the drop down menu just like the Preset materials that come with Cura.
My materials also do find their way to the material list, but once I selected a material I cannot select any profile for it, the print profile list is empty. When I create my own print profiles (save and name them), they do not show up in the Preferences -> Profiles list box.
I also make sure I export my materials and print profiles as you can really clutter up that menu system. So, I load and remove as needed.
Good tip! I already had to redo all my materials (luckily only 2 PETG and 1 POM profile) when I upgraded from 2.5 to 2.6.2, as everything was lost.

Many thanks for these steps!
I'm not new to computers and develop software for my profession. Math co-processors, that was a fun time, takes me back at least 20 years if not longer. You (as I) were lucky ones to have 640 kB memory, then at least we could copy a floppy disk in one pass
opposed to the people with 512 kB which was very common at first. For the youngsters, a floppy was a flexible removable harddisk I follow you up to step 3 as that is exactly what I did. But, in step 3 when I have this new material, it just does not show the profiles of the parent material (OK can live with that) but when I save my own profiles the just are not listed for this new material, that is what is bothering me.
-
This does not explain how I can get print profiles for custom materials. Please explain or link to an explanation. E.g. should you un-link to the material you have derived your custom material from or not? Any help on this is very welcome!
-
Not that I know of, I'm really struggling to get materials in Cura (consistently that is) and accompanying printing profiles (for my UM3e). The whole material definition section appears to be affected by some unwanted features.
E.g. when I want a custom material like PETG I copy the CPE material from Ultimaker and change the vendor/brand and type and adjust only a few parameters like temp and fan speed (more is not possible in the GUI). Note that I un-link the material from it's parent it is derived from. When you save this the file is not renamed to your chosen brand and type, but are still listed as Ultimaker CPE! Hmmm... OK it is just a name, but clear is something else...
Then the following happens with that selected material if you want to use a printing profile, they are gone! OK, no problem lets make some of our own! I export a CPE profile e.g. "Fast", and import this back with the new material active. What happens, no print profile pops up in the list... Well that's strange, let's go back to the CPE material and surprised to now see 2 "Fast" profiles... It imported perfectly into the WRONG material... OK nothing lost I can live with that, I'll just make my own. So, back to my new material do some changes I like to call it a "Fine" print profile and save it to see that it does not come up in the list (but it does show up in the combobox as a name, when you pull down the combobox it is NOT there).
This has been done in Cura 2.6. I would love to hear from the developers what I'm doing wrong here, as the default materials and print profiles are awesome, I just want to create similar profiles for my own materials like PETG (close to CPE) and POM (close to Nylon).
And I forgot to say that once the material has been created it tends to miraculously change when you open it a few days later, but I cannot reproduce this.

Cura is not clear in that respect, I consider the whole material and profile settings very buggy.
When defining custom materials there are not much options to store while when stored the values also tend to change between sessions or Cura versions.

Same problem here, brand new UM3e out of the box, print number 2 gave me the same error at about 10 % of the print (first print was the x/y calibration). Also a combination of PLA and PVA. Rather disappointing for such a high end printer. Luckily I live in the Netherlands. Let's see how their support is.

Cura 2.7 memory leak?

Thanks guys, but the next question arises: "When can we expect Cura 3.0?", and: "Does it have a new material model for custom material specification?"
Edit: Just found out that it is in two weeks time!
