CURA for Ultimaker 3+ Extended makes an unreadable file

Did you create an UM3+ Extended printer in Cura? Which version of Cura do you use?

If you use on of the new Cura versions (3.x), you could save your actual project as a .3mf file and attach it to this post so we can have a look.

There is no Ultimaker 3+ extended, I just used your naming without thinking - sorry.

I can't tell what went wrong here. When I load your project, a new printer is created (Ultimaker 3 extended) but the part can not be sliced (see screenshot). I assume something went wrong with the printer creation.


If you don't have other printers defined in Cura, I would suggest to remove the actual version and install Cura 3.4.1 again. Then create a new printer (Ultimaker 3 extended), drag your .stl file (scal it since it is tiny - I guess inch<->cm issue), set the material to ABS (if you really want to print with ABS) and slice again.


Btw. I saw that you also set to print with support with PVA - but the combination ABS/PVA is not supported. I disabled "support" in Cura with your project but the problem still persisted.
