I am currently using Cura 5.0.0 as slicer. Unfortunately Cura does not show any logo for the Sovol SV04 on the respective buildplate. Therefore, I have created five logos:
The STL files should be copied to the following folder:
Windows > Program Files > Ultimaker Cura 5.0.0 > share > cura > resources > meshes
Additionally the five different Sovol SV04 ".def.json" files (in the definitions folder) have to be changed; this can be done e.g. with Notepad++.
After starting Cura you should then see the respective buildplate with the desired logo.
The author marked this model as their own original creation.
