Is this a new feature request?

Project File (.3MF) where problem occurs

Upload a PrusaSlicer Project File (.3MF) (Plater -> Export plate as 3MF for Slic3r PE 1.41.2 and older, File -> Save / Save Project for PrusaSlicer, Slic3r PE 1.42.0-alpha and newer)
Images (PNG, GIF, JPEG), PDFs or text files could be drag & dropped to the issue directly, while all other files need to be zipped first (.zip, .gz)

Please, search the tracker before filing a new one issue. Closing.

Thanks. Would it make sense not to display this in the code preview?

[lukasmatena]

It would stop these issue reports from coming, but I don't think it's the correct solution. The ramming extrusions that you see there are also on the wipe tower. It would not be consistent to only hide some of them. Not to mention they are extrusions like any other.

I think that the preview should show what the printer will do, as exactly as possible. Hiding parts of it would also make testing and debugging of the software more difficult.

As that material DOES get extruded, it should be previewed, I agree. I wonder if the MMU Handbook should be updated to include the FAQ entry, as it is somewhat disconcerting to see the extruder extruding in mid-air.
