Draft shield filament use wrong for dual extrusion

[mobilinkd]

Is there an existing issue for this problem?

• I have searched the existing issues

OrcaSlicer Version

2.3.0-dev (2025-01-08)

Operating System (OS)

Linux

OS Version

Fedora 41

Additional system information

When slicing two models each using different filament, the filament used for the draft shield alternates between the two, even when printing by layer, per model.

This is a problem when the filament types are incompatible and do not adhere to one another well.

Printer

Highly Custom Flashforge Creator X with SKR Pro 1.1

How to reproduce

1. Select a dual extruder machine profile.
2. Select a different material for each extruder (select contrasting colors to see in preview)
3. Add two cubes to the project.
4. In the object view, set the first object to the first extruder, second object to second extruder.
5. Enable skirt, per object, and enable draft shield.
6. Slice project.
7. View the draft shield layers by filament type.
8. The filament type alternates for each object's draft shield.

Actual results

The filament type alternates for each object's draft shield.

Expected results

The filament type used for the draft shield should match the object type.

Anything else?

This it the result when printing a PLA part and a PETG part. I was attempting to use the draft shield as an ooze shield. The layers of the draft shield did not adhere well.

@vovodroid would you mind taking a look at this one?

Well, I don't use dial extruder. May be I''l check it when I have time.
