[Feature Request] improvement of the last multi-material carrier layer under the first Support Interface layer
It's about a function that was implemented better in Bambu Studio than in Prusa Slicer 2.7.1 Printer: Prusa XL5 Scenario: Print object made of PLA (extruder 1) PLA support structure (extruder 1) Support Interface layer (extruder 2) with PETG
Top contact Z distance: 0 (soluble) Pattern: Rectilinear Pattern space: 0mm Topinterface layer: same as top
In the Prusa Slicer, a support structure made of PLA with a rectilinear pattern is printed in the same way up to the interface layer. Then 3 Inteface PETG layers are printed. Here, the first inteface layer is printed in PETG and has poor adhesion on PLA. There is no option to change this.
see picture 1 , first interface layer in PETG (Prusa Slicer 2.7.1)
Bambu Studio: In Bambu Studio, under the first interface layer in PETG, the last layer of the support structure is printed like an interface layer, but in the material of the support structure (PLA) and only then are the other real interface layers printed with PETG. This gives the first PETG interface layer more strength or adhesion and the other layers are printed more reliably. This is standard in Bambu Studio and cannot be changed.

Here, the last support layer is still printed in PLA and the following interface layer in PETG find a solid layer for better adhesion

Proposed solution for the Prusa Slicer: A good solution might be a selection option that allows you to choose whether you want to print a final support layer with extruder1 or extruder X or not at all.
Best regards,
This change is critical to making multi-material supports work - it just simply DOES NOT work (adhere) otherwise.
We need this to take full advantage of the XL multi-material handling capabilities
It would be great if the number of interface layers could be freely selected and the extruder could be chosen separately for each interface layer.
This would also make complex support interface structures conceivable, e.g. three different materials, with the third filament as a special bonding layer for the other interface layers.
UP! Please, it would be awesome! Actually it‘s useless!!! The current multi-material possibilities are clearly behind the hardware in terms of software. Unfortunately, the Bambu Studio is slowly outperforming the Prusaslicer.
Reminder: I still have hope, I'm not giving up yet.
Please make the Prusa XL the best multi-material printer on the market
It is so easy for them to implement this as it is already available in derivative slicers. All they have to do is merge the changes.
This issue combined with #12688 are critical for excellent support interface layer success.
