Ironing not applied on top of first part of a two-materials print on the Prusa XL
Hello,
I wanted to print a smooth sheet of PLA to print very tiny PETG objects over it. I wanted to have ironing of this PLA sheet before printing the PETG. Ironing is desactivated for the global print but activated for the PLA sheet (designed as a box within PrusaSlicer itself). However the ironing doesn't happen and the PETG part is printed directly after completion of the PLA part.
Is it a bug?
Project attached.

You are zipping it up ? The forum only allows a limited number of formats, 3mf is not one of them. You need to zip up most files before attaching them.

Still no file. Lets try attaching a random file zipped up.

Well that looks like it worked.

Attach file with the Choose File button is what I used to attach the zip file above.
I am using Chrome too but I've used Edge before too. Not that theres much difference between them.

I suspect the issue with my file is its name containing accented characters despite the .zip file's name being without. Let's have a try...

OK. this confirms the issue: even within a .zip file the .3mf file name should be without accented character. This is what you get when all the foundations of computing have been invented in the USA, a country where accents are unknown...

I only ever use normal a-z and 0-9 characters for filenames. Especially if they are for printers or similar embedded systems.
Is the test_upload zip your actual problem file ?

Yes, this is the right file.

Its quite simple why its not ironing. Ironing only applies to top surfaces. Your bottom object is only a single layer thick so its just Solid Infill (purple in colour on the type key). As that is what the bottom layer is printed as. It needs to be actual top fill (Red) for ironing to be applied.
You could argue that its the top layer so why isn't it treating it as top. Well First layer settings have priority over that as getting it to stick to the print bed is more important. Also I'm not sure how practical it is to iron a first layer anyway, for me they are always smooth if my live z distance is set correctly. So no ironing required.
Either make that bottom part thicker to print as 2 layers or change your layer heights such that the first layer and your normal other layers adds up to match the 0.28mm height you have. Something like setting the first layer height to 0.1 for example allows it to have 2 layers.

OK, thank you for the explanation @Neophyl!
