Support for Wipe Tower with specific support material ??
The problem: I want to print something using quite expensive filament. The model requires support. I want to print the support with some random PETG I've got lying around.
Printing without a wipe tower doesn't work, oozing results in much too little initial filament; also, drippy bits and pieces get dragged onto the model.
Printing with a wipe tower doesn't work either because, surprise, PrusaSlicer doesn't support that.
The Wipe Tower currently supports the non-soluble supports only if they are printed with the current extruder without triggering a tool change. (both support_material_extruder and support_material_interface_extruder need to be set to 0).
So what do I do? Wait for the Prusa people to fix this problem? Use a slicer that supports a wipe tower? Waste $$$ of expensive filament for my support?
RE: Support for Wipe Tower with specific support material ??
Sounds like something super specific that we'd need a (zipped) 3mf to poke at. It isn't complicated to set a single extruder as support, so it's probably some other setting you havent mentioned that doesn't play well with something else that's causing the limitations.
Otherwise to toss a few ideas: It wants a soluble support so just tick the box in filament settings to claim it as soluble even if it isnt; or maybe this is one of those print setups where you'd need a slicer fork to force-bypass current limitation flags.

Well, I'd assume that printing something of expensive filament with some less expensive support material would be far less "super specific" if it'd actually work and people knew about the fact that you can actually do it.
No, faking solubility of the support material won't fix this.
To reproduce:
- open slicer
- select multi-head XL
- add a sphere (as or anything else that'd need support) to the plate
- turn on "generate support material"
- turn on "enable wipe tower"
- set "support material extruder" to 2
- observe message telling you that you can't do that
- write Forum post to ask what to do next
RE: Support for Wipe Tower with specific support material ??
Use the "Soluble Full" Setting. There you can chose your support Extruder and it works with the wipe tower.
Don't use a wipe tower, wipe into fill, or a wipe object, instead.
Cheerio,

As @m-weiman said. See https://help.prusa3d.com/article/combining-materials-xl_498103
Whether applying a "soluble" profile to a non-soluble support filament makes much logical sense is of course debatable. But it works.

I went extra and even used 3 materials/tools and it slices fine.

@baconfase Could you please share your 3mf file so I can see what you did differently than me? I get that error message no matter what.
@diem I tried adding an object and marking it as "wipe object", but the slicer didn't send the support material's extruder to it.

If you'd just uploaded yours when I originally requested you'd already have your answers and specific to your circumstances. lol
Here are two default examples with 2 and 3 tools used: 23supportMaterial

RE: Support for Wipe Tower with specific support material ??
I had the same problem you just have to set the value under Support material "TOP contact Z distance" to 0 (solube) then you can select the extruder for support material without an error message
RE: Support for Wipe Tower with specific support material ??
Why not enable (as in, add the function for) multiple towers (one per extruder width)?
RE: Support for Wipe Tower with specific support material ??
If you set the interface distance to zero without using a soluble filament won't you have trouble detaching the support material?
RE: Support for Wipe Tower with specific support material ??
I couldn't find a wipe into fill setting. Does such a thing exist? How would you do the wipe object?
Don't use a wipe tower, wipe into fill, or a wipe object, instead.
Cheerio,
With several objects on the build sheet - select one for which colour/filament doesn't matter, right click > Wipe options - and set requirements in the pane on the right.
Cheerio,
RE: Support for Wipe Tower with specific support material ??
there are several filaments that don't stick to each other. IE: PLA and TPU or PLA and PETG for that matter.. and if you use one as a 0 interface support, it will allow a much better surface than using one with separation.
