(fellow user who isn't using different nozzle sizes yet) Could you post a zipped 3mf file of an example setup that you want to work? It'll be interesting to see if a workaround can be built without disturbing my defaults. Cheers!
If you could have multiple wipe towers, where you assigned different sets of extruders to different towers this would also enhance multilateral printing. It would just be easer to have separate PETG and PLA towers than messing with the support structure of the tower and assigning an extruder to its exterior.
Adding support for multiple wipe towers would greatly improve print quality and make more complex multi-material prints possible. This would be especially useful for printing with different nozzle sizes or materials that don’t mix well, like PETG and PLA.
Here’s an example to consider:
Material Compatibility: Separate wipe towers would allow materials with different properties, such as PETG and PLA, to be used without issues. When combined in one wipe tower, PETG can get pulled out or dislodged, causing print problems.
Better Tower Placement: As shown in the example, placing different wipe towers on opposite sides (e.g., yellow on the left and black on the right) helps prevent filament strings from crossing into the wrong material or color.
Less Color Contamination: In multicolor prints, having separate wipe towers lowers the risk of color contamination, like stray blobs messing up the print’s look.
Improved Recycling: Keeping colors and materials in their own towers keeps them pure, making them easier to recycle and reuse.
While multiple wipe towers do use more material, the benefits of fewer print failures, less cleanup, and better overall print quality often outweigh the extra cost. In many cases, having a perfect print saves more time and money than the additional material used.
It's not currently possible to use multiple nozzle diameters (say 0.4, 0.6) and multiple materials with wipe towers in the same print with Prusa XL 5 toolthead version.
PrusaSlicer notifies that wipe tower is not supported in this setup.
One solution could be to allow multiple wipe towers. One wipe tower where 0.4 tools are wiped and another wipe tower where 0.6 tools would be wiped. This would at least allow to use wipe tower with multiple tools setup. And / or one wipe tower per material.
