Is your feature request related to a problem?

When using materials that don't stick to each other (such as PLA with PETG), the wipe/purge tower fouls up.

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

Individual wipe/purge towers for each filament/toolhead, or wipe/purge towers per filament type.

Describe alternatives you've considered

1] I've tried turning off the purge tower, and this leads to wisps of dissimilar filament fouling the print.
2] I've tried both turning off the purge tower and using a custom object to simulate a per-filament wipe/purge tower. This almost works, but the print ordering sometimes goes to the object I'm printing first, and the simulated wipe/purge tower second, defeating the purpose.

Additional context

Please create an option to have per-toolhead or per-filament type wipe towers.

Do you mean that when using different types of filament, the printing quality of the wipe tower was poor, which led to the final failure of the printing process? In our future version, we will optimize the wipe tower and add filament_adhesiveness_category parameter. However, we will not create an individual wipe tower for per-toolhead, as this would occupy more printable space.
