How to reproduce

Try to print with high+low temp filaments on a single exturder multi material printer

Actual results

Unable to print multiple filaments which have large temperature differences together. Otherwise, the extruder and nozzle may be blocked or damaged during printing.

Expected results

I found the error message to be misleading.

Anything else?

I found the error message to be misleading.

I spent longer than I'd like to admit tweaking temperatures for ABS and PLA, even outright copy/pasting values to make them identical trying to silence this issue. It was only upon some digging around on google and coming accross the bambu studios issue above that I discovered that the error wasn't from temperatures, but rather a filament type incompatibilty list. Maybe just adding types after Unable to print multiple filament would be enough to make that clearer?

Maybe just adding `types` after `Unable to print multiple filament` would be enough to make that clearer?
