My MMU3 has about 3300 filament changes. And yesterday it started failing to load filament. Like, almost every load failed. Tonight, the printer threw up an error screen about checking the extruder's "main plate". I opened up the extruder, and goodness, that's a lot of debris.

The main plate is worn out too. Apparently all that fun glow-in-the-dark filament accelerates wear.
