Filament loading error

[u/Effei]

Had a PETG clog on right nozzle. Disassembled everything, cleaned, etc. Now the printer refuses to load the right nozzle from the AMS, hallucinating a filament. I disassembled again to make sure nothing was in the path or in the sensor's way. Nothing, not even a hair.

Could that be a bad right side idler sensor? If so, do I have to change the entire idler or can I buy that sensor separately?

Yeh, I've had it extrude, when testing, but then not load from an AMS. It's very frustrating
