MK3S MMU2S won't load filament anymore

HI,

 

I have used my MK3S with MMU2S  a lot and now it starts to give me a headache, I start a print by loading filament in port 1, Nice dry Prusa black PETG. The pre heat the nozzle and bed and start the print. Settings default Prusa PETG in PrusaSlicer.

The filament goes to the nozzle and I can feel and see the filament comes in between the gears and the sensor is triggered on and off (Support Sensor IR 0>1>0>1) and filament flows out the nozzle. like the filament diameter isn't right.

Then it draws back the filament and loads it again, Repeats this a few times and there is building up quite a blob under the nozzle.

It looks like the sensor isn't triggered the whole time I checked it a few times and it does trigger like it should and the its back to 0 again.

Any help please?
