Hi guys,

I am facing an issue I dont understand.

I am using my ender 3 with stock head and the original metal bowden feeder.
I am calibrating before each print with the CR touch and using octoprint on the raspi zero 2. My Slicer is Cura.

I only print with PETG and I have tried many brands.

My issue is, that the walls and support prints fine, but the infill has underextrusion issues and I am hearing this clicking sound like if the filament being retracted when the nozzle is clogged.

I replaced the whole print head and the nozzle and the issue remained.

Any idea whats going on?

Why do I experience the issue only with the infill?

I was thinking maybe its due to the feeder flattening my filament during retraction, but the thing is, that once the printer continues with the wall everything works fine.

Thanks in advance!
