Hi, I too am experiencing this issue. Can you please provide an update? Did the new flow sensor solve the problem? Thanks

Hello! I was having the same issue before untightening the Allen screw on the feeder, after untightening it 1-2 bars, I had a successful print on PLA/PHA. Hope that helps!

Hi
I have had the little connector on the back of the extruder work its way loose a couple of times which as I remember gave this error. More often though it has been the extruder wearing a groove (not always a big obvious groove) in the filament when retracting either lots of times in a small area or because the filament sticks in the core a bit. Also check your front fan is switching on at 40C nozzle temp.
Hope this helps

Hi Mrender,
Thanks for your reply and suggestions. I will check that definitely. For now, I have disabled flow sensor and both printer cores are printing fine so far. I have ordered a new flow sensor and new fan which will be replaced and test again.
With regards to the groove, is it possible to share any photos of the groove you are referring to ?
