Long story short:
Try to print ( P1S) Bambu PLA from my AMS2 pro. After 4h of print got the message that the engine from the feeder (in the AMS) is overcharged. Try to restart… 1,2,3 times. No joy. finally got the message extruder blocked. OK no biggie quick fix. Restart no? Nope, still no joy. Nozzle clogged? OK let’s fix that, it’s simple to do. But why not put a brand new (0.4) in and try. Still no succes :-(. Finally found the problem : the filament had a part where the diameter was way off ! It was 2.25mm instead of 1.75mm. Of course the printer was unable to feed it to the system/nozzle 
. A bit dissapointed in bambu fillament… Never had a problem with the cheap ones.
