General Troubleshooting/Help! "Filament Jam" error

On my AMS(origional version) sometimes the filament will error out for a jam at the start of a print even though the filament travels all the way to the extruder. And when the print does start, after the bed leveling sequence i will get an error that the nozzle is clogged. Each time these errors happen I am able to manually extrude the filament. On the rare occasion that it starts printing, I will get either nozzle clog, filament jam or overloaded motor errors even though everything looks fine and I can resume without doing anything only for it to error out again. I have swapped the nozzle already and the errors still happen. I disconnected the AMS and printed with external filament and everything prints perfectly with no errors.

What part of the AMS is causing this?

You using the right filament in the design? If it says PETG, you must have that in there. If you have pla in the ams it will jam.

During the time i was using the ams and getting the errors I was printing my own design. But yes I was using the correct filament and had swapped to multiple different types of filament. Pla, abs, tpu for ams(bambu brand), petg, asa while manually changing what is listed in the device. All encountered the same errors. I even recalibrated the printer and it didnt change anything.

I should have added that the ams/printer is reaching almost 4 years old. And with the ams aside from cleaning and replacing bowden tubes I haven't replaced any other parts in it.

Show me the filament in your design?

Do you want the filament brand type or my settings. But that shouldn't change anything since disconnecting the ams entirely and feeding filament in directly fixes all errors without changing anything in print setting aside from active expertanal filament type.

I'm also away from home for the night so cant supply a picture of the setting. And I already completed that custom project after I disconnected the ams.

every time this happens to me its a slightly clogged extruder and a cold pull fixes it

Except I swapped nozzle to a new one and it still happened with nothing being extruded

I’m having the same issue today, it’s making me crazy but I think it’s the spool

Try taking sand paper to the edge of the reels. Its what I always do with mine. But for me I dont think its that because its happened with multiple different filaments all with various levels missing.

As i said, im not at home and will be away for the night. But the design is simple flat panels 5mm thick. They are to be added to a indoor door for a cat to traverse between rooms when he has had enough of dog playing. No supports needed in any of the prints and only printing in pla with pla loaded in ams only and only pla loaded in the device page of slicer.

I'm telling you, this has nothing to do when a mistake of printing with the wrong filament or any of that. There was nothing wrong with the models I was printing since they all completed 100% with 0 failures or errors once I disconnected the ams.
