Issue after long prints with ASA
This is the second time I have exactly the same problem: after having printed some parts with ASA using the PrusaSlicer standard preset (0.15mm ASA Prusament-0.4 nozzle). The filament get so jammed into the PTFE tube, that in the end, I have no other choice but destroying the PTFE tube to extract the filament.
I guess what happened is this: the printing was long (10h). I think there is probably a moment when the heat propagate so much into the PTFE tube that the filament become liquid into the tube (and not only to the nozzle). After cooling down, the ASA filament becomes actually weld to the PTFE and impossible to extract (even following the method proposed by Prusa's support).
What is annoying is that I can't see when I was wrong. I just used PrusaSlicer's preset as it is. Probably next time, I will consider mandatory to unload the filament after every long ASA printing, and before it cool down.
Let me know if you have some particular advices.
RE: Issue after long prints with ASA
I've printed with ASA lot and learned very quickly that it is best to remove the ASA filament when have you finished printing, it has a tendency to clog the hotend, at least that is my experience. It happened to me with the stock E3D and Mosquito hotend.

Many thanks to confirm what I foresaw about ASA, mvalkier.
