First time poster, did some digging but couldn't find advice specific to this problem. Had a print going and all was well, then... this:

Obviously, I can't get the thermocoupler out as I don't have access to the set screws. is my best option to cut the wires and just get a new hotend and thermo assembly?

Thanks in advance

you can use a heat gun to soften the plastic, then just peel it off the hotend.

I had once bigger blob than this after failed print over night for full bed size object. I didnt have the heat gun, so I just used another hotend to melt (heat up to around 150c) by pressing it into the plastic ball till it reach the metal hotend inside. Wait it to get cool down for a 30seconds, then use cutter pliers to break it, will be very easy to take out chunk of plastic this way rather than melt them as it will be difficult to remove cleanly if plastic become soften.
