So.. I had the silicone sock mounted improperly for 35+ print hours (all done within a couple days), the sock melted onto the nozzle and now it’s glued the nozzle in place. Has anyone encountered similar or know how to remove the nozzle?

It sounds like the silicone sock may have fused to the nozzle due to the heat. To remove it, you can try heating the nozzle to a high temperature to soften the silicone and carefully removing it using pliers or a wrench. Be sure to exercise caution when working with hot components. If the sock is difficult to remove, it may be best to replace the entire hotend assembly.

How hot did you print? It should not do that

Have you used black filament before

I put my finger in and a chunk came out, I’m really sure it’s the sock

Is it worth trying to disassemble the head to get the hotend assembly out

Well its a quick change system designed for easy nozzle changes🤷 so if you feel the need to go ahead.

The nozzle can’t be removed, it’s almost cemented in place, maybe I could heat the hotend to 250 or so and then try to remove it with a tool or a good glove?

100ºC is probably enough

#

Turn the printer off before removing, no clue what the A1 does when the nozzle is removed while heating

Ok, will try

Worked! Nozzle removed, heated it to 110 and pulled it out with some tweezers, nozzle is covered and it feels like it’s probably filament, this probably needs to be cleaned up, should I go ahead and search how to clean nozzles and apply that to both the nozzle and the hotend assembly?
