Nozzle not coming off on Taz 6

So recently my printer got a clog I tried doing cold pulls I put a guitar string though none unclogged my printer so I decided to change the nozzle. After several attempts to remove the nozzle none worked. Does anyone know how I can fix this?

Can you describe the toolhead you are using? Is it the stock toolhead or a newer one? There are options to clear that clog that don’t require changing the nozzle, but it greatly depends on the toolhead.

I believe it is the stock I haven’t changed it science I bought it


(Here I have one of the fans removed)

Not sure what filament is in there now, but I would first heat it to something high like 280, open the filament tensioner, and pry a 2.5mm hex driver into the filament path. This should push out the blockage, assuming it’s just filament. Try that first and report back.

I have been using petg for all my prints

I also just did a cold pull to check my nozzle it is looking a little weird

Dumb question, but is your heat break fan working? The fan in the middle. I find cold pulls are next to impossible to do with 2.85, it just breaks in the middle.

Hi yes after a bit more trying I was able to take off the old nozzle and now the printer is working fine. Thank you for all the help!
