Nozzle completely stripped, now what?

The flimsy wrench that comes with the A20M bent trying to loosen the nozzle. I used a craftsman wrench. The brass stripped. Tried vice grips. Is the next resort a new heater block? Thoughts. It is not coming out.

Well, using a hardened steel allen wrench, the screw holding the heating block on stripped too. The factory overtightens and as a result I need a whole new head just trying to change a freaken nozzle.

You must heat the nozzle (190° approx) to be sure that plastic dont block it.
Trying to unscrew a cold nozzle can result in a crushed nozzle.

Bras tip need to be removed hot, not cold.
Use this tool after extruder is heated

Hi, for nozzle replacement,
you can try heating it up

You can refer to the video for specific operations:
