    carbon PTEG won't budge, tried plugging back into the printer but hanging and the temp on matter control was very off so it would not heat

    If you can't run the heater core to heat it up and get it out you can try heating it in a convection oven.
    Get it to between 450-500 F for a 20 minute spell. (you will need to remove the thermistor and heater core to go that route)

    If you are brave take propane to it, but be careful not to use oxygen, just the MAPP gas (too hot can melt the brass).

    Here is an assembly diagram with parts called out. The E3D has all the same "bits" as a hexagon so you can see what they are called. The heater core is sometimes called the heater cartridge:

    Set screws (tiny allen ones) generally hold those parts into the heater block so ... loosen the set screws and pull them out of the block.

    Put it in a pie plate or metal pan you will be fine :) If you can angle it in the pan* it will all run out as it melts.
    Had to do this myself on another printer (HE280 hotend)... not fun, but doable.

    *I used aluminum foil to prop it up

    I originally bought a small convection oven to experiment with drying wet filament (cheap enough at Walmart) but ended up using it to clean out a gummed up hotend on the delta printer we have.

    Well After the oven thing did seem to work, after I burned my thumb lol. Unfortunately I lost a grub screw, so I just ordered 2 new one extruders from the robo store. I was going to anyway, but it would have been nice to print today. oh well.
