Thanks to everyone's help I was able to get everything removed from the machine. There was a piece of filament in the top of the barrel which I had to cut off with a razor blade. It is a very tight fit even for thin blade. Once the filament was cut it took a bit of effort but the heater assembly cam...

Thank you very much! I have everything exposed but the barrel won't budge. I thought I had gotten all the filament out but there must be a piece remaining. I have every other tool in the world but at this moment I can't find a razor blade

Thanks again.

The assembly instructions for the barrel and nozzle are clear enough but how do you remove the hot end assembly from the machine. It is probably very simple but I am a bit of a bull and don't want to break it.
Thanks for your help.
