Hi Reece
I think we've emailed each other quite a few times... and I think you're still having the same problem. The temperature of the extrusion is far too hot; it's burning the plastic as it prints. The filament won't be extruded, it'll be running out of the hot end like water. I can see it sets the temperature at 180C in the gcode. Can you remind me where we got to with trying to sort out the temperature problem? I've changed computers since the last time you emailed, and don't have the history of our conversation.
Also, if you can post the response to M503, and maybe some pictures of your hot end, that may help.
