Hot plastic. My extruder was running on the hot side, Nophead suggested this was due to the difference between the internal and external temperatures and he was spot on. Whilst I had originally constructed my Thermistor lookup table using a temperature probe clipped to the outside of the nozzle the inside was running a good 40 to 50 Deg C hotter. The problem is fixed now and a new thermistor table is in place all with the help of an Arduino based tool to help the process along.
