RE: Temp. warning and white build up around nozzle

Hi Max, 

It's hard to say what went wrong, however 
You appear to have a buildup of filament between the heat block and the heatsink 

AS indicated by the red arrows above. 
This may result from a poorly fitted nozzle or a Blob of doom

this is likely to cause heat from the heater block, passing into the cooler heatsink, which could cause heating difficulties and poor printing 


Your extruder should be set up like this...  and definitely no plastic between the heat block and the finned heat sink

regards Joan

I try to make safe suggestions,You should understand the context and ensure you are happy that they are safe before attempting to apply my suggestions, what you do, is YOUR responsibility. Location Halifax UK

The white powder is normal for ASA. But as Joan indicates, the buildup between heater block and heat sink is not.
