    Does the brass nut come off the heat sink so you can clean out the micro jam if there is any?

    I cannot seem to take mine off.

    They come off, but are supposed to be put on and removed 'hot' (if you put them on cold then the thermal expansion differences between the brass nozzle and steel body can make them loose at temp).

    So my suggestion is:
    1) do it hot (extruder at printing temp or a bit above) I think I did mine at 250c (with the new volcano I have even done it hotter).
    2) use two wrenches. One to hold the heater block steady and the other to turn the brass nozzle. Do not stress the heat break ( the skinny part of the extrduer between the heater block and the heat sink) or it may break. Just be careful. I have swapped mine a fair amount.

    Thank you so much man, I didn't know I had to do it hot.
