I always microwave my pellets before AMNPS. Like maybe 30 seconds for a big handful. I have not had them go out since doing this, leaving the chip loading tube out a couple inches for a better draft per Todd's instructions for my MES30. That gives a continuous source of smoke. I find that my MES only produces fairly ateady smoke on higher temps, like around 180 and up.
I never nuke my wood pellets. Like Gary S I just take them out of the bag and place them in the AMNPS.
Also, the MES produces steady smoke during cold smokes. I don't even plug it in; I just use the AMNPS.
