I have an MES 30 analog with a PID controller so temp control is great. I got a 5x8 AMNPS and on the last hot smoke and on the two butts I have going now, I cannot keep the AMNPS from igniting pellets in other rows and billowing out smoke. I am 99% sure it is not jumping rows. I have 3 1/2" holes drilled in the bottom right of the unit and the same on the top left, both with adjustable vents that I run wide open. I have the AMNPS sitting on a brick that is placed where the chip tray usually is. Help me save my butts!
