I got my MES 30 a few months ago and have been smoking using the chip tray. Decided to get an AMNPS, and read the thread about reversing the screw direction on the chip tray holder to get the AMNPS to fit properly. I've done that, but now the screw sticks out so far on the other side I can't get the chip tray back in (which from my reading I do need to stick it back in, just not all the way to allow proper airflow to the AMNPS).
See pictures below. Anybody have this issue? This MES 30 is fairly new (Christmas 2013), wonder if the chip tray design changed?
