Excellent point and I did not mention I only stem pack the MI3.It's my experience that it mostly comes down to technique. A combination of button presses and draw speed. The issue is everyone has different lung capacities and like with wind instruments, everyone has different embouchure muscles so technique will often be unique to each specific person. There are baseline similarities for sure, but you will need to adjust according to your own physiology.
Having said that, I've found that a stem pack is much more forgiving than using a basket screen when trying to figure out the device for the first time. Moving the load even a couple of millimetres away from the heat source makes an enormous difference. It's much more forgiving and will allow you to hold the button down for longer periods without scorching. You still can scorch and even combust packing this way, but it's a little more difficult to do than with the basket screens.
The flat screens I use are 14.8mm and can be found domestically (if you're in NA) at VGoodiez and a few other places. You can also order them from overseas for much cheaper, but it will take a bit longer as with most things.
I'd also recommend trying to vary your grind. I find too fine a grind tends to hotspot for me with a lot of my convection devices.
The MI2 I have won't produce vapor in a stem pack and has to have a basket screen type setup to work at all.
No modulation on it a five second warmup and slow draw does make nice vapor in those wood stems,really nice vapor.
