Hi, thanks for trying to help me.Howdy, welcome to the Forum, sorry you're having troubles.
This happens to new guys. You have other options, I suggest you try them. Stop doing what's not working (change something), if you don't the results aren't likely to change.
You know vaping works great if you can control the heat properly, right? Therefore, that (heat control) must be the problem. Specifically, you're putting in too much heat......more heat than you can use to make vapor.
Forget the instructions for a bit, experiment. Sneak up on the temperature. Heat for say 3 seconds (not enough), let it coast as you hit on it (fairly gently, you'll looking or vapor) for a few seconds and give it another 3 or so seconds. Gradually increase the ratio of on to off times to bring the temperature up.
As the battery discharges, and as it ages, along with the surface of the mesh 'breaking in' this action (rapid heat transfer) will slow some. Soon they will combine so that it'll be harder and harder to combust on purpose, eventually becoming all but impossible.
For now, stop feeding it too much power, it's making it too hot........
Stick with it, you'll sort it out.
Good luck.

The problem continues, I have now "wasted" about a gram of good medicine in the mflb. Probably tried it 10-15 times with the same result, combustion. I have how ever noticed that the burning occurs in the same spot in the trench every time, the bottom middle and slightly to off to one side. I am thinking it must heat the screen uneven, is this possible? The herb in contact with the sides or walls of the trench does not burn, only part of the herb in contact with a small area of the "floor".
I´m pretty sure its not my technique, as i own several other (desktop) vaporizers where draw speed is a factor. Bought the mflb mostly for fun as i already own other portables such as the solo and O phos.
I just wanted something smaller then the solo for dry herb, so i bought the mflb after hearing and seeing much good. Is uneven heating common with the mflb? Has nobody heard of this before? The problem seems to bee a very small area in the bottom of the trench.
Thanks
