Hey, I'm an exclusive machine user for about 10 years (minus a month or two of lightbulb-pipe failures

)
Some of the things I say may be debatable, but I'll just give my experience/opinions.
What I can tease you with is to note that I have no problem smoking 30mg smoothly off a machine-bong in 1 toke, promise!
The simple one-hitter with machine is alright, but 95% of my experience is with a machine in a bong. Honestly any bong that smokes weed smoothly will do DMT off a machine no problem. If you don't have one, they are fun and easy to make (Google DIY bong).
I don't recommend doing weed and DMT at the same time, but I don't smoke weed at all so I may be biased.
In my experience, you CAN'T burn DMT on a machine to the point that it doesn't work. You CAN make it so hot the smoke hurts your lungs, but you have to really torch that little ball to make it happen.
How I smoke it is:
I use a torch lighter and place it directly on the machine ball while toking for about 1 second, then take it off for about 2 seconds, then back on for 1-2 seconds. A lot of people prefer "feathering" the flame on it, but for me that's just a little too complicated.
I just continue the on-off with the jet lighter toking smoothly, adjusting how long I place the flame based on any urges to cough (flame on the ball longer if no urge, longer off the ball if a large urge)
When there seems to be less some coming off of the machine, I torch the shit out the ball until it's red to make sure I got everything off of it. Then just clear the bong and hold it until I'm in hyperspace (or sub-hyperspace depending on dose)
Edit: quickly reading over my post, this torching-til-red might be a part people would chime in on not to do for safety/health reasons. Happy to hear from those about whether this is safe or not.
Anyway, this is just a ramble from a machine fan-boy, hope it helps.
