I’ve been trying with the glass turkey baster version of the machine. I’m using a torch lighter and not sure if I’m burning or if my dose is too small or low quality. I’m not getting horrible taste so I don’t think it’s burnt but all I’ve been able to achieve is a slight buzz. Any advice?

Yes, based on your info advice is: smoalk more!

But if you need more details on how to solve your problem, you need to provide more information first.
What dosage are you trying to consume?
I am not familiar with turkey baster version, but can imagine how it looks and works. How thick is your mesh? Do you preheat mesh before depositing spice on it?
How do you hold your lighter? What's direction of flame during toke? Do you hold it in? How many tokes?

I tried around 40mg first assuming I would burn some. After failing that I eyeballed adding more which was maybe 75mg. I figure I may have burned some of it but also noticed some crystallized inside the glass so I guess some is still in there. I tried 2-3 hits but not sure if I was too slow. Hits were held in at least 15 sec. The mesh is roughly a 1 inch ball. I did not preheat I just poured does in the lightly heated outside glass until it started to melt. I tried flame both passing across intake and pointed toward. Thanks for help.

First: I don't know whst's the potency of your spice but:

1) don't ever eyeball it
2) really, don't. Because for example with my spice good comfortable dose is 25-27mg. 75 vaped will most probably result in blackout if vaped properly.

Okay my general advice:

Your mesh seems to be unnecessarily thick. 1 inch is roughly 2.5cm which is too thick imo.
If you see some spice crystallizing on the glass it's normal. But at the same time you need to work at your technique.
Position your devolice vertically, so that mesh is facing upwards. Then blast mesh with torch for 5-10 seconds. If you see smoke and it smells like dmt it means you uad unburned spice left. After heating mesh carefully apply desired amount of spice (i recommend 15mg for beginners) to it. It should melt and be absorbed by mesh. If it doesn't completely, make a few passes with torch carefully over the pile of spice so it melts down into mesh.
Then position you device so that your lips are higher than the end with mesh, so that spice-loaded end is facing slightly downwards. This is to ensure that less of spice escapes flame into the pipe; gravity helping that.

Position your torch perpendicular to the mesh surface, but close enough that you are able to suck flame into the mesh.
You can preheat mesh by blasting at it fro the distance. So that it gets warm but no visible smoke appears.
After you are able to suck in torch flame into the mesh you will see white smoke in the pipe with the chrasteristic taste and smell. Inhale slowly but deeply. Hold for 10 seconds or more, then upon exhaling go directly for the second toke, here you should be able to point torch more into the mesh so that deep-embedded spice also vaporizes. This one should be finishin/clearing toke if you have mastered the technoque and dosage is reasonable. Third toke, unlike TMK suggest is not always required. But if you are a beginner similarly gold second toke for 10-15 seconds and go for the third.

But the most important: vaping spice can be hit and miss, it is just not as trivial as weed, especially for beginners so don't get frustrated, everybody goes through this stage.

I tried a few more. 20, 30 then 40mg. No luck. All I get is a bit of a buzz and slight pupil dilated. Maybe. Red more time between sessions. All were maybe 20 min apart. I’ll keep trying later.

I had problems using the machine, I would get sub breakthroughs 90% of the time. The machine is quite hard to use if not loaded properly, dmt would melt and flow away from heat source dribble down the glass so I was loosing a lot each time. Trying to get 3 tokes out of it was my problem, by 2nd I couldn’t really work out what it was in my hand let alone take the 3rd hit. I ended
Up getting the classic VG and can load up 25mg and get it all in 1 hit.

Not sure if this any help but me personally I found the machine a lot of hassle, get yourself a vapour genie or better the glass version.

I decided to take a bit of a break until I get another smoking device. I think maybe all the failed attempts were giving me just a low dose enough to feel the slight buzz and maybe I’ve affected some receptors from too many attempts too close together. I also wonder is it possible my hot water bath could have degraded my spice during extraction? I used a crock pot too keep jar warm. Not sure on temp or if it’s even a concern unless temp is really high?
