Super quick update. Vaped on the Marquis for a bit. Vapes a lot better than my last nickel build did.

Then I checked the resistance to see what it was reading in at after getting hot. It dropped to .16. What the hell?

Edit: waited a bit, read it in at .138. Temp control is now working. I'll give it a rest and get another accurate reading in a bit.

Did you lock in the cold resistance using the up/dn buttons simultaneously?

Sitting down, facing forward.
Finally built my first Ti coil. Dual config 26g Unkamen in a Marquis... And I think I'm going to stop here until you guys weigh in.

My USA OhmMeter read in .335. My DIY Boxer SX350J read in .249. I set the temp to 400 to see if it heated evenly, and I'll be damned they both glowed as bright as the sun. I assume that isn't good.

Next, I wicked it, set the temp to 360F, and added some juice. Watching the screen while firing, it sets to 032F while firing and doesn't seem to have any temp control going on at all.

I've not had any issues with the board reading resistance on any other atomizer, so I don't think it's that. I also highly doubt the Marquis is interfering with the reading.

Edit: The ohm meter and the SX consistently agree with each other on all my nickel builds on other atomizers, and I've not had similar issues with the Marquis in the past.

Thoughts?

You assume correctly. The next step, after heating them that hot, is to pull them out and throw them away. Then start again and do not heat them like that, anything past a blue tint on the wire is just too hot. Not a good thing! Too much titanium dioxide will form at those temperatures, something you don't want at all.

Kinda what I figured. I was a little surprised TC didn't kick in and prevent that. Nooooooooow I know why, cuz the resistance was all effed up.

Parallel duals, 5 wraps of 26 gauge with 2.5mm ID should be a whole lot closer to 0.10 ohms than the 0.25-0.33 you got at first. My guess: Something wasn't making a good connection at first. I'd re-check all the capture screws first.

In fact, it's a good idea to re-check capture screws once or twice after putting any Ti coil(s) into service. Ti is a bit funny that way, what was a well torqued screw on a wire sometimes isn't after the coil has been fired some.

That's exactly what I thought. It seemed like it was initially reading one coil instead of two.

What's this about locking in the cold resistance? Haven't heard about that. Is this done in locked mode?

The guy that was having trouble was using a YiHi chip set and that is the way it is done for that chip. If you are using a DNA chip set and have the feature to lock the resistance you can it is your option. With the YiHi it is mandatory and not an option.

Don't think the DNA 40 has that feature. Thanks, Holman. BTW you are right about the yellow MXJO batteries --crap.

petemoss,

Actually the newer DNA40s have the resistance lock but if you are like me and bought in early we don't have the good fortune of being able to lock the resistance. I will say that when I get a good build and tight connections I find I don't need the lock feature.

If you are talking about where I said the MXJOs are Dog Poo-Poo I am glad to hear you agree except that probably means you were unlucky enough to buy a couple also. I have seen them advertising a version 2 of that battery but I would go near them ever again. :-x

I don't know if it's the new lock feature, or other changes, but the latest version of the DNA40 worked a lot better for me. As you know I got a replacement for my broken VF from Preston. I put the K4 with nickel build (that was previously on the old Flask) on the new one, and it worked miles better (it always worked so-so on the old one). Didn't even change the wick or coil, just "transplanted" the tank and locked it in, and was rather amazed. Like I said, it may be down to other factors - maybe my previous one was always a bit problematic. I did open the old one up and saw that the white 510 pos wire was a bit squeezed, maybe that played a role.

WideO,

I don't know what changed and I don't believe those Fanboys that were always claiming that Evolv never did any back room code changes but my replacement while it doesn't have the lock feature resistance wise was much better than the first one.
I do use Sterling silver crimp eyelets on the Ni200 builds so I am able to get extremely good connections and don't use the post holes on my Lemo2 or any other atty for that matter and I attribute a lot of my resistance stability to that.

Anyway it works and works well these days (knock on wood).

That's the key. When I started using my DNA40 with nickel wire ages ago I was mostly using Kayfuns. Then I switched to Genesis atties. All in all I think I've only ever built one atty with nickel that used post holes, and even then I didn't use it because the screws split the wire haha.

Post holes work better for cutting wire than my side-cutters. :-x

If the post holes are over-drilled they will act like wire cutters. Add the little cup effect that threading produces on the end of the screw and you have a perfect wire cutter. I stuff the post holes with nickel wire and grind the ends of the screws flat. Good, solid, connections and no cut wire.
