@dwcraig1 - Ok your the second person with this issue using NiFe 52. Both you & Landman have had a similar issue with 2 different NiFe's yours with Ziv & Landman with Reactor Wire. Coincidentally your builds are almost identical& both on Sub Tank RBA's
@dwcraig1 - Since it's a Subtank RBA it would either be 7 or 8 wraps (legs go opposite directions means whole wraps) If you had 7 wraps then your build should be .24Ω & Landmans build below would have also been almost exactly .24Ω also albeit with 1 less wrap because the Reactor wire has more resistance.
The Common denominator here is the Sub-Tank RBA Platform
The DNA boards are extremely sensitive to connection issues so try unscrewing the RBA deck 1 turn & then use a punch or something to push the 510 pin up into the bottom of the ST base, then screw the RBA deck back down and give it a try.
I had the same strange issues with the Armomamizer and Crius too. I don't really know what I've done differently but I scrapped those first builds and now have an Armomamizer with Invar36(ie, NotFe52) and another Armomamizer with the Reactor wire and they're both running fine, both 26awg, on two different DNA200's - Hotcig/Opus. I have 24 awg Invar36 in one ST+, 26 awg on another, and 26awg Reactor wire in two ST+'s but they're all being used on SXMM's by my wife. Those first few builds that were unstable, I only pulsed them in power mode on a DNA40 in one large loop before coiling, and only as far as a dull orange, but they did turn dark.
On the current ones that are working, not only did I pulse the Reactor wire brighter before coiling, I used a torch on the Invar36 wire. Then I caught myself almost forgetting to re-pulse the first one after I made the coil and put it on the Armomamizer deck. I remembered right after I got the wick installed in the first coil and took it out and pulsed it to check for hot spots. Being so used to Ti and only pulsing it to the yellow/blue stage via the one large loop method, then installing, wicking, and vaping, I couldn't remember if I pulsed the Invar/Reactor wires after coiling/installing them on the first ones that were unstable. Oh, one other thing that's changed on all of these, instead of using the coil master to build them and then space the coils out manually, I made a little coiling rig using a 7/32 machine screw and a block of wood so the coils come out perfectly spaced - 2.84 ID each time. They're not coiled with as much tension as using a wire gizmo, but they've got 1-2 lbs on them when being coiled.
So, whether it was something with not pulsing them enough, not having the correct TCR (at least for the Invar36), not checking for hot spots, or some other random issue, they all seem to be working fine now for the time being... and it's been two weeks of use on all the coils except the Armomamizer with the Invar36 build and that one has been in use for about a week.
