If you see the resistance change in EScribe and Replay is activated on the profile and theme if needed and Replay still doesn't work then with a cold atty measure the cold resistance and try again.

If your coil works in TC then it is most likely TC wire.
Use EScribe's Device Monitor to see if the resistance of the coil changes when heated. My example is using SS430 wire which has a greater change than SS316,
Replay must 1st be enabled in the profile in EScribe and use TC wire but depending on the theme it may need to be enabled their as well.

I then switched back to Viable Coils and Replay failed to activate so I switched it back to Dubious and it is now working again.
My opinion would be to use a material with a greater resistance change when building that low.
Here is a great place for wire and coils: https://www.zivipf.com/epages/63862298.sf/en_GB/?ViewObjectPath=%2FShops%2F63862298%2FCategories%2FAlle_Produkte

I had to change to Dubious Coils or Replay wouldn't work.
Be sure to upload settings after changing to Dubious Coils.
Just a small resistance change from cold to hot, from 0.196 ohms to 0.212 ohms.
I changed to a stock Evolv theme for this as well. I used this one:

First off Replay box on profile needs to be checked. Depending on the theme Replay needs to be activated from there as well, this situation had me going nuts for awhile.
Maybe save your theme and try another theme, coil wise I think it should be working fine.

Are you seeing this in EScribe or on the mods screen?

Hello! Thank you for yesterday!
Dry Fire is running properly. The other mods are stable, but only the billet box has a slight drop in resistance on the first firing.
Is this been with all coils that you have been using or is it just with this one?

A lot of good info here: https://www.e-cigarette-forum.com/threads/sxk-billet-box.898599/

Only when using TC capable wire. As it should. But with kanthal or nicrome the resistance should be stable.

Here are some situations that wreck havoc on getting TC to work properly especially when using wire that has little resistance change when heated. Things need to be pretty much perfect for these wires to be read properly by the board.
!st. is a coil with shorting wraps giving a false cold ohm reading, as the coil starts to heat the shorting may stop creating a jump in resistance.
2nd.A bad connection between the 510's, maybe atty's 510 is too short or has dirty threads on it's 510 threads or loose to wire post.
3rd. Wire not clamped under post screws tightly.
4th. Wrong TCR settings.
There has been some cases where LV put thread locker on the 510 threads where the ground wire connect internally on the 510 socket creating a problem with resistance readings. This was quite some time ago and I have not heard of it since.
Just to name a few, I'm sure there's more

Here is a snippet of my 2 cell DNA200 firing at 80 watts (set to 80). I was going to ask you to post the same of yours when I seen mine doing the same.
Here is why mine only reached 66 watts and not 80. All of the DNA boards that use cells in a series are buck only meaning that their output voltage will never be more than battery pack voltage. In this case the 200 board powered by 2 cells has a maximum output of 6 volts.
Note in my snippet that @ 66 watts the output voltage is maxed out at 5.96 volts (blue line), if I built a lower resistance coil it could hit 80 watts with the right resistance.
Could it be that you have the same thing going on?
The max voltage on a DNA250 board powered by two cells is 6.2 volts and the 250C is in that range also.
But looking at your build I doubt if that is your problem.
I would like to know what your pack/cell voltage drops to when firing. 6.88 v in my snip.

You said in your 1st post that the resistance was changing, what is the wire material?

Yes I have, as long as you don't have a nickel allergy you should be fine with it.

You might want give NiFe 48 or 52 a try, is lies about in the middle as far as resistance change.

Wire that changes the most resistance when heated work best.
Go here to see TCR values: https://www.steam-engine.org/wirewiz
Use the drop down menu to change wire type.
Read the value in "TCR in Vaping Range"
Note Ni200 is 6000, that would be 0.006 for the DNA TCR setting.
Personally my wire of choice is SS430 which has a much greater resistance change than SS316.

Does the battery cap screw in? If so try cleaning it's threads and the corresponding threads on the mod with a q-tip and alcohol.
Look down inside using a light and see if the positive battery contact looks clean.

My guess is there is a problem with the wiring between the battery and board. Look first at the battery contacts. Does the battery fit snug? There may be a cold solder joint where the wires solder to the board. Does the mod use a ground wire from the negative side of the battery to the board or does is use a chassis ground?
Is is not because it's a 21700.

When using Replay profile "Watts" is the material to select but you must use TC capable wire for the coil.
In the TC profiles Replay can also be selected, in those profiles you select the material that you are actually using.
