First time with temperature control and my head is dizzy!

[dangkhoa02106]

My coil is SS316L (24awg) and the atomizers that I use are Serpent Mini and Serpent RDTA.
I built almost the same coil for both atomizers. (The resistance did not jump around and I did not lock it.)
I used the default profile for SS316 (set the power to 40W, the temp to 420F), with the Serpent Mini the vapor is very very hot but there is almost no vapor with the Serpent RDTA. When I press fire button, the power pump to 40W and just after about 2s, it drop to only 7W to 10W because the temp is protected.
I tried to edit the preheat, the TCR in Escribe but nothing are improved.
I also tried to define the new material with .csv file from Steam Engine, too.
Help me
By the way, is there any premade profile available? I will try to build the same coil with this profile.
Nearly forgot, the resistance is 0.35.

I assume this is on a dna mod. Is the mod new? Which board, dna 75 or 200/250? Finally what does it look like when you try to use it while hooked up to device Monitor. Device monitor is a powerful way of troubleshooting your issues.

IDK about DNA mods but if it's NOT you need to lock the resistance when cold... in order for the mod to regulate temperature. . The locked value it the mathematical constant factor.

Yup, my mod is new, Vt75 nano.
I already fix all the problems. Just because I was wrong with the define process.
There is a lot of fun in Escribe, this is really an interesting and useful software.

DNA mods should not have the resistance locked as it continually refines the resistance measured. If you must lock the resistance something is wrong.

Play around with wattage. I have had lots of problems with TC if the wattage is set too high, throttling to the point of no vapor. Also the same with temp set too low. I use the built in 316L TCR and get good flavorful vape.

Is the coil a spaced or micro coil? I have found that TC doesn't like Micro coils....

Also you can get a custom profile to download and upload to the DNA device on steam engine's wire wizard.

A comment on your setting 40W. I know people will modify TC wattage, but with DNAs, this would generally only be to combat the resistance change not being consistent in a build. Where I have had this resistance issue is with contact coils and dual coils. You can get these working, but it takes more work. There might be other conditions resistance change is not consistent, but I haven't run into them.

I like it simple and just stick to spaced single coils for TC; My gotos are spaced fused claptons, and they work just fine in TC even though they are dual and contact technically. My triple 18650 dna250s set to max 180W(because of the batteries) for preheat punch and tc; and my dual 18650 dna75s set to max 75W. Only thing I ever do is temp up or down. As simple as wattage mode.

I already made a single space coil. I just use "Analyse atomizer" function in Escribe to read the resistance and choose an acceptable value for my coil. SS316L is an alloy and there is so many manufacturer out there so the resistance will not exactly the same with the value given by Steam Engine. It is really annoying.
By the way, as I search, I choose Preheat at 1W, Punch at 1 and the time is 0s. That values make everything "seem" right.
I really do not know the difference between "Ohm lock" and "Ohm unlock". As I know the real resistance value and the resistance value given by Steam Engine are not the same so the CSV file could be wrong. Should I redefine the resistance and lock it (to match the resistance value in CSV file)?.
One more silly question, TFR table on Steam Engine is for DNA200. Will it all right if I use it for my DNA75?

The DNA table is the same. I don't think you need to lock the resistance for the DNA device, I never do. But for Pico I have to lock it.

Don't lock resistance either in the analyzer or the mod.
Don't change the read resistance to match what Steam Engine says. I use S-E as a guide, see if my build/install is ok, not as the actual value. I do the building after all and there are variations in wire and build.
The CSV is fine for any DNA (and even for Arctic Fox)

I have a 26g/36g ss316l fused core Clapton 3mm 7 wrap I believe at .27ohms on a Entheon atty on my Therion 75c be mod in tc.

My settings are 485f and 28watts. Lower your watts as its hitting temp too quick and throttling to keep the temp at 420f.
