jaysocal is the first person to understand my question. if i lock in a .3 ohm stainless steel coil at .300 shouldnt it stay locked and show that resistance the whole time? and fire under those parameters according to that particular locked in resistance? can i not lock it in to fire under the same settings regardless of the live ohms changing as the stainless steel heats up?
The "ohms lock" only locks the so-called "cold" resistance of the coil which is used as the baseline for temperature control. It does not lock the "live" real-time coil resistance.
You cannot make a DNA 200 act like a mechanical mod (without jiggery-pockery!). If the resistance of the coil is changing the voltage will be modulated to provide the wattage you have set (this is a power control device).
Evolv would need to implement a ''mech'' mode or someone come up with some method to trick the DNA into behaving like a mech like creating a custom TCR curve and running it in TC mode with a high temp but the power setting to give you the voltage you want - if there isn't enough power to heat the coil to the set temp the board will output that voltage without modulation.

definitely a bug.
I'm sure the evolve guys will need to know the revision of Escribe and firmware you are running so maybe helpful if you also post that information. -

No 9-30 was the one pBusardo was using
I think lewiss means that many of the revisions in this latest firmware release where improvements suggested by Phil during his DNA 200 review.
I still think the most important one is missing... being able to directly adjust the temperature when in TC mode (without having to do the ''lock/hold/unlock shuffle'' each time). Phil was screaming it at the end of his 'thumbs down'' section of the review which was quite funny.
EDIT: Droopydroors got there before me

does the profile you're using for ss wire have the ohms lock activated?
sounds like the cold resistance of your atty and the baseline the board is using don't match. make sure the lock is off on the mod so it can do it's refinement and find the true cold resistance. -
Nice mod, liking your work
Is that a wet paint or powder coat finish? -
Nice post and thanks again for sharing.
Can I ask what 3D printer you are using? I'm looking into buying one so interested to know what you use and the price point.
Thanks again. -

You want to try living in the uk! We use Fahrenheit in the summer! " ooh what a scorcher heatwave hits 105 degrees" And Celsius in the winter "Black ice warning for motorists as temperatures expected to be -6 degrees"
I'm from London, now living in Buckinghamshire lol.

May I ask why you are using a mosfet for such a small current circuit?
Seems all you need is a standard transistor circuit with a pull-down resistor? You're trying to replicate a single pole N/O switch, right? -
Agree with OP.
In TC mode 99% of adjustments I make are to the temperature. The wattage is only going to affect the ramp up time of the coil to get to the preset temp (assuming there is sufficient power to get the coil to that temp) and the proportional component of the PID used to regulate the temperature.
It's actually pointless setting excessive power because the device throttles back the power once the set temperature is reached. -
Hi Guys,
Any chance of providing a setting in eScribe for overall display of units in Celcius or Fahrenheit?
It's especially annoying for people like me who live outside the US when temperature displays in Device monitor for example default to °F when we are used to working in °C. I know the traces are displayed in the units selected on the device but in the left-hand panel the temperatures are still displayed in °F. It would also solve the annoying issue of having to select °C from the drop down list in Profiles whenever you want to manually input a new temperature setting.
Thoughts?
Many thanks for all your great work so far, really enjoying the board, features and companion software.

Thanks Bap & Nick... good information to know.
I didn't see any 3D Models specific to the 510 or are they in the model for the reference case? (Only have Solid Works at work so can't open it at the moment since I'm at home). -
For those of us outside the USA it's far easier to get Metric equivalents M1.4 /M1.6 You'll find them online very easily.

Does anyone know how to set up the csv file on steam engine for the SMOK TFV4 Titanium coils? They are a dual coil atomizer with a resistance of .33 ohms. I tried setting up a csv file as a parallel build because that was the only way that I could get a 2 coils build to register with the file, but the tank gets way too hot and the flavor is off, not burnt though.
Also, would I use the default NI-200 settings on the DNA200 (Hcigar VT200 mod) for the TFV4 Nickel Air atomizers or do I need to male a csv file for these coils as well? They are dual coil and have a resistance .12 ohms
I think I can figure it out if I know the proper way to pull up a dual coil setup. Any help would be greatly appreciated.
Ni200 coils shouldn't be a problem. Irrespective if they are connected in serial or parallel the DNA200 will see all the coils as one coil and the inbuilt TCR should work (assuming all the coils are the same resistance of course).
The Ti is a little bit different and I've had similar problems to you when downloading the CSV from steam-engine for dual coil and clapton setups. The TCR seems to be a little 'off'. I think the problem is that there are different variants of Ti in the market and unless you know the exact grade and makeup of the Ti you have it's a lottery if the TCR will be 100% right or not.

Ya know is it just me or doesn't it seem as if even with everything setup/wired properly that the DNA 200 when in 2cell / dual 18650 has stability issues? It seems the chip looses its reverse battery protection, also it seems to also loose it's cell monitoring feature aswell & quite possibly it's low cell cutoff point. Is there any reason Evolve doesn't have a public 'schematic' for dual 18650, yet there have been firmware updates to support the feature, but no schematic. I love evole's products, but with this chip I don't understand the lack of information , even with it being a newish board. Have I missed something that EVOLVE has made public of the dual 18650 setup & acknowledging the feature losses / instability? Any information would be appreciated.
I think I'm correct in saying that the board was originally designed to be used ONLY with 3s Lipo's. The 2s scheme was done in response to customer requests and that's why there is no reverse battery protection in that configuration. I think I've seen somewhere that Evolv are developing an add-on board to provide reverse battery protection when using the 2s scheme.
Regarding cut-off etc. all work with 2 cells - all the mods I make are 2s 18650 and on board charging, cell cut-off and monitoring all work fine. I think there's more than enough information on this forum if you search to be able to put together a 2s mod.
I'm not sure what you mean regarding "instability?" -
I've never seen or owned one of the original reference mods so can someone explain to me what's the deal with the 510 connectors on these mods? What is it about the design that makes it so much better, than say a FDV item, which is what I use on all the mods I sell including the 3D printed reference mod I've built?
Then the next question, of course, assuming they are as superior as people are saying will they be made available to us mere mortals?

It's not the 'Final' design, it has some rough edges but as a beta I don't think it come out too bad. -

[QUOTE=lexalove]So you admit there is no scientific proof either way. Therefore me, you, nobody knows for a fact if it's harmful or not. So regarding vaping on a Ti coil that may have oxidisation on it, why take the risk when there is no need to?
I advised the poster to bin his coil after he had an obvious hot spot, wire is relatively cheap, there is no need to take the risk no matter how small any perceived risk may be. Just wrap another coil, vape and be happy.
Don't perpetuate one myth by denouncing another perceived myth when NOBODY really knows the facts either way.
Look, you said TiO2 is a "carcinogen and causes lung damage." That's all I disagree with. I think I've been crystal clear.
I never said I use Ti or don't. I never said it was safe or not safe. All I said is that the statement you made is not backed by the science, is nothing more than folklore, and it is a bad idea to continue to repeat it.
Your aim is, I believe, to warn folks that vaping TiO2 might not be a good idea. Why don't you just say that?[/QUOTE]
OK Mr Pedantic lol, vaping TiO2 is not a good idea it may be carcinogenic.
So instead of all the diatribe why not just say it may not be carcinogenic, nothing is proven one way or the other, but it would be a good idea to bin the coil?

Mad Scientist said:
Typical actual study rather than "prevention principle":
http://annhyg.oxfordjournals.org/content/49/6/461.full
"The epidemiological investigations evaluated the mortality statistics at 11 European and 4 US TiO2 manufacturing plants. They concluded that there was no suggestion of any carcinogenic effect associated with workplace exposure to TiO2."
"The epidemiology studies investigated whether there was a link between increased incidence of lung cancer and exposure to TiO2 dust. In all the studies the overall conclusion was the same: âThe results of the studies do not suggest a carcinogenic effect of TiO2 dust on the human lung'".
There are many more studies like this.
The thing of it is, we know that TiO2 is bad for rats but not mice or hamsters. We can't do a controlled study on humans because that is obviously unethical. European and US Health studies of TiO2 factory workers have not revealed an increase in cancer rates. From this it cannot be reasonably concluded that TiO2 is a hazard, yet that is exactly what was concluded by some international health organizations and then spread and repeated far and wide.
The bottom line is no scientific proof. Yes, it might be dangerous or it might not be. I'm not trying to be a jerk or anything but I bristle when the same junk science gets repeated over and over long enough that the general public picks it up and repeats it over and over and low and behold, something with no legitimate scientific proof becomes fact.
So you admit there is no scientific proof either way. Therefore me, you, nobody knows for a fact if it's harmful or not. So regarding vaping on a Ti coil that may have oxidisation on it, why take the risk when there is no need to?

+1 For me also. would love to see an escribe setting for adjustable scroll speed.
+1 from forum member windxrunner...windxrunner said:Is there a way to change how fast the wattage scrolls when holding down the up/down buttons? I found it pretty annoying that it will go at a "normal" speed for a second or two, then the accelerator kicks in and it goes like 50w per second. I end up holding the button for a second, letting go, holding down the button for a second, letting go, then holding down the button for just slightly too long and I'm like 40 watts past where I wanted to be. It's driving me crazy.

I agree with you windxrunner. I'll post it in the 'Feature Request' section.

You are spreading folklore, not science. The way the studies were conducted, everything is a carcinogen. I can design a study that will kill lab rats with oxygen. Should we say all over the internet that oxygen is a poison?[/QUOTE]Mad Scientist said:[QUOTE=lexalove][QUOTE=Mad Scientist][QUOTE=lexalove][. . . Titanium dioxide is a known carcinogen which can cause lung damage . . .
I think it's well accepted that Titanium Dioxide is a bad thing to inhale on a regular basis. Years ago people used to say cigarettes were harmless, but we know better now don't we. If you wish to take the risk that's fine, it's personal choice at the end of the day and who am I to tell you what risks to take with your own body.
I was giving advice to a fellow vaper. It is his choice if he heeds that advice or not.
[/QUOTE] I'm not trying to start an argument but it's not "well accepted" and in terms of the existing panic based on conjecture rather than facts among the general public against vaping, it doesn't help us if we ourselves add to it. This is another case of repeating something often enough makes it true. If you want to caution someone that the effects of inhaling TiO2 are not fully known and remain controversial, that's great. If you want to say some very poorly designed studies indicate inhaling ridiculously high concentrations of very fine TiO2 dust may be harmful, that's great. When you republish the garbage that it's a known carcinogen and causes lung damage, that's folklore not advice. As far as who takes what risks, you are reading something into this conversation that's not there.[/QUOTE]
No idea what that last part of hyperbole meant but you do what you feel is best. Inhale as much TiO2 as you want and be happy. -

So on the new setting I got longer time before temp protected but any long pulse and it's burnt and fires up??
You need to throw that coil away!
Anyone using Ti wire... do not under any circumstances allow the coil to glow orange/red and if for any reason it does throw it away immediately.
When Ti glows it oxidises and Titanium dioxide is a known carcinogen which can cause lung damage.
Looking at your picture I would guess your last coil is a slightly bigger diameter than the rest of the coil and not coming into full contact with your wicking material that's why it's getting hot. I've done the same thing on numerous occasions with Ti coils. I always put a 90 degree kink in the leg on one side of the coil so both coil legs come out on the same plane, I've had no issues since I've started doing that.
