Can I use SS 316L for coils in a temp control mod and what do I set the mod on " Ni200 or Ti " ?
Thank You
Thank You
Ive tried contact coils with minimal luck but that was on 1 build.
Then i tried spaced and its working as designed.
Any thoughts on spaced or contact
Really? I have contact coils in my Velocity mini on the SX M class that seem to work fine in manual TCR.I haven't had success using contact coils with SS in temp control. I always use spaced SS coils.
Really. Although I've only used stainless steel in temp mode on tanks using VTC Minis. I run kanthal Clapton coils on RDAs.Really? I have contact coils in my Velocity mini on the SX M class that seem to work fine in manual TCR.
Seems to work very well on the SX!Really. Although I've only used stainless steel in temp mode on tanks using VTC Minis. I run kanthal Clapton coils on RDAs.
The SX is definitely awesome.Seems to work very well on the SX!
With mine I had to use spaced wire or it was very erratic.Ive tried contact coils with minimal luck but that was on 1 build.

So one thing nice for sure .... I'm going to have to start spacing. My build now isn't really acting right... switch to power... 60w no sweat. Doing great. SS definitely has a lot of advantages for TC.... and if you want to turn it off... you can.
I talked about it a couple posts up... But basically, I think resistance is even across the whole coil. I think current, and therefore heat/resistance jumps across wraps. All the board looks at is total resistance rise. So it sees a rise, and cuts power accordingly. But that rise is only in a small part of the coil and not all of it. So you get power in a small part and not the whole coil. That is not utilizing the whole coil and producing vapor.What is it doing? And why do you think spaced coils would fix the problem?
In temp control I tried closed position and it was erratic until I started spacing them. I was also told to space it in temp control.I'm curious whether most builders do this with SS.
Is the majority spacing SS coils?

Just curious are you making your ajustments when the coil is at room tempature. And while at room temp are you locking your ohms. And when you do lock your ohms at room temp is it the correct ohm.I'm at a bit of a loss.... I'm using 430 that has a TCR of .00138. I went to juke it because my vape is hardly there. I had to go all the way to .00170 to get something I'm used to with other coils. This is on a spaced coil too. .00180 probably would not be too bad either. I don't exactly know what to think. That is a big change for a SS wire.
Dude, so I have a weird idea on what's happening....I talked about it a couple posts up... But basically, I think resistance is even across the whole coil.

Most tend to complain about a cooler vape than should be, or burnt hit and not wicking right. I'm thinking it's not the whole coil and localized hot spots. In power mode it wouldn't be noticed. Power is delivered and eventually with contact coils it would heat even regardless.
I opened up a new spool 2 nights ago and now im on my third build with third different atty and its acting hinky.
Can't help but wonder if UD didn't throw out a bad batch or if the did a coca cola move and changed the recipe-bastards.
I run both spaced and microcoils on SS. Makes no difference at all with the 2 devices I use that support TC on SS.
I have had this same issue with UD wire... its not like UD is making wire man they are just sourcing it.. I am betting that some of the so called 304 wire is probably 316 and vice versa... I have seen bizarre problems with different grade stainless and the same grade by different vendors I have a hypothesis but you may not want to hear it there @f1r3b1rdDude, so I have a weird idea on what's happening....
Been using SS for tc since I got the dna200 and have been using nothing but the UD 316L, with zero issues at all.
all my coils have been built just like my kanthal. Went through 2 rolls of 24g and a roll of 26g. I opened up a new spool 2 nights ago and now im on my third build with third different atty and its acting hinky.

There be minor variances from one 316 to another, but very minor. I can't see a big impact on TCR. There is no company making their own wire. Everyone sources commonly available wire. And suppliers source commonly produced grades of SS. This isn't rocket science. Batches by the 1000s of pounds. And they have to be QC'd. For us it's no big deal... But there are many applications that blend does matter. And all you have to do to get the blend you need is to spec the grade/alloy of SS you need.Dude, so I have a weird idea on what's happening....

Roger.... Im not a metallurgy expert, but I have a reasonable grasp of electronics and the process used. I've also had a dna40 since the first beta mod that vaporshark put out.If you're not a metallurgist or chemist how can you know the purity of a grade you buy. Ok, here's my thoughts on TC and wire. You were just about to ask, right?
TC functions by reading resistance change from room temperature. There is a scale, or band, which goes from room temperature (I think they refer to it as 58F) up to, whatever. Across this band are known resistance increases that correlate to specific temperatures. sidebar - that's what makes the dna200 superior is the ability to customize how your mod treats a wire. If you go to www.steam-engine.org/wirewiz and click Graph in the TC Results pane, then below in the drop-down menu select Ni200, then SS and then Ti, you will see a graph of this band. Notice how with Nickel and Titanium the graph has a far more dramatic slope than stainless. SS is nearly flat. This means that there is far less room for error with SS (all grades) than with the other two commonly used non-resistance wires. And as we all know, resistance fluctuations can occur rather dramatically with even the slightest bit of a bad or loose connection. So if your atty isn't 100% solid, there is any iffy solder joint or coil screw not 100% seated, those things will cause sudden resistance changes that the TC mod will pick up on and adjust to accordingly. I also suspect with heating/cooling the expansion and contraction of the coil wire can have an effect - at minimum by loosening the deck screws some. So when you're using SS and there is already very little room for error, well I think you see where this is headed. It's not to say that I think SS is not a good wire for TC, rather it's far more prone to error than the other two mentioned and therefor inferior for TC. It rocks in wattage mode though!
I do not use Nickel for a variety of reasons. Stainless - I have it but don't use it much. Titanium is my wire of preference and I get very solid, stable and consistent TC performance from it.
Hmmm, you're right... It just baffels me, how all of a sudden, the change. Unless its just kind of a rutt. HahahaThere be minor variances from one 316 to another, but very minor.

So sure there is some unknowns, but I can't imagine huge differences 8n material.
The company I got the wire from, your wire, sells SS in many different forms, in many different alloys for many different applications. I'm sure our 430 comes off a 1000 meter spool of welding wire. If they say it's 430, I obliged to agree. Because they sell several different grades for vaping. Doesn't make a difference to them what spool you want it off of.
If it was wrong on the other end of common, 316, 317, 304, those are all much smaller TCR... My vape would be too hot using 138.
All that is true. However, I have had unstable ohm problems. It usually makes a burnt hit. It never reaches temp control. I check all my re coils on escribe to make sure they are stable. Crowns will become unstable and I'm betting it's the nickle leg connections. But again, I have experience with that problem.

C'mon man, when I have I not wanted to hear your thoughts? LolI have had this same issue with UD wire... its not like UD is making wire man they are just sourcing it..

YOu answered it with your quote "its always the Aliens" I do think I will have to get off my lazy ass and do some kind of experiment. I am betting that it has to do with the leg length of the coil and how long it takes for the chip to identify resistance because if the idea to space coils is sound then that indicates it takes a longer strand that has the same characteristic to be detected.. Now again its probably just AliensC'mon man, when I have I not wanted to hear your thoughts? Lol
They should go surfing. -hahahaYOu answered it with your quote "its always the Aliens" I do think I will have to get off my lazy ass and do some kind of experiment.

If I take Crown at their word, the wire is 316
No, you don't lock ohms just for TC. TC is less accurate when you do and Evolve warns you about locking ohms. Also, if you lock ohms and coil looses contact or shorts, there can be bad consequences. You only lock ohms if your ohms are unstable when sitting on the desk not doing anything. The fix for that is to check connections and get them stable. But you can lock or override ohms if you want.Using tc mode you always lock your ohms or you get erratic OPPERATIONS. It is not like power mode.
I am building mine on the Crius, but I use crown stock too in TC. Just offering an example of various coils.I was really referring to making your own coils. I sometimes forget a lot of people buy stock ones. I need to stop doing that !

Irratic ohm readings during a pull do not matter. They should be steady, and people can get them steady, but even if my graph is moving around with temp/ohm/power... I can't actually tell from the vape.
Now if you look at all the vids and including Phils they tell you to besure to lock ohms. You must be talking about an old artical. I have two and if you don't lock ohms you get an erratic operation.No, you don't lock ohms just for TC. TC is less accurate when you do and Evolve warns you about locking ohms.

You might want to take that up with Phil then because that isn't true according to the people that made the board. That isn't how you are supposed to run TC.Now if you look at all the vids and including Phils they tell you to besure to lock ohms. You must be talking about an old artical.

Na dude, he's right for the DNA. There's a thread about it in the early adopters forum at evolv. That's why the first few versions (lol) of the dna40 didn't have atty lock. Evolv prides itself on accuracy, and the board is designed to run at its most accurate without it. They put in atty lock because it is more forgiving with builds that can have some less than perfect connections or modders that have some less than perfect solder points.Now if you look at all the vids and including Phils they tell you to besure to lock ohms. You must be talking about an old artical. I have two and if you don't lock ohms you get an erratic operation.
Great reason I no longer view his videos you get X so called community expert spewing crap and the misinformation spreads like gangbustersYou might want to take that up with Phil then because that isn't true according to the people that made the board. That isn't how you are supposed to run TC.
