Hcigar VT75 Nano Temp Protection warning

[MidwestExpress]

Hey everyone,

I got my VT75 nano today. I loaded my custom curve for my 430ss fc's I use and setup a profile for it. I put my tank (wotofo conqueror) and when I took a hit, I got the temp warning. If I unscrew the tank and fire and then screw the tank back on, it fires just fine with no warnings. Vapes great too! If I let it sit for a bit and it goes to "sleep" it will start throwing temp warnings again. I have to keep loosening the tank and putting it back in to get it to fire correctly.

I am running a Sammy 25r in it. I have never had this issue with my dna200 mod but I know this a whole new chipset and it is different.

Are there any settings I'm missing with the dna75? Something I need to tweak?

Thanks in advance for help!

I was getting that issue with the smy75, I went ahead and set the mod resistance in escribe and the problem went away.
wingsfan, "The DNA Whisperer," may have some other ideas. he uses ss430

So you locked the resistance in escribe?

its a copper threaded plug/screw that you screw in and run the analyzer to get the mod reisistance - as in the internal resistance of the mod.
it helps the board with accuracy and its calculations

this is the screw thing

I don't have the copper analyzer adapter. I take it that is something extra to buy. Never used one on my Lavabox.

The only 3 things I can think of are:
1. The mod's internal resistance is set to high, making it think the tanks resistance is lower than it is, causing it to limit out too quick
2. The SS430 wire might be off. Is it from Unkeman Supplies? There's has always been spot on. I recently got some from CW that I had to raise the TCR considerably to work right. The formula has to be off!
3. The TCR/curve you set is off. I use the SS430 curve from Steam Engine.

Hope one of those helps. You are having to trick the mod into locking a higher resistance now to get it too work correctly.

Cheers,
Steve

some come done... some don't...
its 11 bucks- go chek my previous post, I added the info to it.

its well worth the investment.... OR ..... you can try fiddeling with it, but all mods will be different,
I have mince set to 0.003

430 is from Unkeman. Only place I buy it from.

Tc curve is the same I use on my Lavabox. I just loaded it into the VT75 when I unboxed it. I have a feeling that it is internal resistance being the issue.

I will have to mess with it tomorrow when I get to work. My only laptop at home is Linux and even with wine I can't get escribe working reliably.

Sounds good. I would probably try .003 as the mods resistance to start. I've never went over .007. If nothing works you can try loading my ecig file from my Blood Red Lavabox DNA75. The link to it is my signature. It has custom screens, custom theme, 7 TC profiles, 1 for power. It's loaded. I'm using SS430 on it right now with a Supreme and it's working great.

One other question; Have you Downloaded the new Escribe version and updated your mod yet? The link to that is also in my signature. Good Luck!

Steve

I did snag the new software when I started messing with it. I knew I would need it since my software was dna200 only.

I will set the resistance to .003 and see what happens. I will buy one of those copper adapters and see what I get.

Thanks for for the help everyone!

I thought of one other thing. I don't have the Nano but I know the VT75 has a screw by the battery cap that is a ground screw. Some were having problems because it wasn't tightened down enough.

The latest version of Ecribe (8-8-2016 - V1.2 SP3) works on all DNA mods - 250, 200, 75, and 60. It also comes with a service pack to update the firmware. More of an informational post. I'm using it and so is Firebird. It smoothed out TC with SS316 tremendously.

 

[MidwestExpress]

So I did some testing with my Lavabox and the Nano since I don't have the DNA calibration copper on hand...

Readings from Atomizer Testing
LB = .178 ohm cold
LB = .178-.179 raw

Nano = .178 ohm cold
Nano = .180-.182 raw

That is quite a bit of difference between the two mods. I went back and forth with the same tank between both mods and would loosen the tank and tighten it back down a few times before taking a reading. The readings were constant thankfully.

I checked the mod resistance on the LB and it is 0.

Any thoughts as to how I should adjust the Nano to get it happy?

 

[Wingsfan0310]

Hook the mod up to Escribe and click on the mod tab to check what the resistance is set at. If it's 0, try inputting .003 -.004 and see if that helps. That's all I can think of atm.

I did that this morning. I did .003, .0035, .004, .0045, .0048

Everything I set it to... Same results.

Hmmm. I would try cleaning the 510 connector with a q-tip dipped in rubbing alcohol (not dripping wet) then. When in doubt, I always try cleaning the connectors (mod and atty). I'll think about it some more and post if/when something else comes to me.

Are you using the same firmware on both mods? It's listed in the bottom right corner in the Device Monitor when the mod is hooked up to Escribe.

Steve

 

[f1r3b1rd]

I've never heard of it being so high.... but I'm inclined to think try it at 0.012 and see what happens

also: have you tried using a different metal for tc with it to see if the problem isn't the metal or the way tc is set up in that profile?

Right now I only have 430ss on hand. That is what I have been using for a while now on my Lavabox. It has always worked great on there. I transferred the TC profile from my Lavabox to the Nano so that I would have the same curve and temp values. I figured that it would just work... I have found myself to be sadly mistaken there! HAH

Do you mean .0012 and not .012?

You could always download my Lavabox DNA75 ecig file and try it on your Nano. Save your ecig file first so if you don't like mine you can easily reload yours. Mine is working great on SS316L. The link is in my signature. I emptied the material tab and loaded the same profiles I use on all my mods (from steam engine). Added custom screens, theme, 7 TC profiles, 1 for power, 25R battery discharge curve, etc. The case thermals would be different but Hcigar never fills those in, they are just the default settings (at least not in my mods). Nothing to lose by trying that imo.

I will try that too then. Like you said, not going to hurt to try!

I wanted to the Lavabox M, but when I got the Nano for $62 shipped, I couldn't pass on that. I will still pickup a Lavabox M around Christmas though. My Lavabox has been my favorite mod out of all that I have had. I want a second one that doesn't have the 1300mah upgrade too for a backup.

 

[MidwestExpress]

OK, I have the lavabox m profile loaded and will test on the way home. Update to come later tonight. I also got an alcohol swab and cleaned everything out. It seems to have some grease down in there. I couldn't see it but after I wiped it out, the alcohol swab had a gray almost black smudge on it. Pretty funky. Now everything is shiny and the tank threads a bit easier too. Also, the tank is clocking in on the screen at .17ohm now and not .18 or .19. I am guessing this whole time it was that greasy film all over the 510... So we shall see!

 

[MidwestExpress]

Even after uploading the new profile, the coil will still not fire correctly until it has reached .19 ohm. It starts at .17 but then throws the temp protection alert and then I have to take the Adam miser off of the mod and then screw it back on and hit the fire button. Then it asked me if it is a new coil at .19. After I click yes to that then it will fire just fine. WTF

This may sound dumb ... And wings is free to call me an idiot- but

Have you tried a build above 0.2 with that ss430?
Just asking, I don't use that wire - full disclosure

No I haven't. All of my builds with the 430 SS are always sub .2. This same build in tank I can move over to my lava box and it works just fine with no issues.

right, I was curious to see if the different board would be able to handle the larger metal mass a little better.

 

[MidwestExpress]

Is it because these are dual fused Clapton's? They are only two wire cores so I didn't think there was that much wire in the build they are 28 gauge cores though

[Wingsfan0310]

I'm not sure what else to suggest. It seems like for whatever reason that mod is limiting out to quick with the normal Curve/TCR for SS430. The quick fix would be to raise the TCR for SS430 in it. I'd start at .00140 - .00145 and work my way up. I'd rather change the TCR then have to keep unscrewing my tank to get the mod to lock a higher resistance.

I know that doesn't fix the problem, but it would make it vape better. Sorry I couldn't be more helpful!

Cheers,
Steve

Edited to fix the 0 I left out.

 

[MidwestExpress]

No worries and thank you very much you have been very helpful. Just trying to figure out this new mod is being a little bit more difficult than the last one.

[f1r3b1rd]

well, its a different board in a different case

for one, evolve is the most accurate thing on the market... with that accuracy comes the fiddle fucking until you get it nailed down.

we'll get it nailed down, it'll just take a minute.

I'm pretty sure the issue is either

A) mod resistance
B) the metal itsel
if it were me, I would double check that I am on the newest firmware that fixes 316. and try building with 316 to see if that could possibly resolve it

 

[MidwestExpress]

Ok, sounds like a plan. I was going to order a bundle of kbee ss316. I will go ahead and get that and try a new build.

What type of builds are you guys running on the dna75's? I have a second conqueror tank I was going to use until I buy a Mage. I do also have an old school Aromamizer I can build out. It has basically the same build in it right now.

Thoughts?

What gauge wire? I need to rebuild my v2 petri. I have acted one so it will look good on the red nano.

I had thought about seeing if I could put a single 3.5mm or just a 3mm fc in my second Conqueror. I have the room with it being post less.

it is damn good wire.... its just not pretty is all.
but it kicks some ass.

I tried 430 a while back, but got a bad batch from "crazy wire" in the uk, after that I went full on 316. I bought a few hundred feet of claptoned 316 from avs.

 

[MidwestExpress]

Yeah, I want to snag up some 316 that is better than kbee but you can't beat the bundle price. 24-40 100' of each gauge for $26 shipped. Not the cleanest wire but it is still pretty good wire.

hmmm.... with the dna being as picky as it is for a mod, I figure the few bucks more for wire is worth th expense.

especially after having to rub down ni200 with an alcohol wipe back when the dna40 first hit the market.
- that shit got old FAST

 

[mackman]

A couple of ideas. On the DNA75 I have found it helps immensely to run the Case Analyzer in Escribe more so it seems than with the DNA200.
As far as the mod resistance take an old carto remove the coil and fill the 510 end with solder or take a 510 to 510 connector and fill one end with solder. i have found they both will give an accurate mod resistance reading.

That is a true thought! I will probably just order some from advanced vape supply. I have been wanting that vertibraid after all! Get some FC wire too.

I wish I had something old to do that with! I think when my kids hit the sack tonight I will take an old rda and shove some cleaned up 12 or 14 gauge copper into to make a resistance tester. Might not work out too well though. Might give a bad reading with too much resistance...

[MidwestExpress]

So I used a base off of a Griffin that I had extra laying around, and shoved 12 gauge copper into it. I get a reading of .008-.009... That seems way high so I am thinking that my make shift calibrator is not gonna cut it...

 

[MidwestExpress]

If I have the mod plugged in and escribe running with no atomizer or anything connect to it and I click atomizer analysis... it shows:

cold ohms: ?
raw ohms: .036

 

[MidwestExpress]

So as a test, I changed the internal resistance setting to .0089. No more temp errors. No more needing to pull the tank off and back on and saying yes to a coil change of higher resistance.

One thing I noticed is the Nano gets hot now. A couple pulls on it with in a couple mins is causing it to get warm.

Is that because this is a single battery mod and it is just taxing the battery on that level? My temp is set to 400 and my watts are at 70. I probably just need to put a smaller build in it I am guessing to control the temp of the mod right?

 

[Wingsfan0310]

I think those boards get hot when you push them to their limit. I use mine at between 30-40 watts in TC and it's not too bad.

The DNA200 boards seem to run cooler. I like my Lavabox75 but still prefer the DNA200 board. The reason I think the DNA200 boards run cooler is because they are more efficient (97% vs 85%). The less efficient board will throw off more heat.

Yeah, that is a big difference. I do love my DNA200 much more. Got the DNA75 for a pocket mod when I am out places and don't want to walk around with the big dog and not wanting to throw clouds around. I need to build smaller but not lose the flavor. Drop that power use way down!

Just thought it was wild that everything I have read or seen online says that the internal resistance is normally never above .005 and mine is functioning like I think it should when set to .0089. Could I have a mod with some internal issue causing this or is this just a luck of the draw?

 

[Wingsfan0310]

I don't have that particular mod so I don't know for sure. I do have quite a few DNA mods though and the resistance ranges from .003-.007. The difference you are seeing is less than two 1000's of an ohm. That's really not much in the overall scheme of things. I tend to think it's more just luck of the draw. Like I said I don't have that mod though so it's just an educated guess.

Cheers,
Steve

 

[MidwestExpress]

Well it works now and only because of the help of the people here! Thanks again for helping out on this issue!

Now I will just work on building a low power set that can still lay day some good flavor.
