Temperature control coil building help required

[VapingBad]

If it is working then if you progressively reduce the temp after a while each reduction will reduce the amount of vapour, don't assume it will be noticeable at medium and higher temps though.

That Bellus is weird What`s that big hole for?

[charliehorse]

TallPaul70 I thought it was a good idea myself as well till I saw the youtube video of the guy doing the scorch test with it whacked up to the full 75 watts
Thought I'd deleted the post before anyone saw it.

Also in the video as well as having it on full wattage and 400 F, the cotton he uses is bone dry so it's a mystery why yours only seems to work with juice in it.
Been reading up a lot on TC myself recently and I notice people really recommend securing the (nickel) wire under the screw head rather than in the post holes.
Other than that I'm at a loss.

Got a VTC mini on the way myself as well so I'm also hoping it behaves itself

Cheers VapingBad, there's a big difference in vapour production between 300F and 420F, so guess that confirms it's working OK.

Just no idea why not when no juice in, but maybe I should just let that go

The big hole on the other side of the build deck?

There's an adapter that you stick on that side when you just use a single coil, it attaches into that hole and basically blocks off the juice channels on that side and essentially fills the whole space on that side of the atty where the second coil would normally be. The Goblin Mini has the same type of adapter, it seems to be a Youde thing.

Overall, I'm really impressed with the Bellus, it's a nice tank. It's just physics that's p*ssing me off

Yeah I've used the screw heads rather than post holes on the other atties I've tried building on (Lemo 2 and TFV4), but with the Bellus the posts are quite high and I'm not sure it'd really work, bit leggy...

Thanks anyway mate, it's a total bloody mystery to me, and I don't know enough to know what I might be missing.

But my basic thought is, leaving aside functionality when actually vaping, all that should have to happen here is that the resistance needs to be high enough for the mod (which it is) and locked in at room temperature to give a starting point (yep), the coil not touching the deck anywhere stupid to cause a short (all good). Then the mod should be able to detect the resistance change as the temperature changes and adjust to regulate.

If it's doing that when fully built and juiced why should the same not apply when dry... the temperature is still changing (and so the resistance)... I suppose it could be happening quicker when dry and without the airflow caused by vaping, but I'd doubt that would be significant enough to prevent the chip from keeping track...

Nah, I'm clueless It clearly doesn't happen in all cases, the vid you posted shows that, so effectively my mod is faulty, but only if I try to test it, not when I actually use it.

My only real concern is that if I run a tank dry I'm going to end up dry hitting, not a huge issue but removing one of the benefits of TC.

Ever wish you'd never started something?

That would drive me mad  

decoy had the same problem - have a read through this thread allaboute-cigarettes.proboards.com/thread/57790/ni-200-wire-probs

-and was going to send his back, but I don't know the outcome.

[decoy]

it drove me nuts and i ended up with a replacement that passed the dry burn test 1st time
TallPaul70
the easy way to test is to have 2 of the same mods and try the same atty/build on both
i only really knew mine was faulty because i have another tc mod that is known to work ie burns dry cotton at about 430
so if you know anybody local to you that has a tc mod see if they will let you try a dry burn test ,rem it dont have to be a dripper you can just use a tank thats not fully built

other than that i do drive so if you get really stuck give me a pm and we can sort summut out

my faulty one did this which is why i had a little fun changing it as the shop tech said it was fine
till i messaged them to vape the tank dry
funnily nuff i got a message back the next day saying new one was in the post,i guess it wasnt a nice dry hit

Ah, you're a top man, decoy, cheers.

Reading through your previous thread and what you've said here it does seem to be exactly the same as what twisted your head and has been twisting mine now.

I've got an X Cube II as well, and the temp control 'seems' to be working on that, at least the screen is showing it activating while I'm vaping, but when I tried the dry burn test with that, I couldn't get the cotton to scorch even at 600F... I haven't gone back to think about that yet, just been trying to work out the Sig.

Anyhow, I've got an eVic VTC mini on the way that should arrive any day so as long as that works I'll be able to use it to double check everything, but based on you having the same problems I'm more inclined to try and send the bugger back and get a replacement, there must be a faulty batch or something, and even though the TC works with juice now there's no guarantee that will continue.

Ah, he'd said he had a faulty one but I didn't realise it was quite so exactly the same problem, that's really interesting, cheers charliehorse.

That makes me more inclined to try and arrange a replacement, TBH, but I think I'll maybe wait till the VTC mini arrives.

[robby]

I have two Xcube2s. I`ll do the burn test with both but as far as I remember it does burn cotton but up in the 550F region.

[robby]

That`s the 2 Xcube2s set at 600F and not fully burning but getting as near to burning as is necessary. The coil is reading .08 ohms on both. So one is charring a little more than the other but not an issue, they are near enough the same. The TC-NI setting is at default 0.00600 on both. I dont think there is a problem with your Xcube2. If you were to turn up the TC-NI setting to 0.00610 you would see a difference and (if my brain is in gear) some charring/burning TallPaul70

[TallPaul70]

That's great robby, nice one mate, I really appreciate you going to the trouble of checking that out for me.
