Screwdriver cart HELP

[Jdunn20]

Hey all, I recently received my SD and I am having a hard time getting it to wick. After some research it appears that there are two cart models being used: RN4075 and DSE 901.  The cartridges that are pictured on the SD page are RN4075, but the cartridges I received in box are for the 901, which is 2mm shorter from what i have been able to find. What do I do to get this to work properly? I don't want to damage the atomizer by using it when the filler doesn't make contact with the bridge!

Thanks

If you're worried that the cart isn't long enough (I can't comment - I'm out of practice with 901s,) you can bridge the gap by fluffing the filler up until it's a couple of mm proud of the cart lip. The bridge will push it back into the cart if you overdo it, but at least it will then be making contact.

And hi, and welcome to the forum!

Hey thank you for the quick reply, I have tried fluffing the filler as well as adding to get the height difference the problem with that is without the sidewall the juice gets sucked through the mouthpiece.  The SD uses a RN4075 atomized instead of a 901 and is just slightly different.

Forgot to mention if you look at the sd page pic there is a brown "extension" piece in the cartridge like it is two pieces, as opposed to the one pice 901's.

If you're getting juice in your mouth, then it sounds like the cart is too wet - this will reduce vapour also, since the coil won't be able to heat up enough with a larger volume of liquid sloshing about around it.
It takes a bit of practice to know how wet is wet enough, but try blowing the atty through (from the threaded end,) to clear any excess, and replacing the cart as it is - that will reduce the excess volume of juice in the system, and if it was too wet, it should be at least not too dry once you've done that.

Yeah - that's the 4075. I much prefer the others ( I use 901 carts with my titan, because as an ex-pipe-smoker, I prefer a whistletip I can clench in my teeth.) They both fit a 510 quite well (though the 4075 is usually a bit tighter a fit.)

the problem isnt wicking its flooding..quite a common mistake.. once flooded it stay flooded... the user thinking it not wicking keeps adding more and its flooded for ever..

leave the cart filling out.. use an empty mouth piece.. at least ten good draws should be got with no cart fitted at all.. then fit the pre-filled cart and start again...it should all work.. when topping the cart up do not add a couple of extra drops into the atomizer for good measure.. this is usually where the problem starts..

i always seem to flood my 901 as well....thx for the tips

[Jdunn20]

Trog, I did you as you suggested. On the first attempt to vape, without any filler in the cartridge, I got nothing, same for all other attempts.I looked inside the atomizer, pressed button, and got an instant glow. Attempted to blow atomizer out onto a tissue and no juice is coming out.I inserted a prefilled cartridge (not pooled just slushy) then I attempted to vape...nothing time and time again. I checked the cartridge and it was dry, refilled just to slushy again...same again. I did not drip on atomizer at all. I have been repeating process for some time now with same results. I also checked atomizer and still instant glow, but no smoke. I attempted this with fresh batteries, and both atomizers that came with it. Please help!

And from the earlier post, I reread what I put and may have not explained it to well.  The cartridge in the picture on the screwdriver page is the one with the brown extention, the ones I have are solid black ones that do not have the brown piece.

Hiya Jdunn20, welcome to the forum. Sorry you are having problems with the Screwdriver. I have used both 2-piece 4075 style carts (looks like a wide 8 ) and 1-piece 901 style carts (Looks like a D) quite happily on my SD, also round and whistle tip 510 carts (looks like a 0) as well. As long as the cart is pushed fully home they all work. There is a noticeable click when the 901 carts are pushed home. You say that the cart is drying, so it must be going into the atty? With the cart in place, if you twist it round one full turn in the atty and then lift it out has the filler been disturbed? If it has the bridge is in contact. With the D shaped 901 carts the filler does need to be right to the lip of the cart. As to why you are not getting much/any vapour, what juice are you using?

[Jdunn20]

The cart is all the way on and i believe it is making contact with the bride, but still not really any vapor and a real dry taste.  I am using the juice supplied with the SD and 3 different kinds from tasty vapor (on sep atomizer) but same effect from both.

[StevieD]

In that case Jdunn20, I don't know what the problem is... I am sitting here using a D shaped 901 cart in a 4075 atty on my Tornado and it is working fine. Your atty is heating, your cart is getting dryand needing top-ups, it sounds like it's working fine, all i can suggest is gettin in touch with TW Customer Service and explaining it to them, see if you can get some 4075 carts?

If you blew out the atty and nothing came out, maybe its too dry and needs dripping. Try putting 4 drops into the atty and then stick on the cart.

[Jdunn20]

Attempted a couple drops on the atty...2 wisps of vapor then back to non existant.  I attempted to check the attys using a voltmeter: both atomizers came in at .5 ohms where my 510s ring in at the normal level.  This was a little odd because i thought they should be around 3 ohms. i dont know im lost, could I have got 2 wimpy dud attys out of box?

It's possible. Unlikely, but possible. And given enough combinations, you're bound to get 2 duds in a row eventually. Since you've measured them with a meter, I guess it must be so (not got them in front of me, so I can't really say.) IF they're measuring 0.5 ohms, then that's definitely not right AFAIUI (but I'm no hardware expert!)

[Jdunn20]

Iv attempted everything I can think of, I do not believe it is the atomizers they work much better without the cartridges.  I have watched multiple videos and the only difference i can find is with the cartridges.  The solid black carts just dont seem to be doing there job.  Every video or picture i can find, all have the two toned black/brown cartridges.  To the people responding, that use the screwdriver, do you have the black/brown carts or solid one piece black ones?

Thanks for all of your responses and help so far!

[StevieD]

As I said above Jdunn20, I use 4075, 901, and 510 carts quite happily in my SD and Tornado's with 4075 and 901 atties and have not had a problem with any of them, but you may be better off contacting TW to get some 4075 carts.
Hope you get it sorted.

okay one more go... the atomizer should come pre filled from factory lets forget carts completely..

take one bone dry 901 atomizer.. then pre fill or prime.. this takes about six or so drops of liquid.. the factory should have already done this.. all the user should have to do is insert cart and off they go..

without the proper pre fill or prime the thing will not work.. i think this is what i have just seen described.. an unprimed atomizer or one that has had all the fluid blown out and not enough put back..

so put six drops of fluid into the atomizer.. if it really is dry two is not enough.. they hold six drops.. two wisps is not what a correctly primed atomizer should produce..

now  forgetting wicking or other complications add some fluid to the atomizer fluid it if you have to... take it so it dosnt glow but sizzles.. this is a flooded state press the button until it does start to glow.. you are now a direct dripper... at least ten good draws should be got simply from the atomizer with no cart fitted..when after the vapour starts to drop off add the correctly filled cart and off you got..

okay i was assuming the common problem... too much liquid.. you seem to have not enough.. get it all going without the cart.. it should all work perfectly without the cart..all the cart does is keep it all going longer..

two wisps is just not right even for the atomizer on its own.. they hold six drops of fluid.. two is not enough if they really are bone dry the only way they can get bone dry is if the user blows all the fluid out.. when you blow a flooded one out you should gets lots of liquid out of it..

okay i got it wrong the first time.. but there really are only the two options here... too much fluid or to little.. he he

trog

ps... the important bit is it should all work without the cart.. simply not for so long.. it works out roughly to three very good draws per drop of fluid.. up to ten draws from an atomizer on its own.. up to twenty with the cart added.. rough figures but in the ball park... two wisps isnt even on the field....

Trog, thank you for the response.  I followed your instructions, and everything works up till adding the cart.  Wonderful hits off the atomizer but once i put a prefilled cart, i get about 10-12 good hits, then the atomizer is dry and the cartridge stays full, and i lose all vapor, unless i take a REALLY hard drag.

What is your experience with the single color carts? Is this the problem?  I have them filled correctly, and the filler is fluffed and flush with the top of the cart, but im not getting anything from them.  After I vape what the atomize holds, I get nothing!

very rare but you could have a cart with a blocked up hole.. we did come across one the other day..

fluid should transfer from the cart wool to the wire wool bridge in the atomizer.. you have two sponges.. the atomizer wire wool sponge which holds six or so drops most of this stays in and dosnt come out unless its blown out.. then you have the cart nylon wool stuff..

together they hold around 16 drops... around 6 to 7 drops of this fluid is usable.. the rest stays in.. this is with a nice new-ish cart..

the length difference between the two types of cart isnt that much and both should work if the wool isnt pushed too far down.. the cart wool does have to touch the wire wool bridge..

long slow drags are the way to do it not fast short ones.. the air hole inj the atomizer is small and you cant force it..

you are getting there.. just dont empty the atomizer sponge as much before fitting the cart sponge .. what you are after is both sponges working as one..

6 or 7 drops at three good draws per drop works out around twenty good draws per top up.. 6 drop per top up is good.. this works out at roughly three top ups per ml of liquid for good results....

trog

ps.. as the carts age they get greasy and wont take or give up liquid as well.. they need changing every few days..thinner liquid works better than thicker liquid.. it does vary..
