I've seen a number of posts about 'weak vape/no flavor/no clouds' and the like.
I got into TC when the SX Mini M was released. STM with both V1 and V2 build decks.
Thinking the recommended values would be the best for the device, I rolled a couple of Ni coils and got to almost .015 ohms.
Real lousy vape at any Joules/Temp combination.
So, I think, 'It's the wicking' and away I go trying different thickness, length, fluff, etc.
Not getting any thing except plenty of practice wrapping coils because the Ni was SO easily deformed pulling the wicks.
I dropped in some Kanthal prebuilt coils and they vaped fine. Along came the Ti test firmware, so I chucked that into the M and tried Ti.
That was somewhat better, but not great.
Along the way, I must have 'Done something', because suddenly the STM was vaping like a champ! Great draw, great flavor, great vapor!
I of course thought it was the wicking and that the coil/wick just got 'broke in'. So I duplicated the build on another STM and put it on.
Nope, not even close. Lousy in every way.
Then I put the other tank back on, and set the resistance as you do when switching tanks. It read .53!
The other read .26
So, I wrapped 28 gauge Ti on my trusty machine screw, a 6/7 wrap (meaning I have 6 full wraps with a 7th starting) and I get a .48
This vapes MUCH better, and I have 4 tanks coiled the same within .02 of each other. All vape quite well for me at 18-22 J and 170-190 C
My empirical evidence is that a higher resistance equals better vape for TC using Ti.
My 6/7 wrap is the most I can squeeze into the STM and I think I'd get a slightly better vape with more resistance.
Anybody with Ti wire to try higher res willing to give it a shot?
I am convinced this is the reason for my lousy experience early on and the good results now. Works the same on the D2 and the Mini M.
