I'll try my STmini with ni200 OCCs on my Waidea to see if I have issues. My Waidea is 100% stock, haven't done a thing to it. I'm guessing I probably will, as they don't even work well on my real DNA40. I'll report back my findings shortly.
I can use my ST Mini fine on my Waidea for non-TC, but have never tried TC. Yeah that's what I heard re TC on the ST.
@diceman1000 , do you have any nickel wire? If you don't have any separate RBAs, one thing to try would be the RBA section of the ST mini as I believe that might work a bit better - I understand that most of problem with the ST Mini is the Ni200
coils themselves. So the RBA may well work better.
And if you do have both Ni200 wire and separate RBAs, then definitely try those together as well - in fact I'd try a separate RBA before even the ST RBA deck, if possible.
Remember, spaced
coils when doing Ni200 builds - no coil touching any other. Plenty of build videos available on YT.
At this point there's no reason at all to think anything is wrong with your Waidea. You probably just need to use it with different attys for TC, or at least use the RBA deck instead of Ni200 coils.
ThunderDan's testing will give us a bit more info. I can't do the same as I have none of those Ni200 coils. I could try a Ni200 build on the ST RBA deck later, and will if that still seems like it will be useful by then.
