Like the title says I am never asked for new coil, UNLESS I use the same coil. For instance if I unscrew my kanthal tank to refill, reattach in 30 seconds I am prompted with the new coil message. If I switch to ni200 or Ti, I never get the message and the device usually fires in power mode. I have a profile set for ni200 and titanium and I'll switch to that profile first, attach atty and it will fire in power mode. I've had the device ask me new atty a number of times, I'd say 10% and even though it's a TC build the device refuses to run in temp mode. This is my first dna 200 chip, but I'm very experienced (6+years) so I feel I am missing something. I trust the chip and the device(wismec reulaux) but what is the common denominator here? I've watched loads of videos and followed certain procedures to a T. As far as my build I recognize it could always be a problem but the device should adhere to my profiles correct? I would say 75% of my atty builds are spot on. EDIT- Just attached a brand new ni200 dual wrapped at .009...I was asked if new coil selected, yes and I was already set to my ni200 profile. Temp control is NOT active device monitor shows zero temp activity and the mod itself cuts off temp when fired. This has has happened for 6 straight days now on every type of TC build. All gauges of ni200, TI, claptons etc....I'm desperate here. I do not get a spike in device monitor for the temp reading, it simply will not function
