Currently using 26Ga SS316L .5 Ohm in temp mode (temperature dominant checked) at 420F and 35watts. I'm using .5sec preheat with preheat power set to 125%.
I'm using 316L TFR and only use 2 profiles at present. One for round wire builds (my general preference) and 1 for claptons which I play around with from time to time. While TCR is fine, I find the TFR more fexible for my use. For round wire it really makes no difference with the exception that it is easier to use a coefficient since it's a single number for the user. But there are use cases to be made for being able to manually massage the curve with TFR. For example, when I use any type of clapton coil with dissimilar metals I like to adjust the temp to resistance of points 2 and 3, leaving the remaining curve alone. This gets rid of the irritating small bits of spit back during initial firing, yet has no effect on the actual temp I vape at. This was the only way I was able to cure the very minor spitting, maybe it could be better characterized as more of a popping sound, without resorting to a lower temp, cooler vape, or lowering the wattage and inducing longer ramp up times. There may be a better way and I just haven't found it. I'm only talking about the first .5 sec or so after pressing the fire button and only with claptons. It's not needed for round wire builds.
I haven't had the need to use regulation with PI really. The easy way to tell if it would be helpful is to use the live monitor and vape normally. If the temp and power are oscillating the PI regulation is a good tool to dampen that. P (proportional control) realtime look at the regulation occuring and can tend to overshoot or undershoot needing to correct for those conditions. I (Intergal) is a way to dampen P when it tends to go a bit off track since it it basing it's evaluation of performance of the regulator in the past... very recent past measure typically in micro seconds. it keeps track of previous behavior of P. Based on this, it can dampen the overshoot before it happens, at least that's the theory. What it's missing for best control is D (derivative) which is the predictor of the future based on the results of both P and I and is that last needed data to create an actual closed loop system. Long story short, watch the realtime monitor while vaping and if oscillations are there use this tool to dampen that. If the trace looks smooth it's really unneeded.
I probably rambled too much. That'll teach you to ask me tech stuff right?
One last thing you might be able to help me with
@AngeNZ. Where is the control to turn off the light show. It irritates me that I haven't been able to find this if it exists. I only use the mod at home so it's not a huge deal and I could physically disconnect it inside the mod I guess. But if there's a way to do it that I have missed I would be grateful for the method.
