Hello! I'd like to suggest a feature that would be incredibly useful for those using AF devices for various ceramic heating element and convection atomizers. With these atomizers, temperature control modes often either require extended warmup periods or pulsing of the fire button to make sure the material to be vaporized doesn't get too hot. This could be largely solved, however, if there was a setting allowing a "temperature overshoot" at the beginning of a hit, or setting the target temperature of the ecig coil higher temporarily at the start of a hit. In essence, the problem with these atomizers is that the coil that we're temp controlling is having to then heat up another medium (the ceramic/air), whose temperature we can't measure. If we just set the heating coil to the desired temperature of the ceramic dish/air, it'll take a fair amount of time for the actual heating medium (ceramic/air) to actually reach that temp, meaning we'll have to deal with extended heat up times in excess of half a minute in some cases. If we instead set the heating coil to a higher temperature, we will reach our desired temp with the heating medium a lot faster, but the heating medium (ceramic/air) will then continue to heat beyond our desired temp, causing the user to have to pulse the fire button to prevent the material from combusting. The solution then would be a hybrid of these two options, where the device operates in temp control mode with a "starting temp", then after the coil has been held at the starting temp for some time, the power would be decreased significantly and the temperature setting will be lowered for the remainder of the hit. This would allow for the fast heat up times in the second example above, while also allowing users to take extended hits without concern for overheating the ceramic dish/convection air. Now, this would definitely take a lot of guesswork and experimentation to configure for each use case, and this would venture well into the territory of using the "temperature" value more as an arbitrary variable than an actual reflection of the ecig's coil temp. I fully admit this feature would likely have no value to those using their ArcticFox boxes solely for traditional cotton wick and coil vaporizers. However, for those of us using our AF boxes for atomizers where the metal coil is being used to then heat a ceramic dish or other heating medium, this additional feature will allow for even more fine tuning and customization, in the same way that the advanced preheat curves of AF allow for more fine tuning of traditional vaporizers than an absolute preheat. I will admit, this feature does already sort-of exist in a roundabout way, in the form of custom Preheat curves, although in that case through limiting the output power at various time points. While this does a good enough job of further diminishing the power later in the hit, the feature I suggest with a primary and secondary temperature would make it easier on the end user to configure this sort of setting, since they could use temperatures they get from testing in normal temp-control modes. For instance, the user could get their desired secondary temperature value by experimenting with the normal TC mode at low temps with extended heat up times, then find their primary temperature by finding the lowest temperature setting in normal TC mode that gives them the heat up times they desire. This process would be easier and clearer than having to set up the custom power curve currently required. TL;DR feature request, allow for setting target temp lower at a user-specified time during puff. Not intended for standard ecigs, more intended for ceramic and convection atomizers where there's a lot of delay between the coil heating up and the desired material to be vaporized heating up. Feature is technically already possible but only through workarounds EDIT: Quick update with an example of roughly what I mean simulated using the aforementioned curve setting of Preheat. In my case this was a custom curve set to 100% power for the first 6 seconds to account for the initial ramp up time, followed by a sharp drop to 65% power to account for the drop in power output after the coils reached temperature normally, followed by a slow rolloff to 54% power output throughout the remainder of the hit. (20 second timescale for the graph) Since this atomizer uses a ceramic heating dish under a titanium bucket, this temperature curve results in the bucket heating to the desired temp more rapidly, then being held there without overheating as the ceramic heating element has the heat backed off gradually. Implementing this using a custom temperature curve required fiddling with the curve 20+ times while taking hits and checking the results in device monitor to finally arrive at this rough desired curve, while trying to implement this same curve with the feature I requested in the above post would simply require setting the starting temp to 510, the final temp to 455, and the switchoff point at ~8 seconds. Note also that other atomizers will require the coil to be held at the starting target temp for much longer than seen in the example image. Another element I wanted to clarify: This "temperature overshoot" should have a short timed "relax" feature for when users press the button again after a hit to apply heat for longer, similar to standard preheat relax timers. In this case you wouldn't need an overly long relax timer, likely in the range of 10-20 seconds, since the heating medium in most of these atomizers rapidly heats to below 250 degrees fahrenheit after just a few seconds without heat being applied. If the user does wish to press the fire button again immediately after ending a puff, the new puff should start with the "finishing temperature" from the previous puff, to prevent a sudden spike in heat with the start of the new puff.
