Re Lavabox micro USB. My USB does not go all the way in the Lavabox either, nor does my buddies. From what i have seen the USB connectors are all the same on the Lavabox, in fact a number of my devices are the same including my M Class, the USB does not push in flush with the device. Just be gentle when inserting or removing the USB plug from the device as not to put undue strain on the device USB socket. As a side note, how is everyone getting on with the Lavabox, any problems, quirks or annoyances?

If that is the case, then my calculations are correct and correlate with Volcano's data, that is my Lavabox does indeed read around 0.02 ohms to high before mod resistance adjustment, i have done my own experiments several times both shorting out the 510 with a 7x0.5 brass bolt and using different atomizers as reference and the results are always the same, around 0.02 ohms, maybe Volcano's numbers are correct after all. I agree with the previous posters comments, if you are unsure just leave the mod resistance at 0 and err on the side of caution.

After pestering my friend yet again (who is an electrical systems design engineer in the aerospace industry) and showing him the DNA200 and escribe in detail, his conclusion is that due to the small tolerances in deviation, fine measurements and the number of variables used in temperature control with the DNA200 (and temperature control vaping in general), many of the user settings such as case temperature co-efficients and mod resistance settings would be difficult for the home user to get accurate outside of laboratory conditions. Although I am no expert in electrical or thermal testing I would suggest this why users are getting different results from each other within their own tests (is everyone using the same test equipment and methodology?) especially regarding case thermal analysis and mod resistance, of course I could be wrong. Again I feel that device manufacturers should have done the research before the release of the devices themselves so that every thing would already be in place and users would not be having to hunt around for device specific settings. I know many of my vaping buddies who have also been vaping for many years, and who are also owners of various DNA200 devices, tend to agree. I'm not bashing Evolv or the DNA200 in any way shape or form, Evolv are a decent company and the DNA200 is a great board, but I feel that many of the device manufacturers have not fully done the ground work for the release of their DNA200 devices. Even after using relatively high end gear such as my friends Fluke meter and oscilloscope, I am still not fully confident in my own findings, or the manufacturers numbers regarding accuracy, even though the settings seem to be working fine at the moment. I agree with Rune, that perhaps there should be independent tests done preferably by a certified electrical test laboratory to confirm the data being released by device manufacturers as this would give us a better idea about the accuracy of device manufacturers data in general. My advice to anyone who is uncertain about the data given by Volcano or any device manufacturer at that regarding the DNA200 would be to leave the settings as per Evolv default. Make sure however that you have put your battery data correct as apparently that is one of the most important settings to have right from the get go. I think that this is a topic that will be going on for some time yet, until we can be confident that the numbers we are given by the manufacturers are correct. Apart from keeping on to device manufacturers to provide validated data, I don't see what else we can do. The choices at the moment are, use Evolv defaults, use the numbers from our own tests (even though they may not be accurate) or use the numbers provided by the device manufacturers (again these may not be accurate), you pays your money and takes your choice on this one i'm afraid to say. In some ways I can see why so many mech users still love their 'simple' mods.

Like I said before, that's the info i got back from Volcano. Don't take it as gospel and use the settings at your own risk. Although the numbers are working for me, they may not work for everyone. Personally using other mods, my friends Fluke meter and his oscilloscope my resistance readings are around 0.02-0.021 ohms high on the Lavabox, (before mod resistance adjustment) which goes to show how great the variance of readings can be from person to person, device to device. Again I agree that this does seem on the high side. There are so many variables when dealing with such small resistances that getting truly accurate results at home may be hit and miss, therefore the only other option is to rely (and trust?) the numbers supplied by the device manufacturers themselves. I think that there is still a lot of research to be done by device manufacturers on the DNA200 and temperature control in general, research that I personally feel should have been done and released before the release of the devices themselves. To be fair though, from what i have gathered from users of other DNA200 devices, Volcano are not on their own on this. All users can do is keep asking the same questions and sit back and wait, however I will be firing another email off to Volcano questioning the validity of their data, and why the mod resistance is so high.

I have received the following information in an email from Volcano customer support regarding escribe settings for the Lavabox DNA200. Battery - 9.99wh Mod Resistance - 0.02 Case Thermals (top to bottom in escribe) - 489.94 374.17 8.09 11.88 -20 110 I have punched the numbers in for my own Lavabox and everything seems fine. I agree with previous members comments that the Mod Resistance figure of 0.02 does seem on the high side, but after conducting my own experiments, all of my coils read around 0.02 ohms high on the Lavabox (according to other mods and resistance meters) before using the above figure, after using 0.02 all my coils are reading pretty accurate on the Lavabox. I also found it necessary to lower my power in temp mode after using the above numbers. Although the above information worked for me, remember to use them at your own risk, although I doubt that Volcano would risk putting out iffy information. I hope that the above information has been helpful to other Lavabox owners.
