(To get to the recording, go to Device Monitor -> History -> Download All Recordings). It looks like a current offset issue, to be honest. @James I don't know enough to follow your reasoning, but here's the screenshot of the puff#1774 once I downloaded it in Escribe. I've put a pair of peak/valley cursor for you to see the TEMP/POWER levels Link to comment Share on other sites More sharing options...
James Posted June 16, 2017 Report Share Posted June 16, 2017 Howdy @ndb. Give this firmware a try. I think the issue is current offset when it's down at 0.5W. In Serial Terminal, X=GET COB gets the current offset. It is 0.025 by default on DNA 75 Color. On a DNA 75, it is 0.0625. Try X=0.0625 COB and see if it fixes the oscillation. I suspect it will.

lordbyron77 Posted June 18, 2017 Report Share Posted June 18, 2017 Here you are two 75C with beta2, I let them rest all afternoon. I would say that the error is acceptable 👍 29°C at home (Chinese thermometer LOL) 31.8°C MTO DNA75C 30°C Reference box 1 Link to comment Share on other sites More sharing options...
retird Posted June 18, 2017 Report Share Posted June 18, 2017 My 75C after setting all day is reading Room Temperature @ 72.09 F and a Digital Thermometer is reading @ 71.4 F...... and not using the beta2p2.... 1 Link to comment Share on other sites More sharing options...

Thanks! DNA 75 Color v1_1_SP22_Beta2p2.sw-service Hi @James, sorry for the late reply but I've been again on the move and couldn't access Escribe until today. Whatever this setting is doing, it works! I just got a bit confused initially because it seemed like it worked just "for a while", then I realized that after a while (maybe when the device locks/unlocks or when I reconnect to Escribe?), the setting reverts to 0.025, as confirmed by X=GET COB. I couldn't really nail down exactly when/why, but I then started to always setting it back to 0.0625 before testing and then I got repeatable results. For comparison, here are two consecutive puffs, the first with 0.025 and the second one with 0.0625: COB=0.025 COB=0.0625 I hope this is what you expected and gives you all you need to maybe prepare another service pack which makes this a permanent setting? Eagerly waiting for your feedback, thanks again. Link to comment Share on other sites More sharing options...
James Posted June 19, 2017 Report Share Posted June 19, 2017 Yes, the debug setting doesn't retain after power-off. It looks like the steady state power is different slightly. Am I seeing that correctly? Also, could you try an in-between value such as 0.04? Link to comment Share on other sites More sharing options...

I didn't notice it but the steady state power for COB=0.025 is about 10W, while for COB=0.0625 is about 15W. Both puffs were taken with power set to 16W, TEMP=400F, pre-heat 32W 395F. I tried with COB=0.04 and I got this COB=0.04 The "first" steady power is ~15W (as you can see from the cursor), while the "second" one is again down to ~10W. Tried also with COB=0.05, got a first puff still pulsy, then the following ones were pretty much like COB=0.0625 (with steady power ~15W), but it felt like it was less repeatable and on the verge of pulsiness... As a side note: while on COB=0.0625, for a couple of time I got immediate "temp protection" when trying to fire. Then at the 3rd or 4th attempt it started firing again.

Nicolasan Posted June 26, 2017 Report Share Posted June 26, 2017 With the SP22 Beta2p2 is much better but still have some problems. Expecially if I leave the Device in stand by for long time. About the Room T something is wrong! Sometimes (expecially when connected to EScribe) is corresponding. But on other moment, like now, with the device not used during last 10 minutes(and the device is not warm at all) it's reading a 35 Celsius against a 25 real room temp! Tryed a couple of time the Case analyzer but not changing a lot! Any news or next firmware releases coming? 1 Link to comment Share on other sites More sharing options...
John B Posted June 26, 2017 Report Share Posted June 26, 2017 When I hand-tuned thermal parameters, I got 20 degrees F per amp and a 12 degree offset. Try those values and see what you get. We'll have a new firmware in a few days, finishing up the Mac version right now. 1 Link to comment Share on other sites More sharing options...

I'm looking at this thread several times a day since my last post on June 20th, hoping to see something new popping up. Sadly I've had to shelve both my therion and vapedroid 75C at the moment since Temperature Controls is simply not there. Tried 3 different atomizers (Kayfun 5, Kayfun 3 mini, Squape X) with 3 different SS builds and none of them performs on the 75C in an even remotely comparable way to the 200 (evolv reference, vaporshark) and/or the straight 75 (smy 75, hcigar nano). It's either a weak vape at my usual settings (~18W, ~400F) or it is badly pulsing (unless I first program that X=0.0625 COB parameter, but that is lost after some idle time). I do really hope a new FW will make the 75C the board it is expected to be, and that I love for all its features. 2 hours ago, John B said: finishing up the Mac version right now. Well, that would be more than awesome! I'm counting the days I can get rid of this "for-escribe-only" windows VM And now I'm going to wear-out my "refresh page" shortcut.

67exec Posted June 28, 2017 Report Share Posted June 28, 2017 @James, I have noticed that my 75c seems way more accurate on ohms and temp with heavier wire. My OBS engine has been my go to tank as of late, and I notice way less variations running dual 26g 316l at .32 than dual 28g 316l at .5, and even less when running dual 24g 316l at .3. I also get temps more consistent with my 2 dna 250s. Link to comment Share on other sites More sharing options...

I also get temps more consistent with my 2 dna 250s. On my side, I instead did a test with a higher TCR material, TEMCO Titanium 1, but with the same 26g as the SS316L I was using before, and in the same K5 atomizer. More specifically, the coil is a 3mm ID, 8 wraps, 26AWG Titatanium1, which steam-engine predicts @0.368 and that dna200 and dna75 report respectively 0.372, 0.374. Therion 75C reads as 0.356, Vapedroid X1C2 reads as 0.349. (both mods with internal resistance configured, and case analyzed: vapedroid by manifacturer, therion by me) I unfortunately can't remember the reported room temperature of such readings, but it always seemed somewhat higher than expected. Of course if I vape straight off those baselines I get a weaker vape, and if I manually correct the cold res value, than it's pulsiness galore... Also, I didn't investigate too much as I was already getting nic-buzzed, but it seems like with titanium, setting the 0.0625 COB doesn't have such a dramatic positive effect and pulsiness seems to just reduce a bit, but not disappear. But, again, take this with a grain of salt as I couldn't keep testing it for too long. I'll see if I have some more time later and test further, possibly reporting some screenshots... 1 Link to comment Share on other sites More sharing options...
Shinn Posted July 1, 2017 Report Share Posted July 1, 2017 Is the new firmware available yet?

Jonski Posted July 2, 2017 Report Share Posted July 2, 2017 I also have a Therion 75C and tbh I am really disappointed that I am coming here onto Evolves forum to look for answers instead of Lost Vapes . I have sent them an email to their support asking about the case thermals and their recommended settings so maybe they will get back to me . In the meantime I will be keeping a close watch on this forum to see, and pretend I understand, what transpires . For some, particularly me, the Therion is the pinnacle of vaping mods and it's only thanks to the miracle that is Fathers Day that I could afford it so it's disappointing not to have it working right out of the box . Same thing happened with my C1D2 but atleast VapeDroid had the settings posted to their Facebook page . TBH I'm only posting this extra bit for others like me that might not understand all the technical stuff and want something to read . Link to comment Share on other sites More sharing options...

As I said, I've practically shelved both 75C mods as TC is not at the expected-from-a-DNA top level. I now use them only to test/experiment and try help with the next firmware iteration providing as much feedback and information as possible. I do really have high hopes for the next iteration of the firmware, as I'm sure everybody at Evolv is doing everything to nail it down. 1 Link to comment Share on other sites More sharing options...

wintergreen Posted July 5, 2017 Author Report Share Posted July 5, 2017 No the thermal settings don't make any real difference to it reading the resistance, Its a shame really because I really wanted to use the mod but instead its become a very expensive paperweight. Hopefully Evolve will fix the issue soon. 1 Link to comment Share on other sites More sharing options...
embe71 Posted July 10, 2017 Report Share Posted July 10, 2017 Any news on this? SP22 which comes with the Mac OS Beta of Escribe doesn't seem to fix it. Cold ohms are still a good amount to low when reading the resistance the first time. 1 Link to comment Share on other sites More sharing options...

Cold ohms are still a good amount to low when reading the resistance the first time. As I've reported in the mac-beta thread, it seems like SP22 does actually implement that X=0.0625 (actually X=0.063) COB setting that alleviates the pulsing problem (see my post above, June 19th). This is a step ahead but I can confirm I still feel TC is not completely there. Ohm reading is still on the low side and the interaction with weird room temperature reading / weird thermals is overall making TC sub-par in my opinion. NOTE: for weird room temperature reading I mean that sometimes is really spot on and sometimes not. Link to comment Share on other sites More sharing options...
Lowbytes Posted July 10, 2017 Report Share Posted July 10, 2017 @wintergreen cmon - your chipset is no china crap - all things will be sorted out and fixed - pretty sure we´re still on beta software so no expensive paperweight......

They need a bit more time! Sorry but when I bought my Mod I expected to use it, Not have it sitting on a shelf for 6 weeks because it cant do the job it was bought to do. Call me old fashioned but I still believe Beta firmware and beta testing should be carried out before the product goes on sale. When did it become the customers job to beta test products they have bought? Link to comment Share on other sites More sharing options...
Lowbytes Posted July 10, 2017 Report Share Posted July 10, 2017 100% Ack in doing beta tests before going on sale BUT - since we have this shitty TPD2 and the FDA regulations maybe there was no time left ............... We are all dreaming of perfect products - but in reality no products are perfect The differences ---- if you buy a low cost product you may buy it "as it is" maybe you´ll never have support and updates Here we have a good conversation - evolve is listening and trying to sort things out as fast as possible - for me the best service Yes - it´s a bit tricky actually - but it is working good - a bit low ohm reading so TC is not 100% accurate - but far better than nearly all other Chipsets! So for me no problem to stay tuned and looking forward for things to come! 1 Link to comment Share on other sites More sharing options...

wintergreen Posted July 22, 2017 Author Report Share Posted July 22, 2017 The new firmware bundled with the latest escribe version doesn't make any difference to it reading the resistance too low. The release notes say its fixed but it hasn't changed anything. Still reading too low for accurate temp control. Link to comment Share on other sites More sharing options...
