this is like my third dovpo riva dna250c, i dropped my last one and broke so i bought a new one i liked it so much. this one was working flawlessly until about a week ago. I use the same build on the same wattage with the same juice, constantly. a week or so ago i started getting a noticeable drop in vapor production and throat hit. I looked at the diagnostics on the screen and everything looked fine, but when i hooked it up to escribe and used device monitor, i get a competely different value for the current out put when i fire. than what it says on the screen of the device in diagnostics. On the mod screen, it says im get 38.3 amps when i fire. on escribe its says 23.3 amp. i restored it to default settings it doesnt fix it. can anyone help me. i wrote evolv a couple emails for help... havent gotten a reply yet.

So I need one wire to the positive and negative of each of the solder spots? Cause there's only one ground (-) spot on a dna 250c bored for external buttons
-
One connection to the switch is neg or ground (same thing). The pos switch connection is normally not ground unless the button is pressed. Thus if pressed, the pos becomes the same potential as ground. Now the chip sees the button is pressed. Virtually all digital switches work this way including keyboards.
-
Can someone explain to me how external buttons need to be wired? I have the image from evolv. Im just not sure on the positive and negative explanation.

Early Firmware and EScribe Suite Discussion Thread
James replied to David Campbell's topic in EScribe, Software and Firmware
I've uploaded a version, SP57. It's mostly a service pack for DNA 80 Color, fixing screen flicker issues and allowing graphical elements to be repositioned. -
EScribe Suite 2.0 SP57For US-based customers (Windows): https://downloads.evolvapor.com/SetupEScribe2_SP57_US_ServicePack.exe For international customers (Windows): https://downloads.evolvapor.com/SetupEScribe2_SP57_INT_ServicePack.exe Mac and Linux versions to come later. --- DNA 80 Color --- Fixed screen flicker. Made it possible to add a graphical startup logo. Made it possible to move all of the graphical controls.

Your last screen shot shows it throttling down from 34 watts to 29.38 watts. With the cell that you are using and firing at 34 watts that looks like there is still a problem. You seem to be on the right track to solving it. Is your adjustment screw on the battery cap at the end of it's adjustment? Meaning do you feel it may need to be holding to battery tighter?
-
" I noticed it kept climbing in charge when not using it to the point of gaining almost 10% charge within minutes, then taking a couple puffs, it quickly drops back to what it should be." Pretty normal behavior especially when charge is on low side. It is better to note actual standing voltage than to use the estimated percentage as it is just that (estimated). Here is a CSV for battery curve from my DNA250C, save yours first then give at a try if you want. It may be the same as yours or maybe different. Battery curve only changes percentages and battery bar, doesn't change how the mod works. DNA100C battery curve.csv

Thanks for the help so far, after cleaning the contacts and re-adjusting the battery cap, it stayed until 25% battery before dropping off. Not perfect, like how I used to get it to 10% before dropping but still, good enough that I'm happy with how it is now. Here's it with the battery at full charge and here it is at 25% when it started saying batt down. I noticed it kept climbing in charge when not using it to the point of gaining almost 10% charge within minutes, then taking a couple puffs, it quickly drops back to what it should be. Not overly concerning but just something odd. It was having a lot of difficulty reading the battery charge correctly compared to before

For what ever reason the board isn't receiving enough power from the cell (amps) do to a bad connection, could be cell fitment, bad solder joint, ect Use EScribe's Device Monitor to see your voltage drop while firing. Here is one of mine that has a poor battery to board connection. The voltage drops to 3.37 volts when fired at 45 watts. If it drops to soft cell cutoff of 2.75 volts it will throttle down the wattage. Check yours with Device Monitor.
-
Why 18650 if I'm using a 21700? I'll set it back to 2.75, but what would happen if it was lower? Oh also, and I'm using it single coil 0.20 ohm at 35w. Typically chain a few puffs then set it down for 5-10 min. The battery goes into low batt mode after an hour of usage.
-
The correct setting would be 18650 and cell soft cut off at 2.75 volts (default)
-
I just cleaned it as thoroughly as possible with cotton swabs and 99% iso alcohol on both ends that the battery touches. I adjusted the screw on the cap to fit as tight as possible. I was poking around the escribe software and the cell soft cutoff range was I think around 3.5V default and the type is set to 18650 and it won't let me click it to change to 21700. I just moved the cutoff to 2v, would that help at all?
