With your mod connected to EScribe and Device Monitor tab selected the firmware version is in the lower right side corner. The latest recommended version for 250C is 1.1 SP35 ( EScribe 2.0 SP17) and early release version is 1.1 SP38 (EScribe 2.0 SP19). https://forum.evolvapor.com/topic/66731-early-firmware-and-escribe-suite/ Most folks opt for the international version over the US version. EScribe will tell you when an update is available but early releases are not included.

Who did you make multiple ticket with? Evolv warranties the board for 1 year.

The 510 on the Drone is spring loaded and has a fairly stiff spring. This simple test will tell you if the 510 is electrically sound: Open EScribe with mod connected to computer with data cable with no atomizer and select Atomizer Analyzer at the bottom of the General page. Atomizer Analyzer should show "?" Next use a small screw driver inserted into the 510 to short the positive pin to the ground of the 510 (threads). If you get a reading of Ohms instead of a question mark then the 510 is connected to the board. If no change then the 510 is not properly connected to the board or the board it faulty.

Other than checking if the 510 positive pin is stuck at the bottom of the 510's body there is not much than can be done without disassembling it. Ask for help here: https://helpdesk.evolvapor.com/index.php?a=add&category=1 You will get a response, probably won't be till Monday as they don't operate on Saturdays or Sundays.

The reason that I deleted my post was because it was for the Vapecige box not the SXK Boxer. On the SXK I believe that the offset piece screws onto the 510 pin but am not sure.

What ever gauge Kanthal or Nichrome that you are using....use the same gauge non-resistor wire and it will vape pretty much the same at the same wattage.

I would recommend using NiFe 48/52 or Stainless Steel 316 for your builds, Kanthal or Nichrome would be a lot of mass at 0.25 ohms. O.25 ohms would be a good target, even slightly lower as the resistance increases with these wires as they heat up.

Your figure of 3.5 volts output (max) is right in the ballpark, you must use lower resistance to be able to achieve 30 watts/ 40 boost. https://www.the12volt.com/ohm/ohms-law-calculators.asp As far as battery sag/voltage drop be sure to use the most powerful 18350, Vapecell 9 amp or equivalent.

EScribe will help you figure it out as to what is happening. Your temp is rather low so it will be easy to hit. Check to see that your voltage drop when firing isn't dropping to the level of the Cell Soft Cut Off. Most likely you just achieving your temperature setting and the wattage is reducing as needed. In the snippet my DNA 75 dropped down to 2.71 volts for just a moment, the Cell Soft Cut Off here is 2.75 volts. If it would have stayed at 2.71 volts for any longer the wattage would have dropped.

Have you tried using the fire button that's on the board?

Method 1. Open EScribe, go to "Help tab" and select "Backups". The are dated, choose the one that you want. Connect mod and upload settings. Try with different cable if still having problems. Method 2. (see image) If no backup is listed open EScribe with mod NOT connected and choose your board, batteries, ect. Save (under File tab) to where you can find it (desktop?) You need to give it a name. With mod connected to EScribe go to "File tab" and select "Open"......choose the file that you saved and upload settings.

There are only two settings in Escribe that are going to effect the charge life of the cell. One is whether the cell charges to 4.1 volts or 4.2 volts and the other is the Cell Soft Cutoff. The curve will only make your battery gauge more accurate.

510 length just might be the problem. There is no standard for 510 so they can vary some. Is there anyway you can extend the pin on the atty?

I can only guess what it is for a 3 cell DNA250C. I would think 10 volts as the data sheet states but always it can never be more than battery voltage under load.

I just tried it with a DNA250C board with no change. As expected.

Yep, I tried it and it reset to zero, flashed it back and still zero.

Let us know how it does.

What I was concerned about is if the power wire's solder joints are connecting to the other side. If the voltage when firing is the same on both sides then they must be.

When firing via Device Monitor in EScribe do you get the same results?

Have you measured the voltage with a meter on the side with the wire?

It sounds like a poor connection between the board and coil. Using Atomizer Analyzer in EScribe can be most helpful. Self adjusting positive pins on attys can be problematic. The positive pin from the mod's 510 sometime gets stuck in the bottom of it's travel. Post screws need checked for tightness, ect. With Atomizer Analyzer you should be able to unscrew the atty more than just a quarter turn (approx) before reading becomes unstable,

There have been a few cases with that problem. I'm pretty sure the nipple position can be moved on the 510. There are some posts here about that here but I don't seem to be able to find them.
