Even with the latest VB and tools? I have El Capitan on one of my Mac's but have not had a chance to test escribe on it as it is not typically one I goof off with. After putting it on that one I realized that it was not ready for prime time so to speak and have not upgraded my main systems.

The setting described will not impact charge or battery life, but it will make the meter correct. The only practical way to get more vape time out of a battery is to vape at lower wattages and make certain it is charged fully (using the "max puffs" setting).

It is time consuming and requires accurate measuring equipment. You need a way to measure ohms to the thousandth and a very accurate temperature measuring system. This post and the thread it is in will be a start: /topic/68195-topic/?do=findComment&comment=913245 Alternatively you can write to the steamengine creator and talk about what you see as wrong with the profiles created.

As mentioned, do a manual update and let us know how it worked. Assuming you mean the device won't turn on and not the computer.

Perhaps a hard reset by pulling the battery connection? Any clues by visually looking at the USB connection? Bent etc?

I do like this mod. What is the 510 like? Wave spring?

A small O ring under the post will allow more torque and better internal contact while still letting the tip stick out just enough for the 510. I have 8 GTs and three of them are crap for TC vaping for that same reason. A .25 build slips to .35.

Love it...and the fact that it can work in a virtual machine.

I trust James....AND will add that even adding my device serial to the virtual machine I still had issues (so it could see the failsafe device ID). I ended up flashing new firmware via a windows system. If it happens again I will test the virtual machine recovery more. Your success means that we may not need a windows box at all.

I would start with the vendor or manufacture and ask for a replacement. If they give you the bum deal, they you can take the existing pack and measure it and source something on the hobbyking site (they have a great tool and their Trunigy products have proved inexpensive and good performers). I have a few of these and if they fit, are great: http://www.hobbyking.com/hobbyking/store/__11903__Turnigy_nano_tech_1300mah_3S_25_50C_Lipo_Pack.html

That is exactly my issue. A windows system fixed it. I loaded escribe on the windows box, connected the device and rebooted the launched escribe. It was able to do the flash and I have since flashed it with VirtualBox since...AND...they have increased the USB timeout to prevent EEPROM bricking. Good luck.

Cell 3 may be impossible to recover and the pack is shot. I see no reason why you can't leave it for a few more hours though. I don't know the standby power requirements of the DNA200, but it should not have driven them down to 0. I suspect a bad pack or cell at this point (that took the others down to 0).

My opinion of looking at your graph is that you have some moderate voltage sag while vaping. Also your capacity setting is a bit high for the real life of that pack. I would: Let it charge fullyChange capacity to 13 (just as a test)Vape again with the device monitor on and just look at the cell voltages to see how low they go.The area to look at is the cell voltages that you can see dip while you vape. Thus far it looks like a basic poor quality Lipo pack. Just for comparison, here is my pack taking a similar hit (the sag is there, but not forming a big dip):

I bricked one once using a virtual machine, but was able to get it back up by using a PC. The Mac thread has some bits of the tail. My fix was to connect it to a windows computer, boot with the bricked device connected then launch escribe, which allowed a firmware update manually. That said, my issue was that I had bricked it with a failed update (virtual machine disconnected from the USB during the write). Your issue is described as not related to the update, but if it is, give it a shot.

Take something the size of an old fashioned broom handle. Make five well spaced wraps with kanthal and give yourself some long leads to get it away from the mod. Remove from the broom handle or whatever you used. You are basically making a giant free air coil. That should work just fine and you can adjust the wattage of the test down if you are worried.

What is the capacity set at now and can you take a shot of you vaping normally to show the voltage sag? Put a check mark in each cell box to track them.

Looks great. My only suggestion is for a commercial setup, why not just skip the atomizer and put a female plug directly to a DNA200 OUT and GRND for a dedicated test station?

I had to power on the windows computer with the "dead" DNA200 plugged in (with a known good USB cable).

I have seen a lot of battery related posts here and on other forums. So I will share a bit of frustration with Lipo pack manufactures. There is still a lot of variation in cells, and multi cell packs just increase the total failure rate. On top of high failure rates, we now have packs that are advertised as having a given wH capacity that in fact have nowhere near that. A user putting such a pack in a mod and then using that advertised value will get wildly unpredictable battery bar action. We have brand new mods with packs that advertise 1.4 wH, but are shipped from the manufacture with the default settings in Escribe, and still drop from 80% capacity to 50% capacity in one vape due to sag and a weak cell or pack. In some ways we the consumer are perpetuating this in that we want the mod for the best price, so there is pressure to put in a cheap pack. The end result is a mod with a pack that has a weak cell, has nowhere near the capacity advertised or can't sustain the C rating required for vaping. Personally, if I were to buy a commercial mod (and I doubt I will) I would want to know the details of the pack, how to order a replacement if needed and that the pack in general has been tested for the wH advertised and the amp draw (C rating) required.

In Escribe, click "Device Monitor" and you can see the charge levels of each cell as well as lots of other data. It is a great tool and you can vape while watching to see if your pack sags badly. I have seen a good number of folks with that mod complaining about limited capacity and sag. Some have complained to the manufacture and gotten replacement packs.

I am using SSV wire now and getting a good vape, so some random things to check: Is the CSV in the profile you have selected? Is the atomizer good at TC or is there a variable resistance issue with it (when it gets hot is it changing the resistance to the point where the DNA200 "thinks" it has reached temp?) Is the 510 well grounded so that variations in the ground don't trick the DNA200 board into thinking your coil is hotter than it really is?

What atomizer? How is it setup? If you have limited juice flow, then you can be hitting TC due to poor wicking.

Thanks...got 'em. I missed the display brightness issue...wow.

It is as you suspect, simply a configurable figure for the new same/new base assumption. Within that range it will assume it is the same coil and not prompt you. There must therefore be an upper range that it automatically assumes is a new coil, but that can not be set.

Common Troubleshooting Steps (feel free to correct/expand/enhance this) Screen is blank, but device functions: Verify that it is not in stealth mode: Lock the device and hold power and down until “Normal Mode” is displayed.Verify that screen is not pinched by the fire button, if so, return to manufacture for service.In Escribe - Help -About EScribe click the logo 7 times then open Device Monitor and look at the screen disconnects. If that is > 0 it is a screen connection issue, could be the cable has come out of the socket or the cable is damaged. Device powers on only when connected to USB power: Fuse is blown: Visually inspect fuse or test with ohmmeter. Return for repair if blown.Battery is dead or low or a single cell is dead or low: View cell charge levels in Escribe to verify that the device sees a three cell pack and that each cell is charged above 2.00 voltsBattery Meter is inaccurate/Battery % Jumps Down: Watt-Hour setting in Escribe is incorrect. Calculate Watt Hours using battery analyzer and enough coil wire to form several large loops to dissipate the heat. The pack you are using likely has less watt-hours than estimated.Weak Battery displayed when battery has sufficient charge: Launch Device Monitor and view each cell’s charge level for sagging during vape. Verify watt-hour setting for your Lithium Polymer pack is set correctly.Battery won’t charge to 100%: Using the watt hour calculator to guess at a figure will at times result in a number that is actually in excess of the real life figure for the pack. Run battery analyzer to get a correct figure or simply reduce the rating. Warranty Service Error Message: Warranty error means that the logic voltage regulator is running out of spec. That could be due to a soft short circuit somewhere in the logic circuitry, a total battery voltage under 4v, or similar. Verify cell voltages and replace battery if needed or send mod in for service if the battery is to spec. EEPROM Programing/Read Failed: Escribe attempted to write/read to/from the device but failed. Typically related to a poor USB cable or a computer with considerable lag, causing slow USB response. Use a known good cable, eliminate running processes and manually try a firmware update via Tools and “Update Firmware”. Device won’t connect to Escribe: Inferior USB cable – half of the diagnosed connection issues can be traced back to a poor quality cable or one lacking the wires for data (a cable sold for cellular device charging).Device Autofires: Generally caused by a short from the “OUT” connection to the atomizer and board ground (due to poor soldering or erosion of board coating).Ohms showing 0.00 with new atomizer: Ohms will display 0.00 until the fire button is depressed with a new atomizer.Resistance is variable and results in poor vape: The ground path is crucial. Some mods (like the Hana) did not install a ground path and relied on the 510 connection to the case which could be unreliable. Install a dedicated ground connection to the board.Many atomizers are poorly suited to vaping in TC mode. They have springs or loosely threaded center pins that can cause big swings in resistance. You can fix some of this by unscrewing the pin, cleaning it and then re-installing and potentially leaving more exposed so there is more pressure on the 510. You can also increase the pressure of the 510 spring. Temperature Control Not Working: See the variable resistance issue. Once Cell of the Three Cell Pack fails to Charge: There is a rare board assembly error where one of the four resistors near the USB plug will be omitted or poorly attached. This can be seen with a visual inspection. If one of them is missing or not installed correctly, RMA the board. If the board is functioning and the onboard resistors look intact, then one cell of the pack may be bad. The mod will not charge and cell voltages read low: The device will not charge cells below 2 volts. To try and recover an over drained pack, in Escribe select Device Monitor, Diagnostics, Advanced and “Perform USB Recovery Charging”. You may need to do this multiple times.The custom fields I chose to display while charging do not display: Check the screen brightness is greater than 0% for charging in Escribe, they only display when in idle about 30 seconds after connecting the cable.USB port gets hot while charging: Check for blown fuse by looking at battery voltage in Escribe or general mod operation.Device will not fully charge: Verify you have the right battery type selected. If using a Lipo pack, but lipo4 is selected it will only charge partially.USB Recovery Charge Fails: USB recovery charge only works for cells that are above 1 voltUSB recovery charge will not work if the mod internal temperature is over 130FUSB recovery charge may need to be run multiple timesThe pack may not be recoverableWhat initial setup items are essential?: The main things it to do: connect to Escribe update the firmware, check the battery Wh are correct, increase the max Kanthal watts if required, choose between "max puffs" and "max recharges" battery options, set the charge screen brightness above 0% and put USB current in one of the custom fields so you can see if you have used a 1 A USB supply to charge.Why is my VT200 battery meter dropping so fast?: Some of the packs shipped with this mod have less than the advertised 14.43 watt hours. One users tested theirs to be 10.7 watt hours. Putting 11 in the pack rating will result in a more accurate batter meter. It is also suggested you test your pack with the battery analyzer tool.I can't get over 100w: There is a non-TC limit of 100w as the default in Escribe. You can set it higher if needed.I am having issues with Stainless Steel: Stainless steel is an alloy and has issues being used as a TC control wire. At a minimum start with a good TC atomizer and a known mod resistance. Read this great write up by James (Evolve): /topic/67959-topic/?do=findComment&comment=911599Escribe won't update: Open your web browser and verify you can go to https://my.evolvapor.com without any certifcate errors.Device will not stay in temperature mode: Jumping out of TC mode is typically related to the use of low TCR wire with an inaccurately entered mod resistance value. If you have a low resistance build, say .08, and a very low TCR wire like stainless and have a mod resistance of .008, but it is not entered, the combined resistance of your wire and your mod, .088, coupled with the low TCR value will cause the DNA200 chip to fail to see enough of a percentage change in the wire to justify TC mode. If you are using low TCR wires then you must put in a VERY accurate mod resistance and TRY to build higher resistance coils. Higher coil resistances limit the max power with two cells or Max resistance is lower for two battery cell operation The DNA 200 is a step down converter designed to run from 3 Li cells is series and is limited to a max output voltage of 9 V. Evolv released firmware that allowed it to operate from 2 series cells at reduced power (133 W). The max output voltage has also changed to 6 V (2 cells in series). This changes the resistance range usable to between 0.0532 ohm and 0.27 ohm for 133 W (max power). DNA 200 with firmware V1.2SP3 the battery bar shows empty after updating firmware and sometimes after uploading settings or disconnecting the battery. This is a known issue Evolv are working on, it will not damage the mod or battery and normally recovers after the mod goes into sleep mode, you perform a soft or hard mod reboot or upload settings.
