I do all my testing at kano.is right now, but mostly that was because solo stopped working at my location. Course it was my own fault and that's long since resolved, I just haven't changed all the various scripts back over but I've been meaning to start pointing stuff at ckpool.
I've finally got time to work on the updated Terminus layout between 2Pac batches, so hopefully in a few weeks there's more of those can be pointed there as well.
Regarding voltage issues - no, I don't think the pot's busted. If the wiper's wiped out it should default to peak 1.6V, if the pot's disconnected somehow it'd jump to 2.0V. I can't really think of a condition where you'd see less than about 500mV across the string if the buck is working at all. Could be the buck controller somehow got nuked, or a different part busted off.

I believe every compac and every 2 pac should point to mmpool.org or ck's solo pool
to point them anywhere else is not a logical economic move. At mmpool or ck's solo pool the sticks have a chance to turn a profit since both pools give you a lot if you hit the block.
Thanks for the support of solo. Once I get enough hashrate on my new pool ckpool.org I'm hoping it will become a haven for small miners like this that actually do want to get a payout eventually of some sort, even if it's small. to point them anywhere else is not a logical economic move.

just had another issue while attempting to adjust voltage. i wanted to get 1.5 exactly so i turned it slightly, it read 1.6, so i turned down the pot again slightly, and now its only reading 0.17v and i cant get it to move from there. did i just break my POT?

arch for life. rebuilding vm. and i cranked it up from default 1/8 turn. dont know voltage; still dooze not work.
That VMWare USB Passthrough is a new one here I think. Also try controller type EHCI+UHCI if you haven't yet.
I experimented with hashing through VirtualBox and found it randomly unstable, but I get better luck not using xHCI/OHCI.
So update to my previous post.
I did change the ESXi 5.5 Virtual USB Control type from xHCI to EHCI+UHCI on the VM, at the same time i adjusted the voltage to 1.4v (yeah I know its high)
it started trying to init the device but gave me "failed usb_init" (this behavior was not seen before the controller change)
I then took the 2pac and hooked it up to my windows machine, installed the Zadig WinUSB drivers.
ran the following command in an elevated command prompt:
cgminer.exe -o stratum+tcp://sha256.eu.nicehash.com:3334/#xnsub -u 1XXXXXXXXXXXXXXXXXXXXXXXXXW --suggest-diff 32 --gekko-2pac-freq 100
[2017-05-30 11:57:50.849] USB init, open device failed, err -3, you don't have privilege to access - BSC device 1:3
[2017-05-30 11:57:50.852] See README file included for help
[2017-05-30 11:57:50.854] GekkoScience detect (1:3) failed to initialise (incorrect device?), resetting
[2017-05-30 11:57:50.857] failed usb_init
so both systems are behalving the same at this moment, yet im not able to mine. Not sure where to go next, I have reviewed troubleshooting info.
The "you don't have privilege" errors on windows and linux follows different paths for handling.
If you are continuing on windows, follow the conversation with anorganix beginning at the link below, up to the note on resolution, to see if it helps:

update on my 1 2pac and 3 compac's on a quality hub. With good fans.
Note that I run some gpus doing ZEC so the pc is already working much better then running a rasp pi.
note the 4 sticks point to mmpool.org
I believe every compac and every 2 pac should point to mmpool.org or ck's solo pool
to point them anywhere else is not a logical economic move. At mmpool or ck's solo pool the sticks have a chance to turn a profit since both pools give you a lot if you hit the block.
pictures coming soon
compacs at freq 225
2 pac at freq 275
0 hw for all 4 items
silver heatsink is the 2pac note the fan it sits on is turned off also it is fed with a y-cable and can draw 5 amps from the 2 usb 3.0 ports
2 scythe fans powered by a ham radio power supply I could run more then 30 fans with that power supply

I have one in each of the non-BC1.2 groups. So there should be plenty of power. I have a fairly big fan blowing across them (I can actually touch the radiator fins without discomfort), so I don't think heat is an issue. I have the speed set to 150 MHz (want to make sure they last a long time, and not trying to run them to the max).
The problem is that each of them (happens with all three of them) will only keep running about six hours or so. After that, I see the speed slow down, and then the line in cgminer changes to "ZOMBIE." If I unplug a zombie one, and plug it right back in, it starts up, and runs fine for another six hours or so.
...
Since these are fairly new, I am checking their progress often, and catching when this happens relatively quickly, but I would like to be able to "forget" about them, which won't be possible unless they stay running for a longer period of time. Any thoughts?
Halve the frequency (75 MHz) and see if they run longer than 6 hours.

@n_p, what OS and version is that you are building in?
Gentoo Linux (mostly "stable" - it doesn't really have a version
). May 28, 2017, 09:23:43 PM
Point the sticks to mmpool.org
If you hit the block you get all the rx fees. That can be 2 or 3 or 4 coins.
If someone else hits the Block you still get a share of the 12.5 size block.
I have 2 pac and 3 compacs pointed do 60gh

How many btc can we collect in 1 week using 2 GekkoScience 2Pac BM1384..
I have just one. I've been mining mostly on Slushpool for 22 days, I have a reward of 0.00017938 BTC or currently just over 39 cents. About 1 week before I got that I got a used Gridseed 80-chip G-Blade for Litecoin at $62 delivered. It runs on nominally 100 watts and in the past 24 hours has earned 0.010524304440 LTC or $0.2396384120988. Since I've had it online it's earned $8.08.
I think the best thing to do is set them up and forget about them, check once a day to make sure they're OK. It's just a hobby, unless you've got free electricity (solar, parents, running at work, dorm room, etc.) the 2Pac won't quite break even. There's a good calculator at https://www.cryptocompare.com/mining/calculator/btc?HashingPower=20&HashingUnit=GH%2Fs&PowerConsumption=7&CostPerkWh=0.12
Get practiced up and wait for Gekko's 16nm stuff. Or really bite the bullet and buy an Antminer S9. That can do like $3000/year profit, you just have to pay about $1500 for one. Everything seems to get obsolete in a couple years because the difficulty increasing makes them unprofitable to run. But solar panels are coming down to just over $1/watt, even at Home Depot.

How many btc can we collect in 1 week using 2 GekkoScience 2Pac BM1384..
I currently mine with 25 2pacs overclocked at 250mhz, which requires cooling and decent power. I also mine on slushpool, using my average as of today /25 then x7. I come up with approx .0001 btc per week as of today for one 2pac using said specs and pool. Of course all of that varies week by week.
May 28, 2017, 02:47:33 PM
If you're mining solo and the luckiest person ever, 12.5
If you're mining in a pool and have average luck, somewhere between zero and just-almost-zero.

Sidehack thank you for the personal response.
new to this and glad to see you are invested.
I will try and search this thread as indicated the answer would be.
thanks again guys.
just so you know my setup my platform is an old dell poweredge 2900 u5 with esxi 5.5 running, with a ubuntu 16.04 x64 VM running, is this a problem with powering the usb?

I'm gonna go out on a limb and suggest using the search function up there, because I'm also sure that question has been asked and answered twice, maybe three times already. Leastways if the problem is what I think it is.
