I tried to help him via pm conversation, hopefully you get it running soon.
Pangolinminer should be able to help you once they are at the office again.


I updated the opening post with the current 'How to order' information.

EDIT:
Update (December 24, 2017):
Pangolinminer is now taking orders through their web shop at their website www.pangolinminer.com
They should have few different shipping time batches for sale during the Christmas time.
The counter at the web shop page indicates that this would happen in December 26, 2017.

A quick update for you.  I eventually got technical assistance from the Whatsminer guys, they connected via Teamviewer.  They changed my DHCP address settings on the M3 to static address and disabled the NTP time server settings in the device config.  Now it works.  Odd, but happy nonetheless.  Next question I have, with cooling requirements (because this thing gets SO hot, i am wondering if it is even worth having.  At roughly $6 per day for electricity, and the device only makes about $15 per day (without cooling) I don't think this device is profitable.  If I factor in cooling, that takes a further chunk out of that $15 per day value.  Also, I was connected to Slushpool and after several hours the Slushpool dashboard eventually came down from 31 years to threshold for payout to 6 months.  That was with payout settings @ 0.1 BTC.  So I changed it from 0.1 to 0.01 BTC for payout.  After a few more hours it eventually changed to 2 weeks and 1 day to reach payout.

So my thinking is, if this device takes 2 weeks to payout a mere $130, with $6 a day electricity ($90) that means on a 2100w device profit is $40.  That is not worth it at all.  I've been watching YouTube videos where guys are making $50/day using an Antminer S9 with 13TH/s which is hardly that much more than the M3 so I don't understand how @ 12TH/s this M3 is not really profitable.  You would need several of these devices, but one definitely is not profitable by my calculations.  To contrast this, I have 5 GPU's (not even a full rig, I have 3 GPU not attached to that rig yet) that does over $20 per day some days with a smaller and 80+ Gold rated PSU and I've watched my electricity consumption and it's noticeably lower than the M3 and the entire rig has an average temperature of 60 degrees celcius.  Granted it is mining a different coin but the point I am trying to make is that unless you have a mining farm and you're selling hash power, Bitcoin mining is no longer profitable.  The reason these mining farms make so much cash is that with every contract they make their money back almost instantly, so their sunken cost are returned far ahead of schedule in comparison to a solo miner who needs to earn back their sunken costs.

What are your thoughts?
