After receiving a better powered hub today i've started tuning the 3 moonlanders which i currently have. They are all running stable at 832 clock speed. I've copied the setting for core voltage and memory so all 3 are set in the same way. HW error rates are at 0.38, 0.06 and 0.94% so thats nice and they are hashing along at ~4.70mh/s each. Quite happy with that figure. One 'issue' though, 2 of the MLD's reach a temperature of about 51-54 degrees celsius. The third goes up to 72-75 degrees celsius. I've already ordered some external fans so that should bring it down a couple of degrees but other than that, any suggestion as to why 1 of them is running so hot? Thanks for any ideas  Check the back heatsink, it could have not been applied correctly. Just put some pressure on it and make sure its stuck on there well. |

HI I hope you are well.
I was hoping for some help/ info. I am new at this.
I purchased 2 moonlanders 2 Iand have managed to get my two Moonlanders going using your instructions (they are running on a Pi 3 externally powered hub) and i can monitor them.
So far I have tried to mine nyancoin from multiple pools and also XVG.
When I first execute the BFGMiner i get them mining with thered led flashing, however, within a minute or two the difficulty on the block goes up and my moonlanders seem to stop mining, green led ok, no red led I have tried the lower difficulty ports on the sites and I have tried changing the difficulty in the start shell script too.
Do you have any ideas?? Are they still mining or have they been frozen out. Is there a work around.
any info would be great
these are cool little machines
thanks
No red LED flashing usually means they have stopped mining, but you will also get a notification in bfgminer saying they have stopped mining and it should restart them. |

Is there a way to control the fan speed? I bought a replacement fan with the same specs 5v 0.2a but is rated at a higher speed so therefore much louder than the original fan. Can I control the fan speed through the software or do I need to control it through hardware? Thanks.
Im still wondering this myself. Does anybody know? Stock Fans are dumb and are regulated via voltage. @ 5v they reach about 10k RPM. If your replacement fan has a third yellow wire, you can control it via PWM signal, but that would require and external PWM fan controller. |

Hey can one of you guys pull a board from one of these and take some high res pics of the front/backside. Can’t find any pcb pics for the A4+ just the A4.
Sorry to say but your going to be dissapointed. the boards look pretty much identical except a slightly diffrent chip number under the heatsinks. Highly doubt that...A4 had 80 chips on 4 boards, A4+ is 288 chips on 4 boards. |

A little confused as to why this miner difficulty got worse? One would think that more people mining, it would become easier. .. or better yet, a 'fixed' mining difficulty rate.
If the price keeps declining, the difficulty will adjust, boosting profitability. If the price rebounds and begins to rise, the difficulty will continue to rise and catch up, but profitability should still rise. The only ones losing out on this are the ones selling their machines and/or selling their coins. The winners are the ones that hodl. Lol you wish buddy. Thats not how it works...Currently nearly 100% of the miners on the network are all L3+/A4/L21, which still have a very large margin of profit before power. The difficulty will only continue to go up especially this month with all the L3s being shipped (10s of thousands), regardless of what the price does (unless there is a massive dump, but even still people wont start turning off this generation of miners until $50 LTC or so). |

I got the moonlander running on a pi but the pool hasrate is showing 30-40H/s, not a typo that is hash per second. These are p2p pools and I tried with 2 different pools and two different moonlanders. Locally it is hashing at around 3.3MH/s 0.5% HW errors and the terminal window shows "something" accepted every 10 seconds or so. If I plug in my old gridseed in the same set up it shows on the pools the correct 350kH/s. USB voltage if fine. Another issue is if I try with a MAC (El Capitan) all I get is: Last login: Mon Mar 5 17:12:45 on ttys001

...completed./code] The MAC was just to test if I had the same low hash issues as with the pi. I need it to work with the pi. Also I wish this moonlander had a proper +5V connection(soldering tab) so I could connect a powerful PSU directly to them rather than bottlenecking the power though a hub. The cost for such hubs that also transfer data is ridiculous. Does anybody know a hack to separate the logic 5V from the moonlander's power or would it work if I just lift up the 5V tab from the USB socket on the moonlander and solder my 5V directly onto PCB? Maybe a ceramic capacitor over the tab and the 5V for AC reference. Sounds like a pool formatting issue. If its showing 3-4 MH locally and 30-40 H/s on the pool I would assume they got their display number off by some factor. Mac issue is explain in the first post of this thread. Nothing below 10.12 is supported. |

Can someone please help me figure out how to send my miners to 1 or more coins at a time? Currently I can only mine 1 coin at a time. I was hoping there was a way I can set 1 or 2 of my sticks mining different coins at the same time? Is this possible?
This has been covered multiple times here. You need to create two separate bat files specifying which sticks and which pool you want run with each bat file, and run two or more instances of bfgminer at the same time. there are 63 pages on this thread .. Most of us are newbs. . at least a link please? or something I can copy & paste? Find the COM ports each stick is connected too. Change the "-S ALL" in bat file to "-S MLD:\\.\COMx -S MLD:\\.\COMx" with x being the com port numbers. If your using linux the format is MLD:/dev/ttyUSBx |

How long will take to make ROI at 3.5-4 Mh/s - 1 stick?
Off topic and irrelevant.  Yes maybe is off-topic and irrelevant. Anyway is there a lifetime of sticks if i run them at default settings and in a cool space ? Why i ask? Because i want to buy more MLD2. And will be in future a MLD 3 created with more speed ? Lifetime on default settings with proper cooling should be on the order of years. |

I was running Moonlander 2 for a couple of weeks, from internal USB of the laptop and had stable 4.7MHz/s speed at 832 freq.
Now, I got a good quality 2A USB hub. I put the core voltage slightly up and frequency 852. For a couple of hours it gave me speed of 4.9MHz/s and then stopped. I put the voltage back to previous position but now, no matter what frequency I put I get a speed of 3.1-2.4 MHz. Anybody knows how to check if I damaged the device? E.g. is there a way to check number of alive cores?
Thanks!
Put "-D 2>log.txt" at the end of the bat command. Start it up and it will spit out the log.txt file in same directory. In there you will see startup sequence and it checks for number of active cores. Should say 64. Thank you for reply! It finds 63 cores. So one dead core. But it used to give me stable 4.7 MH and now I can't go higher than 3.5 MH. Could there be another reason? Sounds power related, also try turning up your memory voltage to around .9v, this sometimes helps with stability. |
