I lowered it to 540 freq and around .65 core voltage, went well for 2 days. Then the same thing resurfaced.
Multiple errors, but now the hashrate goes even lower ex. 1.5.

It might have been something with the assembly of the ML by the distributor as the large heatsink with fan came loose (heat?) and I had the put it back.
It was already average assembled from start (fan and heatsink were pretty much off target by 0.5cm Wink

)

I can't even let it run for 30 minutes now on low freq and voltage or the glue/paste starts to go soft and as I ran the thing horizontal the fan and heatsink would just fall down.

I'm not much of a hardware guy so I'm trying to explain the things as I see them

Thank you!

I don'n know, sounds strange, glue/paste should go soft and starts to peel off at temps when your ML would be dead, at least twice, and it looks like it is alive and hashing with some solvable problems. Maybe you should send it back for repair, it doesn't sounds like something unrepairable but 0.5 cm off target for something 2,5 cm long was red flag from start... Did my best, good luck!

Hello,

I've been running a ML2 for about 2 days, pretty much at stock settings (upped freq to 620) on a macbook pro usb3 port.
It has been running stable for that time, but suddenly the hashrate dropped to 2.1 - 2.5 MH, it used to be stable at 3 - 3.2 MH.

Am I missing something right here? My setup didn't change (no other devices attached).

For stable 3 MH you will need more than 500 mA. Can macbook pro usb port suplly current more than that?

I have no idea, I can only tell what I saw these last 2 days.

This is what system info says

Current Available (mA):   500
Current Required (mA):   100
Extra Operating Current (mA):   0

Apple docs:

Apple computers equipped with USB 3 provide up to 900 mA (milliamps) at 5 V (Volts) to most Apple USB peripherals as well as all third-party USB peripherals that comply with USB specifications.
https://support.apple.com/en-us/HT204377

According to docs, it can provide from 500 mA up to 1100 mA, depends how much attached device is in some way compatible with oem apple devices. Try to lower clock speed @540... Dropping hasrate is usually all about lack of juice from usb port...

EDIT: 620 is not available clock speed listed on first page.

oh wow..
Must be a typo, I'll see what fixing this does.

Thank you.

It's on 625 now, but it seems it doesn't matter much. I used to get 3.2MH on 600 and stock settings, but hey better than nothing Wink

I'm mainly doing this to support and because I'm interested in it, not to get rich.

It is getting worse and worse from now on. It has drops to 1.5MH.
Frequent unknown responses, restarts,..

I have to lower my freq everyday, while it was stable the first 3 days, something definitely is wrong.

Screenshot: https://www.dropbox.com/s/mce5t24ee1w4yu1/Screenshot%202018-02-21%2008.35.11.png

I think you should decrease Vcore to 0.65V. Read page #34 of this thread up to post #669.

Yea to get under 1A and stable operation off a standard computer USB port your going to need to lower the voltage and run under 600 MHz.

I lowered it to 540 freq and around .65 core voltage, went well for 2 days. Then the same thing resurfaced.
Multiple errors, but now the hashrate goes even lower ex. 1.5.

i dont get this hub to work... the PSU is 30A on the 5V side

i get tons on "moonlander has stopped hashing" and "unknown rsponse from moonlander" msg

they work (if) very slow also on this hub and get HOT

http://prntscr.com/iitlw5

any recommendations to get 12 Moonlanders loadet?

greets
mike

Was Having a similar problem trying to run 15 on the big eyeboot hub. I left the clock at 600 and raised the minimum difficulty to 2048. While I only get 3.4 Mh, they run much more stable. I also added some options to the command line that really helped seemed to help. I also put a some small usb fans in the empty slots on the hub to help move the air.

bfgminer.exe --scrypt -o stratum+tcp://us.litecoinpool.org:3333 -u worker.1 -p 1,d=2048 -S MLD:all --set MLD:clock=600,baud=23040,chips=1,modules=2,usefifo=0,hotplug=17,thread-concurrency=50000,lookup-gap=0,gpu-threads=1

Are you mining BBK? If so what pool are you using if you don't mind me asking?

I was on minpool for a couple days, but became the only one. Went over to hashfaster both work fine, but the risk of an orphan block on minpool made me switch.

GUYS I CAN'T GET IT TO WORK ON MY PI Cry

Had an issue as well. I used the instructions here:
https://steemit.com/raspberry/@qctechno/howto-install-futurebit-moonlander-2-usb-scrypt-miner-with-raspberrypi-3

It doesn't have the updated driver with the restart but it works. Also make sure you your hub is at least 2A per port. Run sudo lsusb on you pi before starting the install to make sure it sees them.

So I decided to add some command line options to my start file that significantly increased the stability, slightly increased the hash rate, and significantly decreased the HW on my old Gridseed Blades, with a few changes. Lo and behold, the same effect was had on my wonderful Moonlander 2's. I am running 17 of them at the moment on some pretty good hubs. I saw a stability increase of a day or so, hash rate increase of 5% and 50% reduction in HW!!!. Not sure what all of the settings do but hey it really seems to make a difference. I also always launch Bfgminer with full Admin privileges on Windows, the same effect was had on the Pi 3.

C:\moonlander\bfgminer-5.4.2-futurebit2-win64\bfgminer.exe --scrypt -o stratum+tcp://us.litecoinpool.org:3333 -u worker.1 -p 1,d=4096 -S MLD:all --set MLD:clock=600,baud=23040,chips=1,modules=2,usefifo=0,hotplug=17,thread-concurrency=50000,lookup-gap=0,gpu-threads=1

Cheers and Happy mining

Ok thanks so much for the help! Last thing what version of linux you running im using noobs thhat might be the problem

NP.
I'm on NOOBs as well so i don't think this is the cause.

If you emailed me your folder would work?

I don't think so, apparently there's something wrong or mising in your system. If the above mentioned commands aslo not working then I have no idea how to fix it. Sorry.

Hi I realised I made 1 typo I fixed that but now when I go to ./start_moonlander2.sh it says (error while loading shared libraries)

Well, this is above my knowledge.
Only idea I have is whether you performed system update and upgrade? (sudo apt-get update and sudo apt-get upgrade)

If still not working then you'd better ask Astrali for help.

EDIT: see this

2) When I try and execute the script on a Pi3 it says:

Code:

./bfgminer: error while loading shared libraries: libjansson.so.4: cannot open shared object file: No such file or directory

EDIT: I fixed this with running the following:

Code:

sudo apt-get install autoconf autogen libtool uthash-dev libjansson-dev libcurl4-openssl-dev libusb-dev libncurses-dev git-core

Many thanks It helped loads but when I get to start it so. (./start_moonlander2.sh) it says no such file found or directory.

Also on the very first step it says Unable to locate package libcur14-openssl-dev

Anyone know why or how to fix

Thanks again.

I tried the first command and have no issues:

Hi, can someone please tell me step by step how to set this up on NOOBS (Linux) on raspberry pi 3B. i AM USING A POWERED usb hub. My problem is the (driver download) seems just to contain BFGminer not the driver.

Many thanks for the help!

I followed guide made by Astrali and had no issues:

Any chance someone can write up a step-by-step guide for getting these working on a Raspberry Pi 3B? I'm a Linux novice and most of what I see assumes a certain level of know how. I was hoping to set it up wirelessly on Minera, but at this point I'm so confused I'll take what I can get... Thanks in advance!

so you need the a foolproof copy n paste "just get it to work" description?

i'll write a short version for you that is most probably not perfect - but will most probably work.

That is the bfgminer software ... you need to set up a driver first as well.

For Linux, you don't need to install a separate driver, right? It's supposed to be included in the kernel.

Yeah the driver is already included in the kernel

After much thread searching and lurking I found that the Rpi USB is crap, and that it hates anything above USB2 (even hates some USB2) and a fix is to force the Rpi to only use USB1 by adding “dwc_otg.speed=1” to “cmdline.txt”.

After adding this (running 4 MLD on a orico 10 port USB3 hub with Rpi3) everything seems to be working fine Cheesy

I can now go 700+ and so far seems stable, will post back later once it’s had a good run to confirm

Hopefully this will help others having the same problem on a pi

This thread pointed me in the right direction:
https://bitcointalksearch.org/topic/do-you-hate-the-pis-usb-ports-like-i-do-here-is-a-fix-for-us-miners-843788

This seems to have solved it, it’s been more than 16 hours now and it’s still up and running, much more stable and no drop in hash rate (other than expected minor fluctuations) Cheesy
