1  Bitcoin / Mining support / Re: Canaan Avalon 1246 Repair Suggestions Needed - 1 Hashboard not working on: June 11, 2021, 02:55:25 AM
I was to the point of sending a hash board to blokforge, sent them all they wanted. right before they sent me approval, I had moved the machine and when I plugged it in, Bam! everything is fine! kinda crazy, makes me think firmware upgrade they offer may be in order. I'm not interested in doing that yet, don't wanna screw it up and have a dead unit. As far as disassembly, super easy. They sent my a Avalon video link. I had already removed hash unit previously to look for hardware issues. The unit was quite dusty in the short time used maybe 40 days or so. I removed and cleaned everything this eve. In the future I plan to just remove the fans and blow the dust out from the exhaust side. how often do farms clean their rigs? looks like it will be monthly for me. mfr didn't skimp on the grey thermo paste. its like working with antisieze, gets everywhere.
NOTICE: you do not have to remove but two screws and the connector to remove a board. the video is for complete breakdown of machine and they remove control board and everything. Careful removing fans on inlet side, the temp sensor is there and kinda fragile. also fans are best kept on fan plate, not necessary to remove each one. Top panel slides off.

luckily, I did not have to unplug bad HU or board to continue to mine. Seller let me know there is firmware to allow to mine on good boards. since I was able to get machine to mine, I would not commit to trying to update firmware. My version is below. I did out of frustration do a factory reset and that was a nightmare for me. I had a hard time getting my pool back into system but it ended up being a stupid mistake on my part. looking into the manual thats on mfr site, I can say, I would not want to update firmware, afraid to make a mistake and ruin machine. good luck! I have since given seller info and waiting for them to ship me a HU.

mfr said parts to seller next week. I love the miner, wish they sent spare parts with batch's. runs a sweet 56-66t on 2hu. normal mode.

i cannot say it was anyones fault that the chip shortage or issue, my March batch came out 85th instead of 90, and the deal was accept or cancel. that was brutal ontop of premium cost.

I wont or should take back that they passed the buck. I'm a newb and maybe need to understand how things work. looks like the customer has to talk to mfr avalon to get log read and then instruct blokforge to support. I was on here in panic since I hadn't heard back from avalon at the time. I went all in on the machine and when it went down my anxiety took over.  I have since realized that there were truck loads in many batches sent out and there are just a few of us talkin bout issues and they are communicating with me and look to support. agree with the comment that I could still be waiting for a machine...

HagssFin,
I greatly appreciated your help. I was educated by you on the log and had the forethought or afterthought to send it as a reply to my initial email. I wont throw names around as I am at their mercy, lol. The fella at Avalon replied and agreed that I need a hash board. And to work with blokforge supplier to fullfill this need. so I am happy to report that they are supporting the customer. I would think that if the market wasn't as strong at the time that you would have gotten one to review? maybe not as they have Voskcon review video already on their page, next to the manual in support page. I like blokforge but was a bit dissapointed that during my chat to resolve issue I wasnt assured that it will be taken care of. To him it was standard reply, but to me the machine I spent a handfull of bitcoin on was huge to me.  When it broke my lil world fell apart, kinda.

HagssFin,
  I've referred to table 4 and I would assume from your reply I am at the mercy of Canaan. when I opened unit, I noticed the center board did not have red light on, so I assumed it was board #2. The temp that showed zero celcius is labeled H2. Of H0/H1/H2. Your review mentioned 3rd board? so I am assuming board with light out in the middle is bad. The temps # labels have me confused as to physically which one is bad? should I go by the light out or persue understanding the configuration of HU labels? in another post a fella mentioned Canaan would send blokforge (US seller) the replacement for him to install.
Thank you! your guides are most impressive. I have alot to learn. I thought it would be easy.

HagssFin,
I can copy the log but would need guidance on Code stuff...
Is new firmware utilized for batch management or will it fix stuff? like one board not hashing.
haha, honestly I did try to google how to #function, but thanks for the push in the right direction.
10  Bitcoin / Mining speculation / Re: canaan avalon 1246 on: May 15, 2021, 06:57:30 AM
I wish I ordered bitmain... Waiting for an email from Canaan support after blokforge passed the buck. Ive since learned that this is standard practice and no slam meant for them. one of three hash boards are not working. Ive only seen a few others posting of issues with 1246 but I can say 100% of the one I ordered is only hashing at 56T.
11  Bitcoin / Mining support / Re: Canaan Avalon 1246 Repair Suggestions Needed - 1 Hashboard not working on: May 15, 2021, 05:05:01 AM
I lost a board, red hash2 on root menu and the H2 temp reads 32degrees f. I see the center board light is out so I removed it but chickened out on removing heat sink screws, don't know if there is anything I could do if I did find something....emailed and wtg response from Canaan.
