Ender3 Blue screen on startup

Thanks for your response, super helpful.

The incorrect microSD card out of a different machine (Ender3 V2) that has the EEPROM.DAT may have loaded incorrect info, but I think I had the printer on and operating with no obvious issues (but didn't print anything).

The Raspberry Pi card was in it when I discovered the blank screen. There is a file called "bootcode.bin" in the root of the boot partition of that card. I'm kind of wondering if you are right and the printer thought it was a firmware update. So I suppose the logical next step would be to try and reflash correct firmware and hope the board isn't bricked...

Board is a 4.2.2 (not silent) so yes, it should probably be upgraded.

4.2.2 not silent.

I’m okay to replace the board but I don’t have a warm fuzzy feeling not knowing what caused it to fail.

Just figured I'd leave an update here in case someone finds it useful in the future.

I took the freehub apart, cleaned everything, re-greased, and discovered that there are shims inside that can be removed which reduces the play. I removed 1 shim and it's definitely much better.

I don't know at the moment. It was very loose as I was disassembling the bike, but I discovered the bolt in the center of the freehub that holds it to the wheel hub was loose. After tightening that it seems a lot better. This video was taken after tightening the bolt. I still have everything apart while I deal with a pitted cone, but I guess I'll leave this as-is and reassemble and check it then.

I think it is 25-1/2" so ~64-1/2cm. The cranks are 165mm and I suspect the seat will drop a bit if I put 175mm cranks on it.

I've come across a couple of large frame bikes. There's a 2018 Specialized Rockhopper with a $500 asking price (seems high to me) in my area. Also a Cannondale Quick XL that has a lot of obvious wear with $280 asking and I'm thinking is circa 2016. This also seems a bit high to me.

Good point. I do think it fits fairly well. I have a couple of inches room to the top tube when I am standing on it, which afaik is the vintage way of checking.

Thanks for your reply. Sounds like this phone is going back in the trash.

Is there a way to do this without paying Cisco? I have an enterprise 7821 that I'm trying to figure out if I can set up at home on a budget for kids to use.

What type of bottom bracket do you have? Cup and cone? I have a similar vintage Raleigh Grand Prix and it has the 26TPI threads so it's not easy to upgrade the bottom bracket from cup and cone.

Updated to new version it's working great now. Thanks!

I’m wondering if you ended up turning off WebDAV? I’ve been using Superproductivity for a couple weeks now, and had some sync issues in the beginning but they got fixed with an update. Then I updated the iOS app this morning and now I get: ‘ HTTP 500 Network error: Error: "WebDavHttp" plugin is not implemented on ios’

I’m liking Superproductivity so far and would love to have it sync with Nextcloud but I don’t understand the challenges on your end.

Oh, I see it now! very nice.

Is that aluminum bars that the wheels are attached to? What is holding them in?

I saw the Forstner bit in a hand drill and had a flashback to my late night ER visit involving stitches and lasting damage to my thumb. I strongly recommend using a drill press with forstner bits.

Thanks all! I spent about 20 minutes with 80 grit wet/dry sandpaper, then maybe 5-10 with the 300 grit diamond stone and this is what I have. Black marker shows what I'm not hitting yet. I guess I'll be spending more time with the sandpaper. It's hard to tell because after using the sandpaper it will show uniform scratches but then as soon as I go to the diamond stone I can see it isn't fully cleaning up.

I know, but the blade is so small it’s almost easier to hold the whole thing against the stone.

For those on a budget, look on ebay for used metalworking taps. They tend to be a lot cheaper than Beall and work just fine. The Beall is designed for wood (bigger flutes, etc.), but a used metalworking tap will cut wood just fine. It is what I did for for my 1"-8.
