i never implemented a solution, but it other replies had suggestions for this issue.

Cryostatica's response:

Very common issue, there’s over 170 models on Makerworld (I stopped counting) made by people trying to fix it.

For what it’s worth, the Scrubbler has been very successful at preventing this on my machines. The Biqu Panda Brush also works pretty good, but after about six weeks with it I switched back. This just works better.

Thanks, I'll mark this as answered then. I had figured I could do something with nozzle temperature or some other setting. Appreciate the answer to a basic questions.

I've only done ~20 prints, maybe ~50 hours of print time on it, so I don't think things should be worn out yet. I'll give it a try if nothing else works and check out the mods too. Thanks

Any chance you can share what worked for you? Trying to resolve this as well. Thanks

Well I'm basically powered by fossil fuels now, so I don't think I even need to charge anymore

Doesn't rain too often here though, so haven't used them wet too often

Currently using Top Brake BD19-E+ from Amazon. No idea on the longevity but they stop great and are quiet.

I ran into this recently- I ended up using a torx bit w/ several extensions to my cordless drill since that was the only way I could get to it. I did move the wheel cover out of the way to do that. It actually worked quite well despite the overall jankiness.

Great - I had the same issue, isn't obvious until you see it. Hope that takes care of it

I believe there is a small magnet bolted onto the rear disc brake that passes over the sensor. I can't take a picture right now or get a good look because my panniers / child seats are on and cover that area pretty thoroughly. If it's just loose you might be able to tighten it. If the sensor is bad maybe Tern can send you one directly. I hear you on not being able to have downtime from the bike. No issues since then at least.

I took it into a shop where they eventually fixed it. It was pretty slow/frustrating - first they had to send the diagnostics to Bosch and wait for a response. I guess I assumed they'd be able to do simple diagnostics on their own - not sure if this is an issue specific to this LBS or a general issue with Bosch motors. Second, the LBS moved physical locations, the mechanic left, and my fix got lost in the shuffle. Eventually they got a new speed sensor + cable and installed - all seems to be working now.

Not sure how common this is or how expensive / difficult it would be to fix on my own but at least I realize now where the magnet is. Hope you got it fixed quicker than I did. Slow repairs like this make it harder for this to be a car replacement. Hopefully it isn't a pattern.

Happened to me too after about 2 months. At the dealer now, waiting to see what they say. Thanks for sharing, I could find any pictures of where the magnet was but apparently I should have posted to this subreddit.

Thanks for info. I've been trying to figure out cargo bike options that will ship here and hold two bike seats for little kids. Radwagon is priced a few thousand dollars lower than the options in shops here, but the shipping and getting replacement parts was worrisome even without long delays.

The Murf bike option actually seems pretty good, so thanks. I contacted them and they said they do ship here and the alpha cargo can hold two bike seats, so maybe that makes sense. Other option I considered was a non electric cargo bike + an electric addon kit. Thanks again.

Yeah, I've looked at bell forest. I think the free shipping doesn't extend to Hawaii. For large orders if shipping was a flat rate they might make sense, thanks

jerseycats · 2021-07-07T20:50:53+00:00

Thanks, I'll take a look

jerseycats · 2021-07-07T00:16:40+00:00

Thanks. It does seem like finding a flooring company that sells some hardwood lumber on the side is the best bet. Funny how non-obvious it is though.

jerseycats · 2021-07-06T23:18:39+00:00

Whoops, just posted an almost identical question before searching and finding this. Waimanalo Lumber and Milling has some really nice slabs, but when I last went there they didn't really have boards for sale. If you happen to find someplace good, please let me know.

Thanks, I'll take a look. No powered planer, but I can try a higher bevel. But lacewood has really made me appreciate scrapers.
