i broke my smith forefront helmet yesterday. i took the fang minis off my xr cause they keep twisting around with the bang bumpers, and i took a corner too fast on the local singletrack. i guess the nose digged in, and somehow i flew off the board and managed to roll backwards on my back, and then bonk my helmet on the trails from the back. earbuds went flying out, and my helmet cracked pretty big time, though my head did not. i guess i needed a new helmet anyways :)

i put the fangs back on, turns out they are super useful even on dirty trails.

@Lia um i found the issue. any tips how to repair it? the xr battery has some extra glue around the wires i guess to prevent this from happening. the jw one does not.

since it deep in snowbo season right now, i just wanted to drop in and comment that i am a total spead freak on the snowboard, but i don't really push past 16mph on the onewheel. maybe go a little crazier on dirt trails, but pavement, hell no. snowboards won't turn off on you like the onewheel! fuck that

@maciak i just had this happen to me on my jwxr with ffm chip 4212 at about 50v ~37% battery going about 12 mph on the street. no pushback just lost power all of a sudden. i managed to ninja my way into a sprint, even with flightfins, without breaking any knees or legs. board showed error 16.

lately i've been seeing a bunch of error 16's sometimes, always at low speeds and sometimes with pushback. first time ever that i got ejected. it's been charging weird. the jwxr has a weird way of charging, but i often need to uplug the charger and plug it back in a few seconds later cause it seems to randomly stop charging. i don't know if that's related, didn't do that before.

i remember the mesh protection of the wire going from the controller to the battery has some wear. is that the cable i should be checking for issues? i guess with a voltmeter?

(i installed my jwxr in october of last year and it was pretty rock solid, didn't see my first error 16 until january this year and i was riding almost daily)

thanks

@notsure yeah I'm hindsight with all the crap I've been through with the pint and now the XR, I don't think I'm messing with the battery again. I'll probably go gt and leave it battery-stock.

@Lia any thoughts from the expert?

@lia also, looking at some installation pics from Oct, looks like those two wires were already a bit loose to begin with

all this is live, so it's a bitch to work on! i touched those two together really briefly and it sparked pretty bad 8:

@lemur amazing. i wonder how it feels compared to the kiilguards setup

@Lia i tested the harness cable and it's pretty solid at 120.3 ohms. gotta a vid too but not sure how to upload it here. gonna crack open the bms and see what's going on. i also have a newer ffm chip with upgraded firmware (something about a fix that performs pushback when there's a bad battery cell instead of shutting off) so i might as well swap that one in. i think my soldering skills are better now, as well as my tools.

flashing was a pain and not working until i realized i had a bad usb cable lol. then it flashed beautifully. got it all nicely soldered in (was weird that the green wire from the connector was to be left disconnected for this install!). and it works! though he's only getting stock range (it's a jwxr battery), so seems Mike needs to do some more homework. oh and this is with a new (used) BMS.

@lia ok i just finished resoldering the new ffm chip on and now just waiting for the badgering glue to dry so i can pu't it all back together again. i bought some resin core solder - this was the magic key i was missing to make perfect solders! the jw instructional videos were just using flux and that was really hard. if it was a bad soldering connection, which is possible cause my old job was garbage, hopefully this will alleviate the issue.

@lia so i've been rocking the stock battery the past month (with ffm chip that jw assured me was a no-op with a stock battery) and i came to really trust it again. no issues. well, except a tiny error 16 a couple weeks ago after i got home and was just opening the gate, at an almost standstill. i didn't think much of it.

today i was riding back home and diverted onto the grass to avoid an old lady on the sidewalk. it dumped me just as i was heading back onto the sidewalk. i thought i must have hit a hole in the grass and then kept going.. about 10 seconds later, while rocking the sidewalk, it threw me off without warning. i was able to ninja roll both times, and only lost a bit of skin from my palms and some minor bruises. phone read error 16, and i bet that's what caused the first fall, not a hole.

i rode super slow all the way home like a noob. no more cutouts occurred.

so what the fuck? i'm gonna rip it open again. if i can't find anything wrong with it, i might just rip out the ffm chip and then roll the dice a little bit more again, maybe on dirt rather than pavement.

what other faulty things should i be looking for? maybe some crapped out capacitors on the bms or something?

@lemur said in Suspension board upgraded.:

@swinefeaster I had a set of Kiilguards 6.5 and I really didn't like them because of the spring shocks which were hard to tailor to my light weight and I had to get a custom light springs.
In most applications, spring suspension is not progressive, but I see Kiilguard offers a new setup with shorter air shocks.
In my opinion, the setup really didn't look very good, and the sliders were exposed to the elements.
For a Onewheel application , one shock is more than enough, although the Kiilguard design, there was no choice but to use dual shocks.
I sold the Kiiguards and designed my own.

hmmm fair enough. do you use your suspension for smoothing out the bumps or for drops? i do a lot of drops, so i need the extra travel. i know what you mean about the sliders, i'm on my third set of bearings already.

@lia you're awesome thanks!

@lia thanks!

"The data connection that causes E16 is the green and white wires on the 16 pin battery connector that hooks onto the controller"

I need to open up the controller for this, correct? (Just clarifying)

So my buddy is getting this error on his board, and it throws him off and then he has to power cycle it. Anyone seen this before? @Lia

Also, to give context, he tried doing a jwxr install himself about half a year ago and he fucked up and shorted one of the chips. Then a local repair shop did some sketchy (?) work to repair it.

For example, what is this white wire?

thanks

@lia damn i hope you heal quickly. i'm still suspiscious of my wheels after being ejected from the xr from error 16 onto pavement last week. it's one thing to crash because of the terrain; another to crash because the board turned off unexpectedly.... always a challenge to trust again after you get dumped ;P

@lia oh I see thanks!

How do you recommend fixing my test leads issue? Should I use a piece of wire? What do you use?

I'm going to do a bit more research on how to do volt meter ohm measurement, probably I'm using the wrong last jack combo?

@lia said in Error 22 Incompatible Hardware Detected:

where

Thanks Lia what's a "balance connection"?

I'm thinking this whole BMS is bad news. Where would you recommend my buddy goes from here? Buy a used BMS somewhere? Or get an non-FM bms and an owie chip? (if so where would we start?)

@lia of course i did that actually out of paranoia. i am gonna ride stock and see what jw says. i have no idea on how to fix these.

Hw is 4212. But it's the original BMS and matching controller.

Since it's intermittent, shouldn't he get a new BMS?
