It’s not that it’s problematic, maybe I just have too much faith in Maker-X
Edit: faith in Maker-X not for naught. Without a FW reflash I got everything to work somehow.
Only things I did different were hitting “apply config” multiple times, doing motor config with remote unplugged, and splitting the receiver cable to both PWM ports, because for some reason one wasn’t making both wheels spin.
I know I’ve been sleep deprived recently but I feel absolutely retarded right now. Like the board works perfectly but FFS it took me 3 days to figure this one out and every single “issue” is something I’ve solved before. The hubris is almost painful.
So here’s a very late update on the status of this.
So back in December I stupidly rode in salty wet slush conditions. One of my motors seized and I walked home angry. I forgot about my board for a few days, now the ESC will not power on at all. The BMS shows no signs of life over BT. The motor is still gritty and seized AF and I’m pretty sure all the PCBs in the enclosure are fucked. Haven’t tested the battery yet but at this point, I don’t see much use in salvaging anything besides the gear drives and trucks. The budget for repair is looking like about $600 plus a battery rebuild, or I give up on that and just buy a battery. Heck, why don’t I just give up on DIY as I clearly can’t even make something that can withstand a city road? I should really sell everything esk8-related I have and maybe be able to afford a used Hoyt or Lacroix. At least if the esk8 is built well I can fix almost anything that happens to it, but I can’t seem to fix my own stupid build because it was built stupidly from the start.
It was a sad day, and I’ve been pretty much too depressed about this board to even look at it.
In memoriam, this board was fun AF. Consistently was able to hit 60kph going up any incline found in my area, flat, around corners, anything. Torque for days, felt like only moments to get to top speed. Turned like a car but rode like a longboard. Gonna miss you Theseus, you made 2022 bearable.
the future is looking to be split evenly between an eMTB build and a hub build. not sure which will be done first. be on the lookout for someone the parts I’ve mangled in this thread becoming available for sale whenever I get around to it.
Sounds like your motors can be repaired pretty well, most likely your esc is fine so its only the bearings in your motor and your battery.
Stop being salty, saltyness dont change things (believe me i know) and fix your shiiiit. In all honesty you probably enjoy the reparing as the riding. Learn from your mistakes and do it better!
And if you dont enjoy building/repairing its best to buy a premade indeed. 600 bucks can already start you with something nice imho.
Tell that to my board. I’m about as salty as it got from the roads.
This would be a miracle. In the dark corners of my mind I have memories of my DV6 going up in a giant puff of black smoke. I just feel like that also happened to this D75 after getting the Aquaman treatment but I didn’t notice because rain/depress
I still have that drive, but I feel like I need to pivot away from underslung enclosures and high end sleek show-y builds. If my ESC is salvageable it’s going into a Pelican Case.
The DV6+ seems okay. Just flashed FW6 on it to be safe, and as it’s going to be set up from scratch again anyway, and it seems I can’t get 6.0 because VT6 keeps aborting it. Guess I’ll stick with FW5.3. motor functionality seems fine. Have yet to test UART and PWM.
Metr.pro seems to be dead. It’s sitting in alcohol and I’ll revise this when I know more.
One of the motors and drives seems okay, the other one is seized in multiple places; one of which is the large gear bearing in the BNM1 and the other is something inside the motor, TBA.
The enclosure has gone to a friend for reinforcement and finishing work, I’ll hopefully get it back in a stronger shape than the cracked mess I handed him.
Remote, idk. Willing to get a whole new remote or something if I can save enough on the battery.
Speaking of the battery, this was really defeating. I had checked the LLT app a few days after the incident but I was stupid and neglected to plug the battery in. Due to whatever problems were already present, all groups drained below 1v. My single cell bay charger doesn’t seem able to revive them. It’s a sad day and makes me want to shy away from battery building, especially with more pack makers operating in my country recently.
Will probably be selling my spot welder and LiPo packs.
I’m not entirely sure. The metr had some corrosion under the heat shrink but the VESC was perfectly clean and the battery only had slight salt residue on a single contact at the opposite end of my board to the metr.
My guess is one single little drop made it’s way in on both ends and did it’s damage to the first things it touched, which happened to be a metr.pro and half a p-group.
This just goes to show that “doing your best” at waterproofing just isn’t good enough. Aim for a hermetic seal, if you fail you’ll still have ingress protection.
I’m doubling down on my waterproofing efforts with this rebuild. New seals, better seals and more/better gaskets and glands.
With my earlier flat bottom esk8s, I usually still had slow water seepage into the enclosure even with water resistant approach (never meant or even tried to make the internal compartment completely waterproof).
So it could be that the water is slowly over a longer period of time worming it’s way in from different spots, like for example based on mounting screw locations, with more clamping force nearer the screws resulting in a tighter/better sealing fit and then opening up/loosening the fit a little bit between the screws.
That’s why I’m doubling up the seals, and I have more fasteners holding the enclosure on than needed for the sole purpose of having less “gap space” and more even clamping force.
Small update, I wired the LLT BMS up to a known good pack—no signs of life on the BT.
this really sucks because I can’t seem to find ANY 12s BMS locally or with any kind of quick delivery unless I’m willing to pay $60 for a dumb bms. I can find all the 13s BMS I ever want but 12s is seemingly rare unless I settle for AliExpress.
I just updated the pack to 13s using a small 10A BMS I pulled off a dead scooter battery and going to try not to brake for the first part of my rides, Does anyone know if I can use a VESCtool setting to prevent braking?
Metr is also kaput. Served me well over the passed few years. Idk what I’ll do for telemetry going forward.
Well, I don’t think any board is meant to survive getting hit against a railing, but darn, that really sucks.
Landyachtz now have the fixed blade, which is just a switchblade without the drop through holes, that you could mount your existing enclosure to. Or if I were you I’d look into Al’s Semendeed, or maybe switch to a basalt deck like Trampa or Kaly.
I’ve had that happen in multiple stormcores on multiple occasions. one time it overwrote my motor settings with 60s on everything. Nevermind the other issues.
Truth.
I’ve had more than one dead bt module for no reason while the bms is fine. they seem to die on occasion, even without salty ingress. weirdly the bms is way more solid than the bt module it comes with.
