Hi, i’ve got the V1 motherboard and V1 batterie. My issue is at every boot or reboot all my parameters back to default one… i have to connect to the app to change it every time. I don’t know if someone here have the same issue or a solution…

@STL I haven’t seen this issue myself, but I’ve heard other people report this on the Facebook group. Summerboard asks people to send their Motherboards back for re-flashing. I couldn’t find any reports of this issue on VESC Project forum. The code with respect to EEPROM doesn’t appear to have changed much, other than a minor address update.

Based on the symptoms, I would think this means that your EEPROM has corrupted. Possibly voltage loss? Even in VESCTools itself I don’t see a way to erase the EEPROM and factory reset it.
If this were my board I would try to manually erase the EEPROM with an STLink.

#Dump your entire STM32 contents
st-flash read dump.bin 0x8000000 0x100000
#Use a Hex Editor to write data 0xFF (erased) to addresses 0x60000 to 0x67FFF
#Flash erased EEPROM back onto STM32
st-flash write dump_w_eeprom_erased.bin 0x8000000
Just for reference this is why my EEPROM contents looks like:
Unfortunately I don’t know of an easier potential solution other than going in with an ST-Link.
Luckily ST Links are super cheap and solder pads are not too hard to solder to.

I’m working on a lowrider casterbase for my SB-XL (summerboard/ e-freebord with big wheels). For the ones that don’t know my build:
My last setup rides very well however I would like to get the center of gravity as low as possible in combination with the big wheels. To make this possible I’m designing a new casterbase to replace the SR360 that I’m using.
First print of the design to toy around with:

If I get it to work the riding height will be pretty much the same as a normal SBX.
The idea is to integrate the bearingblock in the deck of the board to save space.

I just bought a used summerboard and while doing maintenance on it I noticed that the caster’s plastic base is badly cracked.
Does anyone have a .stl or (preferably) .step model for that? Maybe @Fosterqc you have a model?

Also does anyone know what bearings the caster wheel’s axle uses? I will need new ones soon and I don’t want to disassemble it just to check if it’s not necessary

Same as edge wheels. Just make sure to get bearing with a double sided seal. Single sealed bearing die fast.

Thanks, that’s perfect!
Hi, sorry that I can’t help you with that… I saw people fixing the broken base with epoxy and claming it was better after that. Coolest would be to DIY… other option is to contact summerboard and order new ones. They are not super expensive. Hope you get it fixed!

For now I just superglued all the pieces back together and reassembled it. I had a ride today like this and it seems to hold so far, but I don’t expect it to hold up long term.
I will DIY the replacements for sure. Ordering wouldn’t be ideal because shipping and taxes to the EU would be expensive for sure. I have the skills to 3d model and print a replacement part, but it’s a lot of work so I would wait until the weather becomes completely unusable before disassembling it for modeling. But if someone already has a file I would be grateful if I could skip all that design work
Also on an unrelated note the stock remote’s battery life is absolutely miserable. Granted I was going slowly because it was my first session, but it gave out in like an hour and a half, way before the board’s battery. I’m gonna have to do something about that too.
Good luck! 
Have you thought about designing a completly new e-caster? Love to see new ideas

Thanks! I thought about designing my own caster from the ground up, but I will wait with that until I buy a CNC machine. I already have way too many ongoing and pending projects for now, especially when I factor in that I have a part time job next to studying at a university

I have seen one or two people model it but didn’t share the file… This discouraged me from making and sharing a file paradoxically. I started trying to work out the dimensions but it is a huge PITA.
If we got it scanned that would help, not sure how to make that happen.

Ah alright!
Yeah well I don’t have any measurements yet. When the weather turns unusable I’m going to take it apart and take some measurements. I’ll share the measurements when I have them, but I will also just start modelling it myself probably. There’s still some usable days for the season plus I want to have as much practise on the board as possible before I go snowboarding in early December

yeah bit tricky when you have to almost make two models, the one that matches measurements and one that correctly 3d prints a replacement.

My remote got fried by just keeping the USB charging overnight. See pictures. Not sure what component this is that got fried but I want to find more reliable aftermarket remote options.
Does anyone know of any other remote compatible with the summerboard? I am happy to buy a couple of remotes and report back to the forum on what worked. I am not familiar enough with this ecosystem to know where to start. I come from an FPV drone racing background so I can solder and tinker in general but I don’t know enough about the RF systems used in the e-skate ecosystem.
I tried the VESC configuration app and it is able spin up the motors so it is hopeful that they are using somewhat open standards.
Thank you in advance!
I can’t embed pictures or share links yet.
getting a good scan is it own kind of difficult trust me.
First attempt at scanning/modeling it. Ill likely try this again in the future. This model is basically a blind reconstruct from the scan. I didn’t doublecheck dimensions on anything. If you want to mess around with it or use it as a reference then feel free.

I strongly doubt that any other remote can be made to work with summerboards proprietary esc. also be careful using the vesc app with the SBX esc. I bricked mine while making changes to it using the vesc app.

Wow good to know. Thanks for saving me the trouble. How did you end up unbricking it?
