I wonder if ST-link would fix it, or if a STM chip swap or other repair is actually needed. They did not really make these Mobo much worth saving imo. Given you are locked into one remote as far as I have seen.
@Ricco You helped me find where there might be a UART port accessible, maybe someone can test out using another remote if they can switch it internally somehow.
I also have a SBX wit faulty battery here. bought is usedā¦
Now I like to repair it in a easy way.
Your solution, to use 2 Lipos and cut them into the case is just cool as f*ck!!!
Maybe this will be my evening project today
Do you have any tips what I should take care of? Or is it just as straightforward as it looks?
Did you remove all the original pcb electronics in the battery case?
Only connected the battery to the mains?
Or do I need to shorten any of those wires? (red circles in the image)
I was curious to know how much it costed him to CNC them. I am designing my own replacement for the V2 casters as a test to see how practical it is to use sendcutsend as a manufacturer service.
The Fork will be made from 3.1mm sheet of 316 stainless and bend into shape.
Disk will be aluminum or plastic and it will be screwed onto the fork with gub screws.
The bearing spacer could possibly be 3d printed for cheap.
the long Spacer that goes through the bearing will either be 3d printed or made from aluminum.
The bottom washer will be leftover from the V2.
The hole assembly will be screwed together with one long screw. I am still debating on if Ill used a nut or make the fork threaded.
I just got my first parts today and they look nice! they were thereās some dimensions that are wrong so I need to make some slight offsets(needed to hammer them together since tolerances were to tight). Major problem was that I somehow fucked up on the instructions and the entire model ended up wider by like 7mm with made it unusable. Not bad for $41 tho.
If this works then Ill open source the CAD for it so others can use it to fix their V2ās. Then Ill design one for the SBX with the stock slipring and baseplate so people can add larger motors and different wheels/gearing. Then Ill look into getting my own custom sliprings build that Ill use with the Otherbord M1 caster. Hopefully at the end of this Ill have a fully customizable ecaster that will work with almost any combo of gearing/motors/wheels. This is gonna be fun. Iām excided.
So after some sessions, Iām now confident with my SBX so tried some speed test.
At full throttle with the 4S LiPo I canāt reach more than 27km/h.
So next upgrade is two new 6S LiPo. Just need to check for the discharge if 40C is enough or not.
Iām in love with this board!
Maybe, next upgrade will be a swap on a 5X freeboard but I need to test one before.
VESC swapping will be done if I change to a freeboard 5X. I already check the SBX supermod topic, the Xenith vesc looks so cool but damned itās expensive.,.
Donāt know if there is cheaper alternative or need to go for it.
Anyone have a dead/broken/used SB remote that theyād want to sell?
Great work with the VESC swaps!
But seeing as how dual VESC are on the order of $300 has anyone figured out how to connect VESCTool to a SB ECS to make configuration modifications? Or been able to re-flash the SB ESC with mainline VESC firmware?
Has anyone tried to unsolder the stock Bluetooth receiver and wire in a Flipsky or Hoyt receiver?
If I do need to go down the VESC route, I was thinking of 2x Cheap-FOCer-3ās like @Fosterqc suggested. But I also saw @SpeedDemon ran into communication issues with when he tried this. Iām new to this but isnāt 2x single VESCs a fairly common configuration?
yes, I have done this. In fact summerboard uses a reskinned VESC tool as their app. They released (a while back, pre app) a modified VESC tool to use with their boards. What they call a āmotor optimisationā is a motor detection. I donāt know what they modified on the code to make it work with their custom ESCās but this version of VESC tool is available if you message summer board.
