I have designed two new ZESCs, but don’t know when I have time to resume my bussiness.

and the raiden 8 we’ve all been waiting for

Any chance that this f/w can be built for latest VESC release?
Having an issue with inductance detection for Hummie hubs using these.
Worked fine with FocBox OG HFI, now I can only get BLDC detecting
Looks like surfdado added these ESCs to the official project
If it doesn’t update through the tool, you should be able to manually load the firmware files from here

nice! thanks
Try fiddling with current limit during detection. Usually helps

I ended up charging battery 4.0v nominal, checked any existing setting swore a little then used the wizard & the problem went away, giving my cursing the win here but thanks

Meant to ask. The ZESC Warrior 6’s I have appear to be on a beta f/w. This is the latest release from the designer before he went on his hiatus.
Using the latest VESC tool 6.0.2 I get this
There is no suggestion for F/W to upload at this point
Not sure if that merge on github helps in that department
Do I need to make a build from src or pull a fork or…

Oh, easy fix
Download this file:
Then:
Firmware → Bootloader → Upload
Firmware → Custom File → load github file → Upload

thanks 6.0.2 went on effortlessly
Not so smart was attempting to change the switch for a LED switch with the battery stilll plugged in. Ignore spaghetti BMS wiring which was next on list
This one will not turn on at all even with USB plugged in - not sure if the controller is damaged or just marked?
Think this is a voltage stepdown regulator/buck? They are both damaged in this way.
The other one will turn on if the switch is ON & the USB is plugged in. It will not turn on without USB power, the same antispark(?)component is damaged also
Maybe I can I repair this? Anyone have a clue on the matching component from Farnell, DigiKey or Mouser
Looks like a TI LM5017, but it’s hard to tell for sure with that lighting.
LCSC has some in stock
Hot air and some Flux (AMTECH VS-213-A-TF works well) should be able to replace that. NorthridgeFix on Youtube has a ton of good videos on chip replacements. Like Louis Rossmann but does a lot more repairs.
A few things you can check along the way
3.3v to GND - if it’s short then it could be the buck, canbus or STM32
5v to GND - if it’s short could be the bucks
Resistance between phases should all be the same, if not can point to shorted mosfets.
Would be helpful to see the full PCB to see the whole layout. There are likely a few bucks on the board.

I use that flux its good as heck.
For sure check if 3.3V is shorted, sending 1 amp down the 3.3 and seeing if the STM32 heats up also is telltale.
Wish I had someone to split DHL shipping from LCSC

Have to say I’m impressed with the quality of board assembly I am seeing…let’s see if I can rectify this
