I have a legacy focbox that I bought last year and finally got around to trying to set up this week. Didn’t go well.
I hooked up to a 30A lab power supply at 27V. I tried doing the motor detection stuff in the BLDC tool and it failed. Upon doing some further research I realized that I shouldn’t have anything connected to the motor when I do that, so I powered down the power supply and removed it from where it was installed, positioning it on the bench to configure.
I then turned the power supply back on and plugged the USB cable in, and as I was reaching for the mouse to connect to the FocBox in the BLDC tool USB port on the FocBox caught fire. I’m not sure how extensive the damage is given the blue light still comes on and I can’t see any visible damage to other components, but I’m not able to use the USB port anymore. (Actually hosed that USB input on the PC too, which really sucks.)
Enertion doesn’t have any more of these, so I’m SOL with them.
A few questions here:
Before I try to solder a new micro USB port to the board (which will be a challenge): Is it possible to configure this thing without USB?
Anyone have thoughts on what might have caused this? I’d prefer not to repeat the disaster if I get the board working again.
PS - To the extent it matters, this isn’t being installed in an eSk8 application, but this is clearly the land of experts when it comes to VESCs and BLDCs. I hope you guys don’t mind.
