I have just finished building my 4 wheel drive mountainboard, using 2x Flipsky Dual FSESC 4.20.
Both VESCs are connected via a CAN cable.
Each of the 2 VESCs is powered by a seperate 13S LIION battery.
All 4 motors on the board worked just fine for a few hours, until 3 of them suddenly stopped working while driving. The board can still be driven, but only one motor still works.
I have now tried to reconfigure the VESCs again, but did not have any success.
Using the VESC tool, the Master VESC (remote is connected here) does only detect 1 of the 2 motors at a time. (rear axle)
The Slave VESC still detects both connected motors via VESC tool. (front axle)
I have tried resetting the Firmware, but this still dod not help.
Is there any possibility, that my Master VESC (CAN-system) is permanently damaged?
Can the problem be, that both VESCs are powered individually?
I have read, that the CAN-system can be damaged under specific circumstances.
It would be great to get some support, as I don't really know how to detect the mistake.
Thank you very much!
