Hey VESC guru’s. I decided to switch my 4WD hub motor board from split servo PPM control to 4wd CAN bus control last night and lost 2 of the 4 VESC-X’s I was using. I’m pretty sure the CAN tranceivers are toast. Both VESC’s are lights out and the C25 CAP is getting hot. This same issue happened when I used CAN to control my TB VESC’s. I thought I was over using CAN bus after the first incident but making adjustments to all 4 VESC’s is so time consuming and I have a micro USB extension from the Master VESC that would allow me to adjust all 4 through the side of my enclosure had this worked.
I’ve never had issues running two VESC’s via CAN bus but running four seems to be problematic. Anyone else have any insight on this issue?
FYI I already triple checked my CAN bus harness there are no issues with it. I’m confident its Vesc hardware or firmware related.
