I had this setup running really nicely until yesterday. I have the same settings as shown in the above examples. Yesterday I was riding allot and a few times the slave motor wouldn't spin on startup, I restarted the board and things worked fine, then nothing at all. I've been troubleshooting all night and got the motor going a few times then it would stop responding and now I cant get anything from it.
I've checked and re-soldered the CANBUS connection, the VESC is on with blue lights (good) and the motor spins on the detection test in BLDC but I can't control the second motor using my GT2B which is connected to the master VESC, Im not getting any pulse width readings in the PPM app, however I do if I am connected to the master VESC.
I'd love to hear any suggestions so I can get this thing back up and running for the weekend, single drive sucks after you've experienced the wonders of dual rear
