Multiple VESC's in duty cycle mode

Hey everybody,

i have 3 BLDC on 3 VESC. each of them , single connected runs perfect in duty cycle mode. (i need low speed , high power)

If i connect them via can bus, the one with ID 0 runs ok, the others run without power and like in current no brake mode.

Where do i set multiple vesc's via canbus = true ? only on ID 0 ? or on all.

I am a little confused.

Vesc tool v.1.08 .  VESC 4.1

Can somebody help me ?

Thanks in advance

Rudy
