Strange behaviour when both axis start

#1

Hi!.
I started to setup the hoverboard example.

All is fine until i try to start both axis like this:
odrv0.axis0.requested_state = AXIS_STATE_CLOSED_LOOP_CONTROL
odrv0.axis1.requested_state = AXIS_STATE_CLOSED_LOOP_CONTROL
odrv0.axis0.controller.vel_setpoint = 120
odrv0.axis1.controller.vel_setpoint = 120
It worked once. But most of the time axis0 turns off when axis1 turns on and vice versa.

The part with the RF receiver has the same behaviour. I cannot start both axis at the same time. It is one or the other.

Can someone please give me some advice? Have you encountered this issue before?

Thanks

Have you solder capacitors to encoder Odrive inputs?

No. I did not!
But in this case i was expecting an encoder error . I will add some caps and post an update. Thanks
