odrive has no error
I set all motor parametes, encoder and performed FULL Calibration command then, CLOSED Loop control command. AXIS1 is working great but Axis0 doesn’t hold it’s positon.
So Axis1 works when do positon command, Axis0 doesn’t…

I have two odrive and both have same problem.

Anybody can solve this problem?

Thanks

Have you tuned your control gains yet?

I have not changed anything about control gains, should I change it? Thanks

It’s hard to tell but it look like one motor has a lot more friction on it than the other. Make sure both motors work before you mount them in the device, then mount them & tune the gains.
