I am encountering an error when I try to execute odrive_demo.py.

python odrive_demo.py
fatal: not a git repository (or any of the parent directories): .git
Command ‘[‘git’, ‘describe’, ‘–always’, ‘–tags’, ‘–dirty=*’]’ returned non-zero exit status 128.

What version of the firmware are you using? Some of the new fancy ones use input_pos instead of pos_setpoint

Thank you for your response. I believe firmware version is 4.9, upon start it says “ODrive control utility v0.4.9”. As you suggested, I tried issuing commands using odrv0.axis0.controller.input_pos. The motor does not move or does not throw any errors.
Axis, motor and encoder errors are ‘0’.
Thanks,
A
