Left Stepper Not Working

I am Discord dumb and don't really know how to do this. I am wiring my RRVC3 - 400mm. All three Z motors working fine. Right motor working. Left motor not working. Can't figure out why. Swapped cable from right to left and it moves so it is not a problem with stepper motor. Cable is good with continuity for each wire from BTT Octopus to stepper. New JST connectors put on all steppers with solid connection.
