J4 Motor trembling

Hi. Initially, my j4 motor was working great. I have checked all connections, replaced the motor, and it is still trembling when I try to Joggle. Any ideas what could be causing the problem?>

typically when a motor is trembling its the motor wiring for A+A-B+B- does the motor you received from stepperonline have the typical wire colors per the spec sheet here? https://www.omc-stepperonline.com/nema-11-dual-shaft-stepper-motor-bipolar-l-51mm-w-gear-ratio-14-1-planetary-gearbox-9-5mm-rear-shaft-length.html
