Hi All,

I finished installing J2 and J3 stepper motors. J1 and J3 turn smoothly without any pressure, while J2 is not smooth and seems to click when manually turned. I removed the motor from the gearbox and inspected the inside but nothing seemed misaligned. My knowledge of stepper motors is beginners level so I'm not sure what to look for except via general observation.

Are J1 and J3 different motors than J2?

Is J2 supposed to click or spin freely?

Thanks!
