Do you guys know a stepper motor that is compatible with Neptune 3 pro ?

Mine looks like it’s locked, it makes a short click but doesn’t move.

I try to open it but don’t find anything wrong.

So two questions, what motor can I buy to replace it ?

And there is a way to fix this motor ? Like, rewind it will make it works again ?

Thank you guys

    You can do some math to identify resolution. Check your FW, quick search got me:

    * Default Axis Steps Per Unit (linear=steps/mm, rotational=steps/°)
 * Override with M92
 *                                      X, Y, Z [, I [, J [, K...]]], E0 [, E1[, E2...]]
 */
#if NEPTUNE_3_PRO
  #define DEFAULT_AXIS_STEPS_PER_UNIT   {80.00, 80.00, 400.00, 380.00}
#elif NEPTUNE_3_PLUS
  #define DEFAULT_AXIS_STEPS_PER_UNIT   {80.00, 80.00, 400.00, 390.00}
#elif NEPTUNE_3_MAX
  #define DEFAULT_AXIS_STEPS_PER_UNIT   {80.20, 80.20, 400.00, 390.00}
#endif

    I guess its 380 steps/mm, but I should go deeper in that and do some math (gear teeth numbers, grub screw diameter) to confirm what resolution is original. Shouldnt be hard if you get all information needed, but still easier to ask them what stepper is that. Since its kinda standard 200 steps/rev would be my bet
