Stepper motor vibrates but does not rotate

Hello everyone,

I am using a 12V 6A power supply, I set the Drv8825 driver current to 0.7 and put three jumpers under the driver.

The motor model I am using is: 17HS13-0404S from oyostepper
, step angle 1.8, size 48, rated current (A) 1.7OHM 1.8MH 3.2, holding torque 52, positioning torque 2.6

I edited two lines in the code:
#define DEFAULT_AXIS_STEPS_PER_UNIT { 200, 200, 800, 200 }
Replace with:
#define DEFAULT_AXIS_STEPS_PER_UNIT { 100, 100, 800, 100 }
And the bed size:
#define X_BED_SIZE 200
#define Y_BED_SIZE 200
Replace with :
#set X_BED_SIZE 1220
#set Y_BED_SIZE 2440

When I select motion in the LCD options and try to move any axis, the stepper motor vibrates but does not rotate.
What should I do to fix this?

Your stepper plug may be wired differently than the board is expecting, that would cause what you’re seeing.

try swapping the motor wires green and blue on one side. if your cable has a dupont connector it is very easy
