Two most common problems are:
1) Miss wired steppers.
Ignore all color based guides.
Steppers contain two coils. You need to find which two wires make up a coil. Plug one coil into pins 1 and 2 and the second into pins 3 and 4 of the stepper connector. It doesn’t matter which way around they go, the motor will just turn the wrong way which can be corrected in firmware or turning the plug around 180 degrees.
2) wrong voltage.
For reasons I cant understand people keep plugging 5v into the 12v 5amp power plug. This wont hurt the electronics, it just wont be able to move the steppers.
