PLEASE HELP Stepper Problem

Hello! I just finished building my new 1000mm kit and I am having a problem, my Y2 stepper motor is not working. I checked the wiring diagram and it is all correct. Does anyone have any ideas? Anything is a huge help. Thank you all and have a great evening.

If using xcontroller switch your Y1 and Y2 see if now Y1 is the problem. then will go from there.

Ah! I will try that tomorrow! Thanks for the tip.

I double checked and it is all correct. Thanks for the tip!
