New to cnc. Gear motors not rotating

I bought maker made cnc and built frame and downloaded all the steps and I can’t get my chain motors to sync up and rotate please wanted to start cutting today could use a experts help.

Check that the power supply is plugged in the top (motor-shield) and not in the bottom (arduino).
Check if the LED on the power supply is lit.

So I went back out this morning and confirmed I do have it wired correctly. My left side is plugged to 3 and right side is plugged into 1. When I go to calibrate it does not rotate the right side moved a little bit but now neither are moving

which board is the black power supply plugged into? it should be going to the top board. same board motors cables go into, a photo always helps trouble shoot.
