Please tell me which type of the endstop you use.
Usually, the endstop has two status: NO and NC. Probably its status is incorrect. Press the endstop to check if the motor moves.
If it moves, You have 2 solutions:
1.Reverse the wiring of endstop;
2.Turn the identificaiton into Inverse ...

3 jumper caps should be plugged under each A4988 module. And there should be a jumper cap above the second A4988.

Please tell me the type of mainboard. If you don't know its type. Send a picture to me.
By the way, I will give the wikipages of 2 types of mainboard, where you can find the wiring of mainboard.
