(SOLVED) Motor Stepper not Spinning - Balancing Robot with UNO and CNC Shield

[jimmyjr2023]

Hi again, now I'm building a self balancing robot with MAHOWIK BalancingWii Firmware. I use Arduino UNO and CNC Shield. Besides, I also use NRF24L01 that is integrated as I did with My Mini Drone project long time ago.

What progress:

1. Successfully uploading sketch, PID Tuning, Integrated NRF24L01 receiver.
2. Successfully controlled the robot using NRF24L01 transmitter (including Arming, and control all channels, including AUX1 and AUX2
3. Power supply: 12v/2 Ampere

Here's the PID Tuning using multiwiiconf GUI 2.3:

NExt, this is when connected to Transmitter:

This is when Arming:

PROBLEM:
THE MOTOR STEPPER NOT SPINNING AS SOON AS I ARMED !

QUESTION:
Since it is the first time for me to use CNC shield, in my opinion, all wiring is handled by CNC shield, right? and I just connect 4 wires of stepper motor to 4 pins next to the motor driver?

Here's the pic of CNC Shield. And, please let me know what should/must I connect or wire besides the two PINS of Motor Driver.

I use DRV8255.

Solved! LOL, I got wrong on connecting step and dir and also 1A-1B, 2A-2B (WIRING PROBLEM).
