Can not make the engine spin

hello everyone i am new
I use smc3 v0.6 code (I do not edit anything to upload to my uno arduino and diagram under the attached photo template.
I can not make the engine spin.
I do not know where I was wrong.
Please help everyone.

completely original code
//****************************************************************************************************************
// SMC3.ini is basic Motor PID driver designed for motion simulators with upto 3 motors (written for UNO R3)
//
//****************************************************************************************************************

// Set to MODE1 for use with a typical H-Bride that requires PWM and 1 or 2 direction inputs
// Set to MODE2 for a 43A "Chinese" IBT-2 H-Bridge from e-bay or equiv

#define MODE2


// COMMAND SET:
//
// [] Drive all motors to defined stop positions and hold there
// [Axx],[Bxx],[Cxx] Send position updates for Motor 1,2,3 where xx is the binary position limitted to range 0-1024
// [Dxx],[Exx],[Fxx] Send the Kp parameter for motor 1,2,3 where xx is the Kp value multiplied by 100
// [Gxx],[Hxx],[Ixx] Send the Ki parameter for motor 1,2,3 where xx is the Ki value multiplied by 100
// [Jxx],[Kxx],[Lxx] Send the Kd parameter for motor 1,2,3 where xx is the Kd value multiplied by 100
// [Mxx],[Nxx],[Oxx] Send the Ks parameter for motor 1,2,3 where xx is the Ks value
// [Pxy],[Qxy],[Rxy] Send the PWMmin and PWMmax values x is the PWMmin and y is PWMmax each being in range 0-255
// [Sxy],[Txy],[Uxy] Send the Motor Min/Max Limits (x) and Input Min/Max Limits (y) (Note same value used for Min and Max)
// [Vxy],[Wxy],[Xxy] Send the Feedback dead zone (x) and the PWM reverse duty (y) for each motor
// [rdx] Read a value from the controller where x is the code for the parameter to read
// [ena] Enable all motors
// [sav] Save parameters to non-volatile memory
// [ver] Send the SMC3 software version
//

// Arduino UNO Pinouts Used

I want to build 3dof following model.
But programming arduino for me is very difficult.

Thank you.NOORBEAST
may be to add time for reading instruction.
