HELP with Stepper Code

hi, looking  arduino coding stepper motor operating system.  i'm complete newbie (old mech engineer) world of arduino , 'c' programming please bear me.

system-  nema17 /100:1 ratio stepper  connected leonardo board via easy driver shield. it's controlled via 2 pushbutton momentary switches (fwd & rev) , 2 limit switches on stepper motor/gear box assy (rev & stop/park).   rev switches connected in parallel, 1 automated operation, other manual intervention/override.

operation- push fwd(go) button , stepper motor runs cw until hits rev limit switch (or manual rev button pushed) , returns ccw stop/park limit switch , stops - total movement 20deg.  additionally, fwd/cw (go) movement speed variable via 10k pot (slowly rotate @ manually set / adjusted speed). while rev/ccw movement runs @ single high speed only. (returns start position , stops).  it has r/g/b led indicators each action/mode.

my difficulties - found during adruino research brian schmalz excellent easydriver examples, 1 of i've used , modified (butchered??).  sadly doesn't work i'm doing huge number of incorrect things within code???  i've read complex stepper codes talking of push button 'debounce' etc, struggle understand require?

if(analog_read_counter > 0)
    analog_read_counter--;
    analog_read_counter = 3000;
    analog_value = analogread(speed_pin);
    stepper1.runspeed();
    current_speed = sign * ((analog_value/1023.0) * (max_speed - min_speed)) + min_speed;
    stepper1.setspeed(current_speed);
    stepper1.runspeed();

}

  else if (digitalread(return_pin) == 0) {
    sign = 1;
    digitalwrite(relay1,high);
    digitalwrite(led_blue,low);  
    digitalwrite(led_green,high);

    digitalwrite(led_green,low);
    digitalwrite(led_red,low);
    digitalwrite(enable, high);  
 
  }
  }

any coding thing work highly appreciated.
wiring diagram attached.

hi,
welcome forum.
thanks reading how use forum message.

have written code @ once or in stages?
that is.

• connected control box , written code read , output leds , got worrking.
• started new code control easydriver , stepper, , got working.
• added limits , got them working.
• combined codes , got them working,

what not working?
