Could use some guidance with limit switches and a prox switch arduino mega

Paul,
I wish I had 1/16 of the knowledge you obtain. How about this for test purposes?

(edits)

  1. I am only really using A1 & A2 for motors 2 & 4
  2. I changed 300000 to 3000
  3. i changed rotation from 90000 900

I don't mind criticism. Please read on, I really want to know what I am doing wrong.
My father once said told me. "If you don't learn something new every day, then you are wasting your time"
Thank You,

As well sir, could you elaborate a little to what you mean here

What's the purpose of reading the switch state?

int i = 900;
int j = 0;

void setup() {
  
  // assign the pin connections for my motors
  
  motor2.set_microstep_select_pins(A1);
    
  motor4.set_microstep_select_pins(A2);
    
 // set the mag pin and the switch pins as inputs:
  
    pinMode (switchPin1, INPUT);
    pinMode (switchPin2, INPUT);
    pinMode (magPin, INPUT);
    pinMode (enablePin, OUTPUT);
    
  // create at start up command procedure to run once
  // i was thinking I could run this from void set up to run once
   
   for (int i = 900; i > 0; i--);                    // Amount of maximum space i can travel changed from 90000 
   motor2.go(FULL, -i, 10);                        // Rotate motor 2 CCW from anywhere power is lost   
   if (digitalRead (switchPin1) == LOW) {  // When I trigger switch left it should read low removed semicolon
   delay (3000);                                      // Delay for 3 sec
   }                                                     // Here it will not exit void setup into void loop
  }   
  
 void loop() {

//at this point switch left will read low and mag pin will be high
//so it should skip the while statement and loop back to it when the statement is true at the end of code 
//also I am testing only motor 2 in this sketch for simplicity at this time
 
 for (int x = 0; x < 20; x++);                         //repeat 20 times 
 while (digitalRead (magPin) == LOW){           //read prox switch low when interrupted
 motor2.stall ();                                        //stop motor
 delay (3000);                                       //delay 5 min
 {
 for (int j = 0; j < 900; j--);                     //amount of maximum space i can travel
 }
 for (int x = 20; x > 0; x--);                         //repeat 20 times 
 if (digitalRead (magPin) == HIGH){               //prox switch pin is high until triggered
 motor2.go(FULL, -j, 10);                         //rotate motor CCW until prox switch is triggered
 }
 else {
 sensorValue = digitalRead (magPin);          //read current value of prox switch should be low 
 delay (3000);                                    //delay for 3 sec changed from 5 min
   }
  }
 }
