Adafruit MotorShield 2 servo's+ 1 stepper code check please !

Hi there,
I’m lost
I want to make an animation with a Uno / Adafruit MotorShield / 2 servo’s / 1 stepper (4 wires)
with USB power on the Uno and a 9v external power supply at the Uno
First I’m explaining what I want to reach.

-First servo1 must go turn from 0 to 90, back to 0.
-Then the stepper must turn a few turns forwards
-Then Servo 2 must turn 90 to 0 left and 0 to 90 right turn
-Then the stepper again a few turns backwards
-Then servo1 must go turn from 0 to 90, back to 0 again.

After a lot of days testing, this code was working on a low voltage stepper, now I exchanged it with a 9 volt Lego stepper motor that’s looks like to work but the stepper takes a run at the end.
Can you people check my code please or have a idea what is going wrong?
I like to hear from you.

Code:

#include <Servo.h> 

Servo myservo1;             //  licht aan,licht uit            
Servo myservo2;             //  hand zwaait
              
int pos = 0;    

#include <AFMotor.h>

AF_Stepper motor(50, 2);   // zwaai arm omhoog en omlaag  



const int LED = 3;


void setup(){
 
Serial.println("Licht aan");
myservo1.attach(9);  // attaches the servo on pin 9 to the servo object 
 for(pos = 0; pos < 90; pos += 1)  // goes from 0 degrees to 180 degrees 
 {                                  // in steps of 1 degree 
   myservo1.write(pos);              // tell servo to go to position in variable 'pos' 
   delay(15);                       // waits 15ms for the servo to reach the position 
 } 
 for(pos = 90; pos>=1; pos-=1)     // goes from 180 degrees to 0 degrees 
 {                                
   myservo1.write(pos);              // tell servo to go to position in variable 'pos'

Serial.begin(9600);           // set up Serial library at 9600 bps

What is "a run at the end" ?

keeps turning.

After a lot of days testing, this code was working on a low voltage stepper, now I exchanged it with a 9 volt Lego stepper motor

Please provide technical details of the two stepper motors so we can see if the difference in their specification is the cause of the problem.
