Stepper motor control for high speed

Using Arduino Motors, Mechanics, Power and CNC
#1

Hi there! Could someone help me ? I'm having a problem to control NEMA 23 stepper motor using arduino mega 2560, TB6600 driver and a 12V 10A power supply.
I can't get the electrical specs of the motor but it's 200 steps per revolution, its model is 23HS404-25. I bought it from one dealer who didn't have its data sheet and I can't find it on Google either.
The problem is the motor stalls only at 750 steps per second (roughly 3 revs/s) with no load and stop rotating, vibrate while getting very hot.
I'm using accelstepper library.

I need atleast 750RPM(12.5 rps)

What is the coil current setting on the driver?

What microstep setting?

Post your test code.

#3

I've tried all settings but there was no difference.

#4 
int step_pin=3, dir_pin=2;
static int i=0;
static int steps=4000;
boolean is_running= true;
void setup() {
  
  // put your setup code here, to run once:
pinMode(step_pin, OUTPUT);
pinMode(dir_pin, OUTPUT);


}

void loop() {
 
  
  digitalWrite(dir_pin,HIGH);
 while(Serial){
  if(is_running)
   {
    
   digitalWrite(step_pin, HIGH);
  delayMicroseconds(750);
   digitalWrite(step_pin, LOW);
   delayMicroseconds(780);
   i++;
    if (i==steps){
    
    is_running=false; }
   }
    }



  
  
   

    
  /*delay(1000);
  // put your main code here, to run repeatedly:
digitalWrite(dir_pin,LOW);
for (i=0;i<steps;i++)
  {
digitalWrite(step_pin, HIGH);
  delayMicroseconds(350);
   digitalWrite(step_pin, LOW);
   delayMicroseconds(350);
  }
  delay(1000);*/
}

Blindly doing stuff without a clue as to what they do is not the ideal troubleshooting methodology.

#6 
THIS IS THE CODE
int step_pin=3, dir_pin=2;
static int i=0;
static int steps=4000;
boolean is_running= true;
void setup() {
  
  // put your setup code here, to run once:
pinMode(step_pin, OUTPUT);
pinMode(dir_pin, OUTPUT);


}

void loop() {
 
  
  digitalWrite(dir_pin,HIGH);
 while(Serial){
  if(is_running)
   {
    
   digitalWrite(step_pin, HIGH);
  delayMicroseconds(750);
   digitalWrite(step_pin, LOW);
   delayMicroseconds(780);
   i++;
    if (i==steps){
    
    is_running=false; }
   }
    }



  
  
   

    
  /*delay(1000);
  // put your main code here, to run repeatedly:
digitalWrite(dir_pin,LOW);
for (i=0;i<steps;i++)
  {
digitalWrite(step_pin, HIGH);
  delayMicroseconds(350);
   digitalWrite(step_pin, LOW);
   delayMicroseconds(350);
  }
  delay(1000);*/
}

A couple of tutorials that may help.

What does the while(Serial) do? You do not open a serial port.

#8

Actually I was trying to control the stepper through serial-by sending number of steps through serial. So, "while (serial)" is just a trash left while I was clearing unwanted stuff to leave only the code I tried to use, which gave me only 750 steps per second.
I mean I was trying to use the code with serial while I wasn't happy with the speed I got. So I want to be happy with the speed first then work on serial.

#9

To achieve higher speeds you will have to introduce acceleration. No way around it. You can use a library like AccelStepper.

#10

Before using this code which I wrote myself, I used accelstepper library too. It gave almost the same results: if I put speed more than 600 steps per second the motor stalls, vibrate like it is rotating but not, while getting hot.

#11 
THE CODE SHOULD LOOK LIKE THIS

int step_pin=3, dir_pin=2;
static int i=0;
static int steps=4000;
boolean is_running= true;
void setup() {
  
  // put your setup code here, to run once:
pinMode(step_pin, OUTPUT);
pinMode(dir_pin, OUTPUT);


}

void loop() {
 
  
  digitalWrite(dir_pin,HIGH);

  if(is_running)
   {
    
   digitalWrite(step_pin, HIGH);
  delayMicroseconds(750);
   digitalWrite(step_pin, LOW);
   delayMicroseconds(780);
   i++;
    if (i==steps){
    is_running=false;
     }
   
    }



  
  
   

    
  /*delay(1000);
  // put your main code here, to run repeatedly:
digitalWrite(dir_pin,LOW);
for (i=0;i<steps;i++)
  {
digitalWrite(step_pin, HIGH);
  delayMicroseconds(350);
   digitalWrite(step_pin, LOW);
   delayMicroseconds(350);
  }
  delay(1000);*/
}

Check out my tutorial in Multi-tasking in Arduino which has a complete high speed stepper example which is controlled by user commands and a sensor.
There is a detailed explanation of how to measure and increase the maximum speed of the stepper using the AccelStepper library

@mbise1997, your topic has been moved to a more suitable location on the forum.

12V is a pretty low voltage if you want performance from your stepper motor,
24V or 36V would fare a lot better. Motor speed and torque-at-speed are mainly
controlled by winding inductance and supply voltage - please post your motor's
datasheet link or product page.
