Arduino & TB6560 3 Axis

best regard

i have driver tb6560 3 axis (see attached image) works following code arduino mega.

code: [select]



byte directionpin = 9;
byte steppin = 8;
int numberofsteps = 10000;
byte ledpin = 13;
int pulsewidthmicros = 10;  // microseconds
int microsbetweensteps = 1; // milliseconds

void setup() {

  serial.begin(9600);
  serial.println("starting steppertest");
  digitalwrite(ledpin, low);
 
  delay(2000);

  pinmode(directionpin, output);
  pinmode(steppin, output);
  pinmode(ledpin, output);
 
 
  digitalwrite(directionpin, high);
  for(int n = 0; n < numberofsteps; n++) {
    digitalwrite(steppin, high);
    delaymicroseconds(pulsewidthmicros); // line unnecessary
    digitalwrite(steppin, low);
   
    delay(microsbetweensteps);
   
    digitalwrite(ledpin, !digitalread(ledpin));
  }
 
  delay(3000);
 
  digitalwrite(directionpin, low);
  for(int n = 0; n < numberofsteps; n++) {
    digitalwrite(steppin, high);
    // delaymicroseconds(pulsewidthmicros); // not needed
    digitalwrite(steppin, low);
   
    delay(microsbetweensteps);
   
    digitalwrite(ledpin, !digitalread(ledpin));
  }
}

void readpotentiometer()
{
const byte potpin = a0;
int potvalue;

potvalue = analogread(potpin);
 
}

void loop()
{
}



my question is, serves (pulsewidthmicros) , (microsbetweensteps), if put pin high step in without delay advancing? or refers motor stepper used?

thank you

i'm sorry don't understand question.

i don't think there need small delay between digitalwrite(steppin, high) , ...low) because digitalwrite() function slow enough give adequate pulse width. if motor not working uncomment line pulsewidthmicros see if improves matters.

the variable microsbetweensteps governs speed @ steps sent motor.
