trying control a stepper having no luck any help

I am new this and don't know anything about programing or stepper motors I have done some things with the Arduino before like the led project made a lathe do a break in on one of our products with the Arduino.I am having no luck with this one though he we go what I am using an
Oreintal Motor and driver that has a 5V Step and Direction pins to make the motor move. I have tried to use other examples of code I found on here stepper motors but none have worked for me. The model number of the controller and motor I am is RBK264PAR26-P36 this is a link to the page about it there is a user manual there in pdf form http://catalog.orientalmotor.com/item/all-categories/-microstep-rbk-series-2-phase-microstepping-motors/rbk264par26-p36?plpver=11&categid=100&prodid=3001079&origin=keyword I
Hopefully someone can help me out this is the code I was trying to use

// Givens
long ta = 1e6; // acceleration time (microsec)
long td = 1e6; // decelleration time (microsec)
long Vm = 3200; // steady state velocity (pulse/sec)
long Pt = 12800; // total number of pulses for move (1600 steps per rev)

// Other variables
long dly; // stepper pulse delay (microsec)
long t = td/9; // current time (microsec) - You need to seed the initial time with something > 0
// so you don't calculate to long of a delay
long t12; // time during constant velocity (microsec)

int count = 0; // count the number of pulses
int Perr = 0; // error in position

// Arduino pins
#define dirPin 3
#define stepPin 12

void setup() {
Serial.begin(9600);
pinMode(dirPin, OUTPUT);
pinMode(stepPin, OUTPUT);

// Calculate the time at constant velocity
t12 = (Pt/(Vm/1e6))-0.5*(ta+td);
Serial.println(); Serial.println();

Serial.println("Setup Done");
}
void loop()
{
digitalWrite(dirPin, HIGH); // Set the stepper direction

// Decide which part of the velocity curve your at
if (t<ta) { // Acceleration
//Serial.println ("Acceleration Curve");
dly = (ta)/(2*(Vm/1e6)t);
}
else if (t>=ta && t<(ta+t12)){ // Constant velocity
//Serial.println ("Constant Velocity");
dly = 1/(2
(Vm/1e6));
}
else if (t>=(ta+t12) && t<(ta+t12+td)){ // Deceleration
//Serial.println ("Deceleration Curve");
dly = 1/(2*((Vm/1e6)-(Vm/(1e6td))(t-ta-t12)));
}

t = t+2*dly; // update the current time
//Serial.print("dly: "); Serial.print (dly); Serial.println(" microsec");
//Serial.print ("Current time: "); Serial.print(t); Serial.println(" microsec");

// Move stepper one pulse using delay just calculated
digitalWrite(stepPin, HIGH);
delayMicroseconds(dly);
digitalWrite(stepPin, LOW);
delayMicroseconds(dly);
count ++;

// The move is finished
if (t>(ta+t12+td)){
Serial.println ("Move Complete");
Serial.print ("Total steps indexed: "); Serial.println (count);

// Correct for any position error due to rounding
Perr = Pt-count;
if (Perr < 0) {
digitalWrite(dirPin, 1^digitalRead(dirPin)); // reverse the stepper direction
delay(50);
Perr = -1*Perr;
}
for (;Perr>0;){
digitalWrite(stepPin, HIGH);
delayMicroseconds(dly);
digitalWrite(stepPin, LOW);

}

Can you explain more about how you are connecting things? Have you verified the controller is using step/direction ?

Yes the controller is using step and direction. I am connecting everything the way manual said for the input signals connecting the step pulse pin #1 on the controller to pin #12 on my arduino and the direction pulse pin#3 on the controller to pin 3 on an my arduino.

Hi, I would suggest you start simple to see if the motor and controller work.

  • Tie direction to either Gnd or +5

  • Load the GOBP (Good old Blink program) in your arduino examples.

  • Connect STEP to pin 13.

The motor should take a small step every 2 seconds. Change blink to about delay(50); and the motor should step faster.

When that works, dig into that complicated code...

Thank you for the help I was able to get it working finally it was something really stupid that I over looked now it is working fine.
again thanks for the help really appreciated
