[help] Adafruit stepper motor

by MrStein on Mon Dec 03, 2012 5:30 pm

hi all,
So, if I come on this forum is that I have a problem. I would like make this project
http://www.instructables.com/id/Polargraph-Drawing-Machine/step2/Parts/
which requires the use of Adafruit shield.

I bought this card:
http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=180970288137&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

The problem is that I can not even use the examples afmotor with a stepper motor (mine is a 200steps, 0.2A and 7.5v and i use a variable supply 1A) .. that make a step at right and a step at left but no rotation..
The center ship become hot too..

If i understood my code is that, with 200steps :
Code: Select all | TOGGLE FULL SIZE
#include <AFMotor.h>

// Connect a stepper motor with 48 steps per revolution (7.5 degree)
// to motor port #2 (M3 and M4)
AF_Stepper motor(200, 2);

void setup() {
  Serial.begin(9600);           // set up Serial library at 9600 bps
  Serial.println("Stepper test!");

  motor.setSpeed(10);  // 10 rpm   
}

void loop() {
  Serial.println("Single coil steps");
  motor.step(100, FORWARD, SINGLE);
  motor.step(100, BACKWARD, SINGLE);

  Serial.println("Double coil steps");
  motor.step(100, FORWARD, DOUBLE);
  motor.step(100, BACKWARD, DOUBLE);

  Serial.println("Interleave coil steps");
  motor.step(100, FORWARD, INTERLEAVE);
  motor.step(100, BACKWARD, INTERLEAVE);

  Serial.println("Micrsostep steps");
  motor.step(100, FORWARD, MICROSTEP);
  motor.step(100, BACKWARD, MICROSTEP);
}


Can someone help me? thank you!

(sorry for the English, I try to translate as best I can)

I'm sorry, that is not one of our shields. You should contact the company you bought it from for technical support.

it's my fault, I did not think it was a clone .. Yet the link on the card returns me on this forum but I will ask the seller.
You think the problem is the driver? it does not compatible with Adafruit products?

Thanks!
Pierre.

We do not manufacture this board, so we have no idea if it is compatible. In any case, the seller should not be using our link or logo without permission.
