Or do you just want them to move? You should read the data sheet of the stepper driver IC. But usually its like this.. there is an ENABLE pin… make it high.. There will be a STEP pin this will need to “pulse” so 010 would make it step 1 position. There is also a DIR pin. Not reading the datasheet (in quite awhile) DIR 0 = right? 1 = left? (BTW STEP = 010 meant LOW HIGH LOW)

Psedo Code:

ENABLE = 1;
DIR = 1; //goes right? I think
for(;;) //an infinite loop.. The motor will just spin forever.
{
STEP = 1
DELAY_MS(100) //whatever value you want
STEP = 0
DELAY_MS(100)
}

So turn that code into arduino. I cant stress enough that you should read the datasheet on the IC that your stepper driver is using.

I have tried to answer your question… But this kinda not the right place to put this. Not that I mind. Just saying if you went to contraptor.org’s forums you would get more input than what I have. Also, perhaps you go to the reprap/makerbot forums.

This link might help also.

Hope this helps bud.

I have built the stepper motor drivers based on the reprap design and have them working, But im looking for what gets loaded onto the Arduino? I cant find any mention of the Arduino Source code, Or is that whatever you wish it to be?
