  Hi, Love your site and projects. Im interested in the Contraptor project you are/were working on. Im looking where to get the source code for the Arduino Module. I have all the files for the drivers but no Source. Any help would be great, just cant seem to find it
  .
  Cheers
  John

  John,
  Could you be more specific? What code / project are you talking about? Contraptor can be found here:

  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?

  So I am still not sure what you are wanting to do with your stepper drivers? YOu can use replicatorG which is a firmware that will “digest” gcode and toss it into STEP DIR (which is what the drivers you built will consume).

  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.
