Hi to all. Im Alberto, and using the GREAT and TERRIFIC ammount of info I found in the site Im finishing a 4 axis interface card and one discrete unipolar driver card.
I have some experience building machine-tools and even making and mounting PCBs, but NOTHING about electronics.
My first answer is: Im planning to test the cards connecting the interface to the parallel port, then the driver card to a 5 wire stepper and a 5V DC power suply, then watch what happens running Mach3 or Kcam... thats madness? please anyone tell me something about it.
Second answer: I have a parallel cable I used to hook-up printer port to scanner, then another from scanner to printer. Is the first one suitable to hook up the parallel port to 4 axis interface?
Please dont laugh about my ignorance!! I did several projects these way, someones works at the first try, and some others burn. Make some bets about these one.
