First thing take an ohm meter and "read" your coils. From any wire you
should have one other wire at a low resistance and two at a high
resistance. This will first determine if you have it wired right. On my
steppers the outside two form one coil and the inside two wires form the
other.

| Hi, everyone. I was wondering if somebody could help me. I am trying to control a 2 phase bipolar stepper motor. I found a web page at : (URL) talks about controlling bipolar stepper motors. But I just can't seem to make it work. When I use the code (...) (26 years ago, 1-Mar-99, to lugnet.robotics.handyboard)
