[Homebrew_PCBs] Drilling station steppers, bipolar driver circuit

2005-06-22 by Robert Hedan

Darn,

It seems the circuit I had for unipolar steppers can be wired for bipolar
steppers as well.  I found a copy of it here, but there's just one problem:

Figure 9.1: http://eio.com/jasstep.htm#translators

"I think when you reverse direction and continue stepping, the motor will
advance 1 more step in the previous direction it was going before
responding."

Ugh...
