As you can see I'm using an Arduino Pro (the blue PCB) to generate the step pulses and the step direction, alternating between a high frequency and low frequency and changing direction. The motors both respond nicely. The red PCBs are the EasySteppers.
Tonight I attached all the wiring and tried to get EMC to control the motors, sadly I was unsuccessful. I think I am having issues with the parallel port card. Maybe I've got the wrong address or something. I'll have to sit down tomorrow and troubleshoot this one. I'd also like to make a small PCB that holds a 12V-5V convertor, some LEDs, DB25 and a relay for the emergency stop. Gotta sleep on that one.
