I'm not good at electronics, so this is probably a dumb question.
I have been running one Gecko driver to test/run one motor on my unfinished machine. I have now reached the point where i want to run all three motors. I wired three geckos and three motors. OK, everything is wired except the "Common" or "+5Volt" on the drives for the Opto Isolators. Question is where do I get +5Volts from? Where would I wire the ground to the +5Volts? Before I was just getting it from a Hi pin on the parrallel port, but this don't seem to be working with 3 drives.
Help me before I make smoke....
Thank You
