Be careful when you un hook the power supply from the driver.
The power supply probably has a capacitor that will give you a nice surprise, even if the box is unplugged. You probably already knew that,
but better safe than shorted.[/QUOT
That's definitely good info to keep in mind, because even a smaller capacitor may be capable of shorting something out. Some larger capacitors can be even worse, and short you out.
I don't know how much truth there is to It, but Some people say You discharge some capacitors by unplugging a unit, then turning on the power switch (if applicable) to drain what's left. Supposed to turn the power back off before plugging back in.
I wish I would have retained the knowledge better then I have, but a friend once told me of way to discharge capacitors using a high wattage resistor I think It was. He worked with larger capacitors that could give you quite a shock, so It was imperative from a safety standpoint to make sure there was no juice left.
Steve, now days, there's a lot of info out there available through a quick search, and I'm sure there's some good info on the best way to discharge them. May want to see what You can find that is more directly related to Your setup just to be on the safe side. I've worked on several types of electronics without doing It, and was fine, but I knew I was taking a chance, and what I was working was not as expensive as a controller or drivers for a cnc. Some PC boards are so sensitive that even static electricity can do damage, so who's to say what a charged capacitor can do.
Wish I could help with the driver Issue Your having, but that's still over My head, and best I could do is take guesses at it, which is of no real use anyhow. Hope the new driver solves your problem though.
