I was just futsing with 5vdc connection from Kanalog to my bus that supplies 5v signal voltage to my drives, and I could cause the steppers to engage a second clunk. I checked the voltage coming out of KAnalog and it appeared that around 9vdc out of JP8. My 5vdcsupply was putting out the same. I disconnected the supply at this point, but I'm surprise that the board wasn't just fried from getting 9v. I have no idea why my supply is putting out 9v all of a sudden. Tom, this is a supply that you recommended to me some time last year, and has been solid to this point.
