Hi, I have a problem which I hope someone can help me with. I had to move my cnc machine, after the move one of the axis stopped working. I replaced the aircraft connector, but still know joy. I replaced the stepper driver for a DM860A unit, still no joy. But now instead of having all green lights on the drivers, I now have the following. Two green leds, and the new driver a flashing red led. There is no drive from the DM860A. If I swap out the output block from a working driver, I still get know drive and the original working driver stops working also. I have rad that a flashing led means over voltage or over current. But I have know idea how to fault find this. Can anyone please help. Thanks
