Hi All, So I just got one of these cards and a bunch of new DM542 drivers and now the steppers are moving great on Mach3. I am down to one problem. I don't have a physical E-stop button, but there is the red button in the software in Mach3 that I use. The button is working great to stop any running cutting program. The problem I have is that when I hit the E-stop it does not release the stepper motors. They are still locked in tight until I physically unplug the power supplies. Is there something I'm setting wrong someplace ??? Thanks Steven
