Hi All,
 Sadly my Gecko540 gave up on me, although I changed the fuse it sounds like there is a short somewhere whic I cant' find, I had bought some time ago a package of a breakout board and driver board. The breakout board connects to the computer with the same  parallel  cable as the gecko did. I have power to both boards red lights and if I use the key board I have green lights on the driver board each motor and the DRO's move, BUT I have no power or movment of the steppers.
What have i missed?? I have run the driver test in Mach3, I have run at 100k other wise it say it is to fast on other setting but I have an very good on this setting.
Mike
