I am running a 3 axis router on the above board with Vista. All three axis worked fine until I decided to upgrade, I replaced the lead screw, bearings, nut and motor for the Y axis, the Y axis works great however neither the X or Z work although you can hear the motors trying. I disconnected the new motor on Y axis, still nothing on the other two, I disconnected the X axis and connected it up to the working Y axis, works great. I checked voltage at the 5v and the output to each axis, all seem ok, could I have two blown chips? I am about ready to garbage this board and look at a Gecko.
